Professional China Raymond Roller - Grinding Roller for Mill – HCM

When the mill works, the material is fed into the machine from the feeding hopper on the side of the machine casing. It relies on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis and rotate itself at the same time. Due to the centrifugal force during rotation, the grinding roller swings outwards and tightly presses on the grinding ring, so that the shovel blade scoops up the material to be sent between the grinding roller and the grinding ring, and the grinding roller achieves the purpose of crushing the material due to the rolling and crushing of the grinding roller. Grinding roller is one of the wearing parts of grinding mill. Generally, the roller must be replaced after the mill has been used for a period of time. This should be determined according to the customer’s raw materials, frequency of use and operation. Taking limestone as an example, if the quality of the grinding roller is not too hard under the same operating conditions, then excessive wear will occur and the service life will be greatly reduced.

Technical advantages

The materials of the rollers are mainly divided into ordinary alloy steel, high-quality alloy carbon steel, ZG65Mn manganese alloy steel, ZGMn13 manganese alloy steel, etc. Among them, ordinary alloy steel and high-quality alloy carbon steel are ordinary materials with general wear resistance, this type of grinding roller can be used to process softer materials. ZG65Mn manganese alloy steel and ZG65Mn manganese alloy steel have superior wear resistance. Alloy steel has strong wear resistance which is mainly used for mining hammer head, lining board, cutting head accessories, it is the optimal choice for processing superhard materials.
