Crusher/Destemmers are used to first crush wine grapes and then separate the grapes from the stems. The manual model is appropriate for small lots of grapes, while the motorized versions become a necessity for larger volumes. The machines are made for us in Italy and feature our MoreWine! brand name. We maintain a careful involvement in the manufacturing process. By offering what have historically been our most popular models we are able to stock replacement parts, though in truth we rarely sell any of them!

grape crusher : 5 steps - instructables

grape crusher : 5 steps - instructables

I own a house with a 40+ year old concord grape vine that produces more grapes than I know what to do with (they have seeds so I don't end up eating many of them). I also have a cool basement and room for projects, and this year I've decided to try to make wine. Having tried to make jam with the grapes last year, I've already learned that smashing grapes with a potato masher is both time consuming and no fun. It also isn't very effective. I visited my local brew @ home store and got a quick run through of the process of making wine, and all the basic materials. The store manager estimated that I had over 100lbs of grapes which could produce close to 10 gallons of juice. From what I remember last year, we took about 15 lbs of grapes (stems and all) and got about 1 gallon of juice after 45min of mashing and squeezing through a cheese cloth. If we want to get through all 100lbs....there had to be a moreefficientway. My basic plan was to use a car jack to push a disk into a perforated stock pot, to crush the grapes. In the next few pages you'll see the contraption I came up with.

I didn't want to spend too much on this grape crusher since I could buy a tried and true one off of ebay for ~$180. Materials: Large stock pot from Goodwill - $15 (2) 2x4s that were laying around - $Free (2) 14" x 14" pieces of 3/4" plywood that were laying around - $Free (2) flimsy plastic cutting boards from the kitchen - $Free 3' of quarter round trim - $3 Brad nails - $1 2.5" Lag bolts & washers - $6 2" screws laying around - $Free Car jack - Borrowed from the car 6mil plastic sheet - $10 Note: I used flimsy cutting boards because they are cheap and I had them. If I had old thick plastic cutting boards laying around I would have used those instead. All I was trying to do was create a barrier between the plywood and the grapes. Tools: Compound miter saw to cut 2x4s Circular saw to cut the plywood Jig saw to cut plywood disk Hammer for the holes in the pot and the brad nails Sander (if necessary) Scissors to cut the cutting board

The pot I got from Goodwill need some holes which I thought I was going to have to tediously drill one at a time. It turns out that since itsaluminum, I didn't have to do that. All I needed was a hammer and a nail.

Now that I had a pot and knew its dimensions, I need to create a disk that would fit snugly in the pot and spread out the force of the car jack on the grapes in the pot. I had some old flimsy cutting boards laying around, so I cut one with scissors to fit inside the pot. I then used that as a template for the plywood disk, which I cut with a jig saw. The disk wasn't perfect, but after a few test fits and sanding it fit nicely. (if you're a perfectionist use a router with a circle cutting jig to cut the disk)

Now that the plunger was created, I needed a sturdy frame for the pot and car jack to sit within. The frame has to contain the force of the jack on the top and the bottom; the force of the jack pushing off the top of the frame and against the pot full of grapes that is supported by the bottom of the frame. I knew the pot was a little less than 14" in diameter, 10.5" tall, and that the jack's range of movement was between 7.5" and 15". As such the inside of the frame would be 14"x14" and 20" tall toaccommodatethe jack, plunger disk, pot, and a little bit of fudge room. To support the jack on top I placed a 2x4 cross beam, and on the bottom, a base of plywood. I cut the plywood to form a base within the frame, and nailed pieces of quarter round trim on 3 sides. If all goes according to plan, when the juice oozes out of the pot, it'll land on the 14x14 cutting board (that is sloped by the quarter round), and run off the base and into a plastic tub. I cut the 2x4s for the frame to size, pre drilled holes for the lag bolts, and screwed it all together. I used lag bolts where it mattered as I didn't want the weakest part of the frame to be the joints. Even though I don't anticipate needing a bunch of force to crush the grapes, by using a car jack that can lift 1 ton, screws just weren't going to cut it. I also built guides to keep the jack from slipping off the 2x4 on the top, and the disk that will be in the pot.

