How to improve the production efficiency of limestone？

PUDONG, China - Nov. 16, 2020 - PRLog -- In the quarry, the main crushing equipment used is impact crusher, which mainly provides cement production with mixed crushing. It refers to the production process in which two kinds of raw materials are sent to one impact crusher according to a certain proportion in cement production. The common mixed crushing includes limestone and marlstone, limestone and shale, limestone and clay, etc. The mixed crushing of limestone and clay is the crushing of two raw materials with very large physical properties, especially when mixed with high plasticity and high moisture.

The success of mixed crushing can reduce or even avoid the stripping of limestone topsoil and make full use of ore resources. Two kinds of raw materials are processed at the same time, which reduces the construction and operation costs of a set of processing system. The cement mixing crushing process ensures that the discharge particle size meets the requirements of grinding, prevents the crusher cavity from blocking, and ensures the smooth operation of the whole system. Therefore, the whole system from the silo should be specially designed, including the shape and structure of the silo, the chopping of the mud before crushing, the special treatment of the internal part of the body and even the funnel, chute, etc. the impact crusher is used for the mixed crushing of cement production, which has achieved good social and economic benefits.

The impact crusher (https://m.sbmchina.com/products/pf.html) is very suitable for crushing all kinds of soft and medium hard ores for coarse crushing, medium crushing and fine crushing. It can replace limestone and produce cement by processing slag, coal gangue and fly ash with jaw crusher, impact crusher and trapezoidal mill. A new technology of geopolymer cement with clay high alumina material and industrial waste residue (such as slag, fly ash, coal gangue) as the main raw materials, adding 5% special additives, the firing temperature is only 700 ℃, and the energy consumption is only 1 / 2 of ordinary cement. This cement does not need limestone, and the fuel consumption is small, which can reduce 50% of coal combustion, so the dust and waste gas are greatly reduced 50% of the material is waste.
