large industrial rock crushers
Our Large Industrial Rock Crushers employ two planer-crushing surfaces set at a small angle to each other and convergent downward. One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitman-toggle arrangement activated by an eccentric drive. The 3 common variations of the jaw crusher drive system are described here.
The Blake features a double togglejaw crusher drive mechanism which gives relatively smaller movement at the receiving end of the chamber generating a powerful crushing action for large rock pieces. A refinement on the crusher illustrated is the use of a curved jaw plate on the swing jaw which renders the crusher non-choking. This curvature decreases the effective receiving opening but does prevent choking and thereby increased capacity. A high-capacity Blake has subsequently been manufactured which has a decreased crushing angle and several altered structural design details. This type of crusher is now more commonly installed unless the prime objective is to have a maximum receiving opening for hard and coarse feed. The single toggle jaw crusher is similar to the Dodge type in that maximum movement is at the receiving opening but in all other respects compares with the Blake type. The actual crushing motion is somewhat complicated consisting of vertical as well as horizontal components. The machine is popular for its simplicity, lightweight, moderate cost, and ease of adjustment as well as its high capacity and high reduction ratio. It is particularly applicable for portable crushing rigs. Its disadvantages are the high wear of jaw plates due to the vertical component of movement and its vulnerability to bearing damage due to shock loading.
On the bottom right, theDodge jaw crusher uses a variation of design in which the swing jaw is pivoted at the bottom and the entire section is driven by a pitman without the knee-action of a toggle. The basic difference is that maximum movement is at the feed opening and consequently the point of least movement is at the feed opening and the choke-point coincide, greatly hindering the capacity of such a machine. Furthermore, the relatively rapid movement at the top tends to pack the lower regionsrendering the machine incapable of treating soft, friable materials. The advantages of the Dodge type is its simplicity, ease of adjustment and maintenance, low cost and its ability to operate at a high reduction rate. These features make it a popular machine for laboratories and industrial applications where the crushing rate is not as important as producing a fine product.

Exhibiting powerful design and rugged durability, the Willpactor is perfect for primary rock crushing applications. Willpactors thrive in high-capacity applications crushing large run-of-mine rock, with machines available in sizes to accommodate 44 to 72 rock. External product size adjustment and solid impact block adjustment are just some of the features of these rock crushing machines.
The Willpactor II handles feed sizes beyond the range of conventional secondary and tertiary crushers. A large feed opening, contoured hi-chrome rotor, and easy maintenance are just a few of the features that make the Willpactor II impact rock crusher machine a great asset for any rock crushing application.

Rock crushers have a wide range of suitable material to choose from, whether its soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust.Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone, calcite, concrete, dolomite, iron ore, silicon ore, basalt and other mines, rocks and slag.
Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.
Similarly, a certain output is expected at the end of each crushing stage for the next phase of the process. Aggregate producers who pair the correct crusher to the correct stage will be the most efficient and, in turn, the most profitable.
A jaw crusher is a compression type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The discharge size is controlled by the setting or the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.
As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.
Although the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead, a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized.
An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. The secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.
Impact crushers tend to be used where shape is a critical requirement and the feed material is not very abrasive. The crushing action of an impact crusher breaks a rock along natural cleavage planes, giving rise to better product quality in terms of shape.
Most aggregate producers are well acquainted with the selection of crushing equipment and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. Still, theoretical conclusions must always be weighed against practical experience regarding the material at hand and of the operational, maintenance and economical aspects of different solutions.
The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best choice.
The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.
A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted.
The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.
In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is to obtain the greatest possible reduction at the lowest possible cost.
In most cases, the fine crushing and cubicization functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.
