Summary: The raw material to be treated is distributed on the conveyor belt through right mechanism such as star distributor, swing belt, crusher or granulator. The conveyer passes through the channel consisting of one or several heating units ,which are equipped with air heating 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 up and down. In this way the raw material can be dried evenly. Application: The belt dryer is continuous drying equipment. It is widely used for chemical, food, pharmaceutical, construction materials and electronic industries. It is especially suitable for drying raw materials that are good in breathability and in the shapes of piece , strip or granule. It is also possible to dry the pasted raw material such as filter cake after shaped through granulator or extruder.
