Main Parts Overview

Functional Description Form

1 Feeding hopper
2 Charging screw
3 Pre-charger cylinder
4 Pre-charger
5 Mould
6 Press piston
7 Main press cylinder
8 Ejectors

  • The charging screw (2) feeds the material which is stored in the hopper (1) into the pre-charger (4). The running time of the screw is calculated by a PLC control unit.
  • After filling the pre-charger cylinder (3) pre-compresses the material in the pre-charger chamber (4).
  • The main piston (6) pushes the pre-compressed material into one of the two press chambers in the die (5) and compresses the material into a dense block. During this process the ejectors (8), which are fixed parallel to the main press piston, push out the ready briquette from the second press chamber through ejector holes in the front plate.
  • The pre-charger cylinder (3) moves upward again. Then the feeding screw starts with the next charge.
  • The press mould changes.
  • The run continues.

Functional Description Shutter/Slider

1   Feeding hopper
2   Charging screw
3   Agitator
4   Pre-charger
5   Press mould
6   Press piston
7   Main press cylinder
8   Shutter / Slider
9   Outlet chute
10 Emulsion pan

  • The charging screw (2) feeds the material which is stored in the hopper (1) into the pre-charger (4). The running time of the screw is calculated by a PLC Control unit. (Attention on machines without pre-charger – here the material is fed directly into the press chamber (5) and the course goes further with No. 3!)
  • After filling, the pre-charger (4) precompresses the material in the pre-charger chamber (5).
  • The press piston (6) pushes the pre-compressed material against a shutter/slider (8) and compresses the material into a dense block. Now the press piston (6) moves slightly back and the shutter/slider (8) opens. Then the press piston (6) pushes out the briquette through the hole in the front plate. The press piston (6) moves back into its end position.
  • The pre-charger (4) moves upward again (not on machines without pre-charger).
  • Then the feeding screw (2) starts the next run.
