· A mining crusher is a machine used to reduce large rocks into smaller pieces. Crushers are designed to handle a range of materials. It is from ores to coal and various minerals used in the mining industry. There are several types of crushers commonly used in mining operations: Jaw Crusher. Gyratory Crusher.

· A gyratory crusher is a type of crusher that uses a mantle to guide the crushing process. The mantle is suspended on an eccentrically rotating shaft, which causes the mantle to gyrate. The gyratory crusher has a higher capacity than a jaw crusher. It is often used for primary crushing in the stone crushing industry.

· To prolong the lifespan of your jaw plates, consider implementing a rotation strategy. When wear becomes evident, a double turn is recommended. · First Turn: Rotate jaw plates when wear reaches around 50% on their lower regions. · Second Turn: Initiate the second turn when wear approaches 90% in the same areas.

4.4 Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.

The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments.

· There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact.

· Stone crusher machines work by using pressure to crush the rocks and stones. The machine’s motor powers the belt and pulley to move the jaw up and down through an eccentric shaft. When the jaw moves towards the fixed jaw, the stones are crushed, and when the jaw moves away, the crushed stones fall out of the machine.
