Energy-saving ball mills meet the requirements of different materials for impact force, based on years of design and production experience. Xingkuang Machinery summarizes the multi-stage ball distribution technology of ball mills. It mainly determines the diameter of steel balls based on the particle size of the material and the distribution characteristics of the material particle size, which is small in the middle and large at both ends. The ratio of grinding steel balls in the ball mill adopts a configuration mode of large in the middle and small at both ends. The unevenness of the ball mill material requires the corresponding selection of steel balls with uneven impact force, so as to meet the requirements of different materials for impact force. This is the starting point of multi-stage ball distribution. During the grinding, the material will change from large to small, and the particle size will also become smaller, and the number will increase. Naturally, the required impact force will not be so large, but the number of impacts will increase.

According to common sense, the change of multi-stage ball distribution and material is just matched. The important parameter in multi-stage ball distribution is the average diameter of the ball. This deficiency of multi-stage ball distribution is very obvious in cement ball mills. If the impact force is too strong when producing slag cement, it will be insufficient when producing pure clinker cement without crushing. During the grinding process, the particle size of the material gradually decreases along the axial direction of the mill, while the distribution of the steel balls in the mill in the axial direction is very irregular. Therefore, the advantage of multi-level ball distribution in adapting to the material changes in the mill cannot be fully utilized. The ball mill is a low-speed and heavy-load equipment with a large load capacity and a large starting torque. Therefore, the ceramic industrial ball mill usually uses an additional starter motor impact start or soft start device to start. The impact on the power grid is large, and the torque required for operation is reduced after the start-up is completed, so there is a lot of room for energy saving.

Xingkuang Machinery talks about the energy-saving ball mill. During the production process, the balls inside the cylinder run and grind, which will produce certain noise and some cylinder vibration.

Xingkuang Machinery explains the specific reasons for the vibration of the energy-saving ball mill during operation as follows.

1. The sliding keys of the high-speed shaft and the medium-speed shaft of the ball mill are worn or worn out, and the small gear connecting bolts on the shaft are loose or broken.

2. The meshing surface has poor contact and uneven force, which causes frequent axial movement of the gear, resulting in tooth breakage or ring breakage and wheel cracks.

3. The wheel center and ring of the large gear of the shaft are loose, the side pressure plate is movable or the pressure plate bolts are loose or broken, and the static balance of the large gear is poor or unbalanced.

4. The tolerance of the shaft hole of the powder ball mill shaft and the gear. If the hole is too large, the shaft and gear are not concentric, or the gear and shaft are loose due to improper assembly.

5. Too large bearing clearance, uneven three-point bearing, severe wear of sliding bearing alloy, wear deviation and partial or complete melting, grinding of rolling element of rolling bearing into grinding surface or wear of fixed frame of rolling element, etc., will also cause vibration of ball mill.

6. Axial movement sometimes occurs after dry powder ball mill stops, and the reducer is prone to vibration when restarting.
