cement vertical roller mill for clinker production lines

Cement Vertical Roller Mill Overview

Compared with traditional ball mill, cement vertical roller mill can significantly reduce energy consumption, and it has obvious advantages in grinding efficiency, drying capacity, stability of product fineness, etc., so it is widely used in large-scale cement production line.

According to the scale requirements of different projects, we provide a variety of specifications of cement vertical roller mill, which can meet the production requirements of 1,000 tons to 7,000 tons of cement clinker per day.

Working Principle of Cement Vertical Roller Mill

Compact structure, small size, overall closed, more stable operation, and can effectively reduce the emission of dust. The equipment is mainly composed of the following parts:

1. High-efficiency powder separator: The device can efficiently sort the powder and separate the finer powder from the coarse material. The quality of cement products is ensured by precise control of material particle size.
2. Grinding roller device: This is the core component used to crush the material, usually using a combination of conical grinding roller design, can improve the grinding efficiency.
3. Grinding disk device: The grinding disk is fixed on the output shaft of the reducer, which is the contact area of the material in the grinding roller crushing process. The grinding disk crushes and disperses the materials through rotation.
4. Hydraulic loading device: Provide enough pressure for the grinding rollers to ensure that the material is crushed, to ensure that the grinding pressure between the grinding rollers and the grinding disk is stable.
5. Hydraulic lubrication system: Provide lubrication for the moving parts in the equipment, reduce friction and prolong the service life of the equipment.
6. Reducer, motor and electrical system: These components work together to ensure stable operation and efficient operation of the equipment.

Advantages of Cement Vertical Roller Mill

1. Low energy consumption: One of the advantages of cement vertical roller mill is low energy consumption. Its average electricity consumption is only 30 degrees per hour, while traditional ball mills usually require 54.2 degrees per hour. This means that it can produce high quality cement at a much lower cost.
2. High grinding efficiency: Vertical roller mill can realize high efficiency grinding through the cooperation of conical grinding rollers and grinding disc. The material is quickly crushed by compression and shear action, and can quickly reach the required fineness.
3. Excellent drying capacity: The equipment can carry out drying operation at the same time, reducing the energy consumption of the material in the drying process, suitable for processing raw materials with high moisture content.
4. Stable product fineness: Cement vertical roller mill has good adjustability, can adjust the matching of particles according to the production demand, to ensure that the particle size of cement products is uniform, in line with quality standards.
5. Easy to adjust: The operating parameters of the equipment are easy to adjust, can flexibly respond to market demand, quickly switch cement varieties to meet the needs of different customers.
6. Economy: The running cost of the equipment is lower, compared with the ball mill, its power consumption is greatly reduced, the running cost is more economical.
7. Cement strength: The cement strength performance of cement produced by cement vertical roller mill in 3 days and 28 days is comparable with that of traditional ball mill, and it is slightly higher in some indexes, which ensures the stability and quality of the product.
