Single-cylinder dryer is a device that drives the material to fully exchange heat with the high-temperature flue gas through the rotating cylinder and the set lifting plate,so that the material is dried,with good drying effect,large production capacity,high operation rate,energy saving and environmental protection,easy operation and maintenance,and long service life of the whole machine.
After years of practice and research and development,our company has adopted a number of patented technologies and unique designs to improve the problems of the original horizontal dryer,that is,the rotary dryer,which is a rotary dryer,with large investment,large floor area,high energy consumption,low thermal efficiency and poor stability,and the problems existing in the original dryer have been improved,which has greatly alleviated and solved these problems,and the technical performance level is in the forefront of similar products in the domestic counterparts.

How it works

The main body of the rotary dryer is a rotary cylinder with a certain inclination, and is also equipped with a fuel chamber, exhaust, dust collection, feeding device, etc. It uses high-temperature flue gas as the drying medium and enters the drying cylinder under the suction of the exhaust device. The wet material enters the dryer barrel by the feeding device and comes into contact with the high-temperature flue gas. The high-temperature flue gas transfers heat to the wet material by convection, radiation and conduction, which is the heat transfer process, after the material is heated, the water evaporates into the dry medium, which is the mass transfer process. At the same time as the heat and mass transfer process, the material is constantly moving due to the continuous rotation of the cylinder, and the material flows from the high end of the cylinder to the low end; In the process of the movement of gas and materials, the materials are dried and discharged out of the machine, and the exhaust gas is discharged to the atmosphere after dust collection.

Performance benefits

1、The appearance is treated with high-strength external thermal insulation materials,which greatly reduces the heat loss.
2、The inner cylinder is treated with high-temperature anti-corrosion paint,which reduces the corrosiveness in the machine.
3、The vortex device is used inside,which improves the thermal efficiency and increases the residence time of the material in the machine.
4、The design of the multi-combination lifting plate makes the material appear a rain-like material curtain on the cross-section,increases the contact surface between material and air,and reduces the wind tunnel phenomenon in the machine.
5、The supply of drying heat can be designed according to the regional resources,such as hot blast stove,boiling furnace,gasifier,natural gas furnace,biomass furnace,etc.,which can effectively reduce production costs.
6、The whole system is automatically controlled by microcomputer,and digital display and tracking are carried out.
7、Low selection,high output,the total investment is 30%less than that of ordinary rotary dryers,which is equivalent to vertical dryers.
8、According to the needs of drying materials and time,a variety of models are available.
