11.20 Lightweight Aggregate Manufacturing

2015-9-10  The production of lightweight aggregate begins with mining or quarrying the raw material. The material is crushed with cone crushers, jaw crushers, hammermills, or pugmills and is screened for size. Oversized material is returned to the crushers, and the material that passes through the screens is transferred to hoppers.

Sand and Gravel Aggregate Process Plant,

2 天前  Aggregate is a widely used building material in modern engineering. In general, the aggregate is divided into coarse aggregates and fine aggregates. Specifically, the fine aggregates with a particle size below 5mm are also called sand. The particle size above 5mm is called coarse aggregate, which is often called stone. Camelway has years of experience in producing sand and gravel aggregate ...
