5. Operation
- Prepare Materials: Ensure all materials to be ground are completely dry. This machine is not suitable for wet or oily grains.
- Adjust Fineness: Turn the "Adjustment Fine" knob to select the desired fineness level, ranging from 50 to 150 mesh. Turning towards "Fine" will produce finer powder, while turning towards "Coarse" will result in a coarser grind.
- Load Materials: Carefully pour the dry materials into the Feed Inlet. Do not overfill.
- Start Grinding: Press the green "One Click Switch" to start the machine.
- Collection: Ground material will exit through the Discharge Port. Ensure a collection bag or container is in place. The machine has a production capacity of 30-60kg/h (66-130lb/h).
- Overload Protection: If the machine is overloaded, the overload protection feature will activate, stopping the motor to prevent damage. Reduce the amount of material and restart the machine.
- Stop Grinding: Press the green "One Click Switch" to stop the machine. For immediate shutdown, press the red "Emergency Stop Switch".

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your machine.
- Cleaning: After each use, unplug the machine. Disassemble the grinding chamber components (if applicable and safe to do so) and clean them thoroughly. The stainless steel construction allows for easy cleaning. Use a brush to remove any residual powder.
- Magnetic Device: Periodically clean the four high-intensity magnetic devices at the powder outlet to ensure they effectively absorb micro-amounts of wear metal material.
- Heat Dissipation Vents: Keep the heat dissipation vents clear of dust and debris to ensure proper motor cooling and prevent overheating.
- Grinding Discs: Inspect the grinding discs regularly for wear. Replace them if they show significant signs of wear to maintain grinding efficiency.
