Application:

1)Wet grinding including batch mill and continuous ball mill ceramic glaze grinding

2)Dry grinding in synthetic resin and other industry

Dry grinding of ceramic raw material and mineral products

Wet Grinding Instruction(Ceramic industry)

For wet grinding process,when charge of ball is up to 55% of net volume of the mill,the best status can be realized.

The volume of ball within the mill can be estimated with formula:

W=3.14xR2xDxLx25%/1000

Remarks:

W-weight of ball(Kg)

R-radius of mill(cm)

D-bulk density of ball(g/cm3)

L-length of mill(cm)

For glaze grinding-raw material: ball=1:(1.8~2.0)

For body material grinding-raw material: ball=1:(1.0~1.2)

Dry Grinding Instruction

The volume of raw materials=Effect capacity of millx35%

The volume of ball=Effect capacity of millx50%
