Belt dryers have proven to be the most stable, fire-safe and accident-free type of equipment for drying wood waste. This is achieved due to the fact that the that the removal of moisture from the wood does not occur from the interaction of the material with flue gases, but is the result of exposure to hot air coming from heat exchangers.

The principle of belt dryer operation

The wet raw material is fed to the loading module of the dryer, where a layer of material is formed and its stable level over the entire area of the belt is carried out.

Due to the air rarefaction created by exhaust fans, the air passes through heat exchangers, where it is heated to the required temperature, and then goes through a layer of material lying on the belt.

The texture of the belt provides minimal resistance to air flow, which ensures maximum efficiency of exhaust fans, and the size of the tape cells ensures the content of wood dust in the air within 10 mg/m3.

The moisture removed from the wood, passing through the "clean" zone and exhaust fans, is released into the atmosphere through the air ducts.

The humidity of the material at the outlet of the drying unit is controlled by a humidity sensor, whose readings regulate the time when the raw material is in the drying zone, thereby ensuring a stable humidity of the material at the outlet of the drying unit.

The main advantages of belt-type dryers:

low operating costs

high reliability

full automation of the process

fire safety

moisture is removed from the material in a gentle way

high granules quality due to uniform removal of moisture from raw materials

modular design that ensures low assembly costs, as well as minimizing investments while increasing productivity
