SLG Continuous Powder Surface Modifier Standardized Operation Procedure

To ensure safe and efficient operation of the equipment, this operating manual divides the entire production process into four standardized phases. Operators must strictly follow the following steps:

I. Production Preparation Phase

1. Equipment Condition Inspection

• Thoroughly inspect core components such as the main unit, feeder, metering pump, and fan.
• Focus on inspecting the wear of the rotor blades and stator.
• Verify that the air duct system (inlet/discharge) is unobstructed and free of blockage.
• Verify the accuracy of the thermometer and temperature control system.

1. Raw Material Pretreatment

• Accurately weigh the powder raw materials and surface modifier according to the recipe.
• Raw materials must be dried. Clean and sieve to remove lumps.
  -Preheat the solid modifier to a molten state. Dilute the liquid modifier as needed.

1. Safety Precautions
   -Operators must wear dust masks, goggles, and protective gloves.
   -Clean the work area and remove all flammable items.

II. Startup Procedures

1. System Startup Sequence
   ① First, start the fan and air supply system (establish air circulation).
   ② Start the main engine motor at no load (run for 1-2 minutes).
   ③ After confirming stable operation, start the feeder (feed at a constant speed).
   ④ Simultaneously start the metering pump (add modifier according to the set ratio).

III. Modification Operation Control

1. Operation Parameter Management
   -Maintain the feeder. Maintain a stable feed rate (recommended to be controlled within 80-95% of rated capacity)

• Monitor operating temperature (usually maintained between 50-80°C)
• Take samples regularly to test the modification effect

1. Real-time Adjustment Strategy

• Fine-tune the modifier flow rate based on test results (within ±5%)
• Adjust rotor speed via a frequency converter (affects shear strength)
• Observe the discharge state (ideally, the finished product should be dispersed and flowing)

IV. Shutdown and Cleaning Procedures

1. Standard Shutdown Procedure
   ① First, stop the feeder and metering pump.
   ② Allow the equipment to idle for 1-2 minutes (to purge any residual material).
   ③ Shut down the main motor and fan system in sequence.
2. Equipment Maintenance

• Use specialized tools to clean the internal cavity (compressed air + vacuum cleaner)
• Check the rotor/stator clearance and record wear
• Lubricate and maintain bearing components
• Completely record production data for the shift (including notes on any abnormalities)

1. Must adhere to the startup sequence of “fan → generator → material”
2. Strictly follow the shutdown procedure of “material → generator → fan”
3. Maintain stable parameters during operation (fluctuation no more than ±5%)
4. Samples must be retained from each batch and tested for coverage

Note: This procedure is a standardized operating guide. Modifications to operating parameters or omissions of steps are prohibited without the approval of the equipment management department. New operators must complete three full production cycles under supervision before operating independently.
