Discharge of paper or film shreds in the disposal facility

How do stationary compactors for waste disposal of plastic or paper cuttings work?

Suction pipes are used, for example, to transport punching or cutting waste from a printing press via a pipe system to a waste disposal facility. The same applies to edge trim suction in plastic film production. The material waste is compressed in the stationary compactor and then transported to the transport container. The full container is transported away by truck.

What problems occur when disposing of electrostatically charged materials?

Due to the contact and separation, electrostatic charging of the substrates takes place in the production machines and in the pipe system. The charged material adheres to the side walls of the chute and clogs the system. The material also covers sensors that check the fill level of the system. This leads to malfunctions of the system, which can result in a machine stop.

Our solution

Suitable discharge bars with additional air duct are mounted in the best possible position in the drop chute.

blueBAR R50

The robust all-rounder bar The VARIO discharge bar blueBAR R50 creates a significantly higher active discharge capacity than most discharge techniques. The isolated ground conductor enhances the E-field at the active tips, contributing to increased production and velocity of charge carriers. Thus, significantly more positive ions and free negative electrons are available than with conventional bars. At the same time, the bars have a high passive discharge capacity. The resistance-decoupled tips ensure good discharge performance and make the bar absolutely short-circuit and touch-proof.
