VTM Euro-type Grinding Mill

VTM European version grinding mill is a vertical ultrafine grinding equipment, which combines foreign advanced technology and realizes ultrafine grinding of materials through roller grinding principle. The finished product fineness range is 325-3000 mesh, which is suitable for grinding materials such as calcite, talc, kaolin, phosphate rock, etc.

Compared with traditional ball mills or Raymond mills, this equipment integrates the functions of grinding, powder selection and drying, and has the advantages of high efficiency and energy saving, small footprint and convenient operation.

Technical Features

1. High efficiency and energy saving

• Bevel gear integral transmission: reduces energy loss and increases transmission efficiency by more than 20% compared to traditional mills.

• Curved air duct design: reduces air flow resistance, avoids material blockage, and improves powder selection efficiency.

2. Intelligent control

• Frequency conversion speed regulation: The main machine speed and powder selection machine can be adjusted by the frequency converter to achieve flexible control of fineness and output.

• Automation system: centralized electrical control, easy operation and high stability.

3. Durability and easy maintenance

• Thin oil lubrication system: reduces bearing wear and extends equipment life (traditional mills mostly use grease lubrication).

• Modular design: The core components such as grinding rollers and grinding discs are made of wear-resistant materials, which support quick replacement and reduce maintenance costs.

4. Environmental protection and multifunctionality

• Integrated dust removal system: Equipped with pulse bag dust collector, the dust emission concentration is lower than the environmental protection standard.

• Drying function: can process materials with high water content and reduce pre-treatment steps.

5. Wide applicability

• It is suitable for a variety of materials with Mohs hardness ≤ 9, such as quartz, calcite, metallic silicon, etc. The finished products have uniform particle size and high purity.

1. Grinding process: The material (0-15mm) enters the center of the grinding disc through the feeding system, and the grinding roller crushes the material under the pressure of the hydraulic system. The centrifugal force generated by the rotation of the grinding disc causes the material to spread outward, and the particles that do not meet the fineness requirements return to the grinding disc for further grinding.

2. Classification and collection: The fine powder after grinding rises with the air flow to the dynamic powder classifier, and the fineness of the finished product is controlled by adjusting the speed of the powder classifier. The fine powder that meets the requirements is collected by the cyclone powder collector or bag dust collector, and the coarse powder falls back to the grinding disc for re-grinding.

3. Air circulation: The system adopts a closed negative pressure circulation design. Excess airflow is discharged after dust removal and purification to reduce dust pollution. VTM European version grinding mill structure diagram
