Tips to maximize crushing efficiency Pit & Quarry : Pit

May 13, 2019· Jaw crushers are routinely choke fed, as this maximizes production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, breaking up flaky or slabby particles. If you seek fewer fines, trickle feeding material into the jaw crusher could achieve this.

Crusher Wikipedia

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.

Comminution Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
