Clay Rotary Drum Dryer
The three-cylinder dryer is an improved energy-saving product based on the single-cylinder rotary dryer. It has been recognized by many industries and has achieved good results. This equipment increases the pre-drying design of the wet material before entering the machine and prolongs the drying time of the wet material in the machine, and installs sealing, heat preservation and reasonable supporting measure. So the efficiency of the dryer's production capacity is greatly improved. The advanced technology, reasonable operating parameters and easy operation, make it widely used in the drying process of sand, slag and other mixed materials from various industries. The material exchanges heat between the inner cylinder and the hot air flow in the form of radiation, convection, and conduction, and the heat exchange in the outer cylinder is combined with conduction and convection. Therefore, the thermal efficiency is high and the energy saving effect is significant. Moreover, the importance is the outlet temperature of this dryer is low, which helps to extend the service life of the tail dust removal system.
Scope of application: iron powder, mineral powder and other mixed materials, dry-mixed mortar, yellow sand in the construction industry, and raw materials in the chemical, foundry and other industries.
In addition, fuel burners, combustion chambers or supporting elevators, belt conveyors, metering feeders, cyclones, pulse dust collectors and spray towers can be designed according to user needs.
1. The dryer is scientific and reasonable, efficient and energy-saving. The material exchanges heat with the hot air flow in the inner cylinder in the form of radiation, convection and conduction, and the heat exchange in the outer cylinder is in the form of conduction and convection. The dryer has high thermal efficiency and significant energy saving effect. After testing, the thermal efficiency greatly exceeds the traditional dryer by about 50%.
2. The machine adopts the downstream drying process of materials and hot air flow, which has a wide range of applications.
3. Compact structure. The whole machine is installed horizontally with supporting wheels. The large and small gear transmission are replaced by the supporting wheel transmission, which makes the equipment installation more convenient, simpler operation, more reliable operation.
4. The external surface area of the machine is more than 30% less than that of the single-cylinder rotary dryer. And the outer cylinder has the effect of heat preservation and heat insulation on the inner cylinder. The surface temperature of the outer cylinder is low, and the heat loss is small, so highly efficient and energy-saving.
5. A variety of lifting plate designs make the exchange of materials and hot flue gas more fully.
6. Use frequency conversion to adjust the speed of the barrel, and use the appropriate speed according to the feed water content and output requirements to ensure that the needs of the next process are met. Moreover, it can set with the automatic temperature monitoring system, for easier operation.
The material enters the inner cylinder from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting plate of the inner cylinder to achieve heat exchange in a spiral manner, and the material moves to the other end of the inner cylinder and drops the middle cylinder for counter-current drying. The material is continuously raised in the middle cylinder, showing a two-step forward and one-step backward moving mode. The material in the middle cylinder not only fully absorbs the heat emitted by the inner tube body, but also absorbs the middle cylinder. It also prolongs the drying time, and the material reaches a dry state here. The material travels to the other end of the middle cylinder and falls into the outer cylinder. The material travels in the outer tube in a rectangular multi-loop manner to achieve the drying effect and quickly discharges out of the dryer under the action of hot airflow. The wet material that does not achieve the drying effect cannot be fast due to its own weight. As it progresses, the materials are fully dried in the rectangular lifting plate, thereby achieving the drying effect and completing the drying process.
1. Before sales, we sales team will know know the real situaiton from our customers, such as the feeding size, crushing capacity, final sizes and the electricity condition,etc. then our technician team will design proposals according the situations, and we will update the solution according to customer's further requirements.
2. After concluding the contract, our engineer technician will prepare the foundation drawing about the equipemnts. at the same time, our production factory will prepare the equipment timely.
3. After delivery, our installation engineer will be ready to guide the installation and commissioning for the equipment, to make sure that each item going smoothly and meet the customer's requirements.
