Feeding /­ Dosing /­ Preparation

Box Feeders

Storing, buffering, feeding, dosing

Box feeders are firmly established in the recycling industry, in the extrusion of solid or hollow strands, in the brick industry and in the feeding of biogas plants.
On the one hand, they act as storage or buffers; on the other hand, they transfer the material to the next machine for further processing.
Thanks to the infinitely variable speed of the belt and a height-adjustable pusher at the material discharge, the desired material throughput can be optimally controlled and metered. In addition, the reel shaft ensures uniform material discharge.

Box Feeders KBR

  • Recycling industry
  • Brick and tile industry
  • Feeding of biogas plants

The KEMA box feeders are available in various box widths and axial distances.

Box width: 1000, 1250, 1500, 2000 Millimeter
Axial distances: 4, 6, 8, 10, 12 Meter

Circular Feeders

Feeding, portioning

Circular feeders are integrated into existing conveyor lines as material buffers. They are used for feeding and portioning ceramic masses as slugs, filter cakes or similar.
ECT-KEMA Circular Feeder 1500

Circular Feeder RB 1500

  • Integration into existing conveyor lines as material buffer
  • Feeding and portioning of ceramic masses as slugs, filter cakes or similar
  • Vessel diameter: 1500 mm
  • Screen height: 750 mm
  • Dimensions: (L/­­­B/­­­H): 2300 x 1330 x 2150 mm


Rotary Screen Feeder

Aufbereiten & Homogenisieren

In der Tonindustrie erzielt der Siebrundbeschicker beste Aufbereitungsergebnisse. Das Durchstreichen des Tones durch die Siebe garantiert die exzellente Homogenisierung der Masse. Die hierbei entstehenden Tonnudeln werden von dem robusten und ringförmigen Sammelteller aufgenommen und mittels eines Abstreifarmes an die nachfolgende Maschine weitergegeben.

Rotary Screen Feeder SRB 1900

  • Addition of aggregates
  • Addition of water and steam
  • Homogenization of materials with slightly different moisture content
  • Storing and continuous feeding between preparation and shaping
  • Vessel diameter: 1900 mm
  • Screen height: 500 mm
  • Dimensions: (L/­­­B/­­­H): 3650 x 3400 x 3350 mm


Dosing Strainers

The right quantity at any time

Dosing trainers ensure the continuous supply of the compounds to be extruded. Depending on the requirements, feeding takes place as volumetric feeding with and without consideration of the degree of filling, as gravimetric feeding by means of a downstream belt weigher, or as feeding according to the differential weighing principle.

This makes the technically and economically problematic buffering of slugs or bulk material between discontinuously operating mixers/­kneaders and continuously operating vacuum units a thing of the past.
