Production process flow of limestone aggregate with an hourly output of thousand tons
The production process of limestone aggregate with an hourly output of thousand tons, the production process of limestone production line, the configuration scheme of limestone production line, the limestone or limestone resources are rich, and the grade of raw ore can generally meet the requirements of various industrial departments. Therefore, it is generally only necessary to carry out simple ore washing and do not need to use complex beneficiation processes for purification. The processing of limestone mainly includes crushing, grading and production of quicklime, hydrated lime, precipitated calcium carbonate, ultra-fine (nanometer) calcium carbonate, carbon dioxide, etc. Limestone generally adopts dry crushing process. For metallurgical and road limestone, the ore can be crushed and screened. For the production of fine powder products, ores are directly grinded by Raymond mill after being crushed by jaw crusher, impact crusher or cone crusher. The product fineness is 100-325 meshes. Limestone is one of the more common materials, often used as building materials, and also an important raw material for many industries. Because of its wide distribution, limestone crushing sand making line is more common.
Production process flow of limestone aggregate with an hourly output of 1000 tons: primary crushing and transportation of aggregate -- aggregate soil removal screening and transportation -- secondary crushing and transportation of aggregate -- primary screening and transportation of aggregate -- secondary screening and transportation of aggregate -- storage and transportation of finished aggregate -- powder transportation and bulk -- compressed air station and pipe network -- weighing system -- water supply and processing unit -- electrical automation system -- spare parts and maintenance center.
Primary crushing of limestone aggregate: the large limestone materials are uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. The coarse crushed materials are screened by the vibrating screen and then transported to the impact crusher by the belt conveyor.
Secondary crushing and screening of limestone aggregate: after the coarse crushed materials transported to the counter impact crushing process are subjected to counter impact crushing, the materials subjected to counter impact crushing are screened by circular vibrating screen, and the larger particles are returned to the counter impact crushing process for re crushing; If finer products or shaping are required, the crushed materials shall be sent to the sand machine for further crushing and shaping.
