Removal of metal contamination from glass cullet is usually done in two steps: first - removal of ferrous tramp metal and then taking out nonferrous contamination. Ferrous metals are easily extracted from the product flow by traditional suspended (SMPR & SMPA models) or pulley magnets (SMB). If separation is necessary not on the conveyer, but in some gravity flow, plate separators (PSM) with removable protective covers can be used, or self-cleaning magnetic drums (SMBM or BSM) with removable enforced sidewalls.

Removal of nonferrous contamination is performed by SMVT magnetic separators, where eddy current, generated by a magnetic rotor, repels nonferrous metals from the rotor, while allowing the separation product to continue in the flow. SMVT eddy current separators have a number of adjustable units and construction elements for adjusting separation performance to the customer's requirements.

Recommendations:

• Removal of ferrous tramp metals from the product flow is required before its feeding into the SMVT separator.

Magnetic separators , designed and produced by Research & Production company «Erga», surpass electromagnetic and ferrite - based analogues in both technical and economical aspects . All the types of produced equipment have already proved to be effective at many glass-producing works in Russia and CIS.

Comprehensive engineering approach, used by «Erga» LLC in solving magnetic separation problems, includes:

• Studying specific technological processes at the customer's enterprise.
• Organizing product sampling in the technical laboratory. Defining characteristics, necessary for achieving optimal industrial separation performance.
• Design and optimisation of equipment for simple installation into an existing technological chain.
• Production of permanent rare-earth magnets and magnetic separators, based on Nd-Fe-B & Sm-Co alloys.
• Installation and start-and-adjustment works by customer's request. - Warranty repairs.
