After blasting or excavation and hole mining, the bulk raw materials smaller than 910mm are fed to the raw material warehouse by dump truck, and then sent to the jaw crusher for crushing through the rod feeder to obtain semi-finished materials of about 50-180mm .\r\n\r\nThe semi-finished materials in the first stage are conveyed to the cone crusher through the belt conveyor for medium and fine crushing, and the obtained mixed finished aggregate is sent to the subsequent screening workshop for grading and screening.
The materials larger than the user’s needs are returned to the cone crusher for circular crushing through the belt conveyor, and the qualified finished products that meet the customer’s needs are transported to the finished product silo through the belt conveyor.\r\n\r\nWhen it is necessary to produce high-quality sand, the 5-40mm mixed material can be separated from the first screening workshop and transported to the semi-finished product bin of the sand making workshop through a belt conveyor. Then the material is evenly fed to the sand making machine through the vibrating feeder, and the finished product mixture crushed by the sand making machine is transported to the second screening workshop for screening through the belt conveyor, so as to separate the finished products of different particle levels .
