Description of DW Belt Dryer
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.
Application of DW Belt dryer
The belt dryer is an 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.
Features of DW Belt Dryer
1,Hot air go through material layer from bottom to top and from top to bottom, it increases the contact area of material and hot air and also the drying intensity.
2,We adopt unique internal air blowing device. It not only increases the relative speed of material and hot air and drying intensity bu also the uniform drying of materials.
3,It is fully enclosed structure.Ther is no outer air pipes except the dehumidifying air pipe,thus the materials won’t be polluted and the heat efficiency and working condition are improved.
4,It is easy to contact with all parts inside the main machine,so it's easy for cleaning.
5,The belt speed can be controlled easily to guarantee the final moisture of products.
