INTENDED USE

Grate magnets are intended for separation of smal iron particles from free-falling loose materials. The SM and SMA separators protects process machines against mechanical damage and a prevents consumers from eating a dangerous metal pieces. High intensity and density of the magnetic field allow to capture magnetic materials of very small weight and surface: fine wires, filings, rust, iron oxides and other particles with weak magnetic properties.

TYPES OF GRATE MAGNETS

Grate magnet type SM with manual cleaning
SM type sepaartor has a dustproof casing made of acid resistant stainless steel (food industry version). 1 ÷ 4 rows of magnetic bars are installed inside the casing in special stacks. Each stack has stable guides providing free movement of magnetic bars. Bars in subsequent stacks are arranged alternately generating dense magnetic field. Magnetic bars feature cores made of high-power NdFeB magnets. Neodymium cores are secured against direct contact with the falling material by abrasion resistant light wall tubes made of non-magnetic alloy steel.

Grate magnet type SMA with automatic cleaning
SMA type separator has a dustproof casing made of acid resistant stainless steel (food industry version). Three rows of magnetic bars are installed inside the casing and forming a tight barrier for ferrous metals. Each bar consists of a mobile magnetic core and non-magnetic alloy steel protective tube. Magnetic cores are made of high-power NdFeB magnets and are moved inside the protective tubes with compressed air. Core movement is synchronized by PLC controlling operation of solenoid valve. During the cleaning phase, magnets are blown through to the cleaning chamber using compressed air. Captured iron particles move through the surface of protective tubes following the magnets up to the partition, where they fall to the metal chute due to losse of magnetic field.

Type SMA ... EX automatic grate magnet is designed for operation in explosive atmosphere. Device is ATEX certified.
