CSM-VD Air Classifying Mill

Widely used in battery materials, non-metallic minerals (Mohs hardness>5), chemicals, inorganic salts, pharmaceuticals, food, pigments, dyes, pesticides, minerals, refractories, new materials and other industries.

  • Available D50:2～45μm.
  • Classifying wheel is Vertical installation .
  • Two-In-One shaft of grinding disc and classifier wheel, compact structure.
  • Especially suitable for ultra-fine grinding in pharmaceutical, food and chemical industries.
  • Small occupation. No dead angle, easy disassembling and cleaning.
  • Lower installation power, wide application, high cost-performance.
  • Different types of grinding disc (pin, hammer, teeth or others) are used based on characteristics of materials to obtain different grinding forces and improve grinding efficiency.
  • Key parts like the hammer, gear ring and classifying wheel are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final product.
  • Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
  • PLC control system, easy operation.
  • Low noise design.
  • The motor can be connected with a belt to increase the speed and break through the problem of high-speed motors without the well-known motor brand.
  • Can be used in series with multi-stage classifiers to produce products with multiple sizes at one time.
  • Optional explosion-proof design, meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials.
  • High-temperature, low-temperature, normal-temperature, airtight cycle, Inert gas cycle designs are available, for different grinding requirements of different materials.

Working Principle

The material is evenly fed into the grinding chamber by the feeding system, strongly impacted by the high-speed rotating grinding disc. At the same time, it is subjected to centrifugal force and collides with the grinding ring gear, and is subjected to various comprehensive forces such as shearing, friction and collision to finished grinding. The grinded material moves to the classifying zone with the airflow. The classifier is adjusted by frequency conversion, separates the coarse and fine materials, the product that meet the fineness requirement enters the cyclone collector and the dust collector with the airflow, and the coarse powders return to the classifying zone, secondary grinding.
