Overview The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same.
The cement vertical mill is grinding equipment developed on the basis of similar grinding mills, so it has many irreplaceable advantages, such as high grinding efficiency, low power consumption (2030% less power than ball mill), large drying capacity (simultaneously dry and grind materials with moisture up to 10%), the large particle size of grinding materials, simple grinding process, small ...
The raw vertical mill of CHAENG has stable operation, high output and convenient replacement of parts. It has been recognized and purchased by customers in South Asia, Africa and other markets: 1. A 5000t/d cement production line EPC turnkey project in South Africa adopts raw material vertical mill of CHAENG. 2.
Working Principle: The Vertical Mill operates by utilizing a rotating grinding table and rollers. Materials are fed into the mill from the top and ground between the rollers and the grinding table. As the rollers rotate, the material is crushed and ground, resulting in fine powder or granules.
In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energyefficient, ecofriendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.
Product Definition: Vertical Roller Mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cement, and ceramics. It is an energyefficient alternative to a Ball Mill.

The rollers work harmoniously with a highlyefficient separator and feed sluice to consistently and reliably deliver coal meal to your desired fineness and moisture level. A compact coal mill solution for grinding virtually any type of raw coal Our ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal.
However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement.
SOLUTIONS FOR VERTICAL MILLS. Vertical mill rolls and tables can be refurbished either onsite (usually in situ) or at one of our Integra ™ workshops to suit the customer's specific requirements. Repairs are completed using Welding Alloys' own range of cored wires with wear characteristics specially adapted for these applications in mill repairs.
