BHS Rotary Shear The Rotary Shear is a low speed, high-torque, twin-shaft shredder. The machine is suitable for the shredding of bulky materials (e.g. domestic, commercial and bulky waste) or ductile input material (e.g. tires, cables, plastic film, paper, textiles) using cutting tools. It also reduces high-volume input materials and items with a large unit weight. At the same time, the Rotary Shear reliably achieves an extremely high shredding ratio.

FLEXIBLE MODULAR SYSTEM 5 www.bhs-sonthofen.com Targeted shredding results The first process step in the mechanical treatment of waste materials is to reduce and homogenize the particle size of the input material. The Rotary Shear reduces the input material to the desired particle size, at the same time ensuring a uniform bulk weight. The cutting tools can be refurbished multiple times. This makes for cost-effective exchange of a shear shaft assembly in the event of wear. Clean and consistent cut quailty The cutting tools are precision made and are manufactured with very tight tolerances....

The input material is fed into the machine through a large, central hopper. In addition to standard solutions, customerspecific hoppers are available. 2 The machine housing consists of an extremely robust, onepiece welded steel construction. This allows the machine to absorb extremely high forces without difficulty. 3   Rotor with cutting tools The input material is shredded between two counter-rotating rotor shafts which converge at the center. The special configuration of the cutting tools on the rotor shafts guarantees an excellent size-reduction performance. 4 The scrapers are attached...

Quick-change system The quick-change system for the shear shafts consists of a specially developed quick-action coupling between the shear shaft and gearbox, as well as the patented bearing shell bridge. The quick-action coupling is bolted in place, making it possible to exchange the shaft without dismantling the gearbox. The bearing shell bridge can be easily removed, followed by the shear shafts which are taken out from above.

Functional description Located in a robust housing, two counter-rotating rotor shafts converge at the center and take hold of the input material. Each shaft is equipped with a row of precisely manufactured cutting tools which mesh with each other like scissors. Gripper hooks are located at the tip of each cutting tool to insure the fast and reliable feeding of the material. The hydraulically operated push-in device can be used in individual cases if required. Scrapers are located behind the shafts to prevent material from adhering to the rotating cutting tools. The particle size of the...
