Ball mill is suitable for grinding all kinds of ores and other materials

Posted by Admin on May 18, 2012

Ball mills is the material to be broken, and then to smash the key equipment. It is widely used in cement, silicate products; new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries of all kinds of ores and other grind-able materials can be dry or wet grinding. According to different ways of discharge can be divided into two kinds of lattice type and Overflow.

How ball mill works

Cylindrical ball mill is a horizontal rotating device, outer gear, the two positions, lattice-type ball mills. Material from the feed device into the compound by the air shaft into the mill screw evenly the first warehouse, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. To coarse grinding of materials in the first position, after single-layer diaphragm plate into the second position, the positions are lined with flat lining, the steel ball, the material to further grinding. Powder discharged through the discharge grate plate to complete the grinding operation.

The steps in detail when problems happen in running the ball mill

When the ball mills is running, there is regular beating noisy. The temperature of ball mill and reducer are high even more than the prescribed number, Reducing the fever of the ball mill. When ball mill reducer is driving, there will be a huge vibration. When the ball mill reducer is running, the sounds were unusual.

For the common problems in operation, in order to resolve these issues better we should according to different reasons to adopt different solutions.

Match of ball diameter is very important: pay attention to the size of ball diameter, which can improve efficiency. Increasing current is increasing speed.

Change the formula is to increase the strength and weight of the ball (to increase its inertia).Grinding time and efficiency have no relationship, because efficiency itself is the ratio of effort and time.

Methods of increasing speed include the use of inverters, modified deceleration device (if there is deceleration device).

Then there is a must to add water while milling time, cause the amount of water that has a great impact to the mill efficiency. Also, dispersant can be added to improve the milling efficiency.

The lubrication system of ball mill

Ball mill main bearing, the pinion bearings used in bearing grease, oil pump through a pipeline to oil in the grease nozzle is sprayed onto the bearing by timing supplement bearing grease to keep good lubrication bearing. Ball mill pinion shaft bearing in the factory has been in the bearing seat is filled with enough lubricant grease, each time you start the ball mill check carefully before bearing lubricating grease filling.

Ball mill gear ring and pinion adopts automatic spray lubrication, pneumatic pump through a pipeline in the oil tank lubricating grease by the nozzle timing is uniformly sprayed to ball mill gear ring and pinion gear surface, keep good lubrication. Spray systems require users to provide instrument compressed air spray system, equipped with oil pressure detection switch, a nozzle detection switch and other instruments to ensure the stable operation of the lubrication system of ball mill.
