Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries, for dry or wet grinding of various ores and other grinding materials.

1. When the energy-saving ball mill equipment is running, there is a regular beating sound, and the sound is very loud; It may be that part of the liner bolts is not tightened, and the liner hits the grinding barrel as the ball mill rotates. Judge the lining plate according to the sound, find out the loose bolts, and tighten them separately.

2. Heating of ball mill reducer bearing: In addition to checking the temperature rise of ball mill bearing, the exhaust hole of the reducer should be checked to see if it is blocked, and the exhaust hole should be dredged.

3. After the motor with reducer starts, vibration occurs, mainly because: 1. The two-wheel clearance of the coupling is too small, which cannot compensate for the channeling momentum caused by the self-finding magnetic center of the energy-saving ball mill when the motor is started; 2. The alignment method of the coupling is incorrect, resulting in the two shafts being miscentered; 3. The connecting bolts of the coupling are not relatively symmetrically tightened, and the degree of tightening force is different; 4. The outer ring of the bearing is moving; Adjust the gap between the wheels according to the regulations, so that the two axes are concentric; Tighten the coupling bolts of the coupling symmetrically with the same torque. 5. When the rotor is unbalanced, Zhengzhou energy-saving ball mill will pull out the rotor to find another static balance.

Fourth, when the reducer drives the ball mill, a huge vibration occurs, the balance shaft of the ball mill and the reducer, the axis is not in the straight line, and the ball mill is caused by:

1. When the ball mill installs the lining, there is no secondary grouting, or the anchor bolts after the secondary grouting are not fastened, and the grinding cylinder is rotated with a winch, resulting in the displacement of one end of the grinding cylinder, and the two axes are not in a straight line, so that the reducer drives the ball mill and vibrates.

Solution: To readjust, so that the ball mill axis and the reducer axis are on the same plane axis.

2. The large energy-saving ball mill is large in volume and heavy in weight, which makes the foundation sink; Displacement occurs. The ball mill is set up next to the foundation to monitor the settlement point; Observations are made and adjustments are made when a sinking is detected.

5. The sound of the reducer of the ball mill is abnormal: the sound of the normal operation of the reducer should be uniform and stable. If there is a slight knocking sound on the gear, a hoarse friction sound, and there is no obvious change in operation, it is necessary to continue to observe, find out the cause, stop the car for processing, and stop for inspection immediately when the sound is getting louder and louder.

The beneficiation ball mill is a new type of ball mill designed according to a new concept by using special rolling bearings as the supporting structure of the cylinder. It systematically solves the life and alignment problems of heavy-duty rolling bearings used to replace sliding bearings, sealing problems under harsh environmental conditions, and barrel movement caused by long-term operation. Compared with traditional ball mills, ball mills with this technology can match motor power by 18 to 25%, save lubricating oil by 70%, save cooling water by 90%, and save more than 20% of overall energy savings.

How it works:

The energy-saving ball mill is a horizontal cylindrical rotating device, outer edge gear drive, two-bin, lattice type ball mill. The material enters the first bin of the mill uniformly by the feeding device through the feed hollow shaft spiral, which has a stepped lining plate or corrugated lining plate, which is equipped with steel balls of different specifications, and the cylinder rotates to produce centrifugal force to bring the steel balls to a certain height and fall, which has a heavy impact and grinding effect on the materials. After the material reaches coarse grinding in the first bin, it enters the second bin through a single-layer bin plate, which is inlaid with a flat lining plate and a steel ball inside, and the material is further discharged from the grate plate to complete the grinding operation.

Energy-saving ball mill features:

The energy-saving ball mill has changed the original mill structure, so that the machine body and the base frame are integrated, and it can be hoisted on the foundation plane at one time during installation. The main bearing is equipped with double row radial spherical roller bearings, which can reduce energy consumption by 30%.From the original lattice type forced discharge to overflow type control discharge, the grinding particle size can be improved, and the processing capacity can be increased by 15-20%.

The ball mill is the key equipment for crushing the material after it is crushed. Ball mills are widely used in cement, Portland products Gongyi Longtai specializes in manufacturing energy-saving ball mills failed to.
