The municipal solid waste dryer machine is a forced drying plant of waste plastics with water content. The retention time of the material in the dryer machine is decided by the internal temperature of the dryer machine and the moisture content. For light material which is material with 80%-90% plastics (the others are rubber and cloth), it should be dried when the moisture content is 4%-10%. This machine can provide material with high quality for the subsequent harmless pyrolysis, thus ensuring normal production.

The municipal solid waste dryer machine is designed according to the material features such as heated temperature, moisture content, drying degree and time required. This machine is equipped with drive roll, driven roller, adjusting device, top riding wheel, bottom riding wheel and iron conveyor. The heat energy required is provided by the flue gases of the pyrolysis furnace which means secondary utilization of the waste heat, thus saving energy. The gas with waste heat will enter the internal of the dryer machine through pipes to realize pipe heating. The internal temperature of the dryer machine should not be too high. The retention time of the material in the dryer machine and the speed of the drive roll are decided by the internal temperature of the dryer machine and the moisture content. The layers of the dryer machine is decided according to the production process. The production is carried out in the machine body so that it has the following features: fully sealed, no leakage, no pollution. The machine is equipped with a ventilator. There is a air flow distributor to realize reasonable, uniform and adjustable air flow distribution. There is also a axial flow fan at the top to ensure air circulation inside the dryer machine. It can realize continuous production, programmed control, automated operation. The internal operating and working state of the dryer machine can be monitored through video in time.

1. This municipal solid waste dryer machine has reliable performance, normal operation, no noise and chain transmission.
2. It has small floor area, high efficiency and easy operation and maintenance.
3. This machine works under fully sealed state so that there will be no pollution which means that it is safe and environment friendly.
4. The utilization of heat energy and the efficiency are high while the energy consumption is low.
5. It is a temperature controlled and speed adjustable electrical equipment which has the following advantages: good performance in advancement, understandability and simple operation.
