Bar-Type Magnetic Separators
Engineered for high-efficiency ferrous contamination removal from powders, granules, and liquids. Surface magnetic strengths of certain specifications up to 16,000 Gs.
What Is a Bar-Type Magnetic Separator?
A Bar-Type Magnetic Separator (also called magnetic bar, rod, grate, or filter) consists of a stainless-steel tube encasing high-intensity permanent magnets. As material passes across the surface, ferrous contaminants—including iron filings, metal dust, and weakly magnetic stainless-steel particles—are captured securely.

Why Choose Magnetic Bar Separation?
High-Efficiency Removal
Captures down to 30 microns, including fine dust and weakly magnetic stainless steel.
Universal Compatibility
Works with powders, granules, liquids, slurries, and viscous materials.
Low-Maintenance
No electricity needed; permanent magnets maintain strength for over 10 years.
Equipment Protection
Prevents damage to downstream mills, mixers, extruders, and pumps.
Compliance & Purity
Essential for food safety, pharmaceutical standards, and chemical purity.
Highly Customizable
Length, diameter, Gauss level, and installation tailored to needs.
Types of Bar-Type Magnetic Separators
Diverse configurations to fit any production line.
Standard Magnetic Bars
Installed in hoppers or chutes. Cost-effective manual cleaning solution for powders.
Magnetic Grate / Grid
Combination of multiple bars for gravity-fed systems. Ideal for grains and plastic pellets.
Magnetic Drawer
Easy pull-and-clean design. Preferred for food & pharmaceutical hygiene applications.
Rotary Magnetic Grate
Bars rotate to prevent "bridging" and clogging in sticky, cohesive, or poor-flow powders.
Liquid / Slurry Filter
Bars inside liquid housings to capture metal in chemical, battery, and mineral slurries.
Automatic Self-Cleaning
For continuous production lines, heavy contamination, or high-flow automated systems.
