Types of Twin Shaft Shredders and Applicable Materials

Double shaft shredder is divided into shredding knife shaft designs, which can be divided into single-axis double knife, single-axis four knives, double-axis four knives, double-axis eight knives, and other types. Different knife shaft designs are suitable for different natures and sizes of the material; the choice should consider the amount of shredding, size, material properties, and other factors.

Single-axis double knives:

  • Suitable for softer, smaller pallets, such as waste paper and plastic film.

Single-axis four knives:

  • Suitable for shredding upper media and materials such as cardboard and waste tires.

Double shaft four knives:

  • Suitable for shredding harder and increasing the stock volume, such as metal and waste wood.

Twin-shaft eight knives:

  • Suitable for shredding extremely hard, large storage volumes, such as car wreckage or electronic warehouse.

In addition, the blade material of the twin-shaft shredder should also be selected according to the characteristics of the shredded material. Common blade materials include alloy steel, high manganese steel, cemented carbide, etc. Different materials have different wear resistance and impact resistance.

For example, carbide blades with higher wear resistance are recommended for metal or electronic components shredding, for applications that require shredding paper or plastic film, alloy steel blades with better impact resistance can be used.

Companies and individuals can dramatically improve shredding efficiency and meet different emission processing needs by appropriately selecting dual-shaft shredder varieties and blade materials.

 

Selection of Key Components for Twin Shaft Shredders

Processing capacity and material type:

  • Determine the type, quantity, and size of waste to be processed. Different materials (such as metal, plastic, or paper) require different shredding weapons and power.

Shred size:

  • Select a shredder that matches the required shredding size. Smaller sizes are suitable for recycling, while larger sizes are suitable for waste disposal.

Shredding rate:

  • Consider the shredding rate required to ensure the machine can handle the waste. Shredding rates are measured in kilograms per hour (kg/h).

Power system:

  • Choose an electric, hydraulic, or diesel power system, depending on application requirements and budget.

Safety:

  • Prioritize machines with safety features such as emergency stop buttons, overload protection, and noise blocking.

Maintenance:

  • Choose machines that are easy to maintain and replace spare parts to reduce operating costs. Consider spare parts availability and repair services.

Durability:

  • Choose machines made from high-quality materials to ensure durability and longevity. Check the durability of shredding knives and machine tools.

Funding:

  • Take grants into account and select machines that meet needs and financial constraints.

Advantages of double shaft shredder

Reduced supply volume

  • Twin-shaft shredders can effectively reduce inventory volume, thereby reducing storage and transportation costs, which is helpful for bulky wastage.

High processing capacity

  • The twin-shaft design of twin-shaft shredders allows them to process large quantities of debris at a high processing capacity, thereby increasing productivity.

Suitable for a wide range of stockpiles

  • Twin-shaft shredders have a high shredding capacity and can be used for various rips, including plastics, paper, wood, metal, and electronic equipment.

However, there are some disadvantages of twin shaft shredders:

High investment cost

  • Compared to other types of shredders, dual-shaft shredders have a higher investment cost, which may be a consideration for small businesses or companies with limited budgets.

Maintenance costs

  • Maintenance of twin shaft shredders is relatively high, and due to their complex structure and components, regular maintenance and replacement of knives are required.

Noise and vibration

  • Twin shaft shredders can generate high noise and vibration levels during operation, which may require additional measures or isolation equipment.

When choosing a twin shaft shredder, it is essential to carefully evaluate its advantages and disadvantages and modify whether it suits the needs and budget of a particular application.

Care and Maintenance Recommendations for Twin Shaft Shredders

Regular Cleaning and Maintenance

  • Regularly clean the inside of the shredder to remove debris, damage, etc., to prevent clogging and compromising operational efficiency.
  • Remove shreds and dust from the shredder housing to avoid dust-causing overheating.

Knife Maintenance

  • Check knives for sharpness; dull knives can reduce shredding efficiency and increase blades.
  • Replace knives regularly based on frequency of use to ensure optimal shredding results.

Bankruptcy Lubrication

  • Check waste bits regularly and add or replace them according to the manufacturer’s recommendations.
  • Required lubrication reduces friction and extends the life of the machine.

Rust maintenance

  • Care should be taken to prevent rust when using the shredder in a humid environment.
  • Periodically apply rust inhibitor to the spindle and housing to prevent rust and corrosion.

Other Maintenance Recommendations

  • Avoid shredding metal, plastic, and other complex objects to prevent knife damage.
  • Do not overload the shredder; overload will cause a burden on the machine’s life.
  • In case of abnormal failure or noise, stop using it immediately and contact maintenance personnel.

 

Conclude

When choosing a twin-shaft shredder, it is critical to carefully evaluate your needs and understand the different types and features available. With these vital factors, you can find the perfect machine for your specific application and budget. In addition, following proper care and maintenance procedures can extend the life of your twin shaft shredder and ensure its efficient operation.
