Brief Introduction
Roll bearing ball mill 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 mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
Main features of the roll bearing ball mill
According to the way of materials and discharging, ball mill can be divided into dry type ball mill and wet type ball mill.
Ball mill is mainly made up of feeding part, discharging part, rotary part and driving part, including reducer, small drive gear, electrical machine and electronic control. The hollow shaft adopts steel casting, and its inner lining is detachable and changeable while the rotary rack wheel uses casting gear hobbing and there is a wear-resisting lining board inside the cylinder with good abrasion performance. This machine is featured with stable operation and reliable performance.
1) to grind various of mine materials and other materials;
2) two ways of grinding: Dry-type grinding and wet-type grinding;
3) good wear resistance with wear-resistance liner plates;
4) reducing energy cost by 30%, with double rows of aligning spherical roller bearing;
5) high-grade steel welding, reliable work condition;
6) fine grinding, capacity rising by 15-20% compared with traditional ball mill;
7) finished particle size depends on hardness of materials and the time of ball mill runs;
