Due to the expansion of the workshop, material supply difficulties such as clay, pulverized coal, Workshop labor constraints are also more difficult conditions, it was decided to make homemade grinder, grinding clay powder, pulverized coal, crumble tile powder. Soil crusher, whether in the city or village, in the crushing of clay powder, pulverized coal, cylinder
