Crushing in Mineral Processing

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones .

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations .

Stationary Sources Aggregate & Rock Crushing Operations

Stationary Sources Aggregate & Rock Crushing Operations

Aggregate and rock crushing operations involve the handling and processing of nonmetallic mineral products for the construction industries. Nonmetallic mineral products are quarried or mined and are then transported to the processing plant for further classification and/or further size reduction.

Dust Control or Prevention for Crushing and Screening

Dust Control or Prevention for Crushing and Screening

Mineral crushing and screening operations can be major sources of airborne dust due to the inherent nature of size reduction and segregation processes. Without adequate solutions, workers' health can be seriously compromised over time. (Relative emission rate ratios of crushing and screening equipment)
