what is limestone


Limestone bases on Calcium Carbonate (CaCO3). Lime and limestone is widely applied as construction material and industrial material. Limestone can be processed into building stones or be baked into quick lime, and then add water to make slaked lime. The lime slurry and lime putty can be used as coating material and adhesive. Lime is also the majority material for glass industry. Combined with clay, after high temperature roasted, lime can be used to produce cement.

ModelLarge Scale Raymond Mill, Vertical Mill

Stage 1: Crushing of raw materials

The bulk material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).

Stage 2: Grinding

The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.

Stage 3:Classification

Through classification, the coarse powder will return to main mill to grind again.

Stage 4:Collection of finished products

The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
