Beltless Magnetic Conveyors

MPI Beltless Magnetic Conveyors

MPI’s Beltless Magnetic Conveyors (BLM) are designed to provide positive control of ferrous metal materials. BLM series conveyors are available in three standard models in a wide range of configurations engineered specifically for your needs. Typical materials conveyed include metal, stampings, turnings, chips, fasteners and scrap.

BLM conveyors are offered with many design options and can also be supplied with other ancillary components, such as feeders and hoppers to provide a complete material handling system. Conveyors are available in shapes such as dogleg, dogleg with extended discharge, horizontal straight and incline straight.

Providing effective control of ferrous objects on high speed horizontal and inclined to vertical conveyor belts, MPI’s Magnetic Belt Conveyors are available in a wide range of styles for a variety of belting designs such as fabric, table top and stainless steel mesh. Magnetic Belted Conveyors are offered with many design options and can also be supplied with other ancillary components such as feeders, hoppers, etc. to provide a complete material handling system.

How Beltless magnetic Conveyors Work

How beltless magnetic conveyors work
Powerful permanent magnets are conveyed below a nonmagnetic stainless steel slider bed to move and convey ferrous metal objects. The liquid-tight, sealed conveyor housing can be completely submerged in machine reservoir tanks and the internal self-adjusting take-up system eliminates the need for maintenance. No external moving components make the beltless magnetic conveyor the safest way to convey ferrous metal parts and scrap.

MPI BLM Series: Models & Specifications

Three lengths of mpi blm conveyors
  • BLM conveyors are available in THREE (3) standard models:
    • 600 Series – 6.5″ body depth
    • 800 Series – 8.5″ body depth
    • 1200 Series – 13.875″ body depth
  • Shape Configuration:
    • Horizontal straight
    • Incline straight nose over
    • Dogleg horizontal/continuous radius discharge
    • Dogleg nose over
    • Incline straight horizontal/continuous radius discharge
  • Discharge Design:
    • Horizontal (standard)
    • Nose over – recommended for small scrap and compact designs
    • Continuous radius – recommended for smooth scrap transfer of long pieces
  • Infeed Length:
    • Minimum infeed length is 30″ to as long as required for customer application
  • Angle of Incline:
    • 15°, 30°, 45°, 60°, 75°, 90°
    • Custom
  • Discharge Length: The minimum discharge length depends on the discharge design selected. The discharge lengths can be made as long as required for the application.
    • Minimum length for nose over-discharge design is body width, the shortest design available
    • Minimum length for horizontal discharge design is 22″
    • Minimum length for continuous radius discharge design depends on the angle of incline, at least 22″
  • Infeed Height: Floor installation is standard. This will result in the infeed height being the body depth specified by the series selected. Legs can be added for raised infeed heights.
    • Body depth (standard)
    • As specified for the application (legs added)
  • Discharge Height:
    • No standard – as specified for the application
  • Overall Length:
    • Calculated based on configured dimensions and options specified above
  • Slider Bed Width: Minimum widths are based on series selected. Standard widths are available in increments of 2″ from the minimum to a maximum of 24”. Overall body width of the conveyor is the slider bed width plus 4″.
    • 600 series – minimum 6″
    • 800 series – minimum 8″
    • 1200 series – minimum 12″
    • Special – compact design where overall body width of the conveyor is the slider bed width plus 2″
  • Slider Bed Material:
    • Under 18″ wide – 12 gauge stainless (standard)
    • 18″ wide and larger – 7 gauge stainless (standard)
    • 7 gauge manganese impact plate for specified length
    • 7 gauge manganese impact plate through infeed
    • 7 gauge manganese impact plate whole length
    • 16 gauge laminated rigidized material on top of standard slider bed to reduce part friction
    • 7 gauge manganese impact plate dimpled to simulate rigidized material
  • Magnet Material: Standard magnets are ceramic and will work for most applications. Testing will determine if rare earth magnets are required to achieve required rate.
    • Ceramic (standard)
    • Ceramic with REN rare earth sweepers to break potential surges
    • High capacity REN rare earth with stainless steel body to reduce drag
  • Magnet Centers: Magnet centers are based on the maximum part length. For proper function of BLM the general rule is the centers will be 1.5 times the parts/scrap maximum length.
    • 600 series – increments of 5″ centers
    • 800 series – increments of 6″ centers
    • 1200 series – increments of 8″ centers
