The limestone and clay mixture and adjusting additives sand and iron ore are distributed by conveyors to respective bunkers. After that, dosed raw materials are supplied by conveyors to the crusher md the raw material mill, where the material is crushed to the required fineness and dried.
Feb 07, 2019 Chalk is soft raw material, it does not require crushing. Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness of limestone The more clay substances, the lower its hardness. This is an excellent raw material for cement production.
Normally, the major part of this sludge is used as raw-material in the limestone make up process. Although this waste is partially used as raw-material in the own pulp and paper process, in this specific case, due to limitations of the lime kiln, the limestone make-up does not drain all lime mud generated by the production process.
