Principle of ice spar drying machine

Hot air from the inlet tube at a suitable spray speed from the bottom of the dryer into the stirring and crushing drying chamber, the material has a strong shear, blowing, rotating, so the material by centrifugation, shearing, collision, friction and by the divisor of the particles, enhanced mass transfer heat. At the bottom of the dryer, the larger and wetter particles are mechanically broken under the action of the agitator, the particles with lower wet content and smaller particle size are increased by the swirling airflow and are further dried during the rising process. Due to the gas-solid two-phase rotation flow, the solid phase inertia is greater than the gas phase, solid gas two phase relative speed, strengthen the two-phase mass transfer heat, so the machine production intensity is high.


Ice Spar Dryer Features

A variety of feeding devices for selection, feeding continuous stability, the process will not create bridging phenomenon.
A special cooling device is arranged at the bottom of the dryer to avoid the deterioration of the material at the bottom high temperature zone.
Special Pneumatic sealing device and bearing cooling device, which effectively extend the service life of the transmission part.
The Special Air separation device reduces the resistance of the equipment and effectively provides the air flow of the dryer.
The drying chamber is equipped with a grading ring and a swirl film, and the material fineness and final moisture can be adjusted. (such as calcium carbonate final moisture can be regulator
to ≤0.1%) relative to other drying methods, can effectively increase the proportion of the material.

The dry indoor circumferential air velocity is high, the material stay time is short, effectively prevent material wall and heat-sensitive material deterioration phenomenon, to achieve efficient, fast, small equipment, large production.
