Hollow paddle dryer installation and commissioning steps

Guide: Installation and commissioning steps of the hollow blade dryer :

1. Before installation, check that the parts are intact and clean the inside.

2. After installation, check whether the grease has been injected into the bearing housing before commissioning. Otherwise, the proper amount of grease should be added. Generally, the molybdenum disulfide compound calcium base grease or other high temperature resistant grease is used.

3. Before installing the rotary joint, carefully read the rotary joint "Instruction Manual" and install it correctly to prevent damage to the gasket.

4. A pressure gauge and a voltage regulator are required on the heating or cooling medium inlet line. A safety valve must be installed in front of the inlet to prevent overpressure of the equipment. The temperature of the heating medium must not exceed the rated service temperature.

5. For the rotary joint with single-end configuration at the end of the shaft, it should be noted that the surface within 200 mm of the end of the nozzle extending into the inner cavity should be smooth and non-porous, free from rust and slag, and can be heated (or Cooling) The sealing requirements of the media are of a suitable size. As with the double-end installation of the rotary joint, the whole machine must be commissioned after the pressure test is not leaked.

6. Check and debug the gear drive or chain drive to meet the mechanical transmission requirements.

7. Perform safety checks on motors and appliances. Touch the motor power switch, the motor and transmission parts should be free of jamming, and make sure that the spindle is turning correctly (the blade should be pointed forwards when the blade rotates).

8. Start the motor to make the equipment run at no load, the operation should be smooth, and no abnormal noise should appear. For speed control devices, the speed should be adjusted within the adjustable range. When accelerating, the speed should be slow to check whether the speed regulation characteristics meet the requirements. No more than 30 minutes of no-load operation.

9. Gradually heat or cool, observe the operation, and make the heat source or cold source reach the use parameters. Equipment with cooling protection must open the cooling water valve before steaming. Gradually add materials, observe and check the dry condition of the materials, and continuously adjust the feeding amount, heat (cold) source quantity, discharge amount and rotation speed according to the needs, and then put into normal operation after reaching the design requirements.
