  • Built-in guiding plate for changing direction of rotation
  • PT 100 temperature sensor on bearings
  • Newly designed grinding bridge, which is split in demountable elements, so that the milltop will not need changing, every time the grinding bridges are changed
  • The grinding bridges are produced from processed steel sheet, and subseqently tempered
  • The mill has grinding bridges in both top and bottom for more effecient and optimum grinding
  • The bottom frame is reinforced to carry an engine as large as 455 kW

The FG1500 is suited for

  • Grain
  • Straw
  • Fishmeal

When constructing the conditioner type CLR the focus was on retention time and absorption of steam and liquid. The conditioner works well with pelletmills and extruder/feed expander. Furthermore our CLR is wide suited as single mixer where temperature and/or liquids are required.

Aspirations filters

For years GEMA-TEC A/S has produced a wide selection of process and aspiration filters in various types and sizes.

In the design and construction of Gema-tec filters special attention is on

  • low energy and compressed air consumption
  • minimum maintence
  • easy cleaning access
  • optimum use of filter capacity
  • customer required sizes and design

The GEMA-TEC A/S standard program include the following types of filters:

  • SF – a square filter with filter bag change from the side (SFS) or from the top (SFT). Type SF is only available with cone outlet
  • RF – a round filter with filter bag change from the side (RFS) or from the top (RFT). Type RF can be delivered with either cone outlet or scaber bottom
  • SP is a spotfilter for either horizontal (ex. on chainconveyor) or vertical mounting (ex. bucket elevator type SPV).

GEMA-TEC A/S is able to deliver complete filter solutions including filter, ventilator, piping, steel construction, mounting and start-up.
