Limestone Mill

limestone grinding mill is a kind of new high-tech milling machine. This mill is used for grinding coarse limestone, the finished product size can be adjusted discretionarily from 80-325 meshes and finished product size of some materials can reach up to 600 meshes. also widely use for like limestone, dolomite, quartz, calcium carbonate, feldspar, cement, clay, marble, calcite, clinker, barite, gypsum , Non-Metalic ore etc.

Application of Limestone Powder

Construction field: Limestone powder can be formulated into lime mortar or cement-lime mixed mortar for masonry or plastering works.


Chemical industry: used to manufacture fertilizers, plastics, rubber, dyes, pesticides, and soil conditioners


Desulfurizer and denitrification agent: used for flue gas treatment in coal-fired power plants and industrial boilers. Through the desulfurization and denitrification treatment of limestone powder, the content of sulfur oxides and nitrogen oxides in the flue gas can be effectively reduced, and the pollution to the atmosphere can be reduced.

Product Features

High grinding efficiency and convenient fineness adjustment

It has the advantages of continuous production, large production capacity, high grinding efficiency, vertical cage separator head, uniform fineness of finished products, easy to adjust fineness and small energy loss.

Strong adaptability

Strong adaptability to materials, can grind a variety of Mohs hardness is not greater than 7 non-metallic ores.

Green environment protection

Pulse dust collection system, strong dust cleaning effect, all the positive pressure parts of the main engine are sealed, basically realize no dust processing workshop.

Fewer transmission parts, low maintenance costs

The equipment has compact structure, less transmission parts, low maintenance cost, stable operation and easy installation.

Working Principle

limestone grinding mill workflow

1.After big block be crushed into small particle by the jaw crusher.

2.Fall into the silo through the bucket elevator,The electric magnetic vibrating feeder under silo evenly feed the material into the Raymond mill to grinding according to the set quantity of flow.

3.When the main machine of the Raymond mill is working, the grinding roller rolls tightly on the grinding ring under the action of centrifugal force. The material is scooped up by the shovel and sent to the middle of the grinding roller and the grinding ring. The material is broken into powder under the action of the grinding force. Then, under the action of the fan, the powdered materials are blown up and passed through the analyzer. The materials that meet the fineness requirements pass through the analyzer. The materials that do not meet the requirements are returned to the grinding chamber to continue grinding.

4.The qualified material go into the double cylone powder collector with the airflow,then transport to the discharge hole by the discharge screw, the excess air suction into pulse dust collectorby the negative pressure fan and discharge after reach the standard of the dust remove .

5.The finnal products transport to the cylinder silo by Pneumatic transmission device.
