What procedures should be taken to guarantee stability and safety when installing an extruded feed pellet mill for the first time?

 

 

Industrial extruders (such as plastic and feed extruders) are large in size and have many parts. If the initial installation is not done correctly, it may not only cause abnormal noises and insufficient production capacity, but also lead to safety accidents (such as motor short circuits and barrel misalignment) due to an unstable base or incorrect wiring. Many factories need to repeatedly debug for 1-2 weeks before they can start production normally due to improper installation, which seriously delays the construction period.

 

 

1. Site and Foundation Preparation
Clean the installation area (the area should be 1.5 times larger than the equipment size to allow for operating space). Use a level to check the flatness of the ground (error ≤ 2mm/㎡). If it does not meet the standard, a concrete foundation needs to be poured (thickness ≥ 20cm, with pre-embedded anchor bolts).
After the foundation has cured for 7 days, hoist the extruder base onto the foundation and adjust the base level (use a level to check the barrel axis, horizontal error ≤ 0.1mm/m). Tighten the anchor bolts (torque as required by the instruction manual, such as 120-150N・m for M20 bolts).

 

2. Core Component Assembly

First, install the motor and gearbox: Align the gearbox flange with the barrel flange (coaxiality error ≤ 0.1mm), and tighten the connecting bolts; connect the motor output shaft and gearbox input shaft via a coupling, calibrating the coupling coaxiality (radial deviation ≤ 0.05mm, angular deviation ≤ 0.1°); Next, install the barrel and screw: avoid collisions during barrel hoisting, slowly push the screw into the barrel (apply high-temperature grease to reduce friction), ensuring the screw and barrel are coaxial; install the die head and heating coil (heating coil tightly against the barrel, wiring terminals secure, insulation resistance ≥ 1MΩ).

 

3. Auxiliary System and Circuit Connection

Feeding System Installation: Align the feeder outlet with the extruder inlet (deviation ≤ 5mm), and ensure stability with a fixed bracket; Connect the cooling system (connect the water chiller pipes to the barrel cooling chamber, and check for leaks); Circuit Connection: Connect the power supply lines (380V three-phase, ground wire reliably grounded) and control lines (motor, heating coil, and sensor lines are color-coded). Before powering on, use a multimeter to check the insulation resistance (≥ 0.5MΩ) to avoid short circuits.

 

4. Trial Run and Debugging: No-load test

Manually rotate the screw without jamming, start the motor and run it idle for 30 minutes (gradually increasing the speed from low to 50% of the rated speed), checking the bearing temperature (≤60℃) and any abnormal noises; Load test: Add raw materials (such as plastic granules, feed ingredients) according to process requirements, adjust the heating temperature (sectional temperature control of the barrel to the set value), and the screw speed, observing the quality of the extruded product (such as granule uniformity and plasticizing effect), and continue debugging until the standards are met.

 

 

 

1. Disassembly Process (Before Subsequent Maintenance)

Shutdown Preparation: Turn off the heating system and motor. Wait for the barrel temperature to drop below 50℃, then clean any residual material from the barrel (run dry material through the barrel for 10 minutes to drain). Disconnect the main power supply and hang a warning sign saying "Do Not Power On".

 

2. Auxiliary Component Disassembly: Remove the feeder, cooling pipes, and electrical wiring (mark the wiring locations for easy reinstallation). Remove the die head (unscrew the die head bolts after heating to avoid burns).

 

3.Core Component Disassembly: Loosen the bolts connecting the gearbox and barrel, and lift the gearbox and motor away. Remove the barrel fixing bolts and lift the barrel and screw together from the base (requires at least two people to avoid collisions). Further disassembly of the screw, bearings, and other components can be performed for maintenance later.
