Scrap PCB Computer Board Cell Phone Board Recycling Shredder Application:
The PCB recycling shredder operates on a robust dual-shaft shearing principle: two counter-rotating shafts equipped with interlocking hardened steel blades pull the circuit board material into the cutting chamber, where it is progressively sheared, torn, and fractured into irregular fragments. The low-speed, high-torque design ensures powerful processing without generating excessive heat, preventing the vaporization of hazardous substances commonly found in PCBs (such as brominated flame retardants). The shredded output—typically 50–80mm fragments—provides an ideal feedstock for downstream metal liberation and separation processes, significantly improving the recovery efficiency of copper, gold, and other precious metals in subsequent refining stages.

Scrap PCB Computer Board Cell Phone Board Recycling Shredder Description:
The working principle of the waste glass fiber recycling shredder is efficient and direct: the equipment is driven by an electric motor to rotate the internal cutting blade at high speed. When the waste glass fiber product (such as waste fiberglass) enters the feeding port, the blade quickly cuts and tears the material, ultimately crushing it into small pieces or fibrous materials, achieving efficient crushing and resource recovery of waste glass fibers.

Circuit Board Shredder in a WEEE Recycling Line
Circuit board recycling consists of shredding and separation. For the first shredding machine, we choose the double shaft shredder. After circuit board shredding, the particles are around 60mm by 60mm. Next, the second crushing machine is a granulator, resulting in 20mm particles. Then the shredded material is collected in a mesh box and processed further. The shredded PCB will be separated by the air separator and the electrostatic separator.

The whole metal recycling system has the advantages of unique structure, large output(500kg to 2000kg/hr) and power saving. The final material is separated into 99% pure copper, 98% iron and 95% plastics.

Double Shaft Shredder Blades:

Components:

Shredder Chassis The whole chassis is made of welded steel plate and finely machined by CNC gantry milling, which has high bearing capacity, high impact resistance and more stable quality.	Shredder Spindle The shredder spindle is made of high alloy, forged and heat-treated and tempered as a whole, and then machined into hexagonal, octagonal and spline form by CNC gantry milling after fine turning, with long service life.
Shredder Blade The shredder blade is made of special steel, forged, faded, refined, vacuum heat treatment, computerized wire cutting, CNC grinding machine processing.	Segmented Blades The segmented blade design can greatly reduce the blade changing time and cost. The blade comprises of the blade holder, and two types of blade segments, with and without hooks. Worn blade segments can quickly and easily be removed and replaced by simply removing the securing screws.
Hydraulic Force Feeder(optional) A hydraulic force feeder is available to actively press the input material down into the cutting zone between the two shearing shafts. This holding action prevents material from riding over the blade hooks, thus greatly improving the cutting efficiency and throughput of the machine.	Planetary Reducer The reducer chassis adopts welded box, helical gear, planetary gear transmission, with small volume, low noise, high torque and other characteristics, higher transmission efficiency.
Motor The motor adopts Siemens, Wanan and other domestic brands of pure copper motor, with stable and reliable quality, and can be customized according to requirements.	Rotary Screen(optional) To effectively control the output product size, a circular screen mounted around the cutting chamber is the ideal solution.The rotary screen runs at low speed, the oversized fractions are recirculated back to the cutting chamber for further shredding, whilst the sized fraction falls through the screen to the next process.

Scrap PCB Computer Board Cell Phone Board Recycling Shredder Technical Features:
This device can be used as both a primary and secondary shredder, and is widely used in various fields such as waste management and biofuel production. Adopting a dual axis, low-speed, high torque design, equipped with a hardened steel knife, it can easily chop large pieces of hard plastic, tires and other heavy objects, demonstrating strong processing capabilities. Its dual axis structure enables it to handle a variety of different materials, with a powerful built-in engine, long working cycle, large feeding volume, and support for direct feeding by forklifts, improving operational efficiency.
Structurally, the shredder adopts a heavy-duty design, with the frame and components made of thick sheets and tubular materials, and the blades made of high-quality steel to ensure durability and long life. The quantity, quality, and shape of blades can be customized according to specific needs to meet different job requirements.
In terms of intelligence, the device is equipped with a built-in PLC controller, which can effectively sense and handle overload situations, and clear foreign objects by stopping and reversing the shaft rotation to ensure safe operation. In addition, the disassembly and replacement of cutting tools are designed to be both safe and convenient.
It is worth mentioning that the shredder adopts a planetary gearbox instead of a traditional gearbox, which improves efficiency and stability. At the same time, it has a compact size, high torque density, cost-effective precision, and high radial load capacity, further enhancing the overall performance of the equipment.
