Processing Materials: Gold, silver, lead, zinc, copper, molybdenum, iron, manganese, tungsten, cement, ceramics, barite, bauxite, limestone, gypsum, calcium carbonate, coal, graphite, feldspar, potash feldspar, phosphorus ore, fluorite, clay and some other materials.

It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries.

The main component of the ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenously grinding. The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening. Finally, acceptable particles are discharged from the discharge opening. Hollow shaft with the anti-spiral blade returns the steel ball and the coarse ore block.

The characteristics of the grid type ball mill is row ore terminal equipped with mineral grid board, other are similar to the overflow type ball mill. Due to the pulp grinding machine is through the grating ore discharge device, so called grate ball mill.

Grid ball mill is the key equipment for pulverizing materials after crushing. It is widely applied to the industries like cement, silicate product, new building materials, refractory materials, fertilizer, ferrous metal and nonferrous metal ore dressing, and glass ceramics, etc. It can carry our dry or wet pulverizing of various ores and other pulverizable materials.

The electro motor drives the cylinder to rotate through the reduction gears and the peripheral rack wheel reducer transmission, or the low speed synchronous motor directly drives the cylinder to rotate through the peripheral rack wheel reducer transmission. Inside the cylinder, there are proper ore grinding media-steel rod. Under the eccentric force and frictional force, the ore grinding media are lifted to a certain height and fall down in the state of dropping. The materials to be ground continuously go into the cylinder from the ore feeding mouth and are crushed by the moving grinding media, and then are discharged by the overflow and the force of continuous feeding to go to the next procedure.

Ball Mills What Are These Machines and How Do They Work? Short flash video at bottom of page showing batch ball mill grinding in lab. May have to click on browser "Allow Active X blocked content" to play A 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. 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 recirculated 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.
