Ball Mill

ball mill is crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder. ball mill is widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. It has two ways of grinding: dry process and wet process.

In order to make sure the well operation and using of ball mill, we certainly strictly abide by the operation and maintenance procedures.

Before starting the ball mill, check whether the connecting bolt, gears, couplings are tightening. Checking whether the oil of the oil tank and the reducer is in the adequacy, and Whether the lubricating device and instrumentation have problems. Determines the flow of pipeline. Check whether there are ore to prevent the ball mill machine running. Check the ring gear and pinion gear case with or without abnormal noise.

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.

In the working process of Ball Mill, the ground product quality is consistently high irrespective of plant capacity. During start, stop and full or partial-load operation, no contact takes place between the grinding elements to disturb the vibration free running. A flat grinding track – individually guided – adjustable rollers and a roller swing-out device for servicing ensure that the SBM Ball Mill achieves almost 100% availability. The service for the mill is easy to maintain.

In the discharge end of Ball Mill, a slotted full diameter or partial diameter grate with discharge lifter assembly conveys the material to the discharge trunnion opening. The grate serves to retain balls, tramp, and coarse material. A gradient created between the feed opening and the discharge slots eases the flow of material.

Productive grinding systems are the result of the efforts of disciplines ranging from mechanical design and metallurgy of materials to process engineering and instrument application. Desired grinding results are achieved only through careful and skillful attention to detail.

Our engineers can specify or supply computer control systems for the sophisticated circuits. The cost of computer hardware decreases almost daily, making these controls feasible for smaller installations. Automatic operation saves power, grinding media, and liner wear, while increasing capacity. Software can be developed to suit the most complicated circuits and complex ores.

The ball mill is an indispensable part in the beneficiation equipment and plays an important role in the crush technics. The main types of ball mill are: cone energy-saving Ball Mill, grid Ball Mill, tube Ball Mill, roller bearing Ball Mill, etc. ball mills are prevalent in many industries and are a very high wear piece of equipment. They therefore require frequent, specialist maintenance and repair work. SBM Machinery has the expertise and experience to undertake both services.

Ball Mill’s maintenance is a regular work. The quality of maintenance may affect the Ball Mill’s operation rate and life time. Here will introduce how to maintain and repair the ball mills. Set the maintenance frequency and time by each Ball Mill’s operational circumstances, as well as the quick-wear part or the most wearing part–the wear degree of the lining plate. Besides the daily maintenance of the Ball Mill, the minor repair, medium repair, and heavy repair should be done at fixed period. Here, SBM Machinery mainly introduces the maintenance, and examination standard of Ball Mill, offering convenience to the Ball Mill customers for references.

1) The bearing on the processing of the base is in the same horizontal surface, the center spacing tolerances 1 mm, not parallel longitudinal centerline of deviation 0.5 mm, and horizontal deviation of the centerline of 0.5 mm per metre .

2) Watts Block spherical contact angle should to be uniform for each 50 ⅹ not less than 50 mm2, 1-2; hollow shaft contacting with the Vanuatu should be 90 ° -100 ° every square inch should be no less than 2:00, the Journal and bearing clearance on both sides should approximate the same.

3) Ball Mill with the front flange cylinder cover should ensure that the co-ordination of good contacts, and no pads, two different hollow shaft axis of less than 0.8 mm tolerance, when the ring gear in connection with the cylinder assembly correction, the thrust should be solid, Hong positioning pin, the radial Gear swing of not more than 0.5 mm axial swing of not more than 0.84 mm.

4) Mill liner should be installed to their installed Cover, cylinder liner from the population, beginning with the assembly requirements, the screws tight to the uniform, not leaking. There should be no rubber liner with crack, and crevice use the sponge blocked.

5) Pinion gear with the centerline to centerline parallel, per metre deviation should be not more than 0.2 mm,Top Gear gap 1 / 4 modulus, lateral tooth 1.06 —- 1.8 mm gap. Ball Mill tooth surface contact area of should be no less than 50 per cent of long teeth, tooth-40%.

6) Reducer, motor and the transmission drive shaft coupling should maintain high coaxial, different shaft centerline of not more than 0.3 mm, the center tilt is less than 1 / 1000.
