In recent years, with the rapid development of the infrastructure industry, the demand for sand and gravel is also increasing. Many investors have entered the sand and gravel production industry. For newcomers, the equipment configuration of the stone production line has to be understood. For different stone processing in different regions, the process flow and crushing equipment configuration of several commonly used stone crushing production lines are as follows: raw materials → feeding → primary breaking → middle crushing → screening → finished products.
The raw materials are fed to the primary crushing equipment at a uniform speed and a fixed amount through the vibrating feeder. After the primary crushing equipment is processed, the raw materials are processed into tens of centimeters, and then the crushed raw materials are sent to the second crushing stage by the belt conveyor. Fine crushing in progress, and then conveyed to the vibrating screen by the belt conveyor for sieving, the stones that meet the customer's production specifications are sent to the finished product pile, and the stones with oversized particles are re-shipped back to the second crushing stage for reprocessing until the particle size meets the requirements, and the stone processing is completed.
For the processing of hard stones such as cobblestone, quartz stone, granite, basalt, etc., the equipment of the crushed stone production line is: vibrating feeder, jaw crusher, cone crusher (fine jaw crusher), vibrating screen.
For the processing of medium hardness stones such as limestone, calcite, feldspar, etc., the equipment of the crushed stone production line is: vibrating feeder, jaw crusher, impact crusher, vibrating screen.
For the relatively brittle stone materials such as coal gangue and coal, and want to simplify the process flow, the crushed stone production line is equipped with: vibrating feeder, hammer crusher, vibrating screen.
