Limestone Grinding Mill

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be processed directly into stone and calcined into quicklime. Lime is divided into quicklime and slaked lime. After blending slaked lime becomes lime mortar, lime paste, etc.

Limestone powder can be generally divided into coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and ultrafine powder deep processing (400 mesh-1250 mesh) and micro powder processing (1250 mesh-3250).Four types.

The first stage: Crushing

Limestone chunks are crushed by crusher to the input fineness of the mill (15mm-50mm).

The second stage: Milling

The small pieces of crushed limestone are transported to the feed bin by the elevator, and then evenly and quantitatively transported by the vibrating feeder into the mill for grinding.

For fine powder processing, use LM Vertical Mill, MTW European Type Grinding Mill and MRN Pendulum Roller Grinding Mill ; For ultrafine powder processing, use LUM Ultrafine Vertical Mill, MW micro powder mill; And for coarse powder processing, use European Coarse Powder Mill, Straight-through Centrifugal Mill.

The third stage: Grading

The material after grinding is classified by the classifier. The unqualified powder is sent back to the mill to be reground by the classifier.

The fourth stage: Collecting

Fine powder complies with the fineness with airflow go through the pipe into the dust collector for separation and collection. The finished powder collected by the delivery device is delivered to the finished product bin, and then packed uniformly with the powder tanker or automatic packing machine.
