ZBS Lump and Purge Shredder

Lump and Purge Shredder Description

ZERMA's ZBS Series is a single-shaft plastics lump and purge shredder with a tangential infeed eliminates the need for a hydraulic feeding system. Its compact and maneuverable design and ‘plug and play’ controls give this shredder total flexibility and ease of use. Like the ZSS, ZIS, and ZHS series shredders, the ZBS is driven by an oversized gearmotor and equipped with outboard bearings. It has a 310 mm diameter flat E-type rotor using the proven ZERMA knife holder and knife design in 600 mm or 850 mm widths. The user-friendly design allows for simple and efficient cleaning and maintenance. The ZBS lump shredders’ low rotor speed of 60 rpm and compact design makes it possible to shred lumps at a relatively low noise level. The shredder can be manually or conveyor fed with material discharge by conveyor or into a dropbox.

Lump and Purge Shredder Plastics Applications

The ZBS plastic lump and purge shredders are designed for in-house recycling of small lumps and purges from injection and blow molding processes. The typical input materials are small and medium-sized cakes such as head waste. The plastic material can be shredded to reduce its volume or processed further by a granulator and immediately reintroduced into the production process. The shredder also can destroy sensitive products or recycle small batches of low-volume products to avoid contamination of the main product line.

Concave Rotor Knife

The concave ground square knives produce high-quality output and can be rotated after a side is worn out.

E-type Rotor

The flat E-type rotor has specially-machined pockets to hold and secure the knives. Optional weld on hard facing is available for abrasive applications.

Lumps & Purgings

The ZBS shredders can easily process lumps and purgings of up to 400 mm diameter due to its aggressive tangential infeed that doesn’t need a hydraulic pusher.
