How rotary dryer apparatus jet type hot-air furnaces:
1. Check whether all parts of the supporting fan are in a normal state before ignition of the rotary dryer.
2. After ignition, the smoke machine should be started. After 5 to 7 minutes of normal combustion, the main fan must be started to avoid burning the furnace core and affect the service life.
3, when adding coal should be done less, diligent, fast, even coal, coal seams covered with furnace, and pay attention to loose coal seams, remove ash, keep the furnace smooth.
4. If you want to reduce the air temperature, adjust the damper of the small smoke machine and add coal pressure. If necessary, the smoke eliminator can be suspended and the furnace door can be opened to achieve rapid cooling.
5. When the machine is shut down, the smoke machine should be closed first, the furnace door should be opened, and the air temperature should be reduced to below 60 °C after the coal is burned or smoldering, then the main fan should be stopped to ensure that the residual heat does not damage the furnace core.
Rotary dryer hot air stove maintenance:
1. During use, the flue should be cleaned before each ignition. The ash can be adjusted to the maximum opening degree by the induced draft fan. The exhaust pipe is ventilated for about 5 minutes, and the ash is extracted to keep the smoke. The ring has a higher heat exchange efficiency.
2. Pay attention to the temperature rise of the main fan and the smoke machine during the use process. The temperature rise of the motor does not exceed the specified value. The temperature rise of the rolling bearing does not exceed 50 °C, and the temperature rise of the sliding bearing does not exceed 35 °C.
3. Check the oil mark of the housing of the hood, keep the lubricating oil above the specified marking line, and the temperature rise of the oil should not exceed 40 °C.
4, always check the furnace, observe whether the lining is intact, if it falls off, it should be repaired in time to avoid burning the furnace.
5. Pay attention to check the sealing surface of the joint surface of the furnace floor and the basic flue. There should be no leakage of cold air. If there is any leakage, it should be sealed and repaired in time. Zhengzhou Hengxing Equipment Co., Ltd. has domestic first-class production equipment and sophisticated testing equipment. Every step of the rotary dryer product has undergone rigorous testing to ensure that the products meet the highest standards at the factory.

High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".

This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.

The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.

Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.

The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
