Beltless Magnetic Conveyors

  1. Wear and impact resistant slider bed
    • Minimum 12-gauge stainless steel slider bed (7-gauge for over 18” wide or manganese option)
  2. Optimized for minimal magnetic drag
    • Magnets enclosed in UHMW wrapper, internal stainless magnet supports and welded stainless motor mount
  3. Automatic chain tensioning
    • Internal take-up maintains tension for life of unit and is enclosed to keep debris out of moving parts
  4. Best in class track system W
    • Welded structural steel angle and stainless in convex and concave (high wear areas) – No plastic track or laminated light gauge steel channel
  5. American made drive packages

—————-

  • Conveyor frames and chain guides are laser cut to precise tolerances
  • Conveyor frames are 11 ga. minimum
  • Slider beds are 12 ga. stainless steel and sealed liquid-tight
  • 7 ga. stainless steel slider beds on units 18″ wide and larger
  • 2″ tall side guides standard
  • Slider face attachment nuts and bolts are on 1-1/2″ spacing for radius and 4″ spacing for straight sections
  • Internal magnets are enclosed in specially formed UHMW cartridges for integrity and reduced friction
  • Powerful Ceramic 8 magnet material
  • Internal oil bath lubricates all internal moving components for quiet, trouble-free operation
  • Self-adjusting chain tensioning system standard
  • 1/2 HP 230/460V 3-phase motor with gear reducer and torque limiter

    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.

    Beltless Conveyor Options to Consider

    • BLM Series:
      • MPI offers three series of magnetic conveyors. Each larger series has a larger body to accommodate larger magnetic cartridges and heavier duty internal chain designed to handle more difficult scrap or higher scrap rate capacities. MPI will help you select the correct duty for your application.
        • 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 or 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.
