Rubber Joints

PROTEM provides rubber joints made of soft material for the connection of screw conveyors with the cement scale and the scale with the mixer.
Bad quality or under-maintenanced rubber joints are the No 1 cause of errors on cement weighing. This is happening when the joint is made of a material which hardens due to the exposure at the sun and cement itself. This results in having significant forces applied in the area affecting the weighing accuracy.

Following standard sizes of rubber joints are available, covering almost all screw sizes as well as the butterfly valves of the cement scales:

  • Diameter Φ 150 mm, length 750 mm
  • Diameter Φ 170 mm, length 750 mm
  • Diameter Φ 200 mm, length 750 mm
  • Diameter Φ 220 mm, length 750 mm
  • Diameter Φ 250 mm, length 750 mm
  • Diameter Φ 280 mm, length 750 mm
  • Diameter Φ 300 mm, length 750 mm
  • Diameter Φ 325 mm, length 750 mm

On request, we can also manufacture other sizes.
