All of our dryers are custom designed to suit the unique processing needs of your material.
The single cylinder rotary dryer is designed for drying bulk materials in various industries: building materials, metallurgical, chemical, glass, etc. On the basis of heat engineering calculations, we select the most optimal dryer size and design for customer requirements.
The capacity of the drum dryer is from 0.5 tph to 100 tph. According to the calculations, a loading chamber, a burner, an unloading chamber, a mechanism for dust collecting and gas cleaning are manufactured. The dryer adopts automation system and a frequency drive to adjust the temperature and rotation speed. This makes it possible to vary the drying parameters and overall performance within a wide range.
Rotary dryer is suitable to dry metallic and non-metallic mineral, clay in cement industry and coal in coal mine etc. For example, sand, vinasse, slag ,sludge, coal powder, sawdust, limestone powder, rice husk, mineral powder , clay, etc.
The working principle of a rotary dryer is based on gravity and heat exchange.
The wet materials that need to be dried are sent to the feeding hopper by a belt conveyor or a hoist, and then enter the material end through the feeding pipe. The slope of the feeding tube is greater than the natural inclination of the material, so that the material can enter the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined from the horizontal line. The material is added from the higher end, and the heating medium is in contact with the material. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. In the process, the material and the heat carrier exchange heat directly or indirectly, so that the material is dried, and then sent out through a belt conveyor or a screw conveyor.
Gas burners, light oil burners, heavy oilburners, pulverized coal burners, andbiomass pellet burner, etc.
Provide space for fuel combustion, theend of the chamber is provided with anair inlet and an air regulating valve, andthe interior is built with refractory
cement and bricks, and the temperaturein the burning chamber can reach up to1200 C. lts structure is exquisite andreasonable, and it is closely combinedwith the dryer cylinder to providesufficient heat source for the dryer
Given different structures and applications, the rotary drum dryer is divided into several types. And thus, drying technology is more targeted.
According to the structure, rotary dryers are divided into the single-cylinder type and multi-cylinder type.
Based on experience and customer feedback, Zoneding engineers will recommend the single-cylinder rotary dryer. These two types of rotary dryers have almost the same drying efficiency. While the structure of the single-cylinder one is simpler, resulting in more convenient daily maintenance. The maintenance personnel can directly get into the cylinder body for inspection. For multi-cylinder dryers, this is difficult to achieve.
Working site of single-cylinder rotary dryer and multi-cylinder rotary dryer
According to the heat transfer mode, the rotary dryer is divided into the direct type and indirect type, or it can also be divided into a co-current rotary dryer and counter-current rotary dryer.
