How to debug the gypsum dryer

How to debug the gypsum dryer?
How can we ensure the ventilation rate of the sand dryer? Of course, we must keep track of the temperature of the dryer at any time, and some materials must be added according to the fuel to achieve energy-saving drying. The sand dryer is in the The ventilation part is actually mainly between the drying cylinder and the hot blast stove. The following three-cylinder dryer manufacturers will talk about it with you.
The key parts for managing the best-selling exhaust air are the flap valve and the flashing valve. Only by operating these two parts well can the exhaust air be smooth and well ventilated. First of all, we must learn to judge by ourselves whether the ventilation is good or bad. We use a simpler method. First, we wet our hands, and then extend our hands to the outlet. In this case, if the water on the hands evaporates after a while, it means that the ventilation is good, otherwise the ventilation is not good and needs to be adjusted. Of course, this is only a simpler and more effective judgment method.

Adjustment of ventilation volume Manufacturers of three-cylinder dryers can debug in the following ways:
1. Pay attention to the air leakage between the flaps, especially the sealing of the bearing parts. And prevent the large slag, bricks, iron wire and other debris from falling into the flap valve. Causes deep wind, and even hinders the discharge or jams the flap, which cannot be turned over.
2. Observe how much the flap valve is blanking and the size of the blanking interval, whether it is compatible with the discharging speed of the sludge dryer. Do not store too much material in the tipper to affect the discharge. Don't store too little material, and the vibration must be complicated.
3. Refuel the shaft oil cup on time. Twist 1~2 times per shift, and you can rotate one button every time. For the flash valve, it is necessary to observe whether the operation is flexible, whether the feeding is smooth, whether the position of the counterweight is appropriate, and whether the triangular cone is in tight contact with the feeding nozzle. The counterweight can be adjusted appropriately according to the condition of ash accumulation and feeding. The triangular cone is usually movably linked to the lever. In order to prevent the flashing from shifting due to vibration, it can also be fixed and welded on the lever after aligning the discharge nozzle.
