Effects of compression and sliding on the wear and

2018-3-15  The high maintenance costs caused by changing the wear parts of the crushing equipment are another motivation for the research of crushing processes. In mineral processing and aggregate production, the process of comminution involves several stages of crushing. For compressive crushing, gyratory, jaw and cone crushers are used in the primary ...

Crushing in Mineral Processing

2021-2-26  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

Prediction Model for Liner Wear Considering the

A generic model to explore the relationship between the parameters of cone crusher and liner wear is provided in this paper. Relative slide and squeezing between material and liner are considered based on the operating conditions, structure parameters, and material properties. The sliding distance of the material under different conditions is discussed.
