Rotary Dryer
Rotary Dryer And Rotary Drum Dryer Machine
Working principle
The wet materials are sent to the hopper by a belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipe of the feeding machine of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of materials to facilitate materials to flow into the dryer smoothly. The dryer cylinder is a rotating cylinder which is slightly inclined with the horizontal line. Materials are fed in through the higher end, and heat carrier enters through the lower end contacting with materials in counter-flow. Sometimes the heat carrier and materials flow into the cylinder together. As the cylinder rotates, the materials move to the lower end due to gravity. When the wet materials move forward in the barrel, they receive the heat from the heat carrier directly or indirectly, and the wet materials dry. Then, the wet materials are sent out through the discharge end through a belt conveyor or screw conveyor. The inner wall of the barrel is equipped with a lifting flight, which can lift the materials and scatter them, increases the contact surface of the materials and the airflow, in order to improve the drying rate and forward the materials advancement.

Advantages
1.Wide application. A wide variety of staff like coal, oil, natural gas etc, dry mass, granule and powder material can be applicable to this machine.
2.Easy to transport and install. Simple design, self-insulation. The internal adopts assembled structure that improves the accuracy of the equipment.
3.Good granulation effect. We have arranged the second granulation zone reasonably regarding the characteristics of diverse fertilizers.
4.Low using costs. It adopts an assembled hoist board to fully exchange heat and reduce the energy consumption. High heat efficiency can reach 70-80%.
5. Good Performance and high efficient productivity. There are temperature induction monitor, uniform vibration and air proof setting devices. Short drying period is normally between 10 to 300 seconds.
Application
Rotary dryer is generally suitable for granular materials and also be used for drying sticky paste material or higher water content materials. It is commonly used in drying sand, slag, slime, chicken manure, cow dung and etc in chemical industry, metallurgy, building materials, mining and other industries.
Delivery
If customers need, we will send a professional engineer to their site for installation, commissioning and staff training after customers buy the equipment. We will offer 1 year long warranty time since the machine goes to work. Customers satisfaction is our ultimate pursuit.
