Impact shredder / crusher for plastic Grindex-7

Grindex-7 plastic shredder is an industrial impact shredder that enables the reduction of a wide range of materials—not only plastics, but also wood and waste paper. Thanks to a powerful 7.5 kW motor and robust construction, the machine delivers high efficiency while remaining relatively compact.

The device is equipped with a rotor with 12 moving knives and 2 fixed knives, which enables effective and consistent shredding of materials of varying hardness. A variable output fraction is also possible by using interchangeable screens with a maximum aperture size of up to 8 mm.

Shredder Grindex-7 works great as a plastic shredder for materials such as LDPE, PP, PVC and PE, but it can also be used as a wood waste shredder and a glass shredder.

Advantages of the Grindex-7 shredder:

• Universal shredding – plastics, wood, paper, production waste
• Stable operation – belt drive and rotor speed of 650 rpm
• Interchangeable screens – adjustable output fraction
• Compact dimensions – easy transport
• Easy access to the working chamber – quick maintenance
