01

Insulated body

SG uses an insulated body to help limit noise transmission from the crushing process.

02

Sound-absorbing lining

Profiled sound-absorbing lining inside the enclosure further reduces the transmission of crushing noise.

Sound during operation depends on the material, feeding conditions, installation, and surrounding environment. Select the machine and installation around the site's actual noise-control needs.

Large Plastic Waste Applications

SG Silent Crusher supports centralized size reduction of large plastic chairs, crates or baskets, storage boxes, automotive bumpers, and similar bulky objects.

Assess the complete object dimensions and normal feeding orientation against the selected SG opening. Suitable material can be fed in its original form when the object and feeding arrangement fit, reducing manual pre-cutting.
