11 common faults and solutions of drum dryer

1. Causes of non rotation: The motor of the drum dryer is burnt out; Loose or broken belt of drum dryer;
Solution: Replace the motor; Check whether each switch contacts well and whether the fuse is burnt out; Adjust the motor position or replace the belt;
2. Causes for excessive or low temperature of the drum dryer: Reversal of the fan blades of the drum dryer; The heating pipe is burnt out; The heating pipe leads are burnt out;
Solution: Switch the power supply phase lines; Changing the direction of rotation of the motor; Replace the heat pipe or the heat pipe wire;
3. Causes of loud noise in drum dryers: Uneven placement of workpieces; Unstable installation of drum dryer; Loss of oil or damage to bearings; The fixing bolts of the bearing seat are loose;
Solution: Stop the machine and place the workpiece evenly; Reinstall the stable dryer; Tighten the fixing bolts of the bearing seat again; Replace the roller dryer bearing;
4. Causes of brake failure: Excessive wear on the brake skin of the drum dryer
Solution: Replace the brake pad
5. The reason why the raw materials of the drum dryer cannot be dried at one time: the dryer is too small; Incorrect calculation of wind pressure and flow of the air network; Improper use of the dryer;
Solution: Increase the drying temperature of the drum dryer, but this method can easily cause fire in the dryer. The best method is to replace or modify the drying equipment; Require the manufacturer to recalculate the wind pressure and flow before providing a design change plan based on the actual situation; Consult with the drum dryer manufacturer to obtain equipment instructions and learn the correct usage methods;
6. Reasons for ignition of raw materials in the dryer: improper use of drying equipment; The drying equipment is too small to achieve the drying effect and forced heating causes fire; There is a problem with the design principle of the drying equipment; The raw material cannot be sucked away, resulting in a fire in the dryer;
Solution: Consult with the manufacturer to obtain equipment instructions and learn the correct usage methods; Replace or modify the drying equipment; Require the manufacturer to replace or modify the drying equipment; Check whether the drying equipment is installed correctly, whether there is air leakage or increased wind pressure;
7. The cause of dryer blowout: the drying temperature is too high, causing a fire and combustion in the drying equipment; Blockage of drying equipment;
Solution: Reduce the drying temperature; Cleaning and drying equipment;
8. Causes of material suction failure: Improper installation of drying equipment, air leakage, or incorrect installation; Drying equipment design issues, insufficient wind pressure;
Solution: Check whether the installation is correct according to the installation drawings, and check whether there is air leakage at the pipeline interface; Coordinate with the drum dryer manufacturer for solution;
9. Causes of separator chimney discharge or lower outlet steam discharge: the separator is too small; There is a problem with the separator design; Wind pressure calculation error of air network;
Solution: Replace or modify the separator; Negotiate with the manufacturer for solution;
10. The material is uneven in dryness and wetness, and the front rod making cannot work properly. Reasons: Improper use of drying equipment; Raw material agglomeration;
Solution: Consult with the manufacturer to obtain equipment instructions and learn the correct usage methods; Crush the agglomerated raw materials and then dry them;
11. Reasons for waste of fuel in drying equipment: poor thermal insulation performance of drum dryer equipment; There is a problem with the equipment design principle; There are problems with the design and manufacture of the furnace;
Solution: Wrap a layer of insulation material to improve the working condition of the drying equipment; Demand improvement methods from manufacturers; Consult the manufacturer for more reasonable furnace drawings
