Lab Spiral Jet Mill MQP-Lab

Compressed air or superheated steam or other inert atmosphere enters the gas distribution pipe from the feed gas injection port. Under the action of its own pressure, the gas passes through several nozzles arranged tangentially around the seat ring to generate high-speed jets and collides with the materials entering the grinding chamber. The feeding injector composed of hopper, feeding nozzle and Venturi tube is used as the feeding device. The material in the hopper is ejected to the Venturi tube by the jet stream from the feeding nozzle. In the Venturi tube, the material and the air flow are mixed and pressurized and enter the crushing chamber. The crushed material is brought to the center group tube by the air flow and passes through The stack pipes go axially into the center exhaust pipe up or down into the collection unit.

  • The airtightness of the equipment is good, no dust, and the loss of samples is low.
  • Especially suitable for research and development and testing of new products in scientific research institutes, college laboratories, factory research institutes, and factory laboratories.

Working Principle

Compressed gas is used to pass the feeder ejector to bring the ground raw materials into the grinding chamber, and driven by the high-speed airflow from multiple nozzles, it is sprayed on the grinding wall in a tangential manner to achieve the effect of friction grinding. By adjusting the longitudinal depth of the grinding chamber, adjusting the grinding pressure or feeding speed, the fineness of grinding can be controlled. Compared with the Spiral Jet Mill, the controllability of the pulverization fineness is less.

Product parameters

Model Feeding Size(mm) Particle size(D97:μm) Production Capacity(kg/h) Air consumption(m³/min) Air pressure(Mpa) Installed power (kw)
MQP01 < 2 8~150 - 1 0.7~0.85 7.5

Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above is only for selection reference.
