The drying work capacity of the drum dryer equipment is related to the dryness and wetness of the material, and also to the selection of the heat source. High-humidity materials, if the drying is not sufficient, the dried materials will be slightly moist, and the choice of heat source is also critical.

High-humidity materials, if the drying is not sufficient, the dried materials will be slightly moist, and the choice of heat source is also critical.
Selection of heat source: There are many heat source equipments for the drum dryer equipment. They are usually classified according to the fuel consumed. There are coal, fuel, gas, electricity, etc. According to the heat transfer, they can be divided into drying medium and directly heated. And indirect heating type. For example, the boiler heats water to form water vapor, and the water vapor heats the drying medium through the radiator. This is two indirect heating. The overall thermal efficiency is low, only about 40%. In some factories, there are many hot spots. In order to facilitate centralized heating and management, more is used. The coal-fired hot blast stove has indirect heating and direct combustion flue gas as the drying medium (direct fire furnace), and the indirect heated hot air is clean and the thermal efficiency is 60-70%. The direct heating is affected by the pollution of the smoke, which affects the quality of the product. However, the heat energy is fully utilized and the thermal efficiency is very high. When the material is mixed with a small amount of smoke during drying, it has priority. Oil burners are also used more and more now, and have the advantages of simple operation, rapid temperature rise, stable temperature, convenient control, and low cost of use.
The reasonable choice of heat source has a great influence on the drying efficiency of the tumble dryer. It involves the investment cost of the dryer equipment, the hot air temperature, the drying quality of the materials, the drying cost, the environmental protection, the labor intensity of the personnel, and the automatic control. Level and so on. Zhengzhou Hengxing Equipment Co., Ltd. has domestic first-class production equipment and sophisticated testing equipment. Every step of the drum dryer product has undergone rigorous testing to ensure that the products meet the highest standards at the factory.

Submission:
Metal sheet & tube Laser Cutting Machine available for metal plate and tube cutting in various materials such as stainless steel, carbon steel, alloy steel, spring steel, copper, aluminum, gold, sliver, titanium etc.
Metal sheet & tube laser Cutting Machine advantage:
1. Auto - focus
Applicable to various focal lengths, which are controlled by machine tool control system. Focal point will be automatically adjusted in cutting process to achieve the best cutting effect of different thicknesses sheets metal.
2. Free
Focal length is controlled by operating system. We don`t need to do manual regulation, which effectively avoids errors or faults caused by manual operation.
3. Fast
Auto focus would automatically adjust the most appropriate focal points in the process of punching and cutting, which greatly improves cutting speed;
4. Accuracy
Metal sheet & tube laser cutting machine with increasing perforation focus length, separately setting perforation focal length and cutting focal length, enhance cutting accuracy.
