For sawdust drying machine, it is very important to match the heating capacity of the hot blast stove. Even if the residence time of the materials in the sawdust dryer is ensured, the feeding is even, and the ventilation and dust removal equipment is reasonable, but the lack of heat source or temperature control is directly related to the non drying of the sawdust and the unqualified products.
The retention time of sawdust in the rotary sawdust dryer must be guaranteed. Then, how to improve the filling rate of sawdust and prolong the residence time of sawdust in the dryer cylinder ? How to increase the cylinder and the cyclone dust collector to cover the insulation felt and do the external insulation so as to reduce part of the heat loss ?
The rigid labyrinth type is adopted for both the feed and discharge seal rings, which solves the problems of poor sealing effect and easy burning. In order to ensure the relative stability of the parameters of the sawdust dryers machine, a quantitative feeding device is added according to the sawdust characteristics, and the feeding speed is arbitrarily controlled by a stepless speed regulating motor.