Here you can see the whole contraption. To use it we'll start with washed & stemmed grapes in the pot, then add the round cutting board, a 3' x 3' 6mil plastic sheet (to create a waterproof barrier between the grapes and the chemical laden plywood), the plywood plunger disk, and then the jack. We'll turn the screw on the jack which will force the jack & plunger disk into the pot, compressing the grapes and letting juice run out of the holes and into the tub. There shouldn't any liquid shooting out of the holes as the jack will move slowly, so the way its set up now should be fine. If things get ugly we can always wrap the inside of the frame with the 6mil plastic to contain the mess. Theoretically this thing can crush any fruit you'd want. The only limitation is the amount of pressure the frame can handle from the jack. The jack will win if we push it, but I can'tforeseeany need for that much force, no matter what fruit we're trying to crush. As much of my design was due to the materials I had at hand, please consider this more of a guide than a step by step plan. Your intended use may also change the design and materials that you choose to use, so have fun with it. (if you decide to take it to the extreme and build a welded steel frame with a hydraulic jack, please send pics and video!) More pics to follow once we've put the crusher to use. I'm entering this into the Epilog Challenge, and if I win, I'll use the laser engraver to make custom wine bottle labels.

grape crushers - crushers and presses - winemaking

grape crushers - crushers and presses - winemaking

Crushing grapes or fruit prior to the primary fermentation helps to breakdown the fruit pulp and allows the juice to flow out so that it can mix with the yeast for fermentation. For small batches of grape or fruit wine (less than 5 US gallons), Grape and Granary recommends a small crusher such as the Vintage Shop Fruit Crusher. It does not remove stems but is perfect for crushing berry fruits and works well for small batches of grape wine. For the more serious winemaker making 10 gallon batch sizes or more, a more sizable crusher is needed. A manual crusher with a Destemmer is ideal for making red wine from grapes. Removing stems by hand or with a paddle can be tedious and time consuming. Leaving too much stem material in a batch of wine can lead to vegetal flavors and an overly tannic wine. A machine that can crush the fruit and remove the stems in one step will save great amounts of work and make better wine. The destemming screen can be removed for cleaning or the production of white wine (when stems will be left in for easier pressing of white grapes). For those producing only white wines or smaller batches, a grape crusher without a destemming screen will do the trick. The serious or semi-professional winemaker will likely want a Motorized Crusher/Destemmer which can plow through 1.5 tons of grapes per hour and remove the stems at the same time.

jaw crusher working principle

jaw crusher working principle

A sectional view of the single-toggle type of jaw crusher is shown below.In one respect, the working principle and application of this machine are similar to all types of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being the resultant of the circular motion of the eccentric shaft at the top of the swing jaw. combined with the rocking action of the inclined toggle plate at the bottom of this jaw. The motion at the receiving opening is elliptical; at the discharge opening, it is a thin crescent, whose chord is inclined upwardly toward the stationary jaw. Thus, at all points in the crushing chamber, the motion has both, vertical and horizontal, components.

It will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.

The horizontal component of motion (throw) at the discharge point of the single-toggle jaw crusher is greater than the throw of the Dodge crusher at that point; in fact, it is about three-fourths that of Blake machines of similar short-side receiving-opening dimensions. The combination of favorable crushing angle, and nonchoking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the Dodge crusher. Capacities compare very favorably with comparable sizes of the Blake machine with non-choking plates, and permissible discharge settings are finer. A table of ratings is given.

The single-toggle type jaw crusher has been developed extensively. Because of its simplicity, lightweight, moderate cost, and good capacity, it has found quite a wide field of application in portable crushing rigs. It also fits into the small, single-stage mining operation much better than the slower Dodge type. Some years since this type was developed with very wide openings for reduction crushing applications, but it was not able to seriously challenge the gyratory in this field, especially when the high-speed modern versions of the latter type were introduced.

