Make the Regular Inspection of Ball Mill

<p>The two stage crushing process can be classified into two stage open-circuit crushing and the two stage closed-circuit crushing. The open-circuit crushing is the crushing products don't need to come back this stage crushing work for being crushed again; the closed-circuit crushing is that: after the crushing products are sieved, the products with unqualified particle size (the products on the screen) will come back this stage crushing work to be crushed again.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years.

This process will guarantee the particle size requirements of crushing products and will not influence the ball mill grinding work. The two stage open-circuit crushing process will be used in some gravity dressing plants and the crushing products will be sent to rod mill. The two stage crushing process is only fit for the small scale mines underground and the production capacity is less than 500t per day, for in these plants the needed total reduction rate is not large and the process load of the crusher is not high.</p>
