AI Technical Summary
The existing ball mill grinding cylinder has a simple structure, making it difficult to effectively grind different components in mixed solid waste according to their varying hardness and toughness. This results in low grinding efficiency, rapid wear of the inner liner, and poor material flow, which affects the quality stability of the composite cementitious materials.
The design employs a segmented liner plate, including a coarse grinding liner plate, a fine grinding liner plate, and a precision grinding liner plate. The coarse grinding liner plate is equipped with a spiral convex truncated pyramid for crushing hard materials, the fine grinding liner plate has a wave crest and trough structure for homogenization, and the precision grinding liner plate has staggered pits to improve grinding uniformity.
It significantly improves grinding efficiency and the quality stability of composite cementitious materials. Through the segmented liner design, it can differentiate the treatment of industrial solid waste with different hardness and properties, thereby improving the overall grinding efficiency and powder uniformity.
