OVERVIEW
WHO USES IT, WHAT IT DOES, AND WHY IT PAYS
SUMMARY
The SZLH pellet mill employs a high-precision, imported-brand gearbox to deliver efficient, reliable torque to the die. Fuzzy-logic control optimizes pelleting parameters, while an optimized feeder size/angle ensures uniform feed and stable load. Unique tools simplify die changing and roller adjustment to shorten maintenance windows. Optional oil-level monitoring warns the operator before gearbox lubrication drops. Magnetic iron removal protects gears; a reclaimer safety baffle prevents material/steam recoil; a safety-pin guard keeps fragments secure if a pin breaks.
APPLICATIONS & MATERIALS
Animal feed (livestock, poultry), Aqua feed. Suited to free-flowing, pelletizable formulas after proper conditioning and moisture/temperature control.

FAQ
How do I size the pellet mill?
Use target t/h at the chosen die diameter and recipe; select die size and motor from the model table, then confirm with conditioner capacity and compression ratio.
How fast is a die change?
Dedicated tooling and accessible layout shorten die/roller service, reducing downtime compared with conventional designs.
What protections are built in?
Door and overload protections, guarding, iron-removal for the gearbox and optional oil-level monitoring; gearbox cooling on most models.
Can I run different pellet diameters?
Yes—specify dies and compression ratios suited to your species/formulas; rollers and feeders are adjustable.
What are the utilities?
Three-phase power (50/60 Hz), steam for conditioning, compressed air for pneumatics
