Adjustment Method of Ventilation Volume of Sand Dryer

Ensuring the ventilation rate of sand dryer, grasping the temperature in the dryer at any time and adding fuel accordingly can achieve energy-saving drying state. The ventilation area of sand dryer is mainly between the drying barrel and the hot stove. It can use natural or artificial air, and then blow the air into the barrel of the dryer. The key parts to manage the best-selling exhaust air are flip valves and flicker valves. Only when these two parts are properly operated, can the exhaust air be smoothly and well ventilated. First of all, we should learn to judge whether the ventilation is well or not. The first simpler way is first we wet our hands, and then extend our hands to the outlet. In this way, if the water on our hands is evaporated in a short time, it means that the ventilation is well, otherwise the ventilation is not good and needs to be adjusted. Of course, this is a relatively simple and effective judgment method.
