1. Wear resistant and heat-resistant alloy castings are used internally. Long service life, reduced maintenance time, and improved equipment operation rate.

2. The refractory layer inside the dryer cylinder reduces the corrosion and wear of the cylinder, prolongs its service life and has small heat loss.

3. Because the hot air stove degree and the dryer body are sealed statically, it completely solves the problem of large air flow between the traditional dryer and the furnace body. Difficult to seal.

4. Automatic control is adopted for blanking. According to the materials with different moisture and viscosity, the passing time of materials is controlled reasonably to give full play to their drying capacity.

5. The material and hot air flow conduct heat exchange in reverse flow, which is conducive to the full use of heat energy, energy saving and consumption reduction.
