The raw materials to be treated should distribute on the conveyer belt through suitable mechanism such as star distributor, swing belt, crusher or granulator, the conveyer passes through the channel including of one or several heating unit. Each heating unit is equipped with air heater and circle system. Each channel has one or several damp discharge systems. When the conveyer passes through it, hot air will pass through the raw material from up to low or from low to up. In this way raw materials can be dried evenly.
II. Application of belt dryer/drying machine:
The belt dryer is ordinary continuous drying equipment. It is widely used for chemical industry, foodstuff industry, pharmaceutical industry, construction materials industry, electronic industry and so on. Especially it is suitable for drying raw materials that are good in breathability and have the shape of pieces or strip of granule. It is also possible to dry the pasted raw materials such as filter cake after shaped through granulator or extruder.
III. Features of belt dryer:
1. Air quantity, heating temperature, materials staying time and feeding speed can be adjusted to achieve the best drying effect.
2. The equipment configuration is flexible, mesh belt washing system and materials cooling system can be used.
3. Most air is recycled to realize saving energy.
4. The machine is equipped with unique air dividing apparatus, it makes the hot air distribute uniform better and guarantee the quality of products is constant.
5. Heating source can be steam, conduction oil,, electricity, coal (oil), or hot air furnace.
