Cone Crushers (Parts of a Cone Crusher) Explained
Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

The Ultimate Guide to Jaw Crushing Machines: Types
A hydraulic jaw crusher is a type of jaw crusher that uses hydraulic pressure to crush materials. It has a movable jaw that is operated by an eccentric shaft, as well as a fixed jaw that is positioned opposite the movable jaw. The hydraulic system allows the jaw to open and close, providing a wider range of crushing settings.

Feeding the facts: Apron feeder basics
Normally, the optimal speed an apron feeder is 0.05 – 0.40 m/second (10–80 fpm). If the ores are non-abrasive, the speed can increase to above 0.30 m/second because there will be less wear. Higher speeds would hurt an operation. If your speed is too high, you run the risk of accelerated wear of components. Energy efficiency decreases due to ...
