When the ball mill bearings are designed, the hydraulic bearing is highly developed. The static pressure bearing is before the mill starts, and the high pressure oil is in the bottom of the bottom of the bearing, forcing the shaft to float in the bearing, thereby forming a intact lubricating oil film at the shaft and the bearing contact surface to ensure the shaft in any speed and load. In the case of a fully liquid lubrication, the operation continues to maintain high pressure oil.
The moving static pressure mixing bearing is a high-pressure oil, moving, and static pressure system simultaneously on the original pressure bearing to solve the launch problem of the mill. After the mill is started, the ball mill is turned off, and the high-pressure oil can also be cut to operate in the dynamic state. Therefore, the hydraulic bearing has the advantages of large load capacity, small starting torque, less wear, high operating precision, has gradually been promoted in the grinder. Sliding bearings with rolling bearing have been successfully applied, and the advantage is that the stress is small in size, the hollow shaft, end cap and the cylinder is small, and the automatic dry oil lubrication system can be used. The ball bearing is also automatically calm, and its power consumption It can reduce 6% and the maintenance costs are also greatly reduced.
What improvements should I do if the ball mill saves electricity?
1. Increase the length of the cylinder and improve the production of powder mill and the stage. Cement is improved, and the output of the ball mill will decrease, and the length of the cylinder is a very effective way.
2. Adopt new wear resistant equipment to improve the degree of fine mill. The powder grunge is used to allow the material to fully agitate the graded material. A new method for controlling the discharge is taken to make the entry and exit zone difference. The new grinding barrel is shortened, the two warehouse is long, the slate is screened, and the large particle size material is fully pulverized in a warehouse.
The mining ore first crushed by the jaw crusher, and passed through the hoist, and the vibration feeder was evenly sent into the ball mill, and the murrup was pulverized and grinded by the ball mill.
The mine fabric of the ball mill is grounded to the next step: classification. The spiral classifier is different from the principle of the deposit in the liquid in the liquid, and the spiral grading machine is different from the principle of the precipitation of the liquid, and the ore mixture is cleaned and classified.
The mineral particles are sent to flotation machines, and different drugs are added according to different mineral properties, so that the desired minerals are separated from other substances.
