Material flow is the first check
Dry powder, granules, liquid, slurry and bridging materials require different contact and cleaning arrangements.
Drawer Magnet
A Drawer Magnet is a magnetic filtration arrangement for dry, gravity-fed, free-flowing material where ferromagnetic contamination needs to be captured before a downstream process. It is commonly considered around hoppers, chutes and enclosed feed points, but the equipment must be matched to actual flow behavior, available installation space and the planned cleaning procedure.

Product role
Overview and how it fits the process
A Drawer Magnet is a magnetic filtration arrangement for dry, gravity-fed, free-flowing material where ferromagnetic contamination needs to be captured before a downstream process. It is commonly considered around hoppers, chutes and enclosed feed points, but the equipment must be matched to actual flow behavior, available installation space and the planned cleaning procedure.
Material that bridges, compacts or carries significant moisture may require a different arrangement. For each project, the relevant inputs are material description, particle size, flow rate, temperature, interface dimensions, cleaning frequency and access. COWIN MAGNET can use those conditions to coordinate a suitable configuration discussion without assuming hygiene, temperature or magnetic-strength requirements.
Selection logic
Why this configuration needs site information
Magnetic contact needs space
The housing, tube or grid layout is reviewed around the available flow path so material can contact the magnetic surface without unnecessary restriction.
Cleaning access is designed in
A practical cleaning interval and safe access should be agreed before choosing a manual, drawer, rotary or pipeline configuration.
Contact materials are confirmed
For hygienic, corrosive or temperature-sensitive duties, the required contact material and operating limit must be confirmed against the real process.

Selection checklist
What to send for an initial configuration review
- Describe whether the material is free-flowing, sticky, bridging or abrasive.
- State the cleaning interval and whether shutdown is possible.
- For food or hygienic duties, confirm the actual compliance and contact-material requirements before ordering.
Important boundary
- The product should not be described as food-grade, sanitary or pressure-rated unless the specific material and documentation are verified.
- Flow restriction and bridging risk must be assessed for cohesive or viscous materials.

Questions to resolve before ordering
Which magnetic filter is suitable for dry powder or pellets?
The choice depends on free-flowing behavior, particle size, available headroom and cleaning access. Drawer, grid and bar arrangements are commonly reviewed for gravity-flow duties.
Can a magnetic filter replace a metal detector?
No. A magnetic filter captures ferromagnetic particles. A metal detector is a detection system and may identify other metals depending on its configuration.
What should be confirmed for liquid or slurry filtration?
Please provide flow rate, viscosity, temperature, solids content, line pressure, connection size, installation orientation and the expected contamination type.
Does every magnetic filter meet food-processing requirements?
No. Food-related contact material, finish, cleaning method and documentation must be confirmed for the actual process; they should not be assumed from a product family name.
