Full analysis of the maintenance and working principle of the centrifugal superfine mill

Centrifugal ultra-fine grinding machine is an indispensable equipment in the chemical, metallurgy, cement, coal and other industries. It is also a relatively easy-to-operate mechanical device in the process of use, and it has a small footprint and convenient use. How to maintain the centrifugal ultra-fine mill during the use of the centrifugal ultra-fine mill? This is what we are going to say today. Let's talk about it in detail.

Centrifugal superfine mill maintenance:

In addition to the sliding bearing on the upper end of the main shaft, the other parts of the transmission use rolling bearings, so it must be operated under good lubrication conditions, otherwise the bearing will be damaged and the service life will be shortened. The maintenance method is as follows: the spindle refueling time is once per shift, but it must be noted that when the oil in the oil cup is not lost or the loss is too slow, the oil passage should be cleaned immediately, and then 50# mechanical oil is added. The oil cup position is at the upper end of the main shaft, and the main shaft The base bearing and the roller bearing are filled with grease gun 3# lithium grease once every time. The analyzer bearing is opened and cleaned every six months. Add 3# lithium grease, fan bearing chamber and lithium base. grease.

Centrifugal superfine mill working principle:

After the centrifugal superfine mill crushes the large raw material to the required feed size, the material is transported to the storage bin by the bucket elevator, and then uniformly sent by the electromagnetic vibrating feeder to the grinding chamber of the main machine. Inside, the material entering the grinding chamber is ground between the grinding roller and the grinding ring, and the powder after grinding is brought to the analysis machine by the fan airflow, and the fine powder that meets the fineness requirement enters the large cyclone collector through the pipeline through the airflow. Separate and collect, and then discharge through the unloader to obtain the finished product. The blade system plays a very important role in the working process of the centrifugal superfine mill. The utility model is located at the lower end of the grinding roller, and the material is shoveled and fed into the roller ring between the blade and the grinding roller to form a cushion layer, and the material layer is rotated by the grinding roller to generate an outward pressing force to the material. Milling, thereby achieving the purpose of milling.

The working process of the centrifugal superfine mill main engine is to rotate the central shaft through the transmission device. The upper end of the shaft is connected with the plum blossom frame, and the frame is equipped with a grinding roller device and forms a swinging fulcrum, which not only rotates around the center, but also surrounds the grinding roller. At the same time as the grinding ring revolves, the grinding roller itself rotates due to friction. The lower end of the plum blossom frame is equipped with a blade system, and the position is at the lower end of the grinding roller. During the same process of the blade and the grinding roller, the material is thrown into the grinding roller ring to form a cushion layer, and the material layer is rotated by the grinding roller. The outward centrifugal force (ie, the squeezing force) crushes the material, thereby achieving the purpose of milling.

Centrifugal superfine grinding machine working process:

After the bulk material is crushed to the required particle size by the jaw crusher, the material is sent to the storage hopper by the hoist, and then uniformly fed into the main machine grinding chamber by the vibration feeder continuously for grinding, and the powder after grinding Taken away by the fan airflow. After being classified by the analysis machine, the fine powder conforming to the fineness enters the large cyclone collector through the pipeline, and is separated and collected, and then discharged into the powder tube to be the finished powder. The airflow is then drawn into the blower by the upper return duct of the large cyclone collector. The whole airflow system of the machine is closed and circulating, and it circulates under positive and negative pressure conditions.

In the grinding chamber, because the material to be ground has a certain water content, the heat generated during grinding causes the gas in the grinding chamber to evaporate to change the gas flow rate, and the connection of the pipes of the whole machine is not tight, so that the outside air is sucked in, so that the air volume of the circulating air flow increases. The airflow is balanced by adjusting the residual air duct between the fan and the main engine, and the excess gas is introduced into the small cyclone collector, and the fine powder brought in by the residual gas is collected, and finally the upper exhaust pipe of the small cyclone collector is collected. Discharge into the atmosphere or into the dust collector to purify the exhaust air.

The working process of the centrifugal superfine mill main engine is to rotate the central shaft through the transmission device. The upper end of the shaft is connected with the plum blossom frame, and the frame is equipped with a grinding roller device and forms a swinging fulcrum, which not only rotates around the center, but also surrounds the grinding roller. At the same time as the grinding ring revolves, the grinding roller itself rotates due to friction. The lower end of the plum blossom frame is equipped with a blade system, and the position is at the lower end of the grinding roller. During the same process of the blade and the grinding roller, the material is thrown into the grinding roller ring to form a cushion layer, and the material layer is rotated by the grinding roller. The outward centrifugal force (ie, the squeezing force) crushes the material, thereby achieving the purpose of milling.

The above is the maintenance and working principle of the centrifugal ultra-fine grinding machine. In fact, the quality of the current mechanical equipment is very guaranteed, but if the equipment is not well maintained, the equipment will still be damaged and will be reduced. The service life of the equipment, so after the purchase of the equipment, not only the equipment to work but also to maintain it, in order to increase the service life of the equipment, so that the production efficiency of the equipment increases.
