Jet Mill appropriately adjusted the gap between the hammer coal mill and the screen: the friction on the screen varies with the distance between the material and the screen, and the friction between the hammer and the screen different.
Thereby improving hammer speed and hammer efficiency. However, in the feed production process, there is a need to adjust the gap between different material sieves and hammer screens. The particles in the ball mill and crusher pulverized cavity have changed after grinding, starting working and working for a period of time. When grinding parts, the gap between the hammer and the increase in the change in the hammer and the production screen will be reduced, and it is difficult to maintain.
Of course, in order to require a production test of some crusher, on the material, under the sie, determine the appropriate hammer and sieve distance, regardless of the screen of the screen and hammer How life can achieve high pulverization efficiency in a short period of time.
After the fluidized bed pulverizer compresses, after filtration, after drying, the fluidized ultrasonic air flow is introduced through the nozzle, so that the material is fluidized, and the accelerated material is integrated in several nozzles. The collision, friction, and cut the microcarriers of the particles.
After the pulverized material is conveyed into the impeller grading area, under the action of the graded wheel effort and fan effort, the coarse powder is separated, and the coarse powder returns to the crushing chamber according to its own gravity, and the qualified fine powder is Airflow enters the cyclone, fine dust is collected by the bag dust collector, and the purified gas is discharged from the air. Air flow milling is compressed by the Raval nozzle accelerates the supersonic gas stream, and the injection zone is brought into the pulverization region to cause the material to be fluidized (the airflow expansion is suspended, and therefore, each particle has the same motion state). .
However, higher grinding efficiency can be obtained in feed production. Technical work experience is two things, for a variety of specific measurements and mill itself. People and labor have extensive experience and use high-cost operations. After the hammer head is worn, the gap between the hammer and the sieve is increased, the friction is reduced, and the crushing efficiency is lowered.
