Suitable for industries such as chemical, mining, metallurgy, etc., such as ore, slag, coal, metal powder, clay, diatomaceous earth, kaolin, etc

It is widely used in alfalfa grass drying, alcohol lees drying, straw drying, sawdust drying, marigold drying, shaving drying, ginkgo leaf drying, Chinese herbal medicine drying, brewer's grains drying, Baijiu lees drying, potato starch residue drying, cassava residue drying, barley malt drying, melon seed drying, bagasse drying, hawthorn drying, rapeseed cake drying, vegetable drying, etc. The thermal efficiency is up to 80%, significantly higher than similar domestic equipment.
At the center of the drum dryer, it is possible to avoid adding a dispersing mechanism. Wet materials entering the drying cylinder are repeatedly picked up and thrown off by the scraper on the drum wall. During the falling process, they are broken into small particles by the dispersing device, greatly increasing the specific area and fully contacting and drying with hot air.

The machine is mainly composed of rotating body, lifting plate, transmission device, support device, sealing ring and other components. A dryer is a cylinder that is slightly inclined from the horizontal direction. Materials are added from the higher end, and high-temperature flue gas flows into the cylinder together with the materials. As the cylinder rotates, the materials move to the lower end due to gravity. A copying plate is installed on the inner wall of the cylinder to pick up and sprinkle the material, increasing the contact surface between the material and the airflow to improve the drying rate and promote the material to move forward. The dried product is collected from the bottom and lower part

Composed of rotating device, supporting device, sealing ring and other components. It has the characteristics of reasonable structure, excellent production, high product quality, low energy consumption, and convenient operation. This device is 7-9% new and has good performance. It can be used immediately after installation

Continuous innovation is equally important. Products that must be accompanied by services are the true mechanical dryers. We have always taken "user *" as our business philosophy and "quality is the lifeline" as our core business operation, providing maximum convenience and satisfaction to every user.
The service system ensures that we can provide satisfactory services to every user.

Product Features:

The dryer has a large processing capacity, low fuel consumption, and low drying cost. Drying machines have the characteristic of high temperature resistance and can use high-temperature hot air to quickly dry materials. Strong scalability, designed with production margin in mind, even if the output increases slightly, there is no need to replace equipment. The equipment adopts a self-aligning tugboat structure, and the cooperation between the tugboat and the rolling ring is good, greatly reducing wear and power consumption. The specially designed gear wheel structure greatly reduces the horizontal thrust caused by the tilting operation of the equipment. Strong overload resistance, smooth operation of the cylinder, and high reliability.

Folding edit: Selection of heat carrier in this paragraph
The determination of the heat carrier and its high temperature depends on factors such as the properties of the solid material being processed and whether it is allowed to be contaminated.

1) If the solid material being processed is not afraid of high temperature and is not a post product, it is allowed to be slightly contaminated during the processing. A hot blast stove or flue gas can be used as a heat carrier to achieve high volume evaporation rate and thermal efficiency. For example, for drying materials with high moisture content imported, when the gas inlet temperature is 300 degrees, the volumetric evaporation rate of the dryer is 5kg/M3/h, and the thermal efficiency is 30% -50%; If the inlet temperature of the gas is 500 degrees, the volumetric evaporation rate is 35kg/M3/h; The thermal efficiency is 50% -70%. So for rotary dryers equipped with combustion furnaces that directly produce flue gas for processing materials such as ore, sand, coal, and calcium persulfate, gas fuels can be coal, oil, natural gas, liquefied gas, etc.

2) If the processed materials are not allowed to be contaminated and require high temperatures, our company's new product gas generator can be used as a heat carrier. This product is energy-saving, environmentally friendly, and has high thermal efficiency. If the local environmental protection requirements are high and you want to save energy and maintain hygiene, using a gas generator would be a good choice. Gas generators are at least 20% more energy-efficient than combustion furnaces, and also greatly reduce labor costs. Generally, gas generators can be operated by one worker without the need for continuous coal addition. In addition, gas generators can be used immediately after shutdown for up to 10 days without operation, and can continue to be used next time.

3) There is also an indirect heating method, where heat is transferred from the metal wall to the material being dried, such as an externally heated rotary dryer.

4) If the dried object is not allowed to be contaminated and is not allowed to be diluted by air, the heat should be transferred through the drum wall. At this time, the drum should be loaded into the brick room, and the outside of the drum should be filled with flue gas. Alternatively, a surface heat exchanger such as a central pipe or column pipe, sleeve, etc. can be installed inside the drum to use metal walls for heat transfer. The heat carrier can be flue gas, water vapor, or electric heating. In dry materials, only clean gas is used to remove evaporated moisture.
