Limestone belongs to easily broken materials, with low hardness and low silicon content. Therefore, the production cost of limestone plant as raw material is much lower. Therefore, for the limestone crushing production line, we can directly use jaw crushing plus counterattack crushing scheme, which can not only obtain good stone grain shape, but also have a long service life for the wear parts of the crusher. Usually, it takes one or two years for a pair of jaw plates to be normal.
Another factor we need to consider is that due to the relative fragility of limestone, the use of counter-breaking for fragmentation will produce more powder. This is due to the characteristics of impact breaking. If the customer's market does not require the size of the stone, two-stage jaw breaking can be used to reduce the proportion of powder, but also relatively reduce some investment costs. The specific process can be determined according to the actual situation of customers.
Because limestone is easy to crush, cement factories using limestone as raw material usually use composite crusher to crush single machine. The limestone can be broken directly by a composite crusher, and the particle size after crushing can reach less than 10-20 mm. Such a crushing method is to crush limestone to the smallest possible size, without considering the particle size problem.
