Plastic foam crushers offer the potential to produce a variety of products from recycled foam. The flexibility of this shredder allows for the development of new reuse methods. The Shuliy EPS foam crushing machine tears bulk-expanded polystyrene and many other foams into smaller pieces. These foams come out through a screen before being collected. We offer different screen components. The screen inserts you choose determine the size of foam that can leave the foam shredder machine and continue to be collected.
Introduction of Plastic Foam Crusher
A plastic foam crusher or EPS foam crushing machine is a recycling machine that makes EPS EPE foam blocks into shredded pieces for further recycling, such as extrusion pelletizing. The machine also reduces the volume of the foam for easy transportation.
Shuliy also offers a range of EPS foam crushing machines for the recycling of various scrap materials. Our products include single-shaft shredders, two-shaft shredders, and four-shaft shredders. They are ideal machines for shredding plastic bottles, plastic tapes, plastic drums, and various plastic products. We can customize the foam shredder machine according to the customer’s requirements.
Working Principle of Plastic Foam Crusher
The working principle of the plastic foam crusher is to shear, tear, and extrude the foam material through the high-speed rotating blade or roller to crush the large pieces of EPS, EPE, EPP, and other foams into small particles or fragments, to facilitate the subsequent compression, granulation, or recycling process.
- Feeding: The operator puts large pieces of foam into the machine through the inlet.
- Pre-compression: Foam is fed into the crushing chamber by gravity or screw propeller.
- Crushing: Multiple sets of blades mounted on the spindle rotate at high speeds to quickly cut and tear the foam.
- Screen to control the discharge size: The crushed foam particles are discharged through a screen with an adjustable aperture to control the final discharge size.
Core Structure and Detailed Design of Styrofoam Shredder
The core structure of the plastic foam crusher includes a reinforced steel frame, a high-torque motor, a rotor system that drives the knife and stator knife, and a replaceable screen unit. These components work together to efficiently crush bulky foam into uniform particles.
High-speed rotary blades
- The tool material is spring steel, high hardness, good wear resistance, and long life.
- The tool supports disassembly and multiple grinding, easy maintenance, and low cost.
Industrial Control Panels
- The equipment is equipped with a special control box containing digital display instruments, independent control buttons, and an emergency stop system.
- Real-time monitoring of motor status, current and voltage, and running load.
Adjustable screen device
- Use: Control the particle size of foam discharge
- Common aperture: 10 mm- 50 mm (can be customized)
- Material: stainless steel or wear-resistant steel
These parts are the core components of the plastic foam crusher. If you want to know more about the information, please feel free to contact us.

Optional Configuration of Styrofoam Crusher
| Mahcines | Functions |
| Foam compactor machine | Styrofoam compactors compress bulky foam waste (e.g., EPS, EPE) into high-density blocks to reduce volume for storage, transportation, or subsequent recycling. |
| Plastic foam extruder | Plastic granulator is used to process waste plastics into reusable plastic pellets for re-production through melting, filtering, drawing, and other processes. |
| Cooling tank | Cooling tanks are used to rapidly cool the extruded plastic strips during the plastic pelletizing process to ensure that they are hardened and molded for easy pelletizing. |
| Plastic granule cutter | A plastic pellet cutter is used to cut cooled plastic strips into uniform granules for subsequent storage, transportation, and reprocessing. |
Raw material of EPS Foam Crushing Machine
Shuliy EPS foam crushing machine can shred EPS, EPE, polyethylene foam, polyurethane foam, memory foam, and most types of foam into smaller pieces. And there is no need to compact the foam like other shredders. The shredder is designed for foam, so it can run continuously without the problems encountered with other methods.
