Vertical Mills
Vertical mills, also known as vertical roller mills(VRM), are highly efficient grinding machines used for a wide range of materials. They are characterized by their vertical orientation and the use of rollers to crush and grind the material against a rotating grinding table.
Working Principle
The material to be ground is fed onto the center of a rotating grinding table. As the table rotates, centrifugal force pushes the material outwards, where it passes between the grinding rollers and the table. The rollers, which are typically mounted on pivoting arms, apply pressure to the material, crushing and grinding it. Airflow is often used in conjunction with vertical mills to dry the material and convey the fine product upwards to a separator. The separator returns oversized particles back to the grinding zone for further processing.
Applications
Cement Production
Widely used for grinding raw materials (limestone, clay, etc.), cement clinker, and slag, offering high energy efficiency and superior output capacity.
Power Plants
Specialized in grinding coal for combustion in large-scale power plants, ensuring optimal particle size for efficient burning.
Mining
Perfect for grinding various ores and minerals, particularly effective for pre-grinding before ball mills or processing softer ores directly.
Metallurgy
Efficiently grinds raw materials and intermediates in various metallurgical processes, ensuring consistent particle size distribution.
Chemical Industry
Used for grinding various chemicals and raw materials in chemical processing applications, maintaining product quality and consistency.
Industrial Minerals
Specialized in processing industrial minerals like gypsum, barite, and phosphate rock, delivering precise particle size control and high efficiency.
