Sawdust dryer is widely used in the drying process of sawdust. The untreated sawdust usually has high moisture content, which needs to be reduced to the standard of safe storage. The traditional drying of sawdust is usually natural air drying and sun drying. This method is simple, easy to operate and low cost, but limited by natural conditions, low efficiency, long cycle and easy to lead to a large number of sawdust mildew, resulting in unnecessary losses.
The sawdust drying machine is a kind of continuous and indirect heating dryer with large production capacity. Through the heat medium exchange, the moisture in the sawdust is evaporated to realize the drying of the sawdust. The sawdust dryer machine has the advantages of low rotation speed, low fluid resistance, less power consumption, large production capacity and large adaptability.
During the operation of the rotary drum sawdust dryer, the feeding end is slightly higher than the discharging end. The wet sawdust enter from the high end and are dried by effective contact with the hot air in the rotary dryer. With the help of the slow rotation of the cylinder, the dried sawdust are discharged from the low end under the effect of gravity. The cylinder is the base of the rotary kiln of the dryer. It is an important part of the exchange between the material and the hot medium.
At the same time, it also carries the weight of the sawdust and transports the sawdust. The wheel belt is set on the cylinder ring device, and the weight of all rotating parts such as the cylinder and materials are transmitted to the supporting device through the wheel belt, so the stability of the cylinder is increased. The design of the sawdust dryers must ensure that the cylinder and the wheel belt have sufficient rigidity and strength.
