Self-Clean Magnetic Rotary Feeder

MPI Magnetic Rotary Feeders are installed in material handling systems where controlled feeding and contaminant removal are required. As materials enter the feeder, the rotary mechanism evenly distributes them across the magnetic field created by high-intensity magnetic tubes. The magnets attract and retain ferrous contaminants, ensuring only contaminant-free materials pass downstream. Cleaning processes can be manual or automated, depending on the model, ensuring consistent performance and minimal operator intervention. 

1. Material Flow & Magnetic Separation

Bulk materials enter the feeder through a spring-loaded control gate, ensuring a steady, regulated flow.

The powerful 400-series Ceramic 8 permanent plate magnet captures and holds ferrous contaminants as materials pass through the system.

2. Automated Self-Cleaning Process

The self-cleaning pneumatic system is activated at pre-set intervals or manually as needed.

Pneumatic cylinders automatically retract the magnetic core from the housing, releasing trapped metal contaminants.

As the magnet retracts, ferrous particles fall away and are collected in a designated discharge chute or collection tray, preventing recontamination.

3. Safety Cage for Operator Protection

The system is enclosed within a safety cage, preventing accidental exposure to moving parts and ensuring compliance with safety regulations.

The safety cage allows maintenance personnel to perform inspections without risk of injury, making it an operator-friendly design.

4. Damage Prevention & Continuous Flow

The spring-loaded control gate protects against damage by allowing large metal objects to pass safely before being captured.

Since the cleaning process is fully automated, there is no need to stop material flow, reducing downtime and improving efficiency.
