High Efficiency Vertical Coal Mill Low Power Consumption For Power Plants

Vertical Coal Mill - High Efficiency Low Power Consumption Easy To Use Maintain For Power Plants
Product Introduction:
Introduction to vertical mill products
Vertical mill, also known as roller mill, is widely used in large-scale material grinding and ultra-fine powder processing in industries such as cement chemical, coal, and power. It is an ideal equipment in the grinding industry that integrates crushing, drying, grinding, grading, and conveying. When used for coal powder preparation, it can make the product fineness meet industry standards.
Grinding disc diameter specification: 1000-2400mm
Moisture content of incoming materials: ≤ 5%
Finished product fineness: 3-4 5 μ M (equipped with a multi head ultrafine powder classification system)
Production capacity: 3-40t/h
{Application field}: This grinder is widely used in industries such as chemical, metallurgy, coatings, plastics, rubber, pigments, non-metallic minerals, etc.

Highlighting advantages
1. High grinding efficiency and low power consumption;
2. Low metal consumption per unit product;
3. The process flow is simple, and the functions of material grinding, drying, and powder selection are completed simultaneously;
4. Small footprint, compact layout, lightweight system equipment, and low investment in civil construction.

operational principle
In the process of powder production, the main motor drives the grinding disc to rotate through the reducer, while hot air enters the vertical mill body from the air inlet. The material falls to the center of the grinding disc through the discharge pipe, and the constant speed rotating grinding disc disperses and flattens the raw material outward with the help of centrifugal force, forming a material bed with a fixed thickness. The material is simultaneously crushed by multiple grinding rollers on the grinding disc. Under the continuous driving force of centrifugal force, the material continuously moves towards the outer edge of the grinding disc. When the material leaving the grinding disc encounters hot gas entering the mill through the wind ring and rises, it enters the separator through the middle shell of the mill. During this process, the material undergoes sufficient heat exchange with the hot gas, and the water is quickly evaporated. The powder selection machine controls the particle size of the finished product at the outlet of the roller mill. Particles larger than the specified size are separated and fall back to the grinding disc. Materials that meet the fineness requirements enter the dust collector through the powder selection machine, and the collected finished product is sent to the finished product warehouse.
