RFQM series air mill RFQM SERIES FLUIDIZED-BED JET MILL

 RFQM series air mill is Yingkou Ruifeng Powder equipment Co., Ltd. According to years of rich experience, aerodynamics, hydrodynamics and other data, and combined with the actual production of various problems, The improved model is practical, and widely used in fine processing of talc, calcite and other non-metallic mineral powder. The fineness of the finished powder is between 1 μ m and 30 μ m.

 Working principle

 Fluidized bed airflow Grinder (hereafter referred to as Air Mill) is a kind of equipment which uses high speed air flow to realize dry material crushing. It consists of grinding bodies, nozzles, classifiers, etc. The material enters the grinding area through the inlet of the material, the compressed air is injected into the grinding body at high speed through the supersonic nozzle, and the coarse particles are speeded up in the supersonic jet flow. And smashing at the junction of the nozzle. When the comminuted material enters the classification area with the updraft, under the action of the classifier, the coarse particle material larger than the classifying diameter returns to the grinding body and continues to impact and comminute. The dust collection system consists of dust collector. After the super-fine powder enters the dust collector through the sealing pipe, the packing is finished product by the discharge system. The dust enters the dust collector, filters the gas after the cloth bag (the German Bedafur filter bag), pulls out under the action of the induced fan, the tail gas is discharged into the atmosphere. The amount of dust emitted is lower than the dust emission standard set by the national environmental protection department.

Performance advantage 

1. The classifier adopts new technology. The specially designed classifier is more than 30% lower than the original classifier, which reduces the energy consumption of the fan 20-30, and concentrates the particle size distribution, thus avoiding the grinding of the powder in the machine. Compared with the old type of air mill, energy saving 20, 30, the output is higher than 30, 40. 

2. The new structure has higher strength, higher speed, longer service life, more convenient lubrication and maintenance, and is driven by Honeywell or SIEMENS high energy efficiency motor. All aspects go beyond the direct connection of the motor.

 3. The system uses touch screen interface to operate, PLC program automatic control, classifier, main fan, feed machine are all controlled by Igawa inverter, feed system can be more quickly based on system pressure difference, current and other data. Accurate feed. In order to ensure the stable and efficient operation of the whole system, the ash cleaning control of the pulse dust collector and the speed control of the main fan are carried out automatically according to the pressure and pressure difference of the system. 

4. Wear is small. Because the main comminution action is the impact and collision between the materials, the high speed material particles rarely collide with the grinding body wall, so it can be used to comminute the materials with Mohlich hardness above nine grades.

 5. Flammable and explosive materials can be comminuted by inert gas. 

6. No pollution. Because the material is driven by the airflow, it does not bring into the medium, so the material will not be polluted in the process of crushing. 

7. Yield: 50kW 5000 kg/h; fineness: d97m 3N 45 μ m;

The machine is widely used in talc, brucite, barite, magnesium hydroxide, lithium iron phosphate and other non-metallic minerals, electronic materials, chemical, new materials, abrasive, refractory, rare earth, ceramics, metal powder, toner, pesticide, etc. medicine
