Description & Application

Double shaft shredder is appropriate for waste materials recycling requirements of various industries, such as electronic waste, plastic, metal, wood, scrap rubber, packing barrel, layer board and so on. There are a wide range of recyclable materials, and materials after shredding can directly be reused or for further refining treatment according to requirements.

This double shaft shredding machine has the characteristic of slow speed of revolution, high pulling torque and low noise, etc. Adopting PLC(Programmable Logic Controller) control system, it can automatically control the start and stop function, reversal function, and automated inversion of control function when overloading of this twin shaft shredder, which greatly lowers labor and meanwhile generates high efficiency.

  • Rubber Recycling: rubber sheet, rubber pad, car tires, heavy truck tire
  • Metal recycling: steel drum, steel sheet, steel cans, aluminum cans, aluminum rods, etc.
  • E-waste (electronics waste) or WEEE recycling
  • Wood Recycling: lumber, wooden pallets, furniture, tree branches, wooden frame, etc.
  • Destruction of products for liability issues suchas sensitive documents including computer storage media such as hard disks, x-rays, expired goods, outdated stock, pharmaceuticals, etc.
  • Size reduction in wastewater treatment plants and other municipal applications.
  • Pre-cutting other solids such as destruction of foods, pallets, steel and plastic drums, furniture, construction debris, containers, corrugated boxes, packaging, labels, and other bulky materials.

Product Details

double shaft shredder chassis

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

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.

Segmented Blades

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.

motor

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.

Planetary reducer

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.

double shaft shredder electronic control

Electronic Control

The whole model adopts frequency conversion control and conforms to international standards such as CE/CSA.

Hydraulic Force Feeder

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.

Rotary Screen

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.

Working Principle

For different materials, there should be different blade types. Our twin shaft shredder has four different blade type: one-claw blade, two-claw blade, four-claw blade and multiple claw blade, and the thickness ranges from 10mm to 80mm. The blade type and blade thickness can be designed according to the materials and requirements of customers. The installing form of blade can be divided into integral installation and detachable installation (we recommend to use detachable installation for Model XD-1000 and the above model machine, convenient for later blade replacement).

Advantages

  • Main engine of double shaft shredding machine adopts high grade steel plate for welding, making sure the stability of equipment in long time heavy loading.
  • Shaft block adopts the patented detachable type, which makes it convenient to tear down the moving blade, fixed knife and other component quickly, and easy to maintain and replace the blade.
  • Moving blade adopts special alloy tool steel as material and uses precision forging machine to forge, and it is able to be re-used and repaired to use through multiple heat treatment and low temperature refrigeration treatment. While the stationary knife adopts the patented hook type installation, optimizing cutter changing function.
  • Cutter shaft is crafted from high-intensity and heavy-load dedicated steel, cooperating with cutter more reasonably to provide strong power for cutting.
  • Compared with single shaft shredder, the double shaft shredding machine can easily crush large size materials, like board, wood, tire and so forth.
