2.Features

1, Dual duct tangential inlet, to avoid the rotating field in the radial velocity of the flow field inhomogeneity.

2, Effectively control the final moisture and fineness, controlled by a unified and coordinated swirl sheet inlet velocity.

3, The rotary blade arrangement unique structure, with little wear and tear, wide contact surface, cutting power and other characteristics.

4, Good at handling heat-sensitive materials, the bottom of the host belongs to the high temperature zone in the region of high gas velocity and high cooling water protection device to prevent the material coking discoloration possible.

5, The system resistance, high thermal efficiency, good operating environment, low labor intensity.

6, The host structure with a new seal, the host bearing life cycle extension and circulating cooling water spacer device with a bearing housing.


Spin flash dryer Process

After the air heater is heated to ~ 230 ℃, entering spin flash dryer . Wet material from the delivery device into a screw feeder mechanism, variable speed screw feeder. After the extruded material is forced into the main tower, but then was crushed high-speed rotating blades have different angles, and at high speed into the spin flash dryer high-temperature air Pylons impact high-speed rotation, entrainment rise , then the rapid decline in the temperature of the airflow, the material rapid evaporation of water to complete the drying process. The material was dried with hot air into the high-speed pulse bag filter. Air from the outside into the bag, discharge up to prevent bag product material by pulsed electromagnetic valve timing input turns the upper portion of the bag by the high pressure air (0.5 ~ 0.6Mpa), repeated recoil bag for optimum dust effect.

4.Working Principle

XSG system spin flash dryer is the company digested and absorbed, bold use of advanced foreign technology, combined with the actual situation of domestic drying, self-development and design of utility model patents.

Hot air from the bottom of the main air inlet to cut into the flash dryer Pylons, in flash dryer main tower form a spiral of rising air current speed rotation, while according to materials with different properties to adjust the size of the bottom of the annulus, so that wind speed in the best suitable condition. Material through the screw feeder directly into the flash drying column in the high-speed airflow impact and lead, and with the rapid dispersion of airflow high speed rotary motion. For larger groups and moist particles, high-speed air flow is not sufficient to make it broken and high-speed rotation, then gradually fall under gravity, fall to the bottom when the host is provided at the bottom of the crushing device forcibly broken up and atomized, and then with the high-speed airflow rises together with the rotary complete the drying process. In order to achieve a very low final moisture material moisture while volatility from the beginning to affect the quality of products, set up a multi-layer sheet cyclone in the drying tower to form a more stable fluidized bed, but also play a cyclone sheet guarantee dried residence time and the role of classification necessary.
