Detailed classification and application fields of dryers

Dryer equipment Today, its application field has covered many production and processing industries, and its classification is becoming more and more perfect. The classification methods are also various. The commonly used ones are divided by composition structure, which can be divided into the following four categories.

Detailed classification of dryers

1. Vertical dryer

 Vertical dryer

The vertical dryer is not based on the traditional drying furnace. However, under the condition of no rules to follow, in the face of large investment, large floor area and high failure rate, according to the drying characteristics of industrial briquette, using the principle of low temperature, large air volume and gravity, the product has been successfully developed for several years through R & D design, industrial test, product upgrading and large-scale operation.

In the product, it fully embodies the characteristics of applicable innovation, expanding efficiency, reducing cost and improving. Safety production and environmental protection are ideal equipment for briquette production line drying. Vertical dryer is mainly used to dry briquette, grain, corn, etc. common vertical dryers are grain dryer and corn dryer.

2. Mesh belt dryer

Mesh belt dryer is a kind of continuous drying equipment which uses steel mesh as conveyor belt to carry materials for continuous drying, which is suitable for flow operation. Because the conveyor belt is reticular, it is suitable for drying regular or irregular lumps (such as: coal block, various mineral powder molding fast, food, vegetables, etc.).

This machine can be used together with other equipment or used alone. It can be widely used in food processing, chemical fertilizer, chemical industry and so on.   

3. Drum dryer

 rattler-drying machinery

rattler-drying machinery It is a horizontal dryer, also known as rotary dryer, rotary dryer, etc. it is a common drying equipment in the market at present. The equipment has simple structure, low price and wide application range. It is the product of many users. It is mainly used for drying materials with low water content such as coal slime, fly ash, sand, quartz sand, chicken manure, etc.

4. Heat conducting tubular dryer  

The heat conduction tube dryer is a new type of energy-saving drying equipment. The equipment occupies a small area, and the materials are dried well. At the same time, the hot gas recovery device is added at the tail, so that the heat can be reused, and the energy is not wasted. This machine adopts the structure of heat conduction tube, and the material is heated indirectly through the heat conduction tube. The material passes through the gap of the heat conduction pipe, so that the material and heat source can be fully contacted, and the steam generated by drying can be discharged from the top in real time. The equipment has the advantages of reasonable structure, convenient operation, wide application range, high efficiency and energy saving. It is mainly used for drying high humidity materials such as sawdust, sawdust, sawdust, bean dregs, bean dregs, cassava dregs, sweet potato residues, fruit dregs, etc.

Application field of dryer

The type of dryer used in each occasion is also different, here we briefly make a summary.

1. Chemical industry, miner, metallurgy and other industries, such as ore, slag, coal, metal powder, clay, diatomite, kaolin.

2. Agriculture, feed, fertilizer industry, such as straw, grass, leaves, fish meal, corn sauce, starch residue, distiller's grains, medicine residue, fruit residue, soy sauce residue, bagasse, peat, organic compound fertilizer, sludge, aquatic product waste, food factory waste, slaughterhouse waste, organic fertilizer, inorganic fertilizer, phosphate fertilizer ammonium sulfate.

3. Dry powder and granular materials with special requirements. Such as various crystals, light calcium carbonate, activated clay, magnetic powder, graphite, inorganic mud, clay, lime slurry, ore slurry, phosphorus slag, aluminum red mud.

4. Materials requiring low temperature drying and mass continuous drying.

The above four fields show that the industries suitable for dryer include industry, agriculture, chemical industry, mining, metallurgy, etc.
