What’s the Relationship Between the Mobile Rock Crusher Machine and Rock Characteristics


The mobile rock crusher machine is a highly integrated rock crushing equipment with automatic walking ability, which integrates receiving, crushing and screening functions with one part. Understanding the basic rock characteristics will greatly facilitate the targeted procurement of equipment and subsequent efficient production and processing. In the processing of sand aggregate, the processing index of small mobile rock crusher machine mainly includes two indexes of crushability and abrasiveness.

The general friability index is used to refer to the impact of the strength of rock and mineral machinery on the crushing. The crushability of the rock affects the discharge particle size of the crushing equipment, so it also affects the matching selection of processing equipment such as the mobile rock crusher machine for sale. According to the professional index, the fragility of rocks can be divided into three levels: medium fragile, hard to break, and very hard to break. According to rock characteristics, limestone used in civil buildings belongs to the medium fragile class; lime greenstone and basalt, which are common in hydropower projects, belong to the fragile class.
