Ball Mill

Ball mill is cylindrical, lying around the axis air cylinder to rotate, within a stone (porcelain) ball or a steel ball. In the rotation, accompanied by abrasive ball improve, roll in rotation, in the roll down, the ball friction and impact the pigment aggregate separation. Especially the impact, on the sintering aggregates are especially dispersion effect, is the unique performance of ball milling, therefore suitable for difficult "dispersed pigment.

Basic Info

Ball mill use and application:
After the ball mill is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, such as glass ceramics industry production, various ores and other materials may be grinding of dry or wet grinding.

Abrasive viscosity during milling in general not straight too high, too high will stick ball, lose the ball rolled down the friction and impact, should not be too low, low friction between the ball (shear stress) is too small. Is generally believed to Daniell flow point method is suitable as a reference. Ball milling, the apparent filling amount is about half the view volume, abrasive after accession, the feeding amount just to get the ball immersion and "appropriate speed of rotation. The speed is to make the ball can be filed with the simplified rotation, measures with the ball rolled down the slope of piled up. Speed is too slow, it cannot be the ball aloft, and make all the ball along the tube wall to slide down, and the tube wall and the ball wear; speed slow, although the ball will slide down along the wall, however promotion problem, shorten the length of the rolling. The speed is too fast, brush the ball will be raised too high, the ball fell down; instead of roll, this reduces the shear effect, and can make the chipped the ball. If speed is very fast, the ball would follow the turn, there is little shear effect.

The abrasive viscosity, suitable ball charge and loading conditions, ball milling in the rotation of the impact sound can be heard intermittent, rather than the grinding wall sound or silent. The operation and management of milling is relatively simple, and can prevent the volatilization of solvent. But may not be directly input should be pigment, pigment and paint by pre mixed and then put into. Otherwise the ball milling, its mixing efficiency and the results are poor. Do not decrease the milling due efficiency at both ends of the barrel, can avoid the accumulation of raw materials, has a great influence on these raw meal fineness.
