Large-scale fluidized bed ultrasonic powder grinder, including air compressor, air purification system, ultrasonic current grinder, cyclone separator, dust scrubber, fan, etc. Small and medium-sized fluid bed grinders are usually composed of shredders. Ultrasonic, waterfall transformer, etc., etc., it saves a lot of space and is easy to install, transport and use.

Fragmentation Principle

The ultra-high-speed crusher includes a material storehouse, a screw feeder, a feeding chamber, a crushing chamber, a cyclone separator and a dust scrubber.

First, the material that needs to burst is transported from the cargo hold to the feeding chamber through the spiral feeding device, and falls into the fracture chamber due to gravity.

The shredding chamber is surrounded by specially designed high-pressure nozzles. This is the opposite of a public article. The favorite motto to purify the dry compressed air emerging from the nozzles to form ocean currents collides in the center of the high-speed air stream and then immediately crushed. .

The broken particles are taken to the air flow classification chamber, the qualified particles are taken into the cyclone separator to obtain the required products, and the exhaust gas is released into the scrubber.

Due to the effect of the separator, the larger particles fall into the fragmentation chamber again and decompose again until a qualified product is produced.

Traffic classification

Composition and operation of fluidized bed filter shredder

In order to obtain a few micrometers or even more of fine flour in the ultrafine shredding process, it is impossible to use standard sieving. Therefore, the machine has a turbine classification system in the classification room, which is a typical centrifugal force field structure.

In the effect of a progressive horizontal turbine cascade, if it is on the edge of rotation, the particles may be affected by the forces of two different centrifugal force fields: the F-type centrifugal inertia and the air resistance generated by the rotation of the turbine.

Assuming that the particle size is D, the delta density, the average density is old, the cutting speed of the UT particle, the average radius of the R turbine, the viscosity of the gray medium and the particle runoff velocity are both 2. The force can be expressed in the following equation:

R=3 feet

When the particles are large, the centrifugal force is greater than the endurance, that is, when F>R, the large particles are cut along the turbine to the wall of the substation, and then return to the fragmentation chamber to fragment.
