Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. How much reduction each crushing stage is capable of infliction of rocks (reduction ratio) is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed as the move towards and away from each other.

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.

Crushed stone makes projects long-lasting and successful. The Definition. Crushed stone is defined as construction aggregate. A suitable rock formation is mined, then the rock is broken down into various sizes with a crusher. Gravel differs from crushed stone due to the natural process of erosion and weathering, and the rounded shape.

But in hard rock quarries, where the aggregate is crushed, it is simply ‘concrete aggregate’. . Aggregate normally is graded over a range of sizes, ie. 20mm to 14mm as one product, then 14mm to 8mm as another product. . Common products are: GR40-20 – Graded Rounds from 40mm to 20mm. CA14-8 – Concrete Aggregate from 14mm to 8mm.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The gap opening of the primary’s mantle is very important not only to the production of the primary but also to the next stage of size reduction. As the ore becomes smaller it becomes harder to crush. This is because there aren’t the same amount of fracture lines in small rock as there are in large rock.
