Jaw Crusher Explained
Size Reduction) A crusher is a machine designed to reduce the size of large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the product via conveyors etc. Crushing is the first of many stages that lead to separation of the mineral(s) from the waste (gangue) material.Waste material can be discarded or recycled allowing …
