QLM Series Jet Mill
Principle
compressed air is accelerated into supersonic air flow through Laval nozzle, and then it is injected into the crushing area to fluidize the material (the air flow expands to be fluidized bed and floats and boils and collides with each other), so each particle has the same movement state. In the comminution area, the accelerated particles collide with each other at the intersection of nozzles. The crushed materials are transported to the classification area by updraft, and the fine powder meeting the particle size requirements is screened out by the horizontally arranged classification wheel, and the coarse powder failing to meet the particle size requirements is returned to the grinding area for further grinding. Qualified fine powder is collected in the high-efficiency cyclone separator along with the air flow, and the dust containing gas is filtered and purified by the dust collector and then discharged into the atmosphere.

Application:
nonmetal ore, electronic material, chemical industry, new material, abrasive, refractory, rare earth, ceramics, metal powder, toner, pesticide, medicine.
Features:
◇ Particle size distribution concentration: no over crushing Phenomenon & "free from over size"
◇ Stable operation after startup, high yield, qualified products from a small amount of raw materials
◇ Stable operation, high reproducibility( High reproducibility means that it is stable and can keep the same granularity every time) and reliability; military quality, durable;
◇ Fineness: D97: 3-100 μ m; serial production: 2-5000 kg / h
◇ Automatic one key start stop (optional touch screen), automatic program or manual control
◇ Good universality: various soft and hard, light and heavy materials; good particle morphology and no entrainment
◇ The main engine does not need to supplement the external air or absorb the moisture, and the flow field is stable and the quality is uniform
◇ Only need to open the plexiglass observation window of grinding chamber to change the nozzle: convenient and fast
◇ Only the clean compressed gas passes through the nozzle, so the product quality will not be affected if the wear is very light
◇ There is no dead angle of accumulated material at the bottom of the main machine, and the cleaning is complete; the tailing quick discharge device
◇ Motor is directly linked with classifying wheel (simple construction; easy maintenance; stable turn) A special design which prevents materials from penetrating the bearings
◇ Stable operating behavior which guarantees best possible constancy of fineness and fines yield
◇ The QLM series jet mills produce end products with closely particle size distributions and exact topsize limitation.
◇ The QLM series jet mills are extremely low-wear in operation and can be employed for materials with a Moh's hardness up to 9.5.
