Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slagand coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint act
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.

Vertical cement mill has high grinding efficiency and low power consumption (20% – 30% less than ball mill). The granularity of the feeding material is larger (VRM cement mill is 80mm-120mm, cement ball mill is less than or equal to 30mm). Cement vertical mill occupies less space and saves 30% of construction cost.
The cement vertical roller mill is one of the most important cement equipment. It is the key grinding machine of materials being crushed. The cement grinding mill plays a vital role in cement production line and cement production process.
GRMK vertical cement mill has the advantages of compact structure and small volume. It mainly includes high efficiency separator, grinding rollers, grinding table, hydraulic loading device of grinding roller, hydraulic lubrication system, reducer, motor, and electrical components. 1.
The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
In a vertical roller mill, materials to be ground fall upon the center of a rotating grinding table. Centrifugal force causes the materials to spread out evenly towards the edge of the plate. As particles lying flatly on the plate reach a certain thickness, they are ground or crushed by multiple pairs of rollers.
