Crushing of lime in the production of lime-silica binder at operating plants of silicate bricks

The issue of own production of lump lime and the correct location of technological equipment, in particular crushers, at existing production facilities at silicate plants is considered. Lime crushing before or after storage has an impact on its safety, unreasonable energy costs and deterioration of transportation conditions and its cost. Production of lime-silica binder requires preparation of lime and fine crushing. Comparative characteristics of crushers of different types according to the final result and the consumed power are given. New crushing capabilities and their impact on the operation of the ball mill can improve the quality of grinding and productivity of mills. Replacement of crushers requires both replacement of unsuitable ones in this case and disc feeders of feed hoppers of the grinding section, which old factories are equipped. The technological schemes of the lime storage and binder production with the arrangement of crushing and grinding equipment are presented.
