polyester spiral dryer screen mesh for paper machine

Description：

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.

Working Principle of equipment drying room:

 The multi-layer dryer is a batch and continuous production drying equipment. The main heating methods are electric heating, steam heating, hot air furnace heating and gas heating. The main principle is to evenly spread the material on the mesh belt. The mesh belt adopts a 12-60 mesh steel mesh belt, which is dragged and moved in the dryer by the transmission device. The hot air flows through the material, and the water vapor flows from The drainage hole is discharged to achieve the purpose of drying, and the length of the box body is composed of standard sections. In order to save the space, the dryer can be made into a multi-layer type, and the common ones are two-room three-layer, two-bedroom five-layer, four The room has five floors, four rooms and seven floors, etc. The length is 6-40m, and the effective width is 0.6-3.0m.
