Ball mill

Small Ball Mill for sale

Ball mill is the main grinding machine to grind various mineral ores, coal, cement raw materials with dry process and wet process. There are two kinds of ball mills, grate type and overfall type due to different ways of discharging material, or wet ball mill and dry ball mill according to grinding process.

Ball mill is an efficient tool for grinding materials like rocks, raw-of-mine ores in a tumbling mill with the presence of metallic balls or other media into fine powder. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

Ball mill Application

Ball mill is a key equipment for fine grinding, regrinding etc. Our ball mill can grind crushed ore or other materials that can be grinded either by wet process or by dry process.

Where size control of the final product is important, closed circuit grinding is the most efficient method ofoperation. The production of a higher quality product at a lower cost justifies the additional capital investment.

SBM fine powder ball mill can be used as cement clinker ball mill, coal ball mill, limestone ball mill, iron ore ball mill.

The common minerals can be crushed by Ball mill are:

Granite	Limestone	Basalt	Quartz	river stone
Mica	Feldspar	Calcium Carbonate	Clay	Mica
Bentonite	Cement clinker	Dolomite	Iron ore	Gold ore

Ball mill features

1. The ball mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on.

2. The hollow axis adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears.

3. The barrel body is inlaid with wearable plates.

Ball mill design and ball mill efficiency

This Ball mill is made up of feeding part ,discharging part, gyre part, transmission part(decelerator, small transmission gear, generator, electrical control )and so on .The hollow axis adopts the cast steel and the rotary big gear is processed from cast rolling gear .The barrel body wears well and bears wearable scale board.

And compared with the traditional ball mill, the motor power of the energy-saving ball mill can reduce the power by 18-25%, lubrication of 70% and comprehensive energy-saving of over 20%.And during the normal function, we need not to change the main axis, which can save a lot of maintenance cost and time .And the main bear adopt oil grease, which is convenient to avoid the heavy metal pollution.

ball mill efficiency is based on a work index value developed to directly reflect industrial milling practices. Mill selection is based on this value and related empirical equations. Improved grinding efficiency requires making a change from an energy per ton basis to an efficient particle breakage basis.Recently, investigators concluded that grinding efficiency is limited to less than 20%

Ball Mill operation

The materials will be crushed and mixture by the impact effect of falling grinding body (steel ball and pebble) and grinding effects of the inner surface of the ball mill. And at the same time, the eccentric force produced by the rotating of the barrel will bring the steel ball to a certain height and the grinding body will be brought up first and then down second according to the rotating direction, which will have the heavy bash and grinding effect. And then the materials will receive the continuous crushing.

In operation, we must always pay attention to bearing temperature. The temperature shall not exceed 50 ~ 65℃. We also always pay attention to motors, voltage, current, temperature, sound, etc. And pay attention to lubrication system. The temperature of the oil tank shall not exceed 35 ~ 40 ℃, the pressure to the pipeline should be maintained at 1.5 ~ 2.0 kg / cm2. Check the lubrication of transmission components such as gear, main bearing, grading machine reducer. Constantly pay attention to the change of nature of ore, and to take appropriate measures in a timely manner under the circumstances. When stopping ball mill, First stop the feeder machine, then stop the ball mill machine until the ore has been dealt with. The last is pump. With grading machine screw lifting equipment to raise sand surface, and then stop grading machine.

This ball mill pdf has a better grinding condition and will precede the crushing process in the closed machine with no dust pollution.
