Product Overview

Core Selling Points for Shredder

Running at 50RPM low speed with 45KW high-power main motor, the machine delivers strong torque without high friction heat.

Equipped with 39 moving knives + 2 fixed knives made of high-quality DC53 alloy steel. Compared with ordinary blade materials, DC53 features higher hardness, better wear resistance and excellent anti-corrosion performance.

Supported by a 5.5KW hydraulic ram system, it realizes automatic, continuous and stable material pushing. It can handle long plastic pipes, bulky plastic profiles and lump materials directly without pre-cutting.

Matched with 60MM standard screen mesh, the shredded materials have uniform particle size with no oversized bulk materials.

With a stable hourly output of 500-700KG, it fully meets the primary shredding demand of medium-sized plastic recycling factories, featuring high operational stability and low failure rate for long-time continuous production.

Core Selling Points for Crusher

Adopting 480RPM high-speed rotor design and 37KW matched power, it performs precise secondary fine crushing on coarse shredded materials.

The final 12MM uniform granules are fine and even, which can be directly used for granulation, mixing and reprocessing.

Equipped with 24 moving knives + 2 fixed knives, the dense and sharp blade combination forms an efficient circulating shearing system.

The whole set of blades adopts 9CrSi tool steel, which has high hardness, good toughness and excellent cutting performance.

Stable fine crushing capacity reaches 400-500KG/Hr. The power configuration is reasonably matched, which avoids energy waste while ensuring crushing efficiency, realizing energy-saving and high-efficiency production.

Core Advantages

01

Coarse Shredding

The 45 kW, 50 RPM shredder accepts long pipes and bulky waste and uses a hydraulic ram for stable automatic feeding.

02

Durable Shredder Blades

DC53 wear- and corrosion-resistant blades are suited to continuous PVC processing and can be resharpened.

03

Uniform Fine Crushing

The 37 kW, 480 RPM crusher turns pre-shredded pieces into consistent 12 mm granules.

04

Balanced Complete Line

Higher upstream shredding capacity and 400–500 kg/h downstream crushing capacity support continuous operation without material accumulation.

Frequently Asked Questions

What is the difference between the shredder and crusher?

The shredder performs primary coarse reduction at 50 RPM with 60 mm output. The crusher performs secondary fine crushing at 480 RPM with 12 mm output.

Can the machines work independently?

Yes. The shredder can process bulky waste alone; the crusher requires small, pre-shredded fragments.

Can screen sizes be customized?

Yes. The standard shredder screen is 60 mm and the crusher screen is 12 mm; other sizes are available.

What blade materials are used?

The shredder uses DC53 alloy and the crusher uses 9CrSi tool steel. Both can be resharpened.

Will the crusher burn plastic?

No under correct, uniform feeding. The matched 37 kW drive and 480 RPM speed control friction heat.

Does the shredder have anti-jam protection?

Yes. Its 5.5 kW hydraulic system can retreat and reverse during a jam.

What is the complete line capacity?

Matched operating capacity is approximately 400–600 kg/h.

What materials can it process?

Rigid PVC, PE and PP pipes, profiles, injection rejects, purge and hard plastic lumps.
