Project Description

FL Multiple-stage Classifier in Series

widely used in chemical industry, minerals (especially suitable for non-mineral materials classifying, such as calcium carbonate, kaolin, quartz, talc, mica), metallurgy, abrasives, ceramics, refractory materials, medicines, pesticides, food, health products, new materials, etc. industry.

  • Can be used in series with multiple classifiers to obtain one or more narrow-size products at one time
  • Compact structure, small occupation, lower investment cost.
  • Suitable for classifying materials such as abrasives, soldering tin, foaming agent and carbon powder into particle size in narrow distribution.
  • Suitable for precise classifying of dry micron material.
  • The air screen type secondary air design has high energy utilization rate, promote material flow and dispersing, improves material flow the efficiency of powder selection.
  • Classifying efficiency (extraction ratio) can be 60%~90%.
  • System equipped with muffler operating under negative pressure, meet environmental requirements,noise <76dB(A).
  • The inner lining is made of alumina, no metal pollution, meeting the requirements of high purity materials.
  • Grinding is completed in closed system, little dust, low noise in a clean and environmentally friendly process.
  • PLC control system, easy operation.
  • In conjunction with ball mill, table roller mill and Raymond mill to form closed circulation.
  • The motor can be connected with a belt, which is stable and reliable, realizes high speed and increases the speed, and breaks through the problem that the well-known motor brand does not have a high-speed motor.
  • Optional explosion-proof design, can also be upgraded to a nitrogen circulation system to meet the processing needs of flammable and explosive oxide materials.

Working Principle

The classifier and cyclone separator, dust collector and induced draft fan form a classifying system.
Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, the coarse particles entrained part of the fine particles collided with the wall and the velocity disappeared, descending along the cylinder wall to the secondary air outlet, and the coarse and fine particles were separated by the strong washing action of the secondary air. The fine particles rise to the classification zone for secondary classifying, and the coarse particles are lowered to the discharge port for discharging.
