Product Description
What Are Overflow Ball Mills?
Ball mill is the key equipment for grinding materials to get the product after the crush process, and it is widely used in many manufacture industries, such as cement, silicate, refractory material, ferrous metal, nonferrous metal, nonferrous mining, chemical and building material industries.
As per material discharging mode, there are three types of ball mill: wet grid ball mill, dry grid ball mill & overflow ball mill.
Working Principle of the Overflow Ball Mill
An Overflow 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.
Overflow ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recalculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.
This formula calculates the critical speed of any ball mill. Most ball mills operate most efficiently between 65% and 75% of their critical speed.
Structure of Overflow Ball mill:
The machine is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).
The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.
