The influence of the raw material grinding fineness on the brick industry products quality

摘要

The brick industry development trends have two main directions: high product quality and use of lower quality clays and secondary (recycled) raw materials. The development trends reflect today's market requirements-high-quality materials at low prices. The product quality is approaching that of face bricks, sintered and semisintered products. In this situation, it is important to devote more attention to addressing the problem of raw material (domestic, harmful impurities, secondary). Wet preparations reach their limits at a grain size not less than 0, 5 mm.
