Zinc stearate spin flash dryer principle:

XSG system rotary flash dryer is my company digestion and absorption, bold use of foreign advanced technology, combined with the actual situation of domestic drying, self-developed design of utility model patented products.
The hot air enters into the main tower of the flash dryer tangentially from the air inlet at the bottom of the mainframe and forms a spiral rising high-speed whirling airflow in the main tower of the flash dryer. At the same time, the bottom annulus size is adjusted according to different material properties so that the wind speed is at a maximum Good condition. The material directly enters the flash dryer tower via the screw feeder, rapidly dispersing and rotating with high speed airflow under the impact of the high-speed airflow. For larger and wet pellets, high-speed airflow is not enough to crush and rotate at high speed, so gradually falling under the action of gravity, when falling to the bottom of the host by the crushing device at the bottom forcibly broken and micronized, and then with the high-speed airflow Rotate together to complete the drying process. In order to make the final moisture content of the material to a very low while not affected by fluctuations in the initial moisture and affect the quality of products in the drying tower to set multi-layer cyclone to form a more stable fluidized bed, while the cyclone film also serves to ensure drying The necessary residence time and grading effect.

Zinc stearate flash dryer features:
1, the use of dual air duct cut into the wind, to avoid the rotating field in the radial flow velocity non-uniformity.
2, the effective control of the final moisture and fineness, through the cyclone film and into the wind speed to coordinate the unity and control.
3, rotating blade layout unique structure, with small wear and tear, wide contact surface, cutting force and so on.
4, good at handling heat-sensitive materials, the host belongs to the bottom of the high temperature zone, the region has high gas velocity and high cooling water protection device to avoid the possibility of material coking discoloration.
5, system resistance, high thermal efficiency, good operating environment, low labor intensity.
6, the host with a new type of seal structure, the mainframe bearing life cycle extension and the bearing with a water cycle cooling device.

Rotary flash dryer process
Air through the heater is heated to about 140 ℃, into the spin flash dryer. The wet material is fed into the screw feeding mechanism by the conveying device, and the screw feeder can be steplessly adjusted in speed. The material is forced into the main tower after being squeezed, then it is smashed with blades rotating at high speed and different angles, and is also spun at a high speed by the high-temperature airflow impinging on the main tower of the spin-drying dryer and entrained and then the temperature of the air drops rapidly , The material quickly evaporates to complete the drying process. The material is dried with high-speed high-temperature airflow into the pulse bag filter. Air flow from the outside of the filter bag, up to the discharge, in order to prevent the accumulation of filter bag, by the pulse solenoid valve timing, by the upper part of each filter bag input high pressure air flow (0.5 ~ 0.6Mpa), repeatedly recoil the filter bag, in order to achieve the best dust effect.
