One of the main raw materials in cement industry is limestone powder between 200mesh and 325mesh. Through crushing and fine grinding, raw materials (limestone and clay) are made into cement raw meal and calcined into cement clinker after fed into cement kiln.

SBM LM series vertical mill is just designed for limestone grinding. You can choose your trusted motors and electronic elements which can be ABB or SIEMENS. To greatly improve capacity, you can also choose open-circuit grinding system. For detailed customized solutions, you can chat with our free online services.

Raw materials used in cement industry:
Materials: limestone
Fineness Requirement: 200mesh ~ 325mesh
Grinding plant: LM vertical mill

SBM limestone grinding mill (80~325mesh)
SBM offers you LM series Vertical Mill to pulverize your limestone to desired fineness. The vertical mill is kind of large scale powder grinding equipment which can work continuously with higher capacity. You can precisely control your desired fineness. After crushed in LM vertical mill, the limestone powder can be directly used to produce cement.

LM Mill LM series vertical grinding mill is one advanced powder making mill through many years' research & experience and bringing in the latest mechanical techanical techniques of Europe.It is one complete plant which integrated with drying, milling, classifier elevater.

 High capacity -Temperature controllable air contact material to meet different humidity requirement; Low cost -Complete system integrated of crushing, drying, grinding and classification needs less space; Reliable operation -Automatic device and sealed system avoid powder overflow and reduce noise.

Limestone grinding process (200~325mesh)
Limestone materials are feed to the center of the grinding table through the air locking feeder. Hot air comes into the grinding chamber. Materials move to the edge of grinding table from the center, and then are pulverized by the grinding roller until blown up by the airstream. Bigger materials fall down to the grinding table for further grinding. Finer limestone grains in airstream pass the separator on the top of the mill, and are gathered by dust catcher. By contacting the hot airstream, the moisture materials are dried to meet your moisture requirement.
