The van type rotary drum dryer can be divided into advectional current van type drum dryer and side current rotary dryer. When the air in the drying chamber is evacuated, it become the vacuum van type drum dryer. We should choose the right rotary dryer type according to the different characteristics of the material. Now Bailing Machinery will introduce the method to choose the rotary drum dryer:
The air quantity of the fan: the air quantity is determined by the theoretical value and the distribution flow of the drum dryer. But in the trolley van type drum dryer, there is certain gap between the drying chamber and the trolley. The air quantity passes by is relatively more in the air of little resistance and the wheel installation space.
The speed of the hot wind: to ensure the drying quality, we always adopt the method of decreasing the internal recycle hot blast temperature and reduce the material bed thickness. The bed of material is determined by the test which is usually 10-100mm.
The layer of product: in the rotary drum dryer, the channel size of the air flow has a great influence to the air. The air flow direction and the distribution in the product layer are related to the flow rate. So considering the interval between the material layer and the wind direction control is the important factor to ensure the flow rate.
The rotary drum dryer is of reasonable price and reliable quality. We attach great importance to the product quality. Our rotary drum dryer products have passed through the international quality system authentication. The rotary drum dryer main spare parts adopt the superior anti-friction material and the advanced processing technology. The series of rotary drum dryer is durable, and enjoys popularity at home and aboard. Welcome to visit us.
