Technical systems
[1] Infeed hopper
The loose feed material is loaded into the infeed hopper, which is individually adapted to the material and type of feeding.
[2] Rotor
The rotor is produced from a solid forged part. A rotating wear protection element protects the rotor edges at the housing mounting point from wear.
[3] Blades
The blades of the rotor and static blade seat are versatile and can be rotated or replaced in just a few steps. The style, quality and number of blades is configured to match the specific application at hand.
[4] Screen unit
The screen consists of multiple segments that can be replaced individually. The screen support can be rotated downwards. This makes it significantly easier to perform maintenance work.
[5] Drive
The drive is frequency controlled, and the speed of the rotor is freely adjustable between 80 and 240 rpm. As a result, the machine can be configured to account for the properties of different feed materials.
Static blade seat with blade segments
Static blade seat with blade segments
The modular static blade seat is equipped with multiple blade segments. This modular design enables easy adjustment of the blades and ensures consistent cutting quality.
Movable base plate
Movable base plate
A hydraulically movable base plate simplifies the removal of contaminants and facilitates access when performing maintenance work.
Isolated rotor bearing
Isolated rotor bearing
The rotor shaft bearings are located in a double-walled housing. This protects the shaft bearings from the effects of heat and dust, which increases their service life.
Hydraulic pusher unit
Hydraulic pusher unit
A hydraulically driven slide pushes the material along the base plate and toward the cutting system where cutting takes place.
The loose feed material is loaded into the infeed hopper. A hydraulically driven slide pushes the material along the base plate and toward the shredding system. The feed material is shredded between the rotor equipped with blades and the counter-blade mounted on the static blade seat. Once the shredded material reaches a defined particle size, it falls out of the machine through a screen basket. The size of the discharge material is defined by the hole pitch of the screen. It can range from 10 to 120 mm.
Inert design
Variant for hazardous waste
When crushing potentially hazardous recyclable, residual and waste materials (lithium-ion batteries, toxic waste materials, and the like), inertization of the working chamber is required to prevent fires, explosions, hazardous gas leaks or chemical reactions. For process reliability in processing these problematic materials under a protective atmosphere and to protect the health of employees, BHS offers the universal shredder (NGU) in an inertizable design with an external motor.
