The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.

To reduce large and bulky materials to a manageable size. Jaw Crusher: 500 mm to 800 mm: Reduced to about 125 mm to 150 mm. ... and the required size reduction. For large, heavy-duty operations, a double-toggle jaw crusher is often the go-to. For smaller, less intensive tasks, a single toggle might be more appropriate.

Basic ways to reduce material size. Crushing is the process of reducing or breaking down larger-sized material into smaller-sized material. There are four basic ways to crush. ... They provide a reduction ratio of 3:1 to 6:1. Jaw Crushers feature a moving piece of steel (called the pitman) and a stationary piece of steel that form a V-shaped ...

It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates. Jaw crushers are typically used in the mining and construction industries, as they can handle large rocks and reduce ...

A jaw crusher is a crucial component in mining and ore processing plants, performing the primary crushing of rock and mineral ore to reduce and control the size of materials for further sizing, shaping, beneficiation and processing. These compression crushers are designed to tackle dry to slightly wet materials, without stickiness, and are ...

One really handy thing about jaw crushers is that you can change the size of the end product by shifting the discharge opening's spot. Because of this tweakable feature, jaw crushers can adapt to a bunch of different crushing needs. ... (6 to 12 inches) to reduce the size of large rocks. Grinding down to these smaller sizes makes it easier to ...

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...

Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock. As the distance between the two plates decreases continuous size reduction takes place. ... Figure 5.1 is a typical sketch of a large gyratory crusher used as a primary crusher to reduce ...

The difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or …
