Grinding mill for limestone treatment
Main processing equipment: MTW European Type Trapezium Mill; LM Vertical Mill; TGM Super Pressure Trapezium Mill.
As the major building material, limestone is the main raw material for the production of cement. After ultra-fine grinding, high quality limestone is widely used in the manufacture of paper, rubber, paint, medicine, cosmetics, food, sealing, gluing, polishing, etc.
In generally, there are three types of limestone powder. Coarse limestone powder (0-3mm), fine limestone powder (20mesh-400mesh), superfine limestone powder (400mesh-1250mesh), and ultra-fine limestone powder (1250mesh-3250mesh).
The first step: crushing
By the crusher, the raw materials are crushed in a fineness input size(15mm-50mm) that can enter the mill.
The second step: grinding mill
The crushed limestone are conveyed to the silo by the elevator, then by the vibratory feeder regularly feeds the materials into the grinding wheel for grinding.
The superfine powder processing generally uses LUM series Vertical superfine roller mill, MW ultra-fine mill series.
The third step: recycling
The crushed limestones are classified by the separator, unqualified powders that return the grinding wheel for re-grinding.
The fourth step: collecting the powder
Qualified powders enter the dust collector through the pipeline with the flow of air for separation and collection. The collected finished powder is conveyed to the silo of the finished powder by the conveyor and then for packaging.
