The finesse of the material milled by the ball mill is 0.074mm 0.4mm, only except for the two small ball mills that have a wider range of 0.075 0.89mm. However, the rod mill fine grinding fineness is about 0.833 0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.
Thus, for instance, a ball mill is rather less efficient than a drop weight type of crusher because of the ineffective collisions that take place in the ball mill. Further work on the crushing of quartz showed that more surface was created per unit of energy with single particles than with a collection of particles.
The ball grinding mill machine usually coordinates with other rock crusher machines, like jaw crusher, cone crusher, to reduce the ore particle into fine and superfine size. Ball mills grinding tasks can be done under dry or wet conditions. Get to know more details of rock crushers, ore grinders, contact us!
Ball Mill machine grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the ball mill machine. The larger the diameter is, the slower the rotation is.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
