Crushers are a crucial part of mining industries. They are used to break down large materials into smaller, more manageable sizes, making them easier to transport and process.
Below are some common crushers:
- Jaw Crushers
Jaw crushers are perhaps the most common type of crusher used in mining and quarrying operations. They work by using a pair of jaws that move back and forth to crush large rocks or other materials. Jaw crushers are typically used for primary crushing and can handle large materials up to 80 inches in diameter.
- Cone Crushers
Cone crushers are another commonly used crusher in mining and quarrying operations. They work by compressing materials between a moving cone and a stationary cone. This compression reduces the size of the material, making it easier to transport and process. Secondary or tertiary crushing is the usual application of cone crushers.
- Impact Crushers
Impact crushers are used to break down softer materials such as limestone and gypsum. They work by using a high-speed rotor that turns the material into a high-velocity projectile. This projectile then strikes the material, breaking it down into smaller pieces. Impact crushers are commonly used in the recycling and demolition industries.
- Hammer Crushers
Hammer crushers work by using a series of hammers that rotate around a central shaft. The hammers strike and break down the material, which is then forced through a screen to separate the finer particles. Hammer crushers are commonly used in the mining and construction industries.
- Roll Crushers
Roll crushers work by using a pair of rotating cylinders that crush the material between them. The material is fed into the gap between the cylinders, and as they rotate, the material is compressed and crushed. It is frequent to find roll crushers being utilized in the mining and construction sectors.
- Gyratory Crushers
Gyratory crushers are similar to jaw crushers in that they use a pair of jaws to crush materials. However, the jaws in a gyratory crusher are angled, allowing the material to be crushed and ground between them. Gyratory crushers are typically used for primary crushing and are commonly found in the mining and quarrying industries.