Due to the pronounced vertical components of motion in the single-toggle machine, it is obvious that a wiping action takes place during the closing strokes; either, the swing jaw must slip on the material, or the material must slip along the stationary jaw. It is inevitable that such action should result in accelerated wear of the jaw plates; consequently, the single-toggle crusher is not an economical machine for reducing highly abrasive, or very hard, tough rock. Moreover, the large motion at the receiving opening greatly accentuates shocks incidental to handling the latter class of material, and the full impact of these shocks must be absorbed by the bearings in the top of the swing jaw.

The single-toggle machine, like the Dodge type, is capable of making a high ratio-of-reduction, a faculty which enables it to perform a single-stage reduction of hand-loaded, mine run ore to a suitable ball mill, or rod mill, feed.

Within the limits of its capacity, and size of receiving openings, it is admirably suited for such operations. Small gravel plant operations are also suited to this type of crusher, although it should not be used where the gravel deposit contains extremely hard boulders. The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain.

As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particles weight and the friction between it and the crusher surfaces counteract this tendency. In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage.

Leading is a technique for measuring the gap between fixed and moveable jaws. The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle. The minimum safe closed side setting depends on:

Blake (Double Toggle) Originally the standard jaw crusher used for primary and secondary crushing of hard, tough abrasive rocks. Also for sticky feeds. Relatively coarse slabby product, with minimum fines.

Overhead Pivot (Double Toggle) Similar applications to Blake. Overhead pivot; reduces rubbing on crusher faces, reduces choking, allows higher speeds and therefore higher capacities. Energy efficiency higher because jaw and charge not lifted during cycle.

Overhead Eccentric (Single Toggle) Originally restricted to sampler sizes by structural limitations. Now in the same size of Blake which it has tended to supersede, because overhead eccentric encourages feed and discharge, allowing higher speeds and capacity, but with higher wear and more attrition breakage and slightly lower energy efficiency. In addition as compared to an equivalent double toggle, they are cheaper and take up less floor space.

Since the jaw crusher was pioneered by Eli Whitney Blake in the 2nd quarter of the 1800s, many have twisted the Patent and come up with other types of jaw crushers in hopes of crushing rocks and stones more effectively. Those other types of jaw crusher inventors having given birth to 3 groups:

Heavy-duty crushing applications of hard-to-break, high Work Index rocks do prefer double-toggle jaw crushers as they are heavier in fabrication. A double-toggle jaw crusher outweighs the single-toggle by a factor of 2X and well as costs more in capital for the same duty. To perform its trade-off evaluation, the engineering and design firm will analyze technical factors such as:

1. Proper selection of the jaws. 2. Proper feed gradation. 3. Controlled feed rate. 4. Sufficient feeder capacity and width. 5. Adequate crusher discharge area. 6. Discharge conveyor sized to convey maximum crusher capacity.

Although the image below is of a single-toggle, it illustrates the shims used to make minor setting changes are made to the crusher by adding or removing them in the small space between the crushers mainframe and the rea toggle block.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher.

Crusher must be adjusted when empty and stopped. Never close crusher discharge opening to less than minimum opening. Closing crusher opening to less than recommended will reduce the capacity of crusher and cause premature failure of shaft and bearing assembly.

To compensate for wear on toggle plate, toggle seat, pitman toggle seat, and jaws additional shims must be inserted to maintain the same crusher opening. The setting adjustment system is designed to compensate for jaw plate wear and to change the CSS (closed side setting) of the jaw crusher. The setting adjustment system is built into the back frame end.

Here also the toggle is kept in place by a compression spring. Large CSS adjustments are made to the jaw crusher by modifying the length of the toggle. Again, shims allow for minor gap adjustments as they are inserted between the mainframe and the toggle block.

is done considering the maximum rock-lump or large stone expected to be crushed and also includes the TPH tonnage rate needing to be crushed. In sizing, we not that jaw crushers will only have around 75% availability and extra sizing should permit this downtime.

As a rule, the maximum stone-lump dimension need not exceed 80% of the jaw crushers gape. For intense, a 59 x 79 machine should not see rocks larger than 80 x 59/100 = 47 or 1.2 meters across. Miners being miners, it is a certainty during day-to-day operation, the crusher will see oversized ore but is should be fine and pass-thru if no bridging takes place.

