Product Description
A rotary dryer is a robust, continuously operating industrial drying machine designed to reduce moisture content in bulk granular, powdery, or lumpy materials. Featuring a slightly inclined rotating cylindrical drum with internal lifting flights, it maximizes hot air/material contact for uniform, high-efficiency drying. Ideal for mining, chemical, agricultural, construction, and biomass industries, our rotary dryers ensure reliable performance with minimal downtime.
Feature
1. High Capacity & Continuous Operation: Handles 1–100 tons/hour; supports 24/7 processing with low labor input.
2. Energy-Efficient Design: Advanced insulation + heat recovery system cuts energy use by 20–30% vs. conventional dryers; multi-angle lifter plates boost heat transfer efficiency.
3. Durable Construction: Heavy-duty carbon steel/SS304/SS316 build resists abrasion and corrosion; precision bearings and gearbox ensure long-term stability.
4. Precise & Safe Control: PLC automation monitors temperature/humidity in real time, maintaining moisture accuracy within ±0.5%; multiple safety interlocks prevent overload or overheating.
5. Customizable & Versatile: Direct/indirect heating options (gas, diesel, steam, electric); adjustable drum size, speed, and inclination for specific materials.
Working principle
The dry wet material is transported to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the dryer. The cylinder of a sleeve dryer is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, forming a countercurrent contact with the material. There are also heat carriers and materials flowing together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material in the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry and then be sent out through a belt conveyor or screw conveyor at the discharge end. There is a board installed on the inner wall of the cylinder, which is used to pick up and scatter the material, increasing the contact surface between the material and the airflow, in order to increase the drying rate and promote the material to move forward. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through a rotary drum dryer, a cyclone dust collector is generally required to capture the materials carried in the gas. If it is necessary to further reduce the dust content of exhaust gas, it should also be discharged after passing through a bag filter or wet dust collector.
