The dryer is a kind of processing a large amount of material drying equipment, has the high efficient production performance is one of the users more concern, as the country in recent years, with the idea of energy conservation and environmental protection advocates, now drying equipment in the guarantee of efficiency and output at the same time also more and more pay attention to the improvement direction of energy saving, one of the larger extent reduce the heat loss is the one of the important link.

In the process of material drying: the wet material is sent to the hopper by the belt conveyor or the bucket elevator, and then the hopper feeder through the feeding pipe into the feeding end. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the dryer. The rotary drum is a rotating cylinder with a slight tilt to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, which is in countercurrent contact with the material. There are also heat carriers and materials flowing together into the cylinder. As the cylinder rotates the material is moved to the bottom end by gravity. Industrial dryer as a more commonly used drying equipment in the mineral processing industry, in the rising raw materials today, we always adhere to the route of environmental protection and energy saving, so that the user, let the dryer user really feel the care from the manufacturer, can continue to expand our dryer equipment market.

Adjustment method of ventilation volume of sand dryer

Ensure the ventilation volume of the sand dryer, grasp the temperature of the dryer at any time, and add fuel according to this to achieve energy-saving drying state. The ventilation of the sand dryer is mainly between the drying cylinder of the dryer and the hot blast stove. It can use natural wind or artificial wind, and then blow the air volume to the cylinder of the dryer. The key parts of the best-selling exhaust management are flip valve and flash valve. Good operation of these two parts can ensure smooth exhaust and good ventilation. First of all, we should learn to judge the good and bad ventilation situation by ourselves. We use a simple way, first of all, we wet our hands, and then reach out to the outlet, so that if after a while the water on the hand is evaporated, it means that the ventilation is good, otherwise the ventilation is not good, need to adjust. Of course, this is a simpler and more effective way to judge.
