The ultrafine Vertical Roller Mill made by AMCL Machinery Minimum are based totally on specialized knowhow from Nihon Cement Co. Ltd. Japan. These units are used for substantial electrical electric power conserving and capacity enhancement all through the industry of Clinker and Rawmeal Grinding. Now we now have close to twenty years of expertise in source and installations of Vertical Pre Grinding. We have now offered 30 Installations in India & Middle East.

Vertical Roller Mill Principle of Operation

Clinker or Limestone is fed through a central chute in the VRM where centrifugal force, combined with the rotation of the table, distributes product close to the table surface. The table and rollers then grind the material, which is then extracted from the VRM by gravity and a little help from a scrapper. A grinding force is transmitted to a set of three rollers at 120 Degree apart through a hydraulic system.

We are offering our Mill System for up gradation and optimization of existing Cement plants and Raw Grinding Systems

The VRM can be used in

Pre Grinding Mode
Hybrid Mode
Finish Mode
Constructional Feature
Rollers:
Roller type is produced from special alloy steel castings and are confirming to Nihon Cement Specification AT-C for wear resistance. Spherical shape of roller increases its life. Roller Shaft manufactured out of special alloy steel duly hardened tempered and ground. Roller shafts are clamped to the journal head which are hinged to the spindle. Grinding Force is presented by hydraulic cylinder transmitted to Roller Through Spindle

Grinding Table:
The grinding table manufactured out of high grade cast steel is directly mounted on gear box output Flange. The upper surface of the table is fitted with table liner segments constructed of special wear resistant cast steel and held in place with retainer ring. The table liner is divided into segments for ease of handling. A scrapping paddle is indatlled below the table and the paddle is driven by rotation of the table.
