BHS-Sonthofen introduces new universal pre-shredder for waste processing applications

The RAPAX pre-shredder
The BHS-Sonthofen RAPAX pre-shredder

BHS-Sonthofen's new RAPAX pre-shredder is suited for processing various metal fractions, commercial waste, industrial waste and construction waste. The flexible, smart control system also ensures efficient pre-shredding in every running direction.

Functional design elements make the RAPAX sturdier and easier to maintain, such as the intersecting struts on the funnel, which ensure greater stability. The surface, wall thickness and shape of the funnel are also sturdy and feature precise edges to avoid signs of wear and material build-up. The two planetary gears with belt drive are positioned side by side, as opposed to diagonally opposite, to save space.

The tearing table is located below the two shafts, which can be used along with the number of tools to determine the particle size.

Equipped for different applications

BHS offers the RAPAX pre-shredder in a number of different designs and sizes to ensure that it can optimally process a wide range of input materials, ranging from light scrap metal, electrical and electronic waste, industrial and commercial waste, to worn-out drywall and asphalt tiles. 

It is available as part of either the 15xx or 20xx series in three different sizes, with shaft lengths ranging between 1.2 and 3.2 metres. These allow the RAPAX to effectively shred extremely bulky input material such as construction waste or white goods. Two different tool geometries are available, depending on the design - either the highly serrated BAT shape version for a higher throughput in the case of light waste, or the sturdy JANUS shape for heavy input material. 

The tearing table is located below the two shafts, which can be used along with the number of tools to determine the particle size. The electrical drive is also available in different power outputs - up to 400 KW can be installed on request. A hydraulic pusher device is optionally available. It ensures continuous material infeed when processing low-density, light or bulky fractions.

The centre distance of the two shafts on the RAPAX has been deliberately selected to ensure that the tools do not interlock. This ensures an optimal infeed torque with minimal energy consumption at the same time.

Rubber buffers have been installed on the drive unit which absorb the impact and protect the gearbox from damage.

Less downtime and easy maintenance

Rubber buffers have been installed on the drive unit, which absorbs the impact and protects the gearbox from damage. The design of the tool and the reversing control system prevent material from wrapping around the shafts or adhering to them, which in turn avoids machine downtime. The machine is also designed to ensure that wear parts such as the shafts and tearing table can be easily removed and replaced. 

Intelligent control system 

The shafts can be controlled with total flexibility, meaning they can move synchronously, asynchronously and in reverse. The RAPAX is designed to shred material in every running direction. The control system makes it possible to select the appropriate program consisting of different movement sequences for every input material.

Plans for the future include using artificial intelligence to make it able to react even more flexibly to the input material. BHS is still collecting the appropriate data for this, but every RAPAX is already equipped to utilize it in principle.
