IFAT 2018 – Recovering more marketable material from waste

The pre-shredder designed specifically for preliminary shredding

The pre-shredder (VSR) is particularly well-suited for the pre-shredding of large or voluminous materials such as household, industrial, commercial and bulky waste.

BHS-Sonthofen will present the pre-shredder of type VRS 1215 at IFAT 2018. It is used for the pre-shredding of domestic and commercial waste, white goods, electronic waste and building materials. For the first time, BHS optionally supplies the machine with either a tearing table or a counter-crossbeam. This allows customers to adapt it to a wide range of feed materials and desired granulation of the shredded material – which is a key prerequisite for cleanly separating the material by type. BHS will also be presenting a Rotorshredder of type RS 2018, which the company has developed specifically for shredding electronic waste.

The pre-shredders of type VSR are low-speed, high-torque twin-shaft crushers. Due to the rotor shafts’ relatively large diameter and the special blade geometry, the machine is particularly well-suited for the tearing pre-shredding of large or voluminous materials such as household, industrial, commercial and bulky waste.

The tearing table is used when processing bulky feed material. The new counter-crossbeam is ideal for the pre-shredding of materials such as electronic waste. In this application, it is particularly important to cleanly break apart solid components – for example, steel printer shafts – without damaging batteries and capacitors.

BHS will also be presenting the Rotorshredder of type RS 2018 with new discharge doors developed specifically for shredding electronic waste. Thanks to the doors’ arrangement, material that has already been separated is prevented from once again mixing with other components. As a result, the machine delivers cleanly separated materials for efficient downstream processing.

We look forward to seeing you at IFAT 2018 in Munich, Germany at the BHS booth 351/450 in Hall B4!

Design of the Pre-Shredder

The feed material is captured by the two rotating shafts, which change their direction of rotation at regular intervals. The tearing tools (red) on the shaft act in both directions during rotation.

Rotorshredder with two large doors

Two large doors provide easy maintenance access to the interior of the Rotorshredder (RS).

Crushing tools of the Rotorshredder

The shredding tools of the Rotorshredder of type RS consist of several rugged hammers, which are flexibly mounted on a high-speed vertical shaft.
