Small Double Shaft Shredder is a compact yet powerful size-reduction machine designed for workshops, small recycling plants, and pilot processing lines. With its low-speed, high-torque twin-shaft design, it efficiently tears and shears materials such as plastics, rubber, wood, light metal scrap, textiles, and cardboard into manageable pieces for further recycling.
Despite its small footprint, this shredder delivers stable performance, strong cutting force, and low noise operation. The intermeshing alloy steel blades ensure excellent wear resistance and long service life, while the intelligent control system provides overload protection and smooth running.
√ Plastic: PVC, PE, PP, ABS, PET, HDPE, pipes, bottles, barrels, and other soft plastic waste, etc.
√ Wood: tree bark, leaves, wood board, timber planks, lumber, wooden strips, etc.
√ Biomass: sugarcane bagasse, corn cob, palm fiber, coconut shells, etc.
√ Household waste: garbage, fabric, sponge, leather and so on.

Small Double Shaft Shredder operates on a low-speed, high-torque principle to efficiently tear and shear materials into smaller pieces. When waste materials are fed into the hopper, two parallel shafts equipped with intermeshing alloy steel blades rotate toward each other. As the blades grip the material, they apply strong cutting, tearing, and squeezing forces that break bulky or tough items down step by step.
The synchronized rotation of the twin shafts ensures continuous feeding without material blockage, while the low rotational speed minimizes noise, dust, and wear. An intelligent control system monitors the load and automatically reverses the shafts if overload occurs, protecting the machine from damage.

The blade materials of a Double Shaft Shredder play a crucial role in determining its cutting efficiency, wear resistance, and service life. Typically, the shredder blades are made from high-strength alloy steel or tool steel, such as 9CrSi, M6V, Cr12MoV, H13, SKD-11, D2, or Cr12Mo1V1, etc. which offer excellent hardness and impact resistance.
Through advanced heat treatment processes like quenching and tempering, the blades achieve a perfect balance between toughness and durability, allowing them to withstand continuous heavy-duty shredding of metal scrap, plastics, tires, and other tough materials. In some high-end applications, surface hardening or coating technologies are also applied to further enhance wear resistance and extend blade lifespan.
With superior blade materials and precise manufacturing, the Double Shaft Shredder ensures stable cutting performance, reduced downtime, and long-term reliable operation in demanding recycling environments.

These global references not only highlight the proven performance of our Double Shaft Shredder but also reflect our commitment to providing customized recycling solutions and professional support for customers worldwide.
Project 1: In 2023, a JLSS2000D metal shredder was installed in St. Petersburg, Russia to process 15 tons/hour scrap metal and car bodies. The system became the primary equipment in the customer’s recycling line, significantly improving shredding efficiency and metal recovery rate.
Project 2: In 2021, a scrap metal recycling company in Poland installed a Model JLSS2000D metal shredder at its facility to process heavy metals, waste oil drums, and industrial waste. This equipment is capable of continuous operation under heavy loads, processing over 20 tons of scrap metal per hour.
Project 3: In 2019, a recycling company in Romania selected the JLSS2000D model to shred non-metallic materials, steel drums, and aluminum containers.
Project 4: In 2025, a JLSS2000D metal shredder was installed in Algeria to process scrap car frames and heavy steel sections at 18 tons per hour.
Project 5: In South Africa, a client utilizes the JLSS2000D metal shredder as the primary processing unit within a complete scrap metal recycling production line. This shredder is capable of performing impeccable pre-treatment of the material, thereby fully preparing it for subsequent crushing and sorting operations.

Our double shaft shredder can process a wide range of bulky and hard materials, including scrap metal, steel drums, tires, plastic containers, appliances, wood waste, electronic waste, and industrial solid waste. Different blade configurations can be customized according to the material type.
The output size depends on the blade thickness and shaft configuration. Materials are typically shredded into strips or irregular pieces suitable for further conveying, separation, or secondary crushing.
Depending on the model and material type, the machine can process approximately 1–30 tons of material per hour. Capacity may vary based on feeding conditions and material hardness.
A double shaft shredder is designed for tearing bulky and hard materials with strong torque, while a single shaft shredder is more suitable for controlled-size shredding of softer materials such as plastic and wood.
The blades are made from high-strength alloy steel with excellent wear resistance. Blade life depends on the material being processed, but the machine is designed for convenient blade replacement and maintenance.
