Crushing screening operation stage classification and process
Crushing screening operation stage classification and process. In the process of crushing, to a large size of ore, a broken to the required fineness is impossible, must be conducted piecewise.
Concentrator, generally USES two or three stage crushing. According to different crushing product granularity is roughly divided into:
1, the feed granularity is 1500-500 mm, to 400-400 - mm;
2, feed particle size is 400-125 mm, broken by 100-50 mm;
3, feed particle size is 100-50 mm, broken to 25-5 mm.
Each after a broken ore particle size has a certain degree of narrow, before breaking the largest size of ore and the ratio of the maximum particle size of ore after crushing, called broken ratio.
Broken ratio is said after a broken multiples, shrink the ore granularity is one of the important indicators of crusher work.
By crushing assignments and screening effect of ore crushing process called broken screen flow. It is usually composed of two or three stage crushing assignments and to match the paragraphs and broken homework of screening homework in advance.
