With the acceleration of China’s industrialization process, various mineral raw materials play an important role as the basis of industry. These mineral materials contain a certain amount of internal moisture, which brings inconvenience to the follow-up utilization. Therefore, they must be dried quickly to make the final moisture meet the industry standard, so that they can be applied to industrial production on a large scale.

The gypsum powder dryer is a horizontal cylindrical rotating device. During the rotation, the internal drying medium is in full contact with the wet gypsum powder. The gypsum absorbs the heat of the drying medium, and discharge out of the cylinder during the rotation. Gypsum rotary dryer has the advantages of reliable performance, low failure rate, stable operation, high operation rate, large daily processing capacity, energy-saving, etc. The annual processing capacity is 50,000-200,000 tons according to the user’s demands.

Bentonite clay is a kind of water-bearing clay mine mainly composed of montmorillonite. After drying with a bentonite dryer, it can be expanded by adding water and treated repeatedly, which makes bentonite more widely used in machinery, metallurgy, drilling, petroleum, chemical industry, food, environmental protection, etc.

Slag is a kind of waste residue in ore dressing process, which is high-quality recycled material in the industrial field. Because the water content in slag is relatively high, it needs to be dried, which requires a slag dryer. The whole set of slag dryers has the advantages of reasonable design, excellent production, stable performance, advanced technology, high output, low energy consumption, small floor area and a high degree of mechanization. After the improvement of our technicians, the slag dryer is special good in the treatment of high humidity materials.

Kaolin clay is an important clay mineral, which is mainly used in papermaking, refractory, ceramics and other industries. With the increasing demand for kaolin in various industries, the traditional exposure drying method dryer has been far from meeting the production demand. The kaolin meets the market development demand and has become the equipment for kaolin dehydration and drying. The kaolin dryer adopts a new type of lifting plate device, which can make the kaolin evenly distributed in the radial section of the dryer, make the material curtain thin, uniform and complete, fully contact the hot air flow, and achieve the purpose of making full use of heat energy.

Sand dryer is three-drum drying equipment for processing a large number of materials. It is generally suitable for drying granular materials, especially for drying sand, river sand and quartz sand with an excellent drying effect. Due to the reliable operation, simple operation, strong adaptability, large processing capacity, energy conservation and environmental protection, the rotary sand dryer is widely used in building materials, chemical industry, casting, wall insulation and other industries.

As a solid combustible, coal is known as black gold and industrial food. The depth and breadth of coal processing are developing rapidly, the output of coal has risen significantly, and the coal drying industry has also developed rapidly. A coal dryer is a special equipment for drying various kinds of coal. The coal dryer has a good drying effect and can dry the moisture in the coal with high efficiency and energy saving. This has huge economic benefits and protects the environment, and has been welcomed by many coal enterprise investors.

According to the characteristics of coal slime, our company developed the coal slime dryer. The drying temperature, pressure, air volume and speed of the dryer are strictly controlled, And through different forms of lifting devices, cleaning devices and crushing devices inside the drum, the wall sticking problem in the process of coal slime drying can be well solved.

Because fly ash contains certain moisture, it needs to be dried and dehydrated by drying equipment to make the moisture content less than 5%. After drying and dewatering, fly ash can be widely used in cement plants as raw materials and water conservancy projects., Concrete products and many other fields, which not only solve the problem of fly ash pollution to the environment but also realize the comprehensive utilization of solid waste. Therefore, Dongding specifically manufactured a fly ash dryer according to the characteristics of fly ash.
