Improve the system under the drum dryer feed Chute prevent burn: tumble dryer when the ventilation rate is too small, to improve the damper height so that the front of the firing zone in a negative pressure environment, the rear material under positive pressure environment calcination. Holding position while maintaining the position of the inlet and the cooling air flow in order to improve the quality of combustion and heat exchange efficiency of the fuel, the elimination of under-fire phenomenon within the air-dryer. Reduce heat empty, extended residence time, increase the heat exchange efficiency, reduce the loss of hot gas. To drum drying machine detects the temperature of the dryer according to the trend of the temperature within the lignite dryer temperature accurately determine, and as a basis for the amount of the external fuel control. Dryer to prevent the front end without material sawdust dryer machinery, high temperature burn ring and cylinder block material, trenching Chute raised, is conducive to high-temperature gas flow and prevent burn Chute small tumble machine, material and form a material curtain fall naturally, in direct contact with the hot gas, heat exchange rate. Installation parts are available from the middle of the dryer drum head start in order to install the 3-5 end set of X-type lifting plate, the separation distance 0.5 ~ 1mm, each group of six X-type lifting plate. But near the end of the nose can not be installed within 3m, otherwise it will affect the overall drying efficiency. Transformation feed tube angle, it does not affect the feed, as far as possible down the barrel increase over end not in contact dryer ring gauge is appropriate, but not too long deep interior of the cylinder mesh belt dryer manufacturers, It can be controlled from the block material blanking point circle within 200mm. Refractories can build sand dryer prolong life: sand dryer to avoid excessive leakage into partial condensation caused by cold air, the same parts to be welded to prevent leakage welding and vulnerability; such as windscreen to improve the uniformity of the water 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; the bag material and corrosion within the device list, you must adapt with them, in order to ensure life. Sand dryer adjustment roller to simultaneously adjust the four roller dryer, and ensure that the contact surface with a roller wheel with no 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. Prospects small corn dryer is naturally very widely by Fu Machinery Manufacturing Co. Gongyi City. Gongyi City Fu-wah Machinery Manufacturing Co. (www.hgj520.com) (www.fhhgj.com) strong, credible, in Zhengzhou, Henan machinery and industrial products industry cooperation projects accumulated a large number of loyal customers.
