2020-12-2  What is Sand-gravel Aggregate? Sand-gravel aggregate is a general term for sand, gravel, stone and other materials in construction projects, which is the main building material of concrete and masonry stone in hydraulic engineering. Aggregate, a type of granular loose material, acts as the skeleton or filling in concrete.

2021-5-9  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

Segregation This can occur when material is initially stockpiled during load-out and while being discharged from conveyor head pulleys. “When material is coming off the head pulley, finer rock will settle on the bottom of the belt, and the big rock wants to shoot out farther than the finer rock,” Buchanan said.

Helping reduce segregation can be achieved using conventional stackers by keeping the end of the stacker as low as possible to reduce the distance the aggregate drops. By moving the stacker using this method back and forth to create layers, variation in the process is spread out over the pile thus reducing shipping variation.
