Electromagnetic Wet Filter

Electromagnetic Filters: Powerful Magnetic Separation Technology

Electromagnetic filters provide highly effective removal of fine iron and paramagnetic minerals from ceramic slips, glazes, and industrial mineral slurries. Key features include:

• Generate strong magnetic fields up to 10,000 Gauss for superior separation efficiency
• Remove problematic magnetic particles as small as 0-500 microns
• Automated cleaning cycles for continuous processing
• Available in 3,500 to 10,000 Gauss models for different applications

How Electromagnetic Filters Work

• Electromagnetic coil creates intense magnetic field in stainless steel matrix
• Slurry pumped through matrix, magnetic particles attracted and captured
• Periodic cleaning cycles flush out captured particles
• Can be set up in pairs for non-stop operation

Key Benefits

• More effective than permanent magnetic separators
• Removes very fine iron and paramagnetic minerals
• Improves purity of ceramic materials and industrial minerals
• Automated operation with programmable controls

Common Applications

• Cleaning ceramic glazes and slips
• Purifying mineral slurries like silica sand, feldspar, kaolin, etc.
• Removing contaminants from ball clay, calcium carbonate, talc

For industries requiring high-purity materials, electromagnetic filters offer powerful magnetic separation capabilities to remove even the finest magnetic contaminants. Their adjustable field strength and automated operation make them ideal for a wide range of ceramic and mineral processing applications.

High Magnetic Field Strength: Offers a range of background magnetic field strengths from 3,500 to 10,000 gauss for effective separation of fine iron and paramagnetic minerals from liquids and slurries.

Applications: Used to remove fine iron and paramagnetic minerals from non-metallic mineral slurries.

Efficient Separation: Higher separation efficiency than permanent magnetic separators by generating significant background magnetic field strength, and a high-magnetic field gradient on the matrix surface.

Back Flush Cleaning: Automated back flush cleaning cycle to clean captured contaminants off the matrix. Cycle times can be adjusted via the HMI to suit application needs.

Energy Efficiency: Utilizes highly efficient computer-designed coils paired with an air-over oil heat exchange to maintain optimal operating temperature.

Easy Maintenance: Includes a removable job crane for easy removal of the top pole and matrix assembly for maintenance and cleanings. This minimizes downtime and needs for additional infrastructure.

Controlled Operation: Can be fully automated using a control system with a Siemens S7-1200 PLC and HMI for managing cleaning frequency and parameters.

Valve Configurations: Available in 4-valve to 8-valve configurations to suit different applications.

Testing Facilities: Bunting offers controlled tests on laboratory-sized filters to confirm separation capabilities.
