The domestic manufacturers of spin flash dryer are also more, in recent years the speed of technological progress, enterprises have dominated the market but the product must be updated, the use of more extensive, the market is relatively large.
Glyphosate spin flash dryer operation steps are as follows:

Preparatory work: First check the two flash dryer fan (induced draft fan and blower), hand rotation with or without abnormalities, if abnormal, should be reported immediately repair. Turn hand stirring should be able to rotate, and open the warehouse door inspection, do not block the material, into the air flow smooth, all normal is the next step. If you open the warehouse door to find the mixing chamber blocking material, should be cleaned and keep the wind channel open for further work.
Power on: First of all, open the flash dryer fan, due to the larger motor power to take the star, the triangle switch to start, a long time, so pay attention to the ammeter instructions, when the current drop before the next step can be used, or because the bus current is too large And will have trouble. Then start the blower, open when the current drop after mixing, feeding, off fans and other equipment.

Feed: First open the compressed air valve and open the pulse power switch, open the steam valve, control the inlet temperature to the appropriate range, then open the inverter start button, open the variable frequency feeder, then continue to feed into the hopper to be roasted Material can be. In the drying process should always pay attention to the inlet and the mixing chamber temperature indication, inlet temperature and the pressure in the steam pipe network, should be adjusted in the appropriate range. The temperature of the mixing chamber is related to the wetting and drying of the material and the feeding speed, etc., and the feeding speed should also be adjusted frequently to keep the mixing chamber temperature within the specified range. In the drying process, should always pay attention to off the fan outlet material should be normal, if the material stops, the use of wood hammer hit material to fall, if not material, it should be shut down, turn off the fan will be expected to smash under.
Shutdown: After the drying material should be closed to feed, turn off the steam blowing machine for about 10 minutes, blowing the net excess material, and the temperature in the machine before stopping, stop the flash dryer in reverse order by the boot Can be done. Shut down the material in the trap should be cleaned before leaving.

Rotary flash dryer main features:
1, a variety of feeding device for the choice of continuous feed stability, the process will not bridge the phenomenon.
2, the bottom of the dryer set up a special cooling device to avoid the material in the bottom of the high temperature zone produce deterioration.
3, a special pressure seal and bearing cooling device, effectively extending the life of the transmission part.
4, a special air distribution device, reducing equipment resistance, and effectively provide the dryer air volume.
5, drying chamber equipped with grading ring and swirl pieces, material fineness and final moisture adjustable. (Such as calcium carbonate final moisture regulator can be ≤ 0.1%)
6, relative to other drying methods, can effectively increase the proportion of materials.
7, Drying chamber high circumferential velocity, material residence time is short, effectively prevent material sticky barriers and heat-sensitive material deterioration phenomenon, to achieve efficient, fast, small equipment, large production.
8, the hot air from the inlet pipe at a suitable spout speed from the bottom of the dryer into the mixing crushing drying chamber, the material has a strong shear, blowing, rotating role, so the material by centrifugal, shear, collision, friction and the division Granulation, enhanced mass and heat transfer. At the bottom of the drier, the larger and more wet granulation is mechanically crushed by the agitator. The lower the moisture content, the smaller granularity is entrained by the rotating airstream and further dried during ascent. Due to the gas-solid two-phase rotation flow, the solid phase inertia is greater than the gas phase, solid gas relative speed between the two phases is larger, to strengthen the two-phase mass and heat transfer, so the machine high production intensity.
