The material is loaded into the bunker of H2Pro’s Bag Opener by wheel loader, excavator, or crane. The walking floor in the bunker transports the material, monitored by a level sensor to the bag opener module. The bags are drawn in by the opening unit and opened and emptied between the teeth of the drum and the hydraulically pretensioned combs.
The material mixture drops out under the machine and falls to the arranged conveyor belt below.
Impurities are drawn in and pressed against the combs by the rotary movement of the drum. If the preload force is exceeded, one or more segments open. The impurities can escape and the combs go back to the starting position.
