Fly ash rotary dryer is also known as the three layers of drum dryer, three return cylinder dryer, on the basis of the single cylinder dryer, developed and manufactured,which is an industrial dryer on non-viscous, liquid material .At present three-cylinder dryer made by Dingli company,with mature technology, through the drying of the sand, fly ash, fly, mineral materials, slag and other material , the effect is very good.However, in the process of using the fly ash dryer, sometimes there are some problems, so what should we do?Today, I will introduce the common faults and treatment methods of fly ash dryers.
1. Causes of no rotation: the fly ash dryer motor burns out; the fly ash dryer belt is loose or broken;
Solution: replace the motor; check if the contacts are in good contact, if the fuse is blown; adjust the motor position or replace the belt;
2. Causes of the temperature of the fly ash dryer is too high or too low: fly ash dryer fan blade reversed; heat pipe burned out; heating pipe conductive wire burned
Solution: adjust the power phase line; change the motor steering; replace the heating tube or the heating tube conductive line;
3. The noise of the fly ash dryer is large: the workpiece is placed unevenly; the drum dryer is not installed stably; the bearing loses oil or is damaged; the bearing seat fixing bolt is loose;
Solution: stop and place the workpiece evenly; re-install the smooth dryer; re-set the bearing block fixing bolt; replace the fly ash dryer bearing;
4. The cause of brake failure: excessive wear of the brake ash of the fly ash dryer
Solution: replace the brake pads
5. Fly ash dryer raw materials do not dry for a reason: the dryer is too small; wind network wind pressure, flow calculation is wrong; improper use of the dryer;
Solution: increase the drying temperature of the fly ash dryer, but this method is easy to cause the fire inside the dryer. The best method is to replace or re-modify the drying equipment; Require the manufacturer to recalculate the wind pressure and flow rate and then according to the actual situation. Provide design change plan; negotiate with the fly ash dryer manufacturer to obtain the equipment manual to learn the correct use method;
