Rotary dryer is widely used in building materials, metallurgy and chemical industry. It is also used to dry slag in cement industry, clay and other materials. The failure frequency is lower because of its simple structure, easy maintenance, low energy consumption and better stability.

The moist material is taken into the tunnel body from the intake end by helical lobes. And then the lifting blade, which has the function of lifting and drying, will lift the material with the help of the rotation of tunnel body. Therefore, tunnel body must be installed with a certain degree of inclination in order to push the material to the lower discharge end. The tunnel body is placed on two jockey pulleys. On the upper jockey pulley, there is a pair of thrust rollers, which is to prevent axial movement of tunnel body while it is rotating. The motor will drive the small gear through speed reducer. The small gear and the big gear on the roller gather in upon each other and work at a uniform speed. The big gear is fixed on the roller, which can make the roller wok.

Working principle

Wet material from the belt conveyor or bucket elevator to the hopper, and then by feeder feeding through the feeding device into the terminal. Drum dryer cylinder into a slightly tilted to the horizontal rotating cylinder. Adding material from the higher end, low-end entry by the heat carrier, and the material into a counter-current contact, but also heat carrier and the material together and flow into the cylinder. With the rotating cylinder, the material runs by gravity to a more bottom end. Wet material in the cylinder body to move forward the process, directly or indirectly heating the heat carrier, the wet material to dry, and then the discharge end by the belt conveyor or screw conveyor sent. Trumble dryer wall of the cylinder body with lifting plate, its role is to copy the material up and planted, so that the surface of the material increases the contact with the air flow to improve drying rate and to promote material progress. Heat-carrier is generally divided into hot air, flue gas. After heat-carrier around cylinder dryer back then, generally require cyclone trap the gas inside the material brought down. For further reduction of dust content in exhaust gas should be handled through the bag filter before discharge.
