Technical Field

The utility model relates to the field of related products of roller sleeve forming dies, in particular to a roller sleeve forming die for a large coal mill.

Background

Coal mills are machines for breaking up and grinding coal briquettes into coal dust, which are important auxiliary equipment for coal dust furnaces. The coal grinding process is a process in which coal is crushed and its surface area is increased continuously. To increase the new surface area, the binding force between solid molecules must be overcome, and thus energy is consumed. The coal is ground into coal powder in a coal mill mainly by three modes of crushing, smashing and grinding. Wherein the energy consumed by the crushing process is the least. The grinding process is most energy intensive. The grinding roller is an important grinding part in the coal mill, and the grinding roller sleeve is a part for protecting the grinding roller, which is very easy to wear.

However, when the roller sleeve forming die for the coal mill is required to maintain the injection mold, the disassembly process is complex, so that the time spent by workers is required to disassemble the die, the labor intensity of maintenance personnel is increased, the disassembly process is time-consuming and labor-consuming, and the defect is caused.
