Calcium carbonate is a common inorganic compound commonly known as limestone, limestone, stone powder, etc., and is found in rocks such as vermiculite, calcite, chalk, limestone, marble, and travertine. Calcium carbonate can be classified into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystalline calcium carbonate depending on the production method. Heavy calcium carbonate (heavy calcium) is obtained by directly pulverizing natural limestone, calcite, etc. by a mechanical method (Raymond mill or the like). Light calcium carbonate (light calcium) is obtained by calcining limestone at high temperature, water digestion, carbonization of carbon dioxide, and finally dehydration, drying and pulverization.
Stage 1: Crushing
Raw calcium carbonate is crushed to 15–50 mm to fit the mill feed size.
Stage 2: Grinding
Crushed material is sent to the mill via elevator and vibrating feeder.
LM vertical mill & MTW European mill: for standard fine powder
LUM ultra-fine vertical mill: for ultra-fine powder
Stage 3: Classification
Ground powder is classified. Off-spec material returns for regrinding.
Stage 4: Powder Collection
Qualified fine powder is collected by the dust collector, then delivered to the silo for bulk or bag packaging.
To cater to specific material characteristics and meet customer requirements, SBM provides a range of grinding mills, including the MTM, MTW, LM, LUM, and SCM series.
To ensure environmentally friendly production, various measures are implemented, including the adoption of dust removers and sealing at each component.
SBM's solutions are highly automated, characterized by the utilization of a centralized control platform. This allows for the monitoring and effective control of the entire production process, resulting in significant savings in labor costs.
For each customer, a dedicated engineer is assigned to oversee their project, ensuring prompt resolution of any questions or issues that may arise. Additionally, our 24/7 online service is readily available to provide assistance at any time.
