Limestone is a non-metallic mineral composed mainly of calcium carbonate, and calcite and aragonite are found in nature. Tight limestone has a fine crystal structure, low porosity, and high strength, with a density of about 265 ~ 2.80 g cm with a hardness of 3 on the Mohs scale. Limestone is widely used in plastics, rubber, sealing adhesives, coatings, and papermaking. At the same time, limestone is also widely used in the building materials industry, such as cement, ironmaking, quicklime, glass, etc.
What equipment is commonly used for limestone crushing?
The limestone processing process goes through four stages: coarse crushing, secondary crushing, grinding, and packaging. Each stage has its own special equipment. Jaw crusher is required for the primary crushing stage, impact crusher or cone crusher is required for the secondary crushing stage, and Raymond mill is commonly used for the grinding stage.
What are the advantages of limestone crushing equipment production?
1.Optimize deep cavity crushing, digitally analyze the operation of each component, and use forged blanks to process heavy-duty eccentric shafts, high-manganese steel jaw plates, and high-cast steel moving jaw assemblies, which greatly improves the crushing efficiency.
2.Hydraulic safety devices are reliable, safe and easy to troubleshoot; At the same time, plain bearings can withstand greater shock loads and are more wear-resistant.
3.Compared with other crushers of the same specification, the eccentric shaft bearings are larger and more durable, and their higher load carrying capacity and effective labyrinth seals greatly extend the service life of the bearings.
