Single /Multiple Classifying Wheel
for Silica Powder (Ultrafine Quartz Powder)
Horizontal Fluidized Bed Jet Mill
Horizontal installation of high-precision grading rotor, linear speed up to 80m/s, to ensure the accuracy of vertex cutting.
Features:
Fine powder with good repeatability, stable and reliable; constant temperature or low temperature without medium crushing; It has the advantages of high energy utilization rate, wear resistance of equipment, closed crushing, clean and environmental protection, and program control system, which is convenient for adjustment and operation.
Application:
Widely used in chemical, minerals, metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health products, high-tech materials and other industries.
Working Principle and Equipment type features
Jet Mill, cyclone, bag filter and fan constitute a complete milling system. After the compressed air is filtered and dried, it is sprayed into the milling cavity at high speed through Laval nozzles. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be milled. The milled materials rise with the suction of the fan. The air flow moves to the classification area, the coarse and fine powder are separated under strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles that meet the particle size requirements are through classifier wheel and collected by cyclone and bag filter; the coarse powder drop to the milling area and continue to be milled.
Single Classifying Wheel
- Particle size range D50:2-45μm;
- Good particle shape and narrow particle size distribution;
- The rotor speed can be adjusted by frequency conversion, particle size distribution can be adjusted flexibly;
- Vertical single-rotor structure can realize large production capacity, high efficiency and low investment;
- Secondary air inlet design, high energy utilization rate, facilitate material flow and improve powder selection efficiency;
- The entire line is sealed, with less dust, low noise, production process is clean and environmentally friendly;
- The control system adopts PLC program control, which is easy to operate.
Multiple Classifying Wheel
- The particle size range of D50:1-25μm;
- Multi stage rotors installed horizontally can achieve higher output than single rotor;
- Each grading rotor is equipped with a speed sensor, and the rotor speed can be adjusted by frequency conversion to flexibly adjust the particle size distribution;
- It is easy to realize large-scale and large capacity. Take talc as an example, D50:≤3μm, and the capacity can reach 57t/h;
- The whole system is closed comminution, less dust, low noise, clean and environment-friendly production process;
- The control system adopts program control, which is easy to operate.
