Boron carbide (B 4 C) 300 – 500 μm. 2 - 5. Corundum (Al 2 O3) 300 – 50 0μm. 2 - 5. Coated tablets in a stainless steel grinding bowl, grinding balls and quartz sand. These abrasive materials keep slightly sticky sample material longer mobile and ensure therefore a corresponding larger final fineness due to higher "abrasive properties".
Reasons and solutions for the coarse particle size of the ...
The main reason for the excessively coarse particle size of the ball mill: the "roughness" of the ball mill refers to the abnormal phenomenon that the fineness of the mill product is significantly coarser and difficult to control. It generally appears in the double-chamber open-circuit tube mill with a relatively small length and diameter.
