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.
·Closed circuit ball mills have been operated for cement milling for decades [[7] [8] [9]] Fig 1 shows the process flow of a closed circuit two compartment cement ball mill The closed circuit operation helped to reduce overmilling of particles [10] resulting in lower specific power consumption [11] in comparison with open circuit operation where the ball mill is
