Roller Mining Mill

Roller Mining Mill

Roller Mining Mill 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 Roller Mining Mill during the use of the crusher? This is what we have to say. Let’s talk about it in detail.

Roller Mining 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, the main shaft The base bearing and the grinding roller shaft bearing are filled with grease gun 3# lithium-based grease once every time. The analyzer bearing is opened and cleaned once every six months, adding 3# lithium-based grease, and the fan bearing chamber is added with lithium base.

Roller Mining Mill working principle

After the Roller Mining Mill breaks the large raw material into the required feed size, the material is transported to the storage bin by the bucket elevator, and then the electromagnetic vibrating feeder is evenly sent into the grinding chamber of the main machine to enter The material to 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, and is separated. Collected and discharged through the unloader is the finished product. The blade system plays a very important role in the working process of the Roller Mining 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 pad 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 Roller Mining 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. The frame is equipped with a grinding roller device and forms a swinging fulcrum, which not only rotates around the center, but also rotates the grinding roller around the grinding ring. At the same time, 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.
