• Hopper volume sufficient for residue of a press charge
  • Fast discharge of the hopper
  • Four sizes for 1–4 presses

The Delta collecting screw conveyor is designed for removal of the press residue from the Bucher HPX/HPS presses. The hopper volume is sufficient to take the entire residue of a press charge to allow a fast dumping.

The V-shaped hopper is installed under the steel frame of the Bucher HPX/HPS press. The press dumps the residue into the hopper. It is then conveyed by a horizontal auger to the intended storage site or to the next transportation element. For safety reasons the hopper is equipped with protective bars below the dumping outlet of the press; the remaining part of the hopper is covered with removable lids. The unit is driven by a gear motor and a chain drive. Construction of the screw in stainless steel in accordance with DIN 1.4301 (AISI 304) or painted mild steel.
