Second-hand sand coal drum dryer is an important industrial equipment, which is widely used in drying operations in coal, ore, sand and other fields.
This article will conduct an in-depth analysis from the working principle, advantages, application fields, etc., so that readers can have a deeper understanding of the device.
1.Working principleThe second-hand sand coal drum dryer adopts the working principle of drum type hot air drying.
The hot air is generated by the preheating furnace, and the hot air is introduced into the drum through the fan, and materials such as coal or sand are constantly turned and collided under the action of the hot air inside the drum, so as to achieve a fast drying effect.
2.Advantage (1) High efficiency and energy saving:
The second-hand sand coal drum dryer uses convection to dry, the hot air is in full contact with the material, the heat transfer efficiency is high, the drying speed is fast, and the water in the material can be quickly evaporated.
At the same time, a variety of energy-saving measures are set up inside the equipment, which can minimize energy consumption and improve energy utilization.
2) Dry evenly:
The drum type hot air dryer adopts the method of flipping and collision, so that the material can be evenly dried inside the drum, which avoids the problem of local drying or over-drying that is easy to occur in the traditional drying method.
3) Easy maintenance:
The equipment adopts a fully enclosed structure, which effectively prevents hot air leakage, reduces hot air loss and dust pollution, and also makes the maintenance of the equipment more convenient.
3.Application fieldSecond-hand sand coal drum dryer is widely used in drying operations in coal, ore, sand and other fields.
For example, in the coal industry, coal drying is an important process, which can effectively improve the calorific value of coal and reduce transportation costs.
In the ore industry and building materials industry, the drying of stones, ores, sand and other materials is also an indispensable process.
