Ecnomic Single Shaft Shredder For Cable 

Cables are widely used in our daily life, from electric cable, power cable to communication cable and data cable. Production of cable scrap in the Western world amounts to approximately 1,000 tons per 1 million population. Accumulation of abandoned cable posts potential fire hazard which can bring harmful effects on nature and human beings. A specialist field of cable recycling is therefore in strong demand.

Most cables consist of a metal conductor inner housed in a plastic insulation, and the most common metals used in cables are copper and aluminum. Approximately 60 to 80% of the weight of cables comes from the metal contained inside it. The main driving force to recycle cable waste is to recover the valuable metal portion; copper and aluminum are non-renewable metal whose exploitation incurs serious environmental effects. These metals after recycling don’t degrade, thus they can be recycled indefinitely.

The decisive step in cable recycling processes is the possible entire separation of the metal fraction from the plastic insulation. A typical scrap cable recycling line consists of a combination of different cable single shaft shredders, granulators for material reduction and disintegration, as well as separation lines for separating metal from the plastic part. The reclaimed metals and plastic are then melted and reused to make new products.

ENERPAT’s size-reduction & separation line is specially designed for processing mixed cables of various size and composition, which mainly includes following equipment:

Cable single shaft Shredder – for primary size reduction of scrap cables

Magnet Separator – for separating the liberated steel from the shreds

 Granulator – for secondary size reduction of the shredded cable pieces so that copper or aluminum can get detached from the plastic insulation.

Air Separation – for separating plastic from metal shreds with the principle of different density

Conveyors – for transporting material from one machine to another –

De-dusting system –for removing dust from the output shreds and meanwhile keeping the working environment clean and healthy.

Rotor

• Chevron rotor design

• Rotor knives manufactured from special heat treated DC53 steel. They can be rotated and used on four edges before replacement

• Long life fixed blades that can be adjusted to maintain cutter clearance

• Wear resistant coating. Optional for applications involving abrasive material such as fibre glass

Screen Basket

• Quick change screens for accurate particle size control (sizes 12-100mm)

• Safety limit switch fitted to screen access door to prevent machine operation whilst access door is open

• Cylinders access door opener mounted on V800-V1500 series for easy opening and access

• Star screen is available as an option for thin and/or flexible material such as film

Bearings

• Oversized, high quality spherical shaft bearings are isoloated from the cutting chamber to prevent product migrations through the grease seals

• Bearing housing integral machined to ensure the longevity of the bearings

• Rotor water cooling. Optional water cooling through the bearing housing to the rotor

Ram

• Segmented shredding chamber floor with brass guides

• Machined, one-piece segmented floor

• Advanced adjustable sealing system for the pushing unit

• Fines discharge chute to the collect the fines during shredding and to protect the  hydraulic power pack

Drives

• Electric drive motors configured for Star/Delta starting. Fluid coupling mounted on V1200 and V1500

• Heavy duty reduction gearbox mounted directed onto the rotor shaft

• Shock absorbing gearbox mountng arrangement to reduce stress on drive components

Hydraulic System

• Twin speed hydraulics, faster speed for backwards to maximise the shredding throughput

• Integrated oil/air cooler to maintain temperature for continuous operation

• Optional cover insulator for applications that may eject hazard particles such as wood shredding.

Control Panel

• Standalone electrical control panel with Siemens PLC control system and Schneider electrical components.

• Manual and automatic controls for rotor direction and hydraulic force feeding device

• Intelligent programming whereby the motor automatically reverses on overload and stops when the machine is idle
