Bag emptying stations / sack tip stations Flat Bottom Agitators, also known as Flat Bottom extractors or Bin Dischargers built of carbon steel or stainless steel AISI 304 – 316, are used under the hoppers and tanks to unload powders, ground materials and mixtures.

Bin discharger for hoppers and tanks

The application of these agitators becomes necessary and advantageous, especially when:

  • The stored product tends to pack and has poor fluency.
  • It is necessary to install it in a small space (thanks to its reduced overall dimensions).

The flat bottom extractor unloads laterally and rapidly by means of a special tapered rotor with a section having even resistance and special paddles with an anti-wear regulator.

This special shape of the rotor blade enables complete emptying of tank contents, leaving minimum residue and making this system quite popular in the food industry and all other applications in which cleanliness is paramount.

The diameters built are based on nominal diameters Φ 400 – Φ 600 – Φ 800 mm and upon request the diameters Φ 1000 and Φ 1200 mm with approximate rated power from 0.37kW to 4 kW.

The agitator paddle is moved by a gearmotor having a right-angled shaft and bevel wheels for maximum efficiency/output and quiet transmission.

Special care and attention have been given to the dust seals of the bearing, contained in the pulling assembly, made with puddening or special lip seals designed by GIMAT, that can be greased from the outside.

Equipment for explosive atmospheres (ATEX)

Upon request the Flat bottom extractors can be designed and built in conformity to ATEX Directive 94/9/CE for Zone 2-22 / Zone 1-21
