Rotary Tube Drying Machine

The rotary tube drying machine is a rotating metal plate rolling wheel cylinder with steel plate welding. The air cylinder is equipped with a tire. Supported by a drum in the bearing device of a tire roller. On both sides of the wheel is equipped with a pair of loading gear indicator and cylinder limit for running along the inclined direction. The cylinder is driven by an electric motor, and the gear box is driven by a gear mechanism. The cylinder has a certain tilt and rotation. The dryer is slightly sloping, which makes the discharge end of the material feeding end, so that the material is lower under the gravity action by the dryer.

Introduce of rotary tube drying machine

Material to be dried enters the dryer, and as the rotary dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. tube drying machine is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc.The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency.

Working Principle of rotary tube drying machine

The wet and dry materials are transported to the hopper from the belt conveyor or bucket elevator, and then feed through the feed inlet. The natural inclination of the asphalt material is larger than the material, so the material flows into the dryer. The drying cylinder is slightly inclined to the horizontal rotating cylinder. Material from the high-end to join, heating medium into the bottom, into the counter current contact material, but also the heating medium and materials together, flow into the cylinder. Due to the rotation of the roller the gravity of the material runs to an end in the end. In the cylinder body of the wet material forward process, directly or indirectly, the wet material of the heat carrier heating dry, and then by the belt or screw conveyor. On the contact surface of the cylinder, the copy board is installed, and the material is copied to the upper and lower, so that the material and air flow can be increased, and the drying rate can be improved. Heat carrier is generally divided into hot air, flue gas. The heat carriers in the cyclone usually need to be trapped inside the material. To further reduce the amount of dust in the tail gas, but also through the bag filter, wet dust collector, and then put the discharge.
