The scraper is set on the stirring teeth of the flash dryer

When the material is crushed by the stirring teeth, it is thrown to the wall of the machine and sticks to the wall. If it is not scraped off in time, it will vibrate the equipment in severe cases, and even cause the agitator to block and stop turning. The scraper is set on the stirring tooth of the flash dryer, which can peel off the material stuck on the wall of the machine in time to avoid sticking to the wall. The rotation of the stirring shaft is controlled by a stepless speed regulation motor.

Choose different speeds according to the product particle size requirements, the faster the stirring shaft rotates, the smaller the product particle size. The rotation speed of the screw conveyor of the flash dryer feeder is controlled by an inorganic speed-regulating motor. Control the feeding speed according to the material properties and drying process parameters.

A classifier is set on the upper part of the flash dryer.

By changing the hole diameter of the classifier and the height of the classification section, and then changing the air flow rate, the size and quantity of the particles leaving the dryer can be controlled, and finally the water content and the residence time of the material in the drying section can be controlled. The bottom of the flash dryer is equipped with an inverted cone structure, so that the drying gas flow section gradually expands from bottom to top. The bottom airflow is relatively large, and the upper airflow is relatively small, so as to ensure that the large particles in the lower The small particles are also in a fluidized state, and make the hot air rotate along the vertebral body, increase the wind speed at the bottom, reduce the length of the cantilever part of the stirring shaft, and increase the safety and reliability of the operation; the bearing can be placed outside the machine to effectively prevent the bearing from being in the air. Work in the high temperature zone, thus prolonging the service life of the bearing.

The flash dryer has a compact structure and a small footprint. It integrates drying, crushing and grading. It is an organic combination of swirl technology, fluidization technology, spray technology and convection technology. After drying, it does not need to be crushed or sieved. The production process is simplified, and power and equipment costs are saved.
