Vibrating Feeders Series ML

Used to transport and dispense any type of bulk material.

Electromechanical drive powered by two electrical vibrators, which are usually installed below the hopper or pre-stock tunnel to feed, transport, extract and dispense bulk products.They are fitted with a static hopper spout to prevent the material from gravitating on the tray. The hopper spout measurements are included in the hopper installation plan.The hopper spout can be ordered with different blade or bar closures, load guides and airtight covers with elastic seals.Shutdown flow can be adjusted, modifying the mass eccentricity of the motor vibrators, which are equipped with a continuous scale dial. When the equipment is loaded, this adjustment is carried out using latest generation frequency variators, which can incorporate a braking chopper to halt feeding immediately. By combining both adjustment options it is possible to achieve a flow range of 0 – 100%.Low maintenance (periodic lubrication of the motor vibrator bearings). CE Marking. See video here.
Free standing or mounted on springs, with different types of insulation, depending on the application and surroundings:

  • Compression steel springs
  • Tensile steel springs
  • Rubber anti-vibration protections
  • AG type articulated mounts

In all cases, insulation is optimised, reducing as much as possible any transmissions and noise caused by the vibrations.

Possibility of fitting linings and coatings in different wear resistant and non-slip materials, such as rubber, wear resistant steel, stainless steel, or Teflon, polyurethane and polycarbonate coatings, etc.
The trays may be made of different types of steel, though the standard is carbon steel A42b. Complete machines or the parts in contact with the material may be manufactured in stainless steel, wear resistant steel, etc., on demand.
* Features coated. Wear plate fixed with screws DIN 7991 (countersunk Allen). It is provided with wear plate on bottom and sides.
** Data Metric Tons calculated for a slope of 10º and a density of 1.6 t / m3 in dry sand.
