Vertical roller mills (VRM) are a type of mainstream clinker grinding equipment in the cement manufacturing process. Vertical roller mills are still newish cement mills since their history in cement production is no more than 20 years, but they have already become the standard cement equipment in many regions and are getting more and more popular among cement producers.

The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process. In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.

CHAENG vertical roller mills can be used as cement mills, raw mills, and slag mills. CHAENG also supplies vertical roller mill components and parts, we can customize machines according to customers’ needs.

1. High grinding efficiency
2. Low power consumption
3. Low wear rate
4. Small production costs
5. Small coverage area
6. Low noise generation

Vertical Roller Mill Features

• Due to the high air velocity and the heat transfer rate of airflows at the air duct ring, small particles in the material can be dried instantly.
• The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of over-grinding and improve the grinding efficiency.
• The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity.
• Vertical roller mills can be transported in parts and constructed onsite, avoiding difficult logistical issues and associated costs.
• The fineness of product cement can be adjusted easily with the vertical roller mill.
• The parts of the vertical roller mill have low wear rate.
• Vertical roller mills generate less noise than ball mills.
• Vertical roller mills usually have small floor area and building space.
