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.
Since 1976 we have repeatedly been able to supply Yamama Cement Company with our mobile crushing plants For the new site Yamama Cement Co has opted for the economical concept of fully mobile crushing plants from thyssenkrupp Polysius again to supply the two 10 000 tpd production lines
