• Technical Specifications
• Capacity
• Drawings
• Generates background magnetic fields of up to 10,000 Gauss, amplified 3–4 times on the matrix for higher separation efficiency
• Removes problematic magnetic particles as small as 0–500 microns
• Automated cleaning cycles for continuous processing
• An electromagnetic coil induces a strong magnetic field in the matrix
• Slurry is pumped through the matrix, and magnetic particles are attracted and captured
• Regular cleaning cycles flush out trapped particles
• Can be set up in pairs for continuous operation
• More effective than permanent magnetic separators
• Removes very fine iron and paramagnetic minerals
• Improves the purity of ceramic materials and industrial minerals
• Automated operation with programmable controls
• Cleaning ceramic glazes and slips
• Purifying mineral slurries such as silica sand, feldspar, kaolin, etc.
• Removing contaminants from ball clay, calcium carbonate, and talc

Includes a removable jib crane for easy removal of the top pole and matrix assembly for maintenance and cleaning.

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

For industries that require 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 a significant background magnetic field strength and a high magnetic field gradient on the matrix surface.

Back Flush Cleaning: An automated back flush cleaning cycle designed to remove trapped contaminants from the matrix. Cycle times can be adjusted via the HMI to meet application requirements.

Energy Efficiency: Uses highly efficient, computer-designed coils combined with a water-over-oil heat exchanger to maintain optimal operating temperature.

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

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

Testing Facilities: Bunting conducts controlled tests on laboratory-scale filters to verify their separation capabilities.
