Introduction
Raw vertical mill is a type of industrial equipment used to crush or grind materials into small particles. It is widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials.
Features
1.High-performance separator and optimised airflow ensure high separation efficiency and low pressure loss for energy saving.
2.Unusually large rollers permit coarse feed and ensure a thick grinding bed for maximum uptime.
3.All impact forces and dynamic reactions are small and therefore easy to accommodate – prevents vertical mill stops.
4.Segmented wear parts for table and rollers use the most wear-resistant materials and hardfacing for long life.
5.Reversible roller segments ensure high material utilisation.
6.External circulation reduce power consumption of fan.
7.Feed sluice ensures air flow and steady feed flow for minimum power consumption and optimum mill production.
8.The vertical raw mill is easily adaptable to grind wet materials.

The concrete mill installed power and technology parameter will be adjusted appropritely basing on the actual material property and requirements of owner;
-
The above specification also applies to limestone powder mill, and the concrete type selection shall be decided according to material property.
