goldquest 1400 impact mill - gold prospecting mining equipment detectors snake protection
This NEW impact mill has been more than two years in the making, but the manufacturer wanted to make sure it was state of the art and something to be proud of! This rock crusher offers features not found on other units feet that can be bolted down in place, an octagon shape for better breaking capacity, breaker bars to make it even more effective, powerful forged clevis hooks for hammers this is a real workhorse! In most cases, this unit can ship in 1 to 2 weeks from ordering.
This crusher will make powder from 100 to 300 mesh in seconds IF you want that. But if you don't, and in many cases you do NOT want it that fine, you have options. For example, if you have visible gold in the 20 to 50 mesh range, would it not be nicer to liberate that gold at that size instead of smashing that 20 to 50 mesh gold down to 300 mesh so your only option is to use chemicals like cyanide to get your free milling gold? In days of yore, the stamp mills knew that crushing it too fine meant you had to go the extra mile to get it back. If you have plainly visible gold, leave it at a manageable size. You can always change out the
screens and run the tailings again to get the ultra fine 300 mesh.
Using a 3/4 inch keyed shaft with a direct drive coupler, you don't have to worry about belts coming loose or wearing and breaking. With the use of several collars, everything stays where it's supposed to. Forged clevis hooks are the easiest to change out if needed. The forged clevis hooks give the ore an extra solid punch instead of chains. It's easy to open the door! NO tools required. Six hand-tightened thumbscrews and a lever opens the mill up in no time for cleaning or maintenance and also keeps the 10 gage door tight against the hard neoprene rubber door seal. A back plate has been added to the rear to protect the bolt heads from wearing off.
The dual grizzly bar output is very functional and highly customizable! The screen floats between the pair of grizzly bars letting the screen vibrate to increase output flow. It's only a matter of loosening up the two nuts to change screens to a coarser or finer screen, double up the screens, or no screen at all. Being at 2-7/8 x 4 inch, it's a large port.
Having the Goldquest 1400 mounted on the tailgate of a truck, and having the discharge fed directly into a Gold Cube will catch all that fine visible gold! Feed in a ton, take home just a cup of concentrates.
BONUS: If you already own a Crazycrusher manual rock crusher with hitch mount, you would be glad to know that the Goldquest 1400 Rock Crusher fits the same hitch mount as your Crazycrusher does (only different bolts are needed.)
small hammer mill grinding
Our high-performance impact crusher or better known for good small scale Hammer Mill Grinding. Specially engineered to outperform those run-of-the-mill chain mills often falsely called hammer mills. This crusher is effectively a small-scale replica of industrial impactors.
In this rock-crushing machine, rock is projected against the inner cage and shatters by impact. At 1750 RPM, the AR-450 blow-bars throw the material to be crushed onto another set of abrasion-resistant wear-plates.
As impact crushing becomes more prevalent in the production of friable as well as some harder types of aggregates, it is natural for those not completely familiar with the process, or recent improvements in technology, to wonder why impactors are being specified in situations previously often considered uneconomical or, at best, marginally feasible for this type of equipment. The simple answer is that the rules for determining the economic feasibility of utilizing impact systems have changed over the last few years, and are continuing to change at an accelerating pace.
Before discussing the new economics of impact crusher usage, it might be well to briefly state the original, and still valid, advantages of the impact crusher in the production of friable aggregates. Low original cost has always been the primary advantage of this equipment. For a given application this first cost may well be only a quarter as much as for compression type crusher installation. Second, a greater reduction ratio can be achieved. Many installations are now producing specification stone from run-of-quarry feed in a single pass through a primary impact unit. Third, impact crushers are capable of accepting larger feed sizes, with units now in operation handling feed sizes in excess of 65 x 65 x random length. This larger feed size capability reduces material hang-up in the feed hopper and the need for use of either secondary blasting or a headache ball to reduce oversize rock in the quarry prior to transporting it to the primary crusher. And fourth, impact crushing, by its very nature, produces a higher quality product. It produces a dense, cubical product without the slivers or slabs prevalent in other methods, making it easier for plant operators to meet the stringent specifications laid down by many customers.
Each of these inherent advantages leads automatically to certain economic advantages, as well as to some recognised disadvantages. However, some of the potential economies have not, until recently, been fully exploited. Nor is it well known among all producers how some of the old disadvantages have been overcome in some of the newer units and systems now appearing in newer quarries.
Briefly, compression is the forcing of two surfaces toward one another to crush the material caught between them. Impact crushing can be of two variationsgravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate.
Design improvements in many of the impactors being manufactured today have a great deal to do with changing earlier ideas concerning the economics of this type of equipment vs. nominal installations. But, of equal importance, is the systems design approach now being offered by the leading manufacturers to solve aggregate production problems. In any technology, when a thorough systems design approach is undertaken in an effort to better utilize the inherent advantages of a specific product, the results may be much more rewarding than mere use of the product advantages by themselves. This is proving true in aggregate production as more quarry operators are calling in impactor manufacturers during the early planning stages and letting them design complete production systems that utilize all the advantages of todays crusher technology.
The flow diagram at the left is from one manufacturers brochure. He uses it to indicate not only that he welcomes the opportunity to custom engineer a complete system for his customers, but also to show through call-outs, which have been deleted for this article, that his company actually designs and manufactures about ninety percent of the machines, parts, assemblies and other items necessary for this type of total plant.
This willingness by the leading crusher manufacturers to assume total responsibility for turnkey installations has forced technological improvements that might still be years away if manufacturers still sold, and the industry still purchased, only bits here and pieces there. One leading manufacturer readily admits that improvements he has made in his crushers have forced changes in his lines of material handling equipment; that changes in quarrying techniques and demands for increased capacity have speeded improvements in his crusher design, screening systems, conveyor parts and systems, feeder arrangements, and drying and storage equipment; that sometimes these domino-type changes go full circle and start yet another round of changes and improvements, all of benefit to the system buyer, and many of which might never have been made were they not caused by total systems development responsibility.
Along with these chain effect improvements in complete aggregate processing systems are the steady and, in some cases, almost dramatic improvements made in impact crushers themselves. Considerable R&D work by leading manufacturers has led to larger, more versatile, more durable, and more efficient impact crushers in recent years that are much easier and more economical to maintain. Crushing equipment, whether primary or secondary in nature, represents one of the most important aspects in the overall operation of minerals* processing.In an area which includes the vast range of ores, minerals, coals, stone and rocks, etc., a processing plants crusher selection must be given special consideration. Performance, cost, availability and versatility are the prime goals.
Crusher Selection For the crusher to perform its role in the processing cycle with maximum efficiency and economy it must be matched to the task. Determining factors in crusher selection break down into four categories: material to be crushed; feed size; product size; and expected capacity. The right crusher should also have the lowest power requirements per ton of finished product, and operate with minimum maintenance and downtime. There are a variety of crushers to meet the needs of todays industrial requirements. Exactly how is a determination made on the proper crusher? Extensive study and evaluation of the above facts concerning material, feed size, etc. will be an essential guideline. Next to be considered is the actual mechanical method of crushing to be used. Generally, crushing methods include compression, impaction, attrition, and shearing.
