Sawdust dryer refers to the granule-like wet sawdust, using screw conveyor continuously added to the drying tube. In the transport and dispersion of high speed hot air, allowing moisture evaporation of wet materials, the process of obtaining a powdery or granular dried product. Mainly by air heater, feeder, air drying tube, cyclone, fan and other components. Sawdust dryer features: 1, dry strength, because the material highly dispersed in the gas stream, the entire surface of the particles of active dry the effective area. 2, 3 drying time is short, simple air dryer, small footprint, easy to build and repair. 4, large capacity, high thermal efficiency. When dry unbound water, thermal efficiency up to 60%. Each large machines, which can be in operation to bring greater efficiency, but also the percentage of companies among the largest accident of a staff in use of the process, since no standardized method of operation, resulting in personal injury or loss of business interests. 1, prior to boot, you should first check the power of engagement, a fixed position of the drum is correct, connect the power, open the cover, turn the motor switch, so that the drum idle running, turning the housing should be standard pointing arrow shown the same, turning electric wire after five minutes of work, yet there is hot air discharge should stop checking electric wire exhaust vents are blocked. 2, dry work should put down the lid, loading and unloading of the workpiece to be shut down, pay attention to the work piece to be evenly distributed in the drum, otherwise the centrifugal force is not parallel, dehydration opportunities shaking violently. Rotating cylinder workpiece can not be overloaded, do not overfill, if drying the workpiece small density, or easy to store liquid by centrifugation and dried for 1-2 minutes, remove the micro switch, flip the workpiece position, centrifugal drying during heating in order to achieve satisfaction effect. 3, to make the drum is stopped, the first motor is shut down, and then the foot brake pedal, but can not remember off the motor brake. Dehydration may be individually heated centrifugal drying, but can not shut down the motor independently heated and dried. 4. Before using dryer, reference should read the instructions, understand the principle of operation, in order to ensure safety in production, should be inspected regularly and maintain a good dryer, regularly add high-quality bearing grease to maintain good dehydrator.
