Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
The test steps are as follows 1 in the test process the confining pressure was firstly loaded to the corresponding confining pressure state using a loading rate of MPa/s and the
