Selection principle of the ball mill grinding process:


When ore selected dynamics in 55-65% less than 0.074 mm, can consider to:


1, ore reduction to 10 to 15 mm, using a grinding process.


2, when the mill scale is larger, can use the ore crushing to 20 to 25 mm, with the first period of open circuit of two paragraphs grinding process. The process of the first paragraph by rod mill grinding plant.


3, ore crushing 300-350 mm, with the mill and ball mill, half or autogenous grinding mill and ball mill, ball mill and finely process to deal with.


4, when the ore granularity is very thin, less than 0.074 mm grade over 80%, or choose not required phase, can be used for the first period of full closed circuit grinding process two pieces.


5, when the crude ore contains certain amount of precious metals, these precious metals are likely to gather in the grinding circuit, can be used for the first period of the ends of the closed-circuit grinding process.
