Plastic extruder equipment should be situated in a well-ventilated area to ensure proper heat dissipation from the motor, thereby extending its service life; the machine must also be properly grounded.
Regularly inspect the screws securing the cutting blades. After one hour of operation with a brand-new machine, use appropriate tools to tighten the screws for both the rotating and stationary blades to ensure a secure connection between the blades and their mounts. Lubricating oil should be applied to the bearings at regular intervals to maintain proper lubrication. To ensure the sharpness of the cutting edges, the blades should be inspected frequently; maintaining their sharpness helps prevent unnecessary damage to other components caused by dull or chipped blades. Additionally, regularly check the drive belts for slackness and tighten them promptly if necessary.
Restarting-Before restarting the machine, clear any residual shredded material from the crushing chamber to minimize starting resistance. Periodically open the inertia wheel cover and pulley cover to clear the dust discharge port located beneath the flange plate, as fine dust from the crushing chamber can otherwise enter the shaft bearings.
Component Replacement-When replacing the cutting blades, the clearance between the rotating blade and the stationary blade should be set as follows: for crushers with a power output of 20 HP or higher, a gap of 0.8 mm is recommended; for crushers under 20 HP, a gap of 0.5 mm is recommended. If the material being recycled is particularly thin, the gap may be adjusted slightly wider.
