Refractories can build sand dryer prolong life: sand dryer to avoid excessive caused by cold air from leaking into how much money local condensation sawdust dryer, same welded parts to be welded to prevent leakage and vulnerability; Such a windscreen can raise the moisture uniformity after drying grain, but also enhance the thermal efficiency of the dryer, while not affecting the normal exhaust gas of the drying section. Dryer humid environment because there exists a certain amount of sulfur dioxide; inside the bag material and equipment sawdust dryer sheet pipeline corrosion, must adapt with them, in order to ensure life. Sand dryer adjustment roller to simultaneously adjust the four roller, and ensure that the contact surface with the idler wheel is not less than 50%. Adapt to high moisture, high dew point, having a hydrophobic filter to the line, to ensure that no paste bag, easy to eliminate surface dust; housing have good insulation, ensure that no internal condensation; performance discharge air lock device better. The service life of refractory sand dryer depends on operating conditions, the corresponding process, as well as the choice of refractory materials, proper masonry methods. Refractory masonry correctly and effectively is the key to life of the machine, not only help to prolong life, but also to eliminate sand dryer equipment should lead to premature failure of some of the stress; errors masonry method will greatly shortening refractory life. Forage dryer equipment only when substantial progress in the stage production, but also reduces coal consumption to some extent, reduce the pollution of the atmosphere. For the community to bring more efficiency and value. When dried under the same conditions, the drying rate is not the same. Easy to dry forage than clay, and clay with larger viscosity dried clay is more difficult than the clay loose structure. Compact size sawdust dryer dryer drying forage materials, structural properties of materials, different properties, which in combination with the water way is different. Forage dryer material by increasing the contact time with the hot air in the cylinder axis and the contact area per unit length, through the transformation of lifting plate to improve the dispersion of the material in the cylinder cross-sectional purposes sawdust dryer can also be achieved by increasing the length of the dryer cylinder. The flow rate of the hot air from the heat and mass transfer theory shows, increase the flow rate of dry air directly improve the heat transfer coefficient and mass transfer coefficient, the drying rate increases, but also timely replacement of hot air, it is conducive to external diffusion process. However, to improve the hot air flow rate, for a certain length of the dryer, the hot air is reduced in the dryer cylinder body residence time, it is possible to influence the thermal efficiency, resulting in waste of heat.
