Due to the higher hardness of pebbles, the silicon content is higher. Therefore, the crushing process of cobblestone should be designed reasonably, and the production cost of the production line must be considered while considering the investment cost of the crushing project. In the crushing operation where the raw material is cobblestone, the loss of wear-resistant parts such as jaw plate, blow hammer and impact plate is very high.
We generally recommend jaw crusher or cone crusher to crush it. The main reason for this is that the two types of equipment use the working principle of lamination crushing, which is more ideal for crushing high-hardness materials. Especially compared with impact crusher and hammer crusher, it is obvious that wear-resistant parts are more suitable for crushing and have a long service time, so they are more suitable for cobblestone crushing.
The stone material falls directly into the high-speed rotating turntable from the upper part of the machine; under the action of high-speed centrifugal force, it collides with another part of the flying stone around the turntable in an umbrella-shaped manner to produce high-speed collision and high-density crushing. The eddy current movement is formed between the turntable and the casing, which causes multiple blows, frictions, and crushing, and is discharged straight from the lower part. A closed circuit is formed for multiple cycles, and the required particle size is controlled by the screening equipment. http://www.drobilkainc.com/en