It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. The seating (234) of the rear toggle plate (239) is fixed to the crusher frame; the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. Thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return half-stroke until eventually the pieces have been broken small enough to drop out. It follows that the size to which the ore is crushed.

The jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is difficult to keep it working at its full capacity that is, at maximum efficiency.

Tables 5 and 6 give particulars of different sizes of jaw crushers. The capacity figures are based on ore weighing 100 lb. per cubic foot; for a heavier ore, the figures should be increased in direct proportion to its weight in pounds per cubic foot.

The JAW crusher and the GYRATORY crusher have similarities that put them into the same class of crusher. They both have the same crushing speed, 100 to 200 R.P.M. They both break the ore by compression force. And lastly, they both are able to crush the same size of ore.

In spite of their similarities, each crusher design has its own limitations and advantages that differ from the other one. A Gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. Its design allows a higher-speed motor with a higher reduction ratio between the motor and the crushing surface. This means a dollar saving in energy costs.

A Jaw crusher on the other hand requires an Ely wheel to store energy. The box frame construction of this type of crusher also allows it to handle tougher ore. This design restricts the feeding of the crusher to one side only.

The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks. The broken ore then falls through the crusher to be taken away by a conveyor that is under the crusher.Although the jaws do the work, the real heart of this crusher is the TOGGLE PLATES, the PITMAN, and the PLY WHEEL.

These jaw crushers are ideal forsmall properties and they are of the high capacity forced feed design.On this first Forced Feed Jaw Crusher, the mainframe and bumper are cast of special alloy iron and the initial cost is low. The frame is ribbed both vertically and horizontally to give maximum strength with minimum weight. The bumper is ruggedly constructed to withstand tremendous shock loads. Steel bumper can be furnished if desired. The side bearings are bronze; the bumper bearings are of the antifriction type.

This bearing arrangement adds both strength and ease of movement. The jaw plates and cheek plates are reversible and are of the best-grade manganese steel. The jaw opening is controlled by the position of an adjustable wedge block. The crusher is usually driven by a V-to-V belt drive, but it can be arranged for either V-to-flat or fiat belt drive. The 8x10 size utilizes a split frame and maybe packed for muleback transportation. Cast steel frames can be furnished to obtain maximum durability.

This second type of forced feed rock crusher is similar in design to the Type H listed above except for having a frame and bumper made of cast steel. This steel construction makes the unit lighter per unit of size and adds considerable strength. The bearings are all of the special design; they are bronze and will stand continuous service without any danger of failure. The jaw and cheek plates are manganese steel; and are completely reversible, thus adding to their wearing life. The jaw opening is controlled by the position of an adjustable wedge block. The crushers are usually driven by V-to-V but can be arranged for V-to-flat and belt drive. The 5x6 size and the 8x10 size can be made with sectionalized frame for muleback transportation. This crusher is ideal for strenuous conditions. Consider a multi jaw crusher.

Some jaw crushers are on-floor, some aboveground, and others underground. This in many countries, and crushing many kinds of ore. The Traylor Bulldog Jaw crusher has enjoyed world wide esteem as a hard-working, profit-producing, full-proof, and trouble-free breaker since the day of its introduction, nearly twenty years ago.

manual grape and fruit crushers - the 4 best options - wine makers corner

manual grape and fruit crushers - the 4 best options - wine makers corner

When you get into winemaking with real fruit you will have to start to invest in more equipment like manual grape and fruit crushers. Crushing fruit is very important in the winemaking process because it allows the maximum amount of juice to be extracted. This is why you would see those old-time pictures of someone stepping on grapes, to release the juices and get the wine flowing. Crushing is the first step that turns the fruit into delicious and shelf-stable wine. As grape skins are broken by the crusher the sweet juice comes into contact with the grape skins allowing the flavor, colors, and tannins to be absorbed into the juice. This is crucial for fine wines. Skin contact time is essential for red wine and other fruit-based wines. Weve put together a list of some of the best manual grape and fruit crushers available online.
