Aug 08, 2014 Jaw crushers are heavy duty machines designed to efficiently crush hard rocks by using compressive force. They are generally used as primary crushers in majority of crushing processes regardless of the industry. Jaw crusher machines are most commonly categorized depending on the width of the feeding chamber and are divided into large, medium and small.
A jaw crusher is generally used as a primary crusher in a crushing circuit. Product is fed into the top of the jaw crusher by an vibrating grizzly feeder. The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw. Jaw crushers
1.Extrusion crushing equipment, such as jaw crusher, rotary crusher, cone crusher, etc. It is suitable for crushing raw materials with a high abrasion index. The content of stone powder in products is low, but generally, the crushed materials have many needle-like particles and poor pumping performance.
Jaw crushers are widely used in the mining and construction industry due to great efficiency in every crushing tasks. They allow operators to crush the materials to a specific size by adjusting the plates at the bottom and capable of moving around the job site by using their own wheels or being pulled by any towing vehicle. Buying a jaw crusher ...
Jul 30, 2020 Generally, a jaw crusher finishes the crushing process by squeezing the material between stationary and moving jaw plates. The peaks and valleys of the jaw plates are offset from one another and use the mechanical advantage of leverage to break the rock. Without this, the crusher has to rely on energy and friction to crush the rock. ...
