ZY-KC industrial plastic crusher: the equipment series for shredding and granulating plastic, rubber and wood waste in recycling and production plants. With 5 available models (ZY-KC 500, 600, 800, 1000 and 1200) this family of industrial plastic crushers covers capacities from 300 kg/h up to 1,200 kg/h, for recycling operators, granule producers and industrial waste managers of small, medium and large scale.
The rotary and fixed blades made of high-performance alloy steels (9CrSi, Cr12MoV, SKD-II or D2, selectable according to the processed material) ensure precise and uniform cutting. The grinding chamber with noise dampers, the heat-treated frame and the quick-change screen complete the profile of an industrial plastic crusher built for continuous use in demanding production environments.
Key advantages of the ZY-KC industrial plastic crusher
• High-performance alloy steel blades: material selectable from four options (9CrSi, Cr12MoV, SKD-II, D2) according to the type of plastic and the hardness of the material. Significantly longer service life compared with standard carbon steel blades, lower replacement costs over the long term.
• Grinding chamber with noise dampers: reduced noise level compared with crushers without sound insulation. Easier compliance with occupational health and safety regulations regarding noise exposure in industrial halls.
• High-quality, heat-treated steel frame: superior resistance to torsion and deformation under repeated impact loads. Structural rigidity that maintains blade alignment throughout the entire service life of the equipment.
• Quick-change screen: the screen support frame locks and unlocks quickly, without special tools. Changing the screen to modify the granulation of the final product takes minutes, not hours.
“Fixed and rotating knives in optimal combination: the system with 2–4 fixed knives and 15–42 rotating knives (depending on the model) ensures a cut.”
• Wide range of capacities: 5 models from 11 kW / 300 kg/h up to 77 kW / 1,200 kg/h. Precise model selection for the actual processing capacity, without costly oversizing or undersizing with the risk of overload.
• Material versatility: processes rigid and flexible plastic (PET, HDPE, PP, PVC, ABS), rubber, wood and mixed industrial waste with a dominant plastic component.
• Fixed and rotary blades in an optimal combination: the system with 2–4 fixed blades and 15–42 rotary blades (depending on the model) ensures efficient shearing, with controlled energy consumption per tonne processed.
• 60-month warranty: extended coverage for an industrial plastic crusher in continuous production, with spare parts in stock at UZINEX.

Choosing the blade steel: what matters for the industrial plastic crusher
The choice of material for the blades of a ZY-KC industrial plastic crusher has a direct impact on the total cost of operation over the long term. The four available options cover different profiles of wear resistance and toughness.
• 9CrSi: alloy tool steel with good wear resistance and moderate toughness. Suitable for soft plastic (PE, PP, PET) and mixed waste without abrasive or hard components. Lower cost than the higher-grade variants.
• Cr12MoV: tool steel with high hardness (58–62 HRC), excellent resistance to abrasive wear. Recommended for rigid PVC, ABS and plastics containing glass or abrasive particles.
• SKD-II (Japanese D2 equivalent): performance similar to D2, with slightly higher toughness. A good compromise for lines that process varied materials.
The ZY-KC range is an industrial plastic shredder chosen by operators who process significant volumes of waste.
Recycled plastic granule producers use a ZY-KC industrial plastic shredder as the first stage in the line of.
Wooden furniture and particleboard manufacturers use the ZY-KC models to shred wood offcuts.
• D2: cold-work tool steel with the highest wear resistance in the range (60–62 HRC). Maximum service life under intensive processing of hard plastics or materials with a high abrasive content.

Industrial applications for the ZY-KC industrial plastic crusher
The ZY-KC range is an industrial plastic crusher chosen by operators who process significant volumes of plastic, rubber or wood waste and need controlled granulation, high availability and predictable maintenance costs.
Producers of recycled plastic granules use a ZY-KC industrial plastic crusher as the first stage in the processing line. Collected plastic waste (PET bottles, HDPE packaging, PP parts, PVC profiles) is cut into flakes and granules of uniform size, controlled by the choice of screen, before washing, drying and extrusion into final granules.
Industrial waste managers and selective collection operators choose an industrial plastic crusher to reduce the volume of bulky plastic waste (crates, containers, canisters, profiles and technical parts) making transport and storage easier before recovery. Volume reduction with the ZY-KC crusher can reach 70–80% compared with the unreduced material.
Manufacturers of wood and chipboard furniture use the ZY-KC models for shredding wood, chipboard and MDF scrap resulting from cutting and processing. The shredded material is reused as fuel in biomass power plants or as raw material for particle boards, eliminating the cost of waste disposal.
How the ZY-KC industrial plastic crusher works
The operating principle of this industrial plastic crusher is based on shearing the material between the rotary blades mounted on the rotor and the fixed blades mounted on the frame of the grinding chamber. Material fed through the upper inlet is caught between the blades and cut progressively until the fragments are small enough to pass through the openings of the lower screen.
The granulation size of the final product is controlled directly by the size of the screen openings: by changing the screen, you change the granulation without modifying anything else on the equipment. The ZY-KC quick-change screen allows adaptation to different granulation requirements within a few minutes, essential for operators who process different materials on the same industrial plastic crusher during the same working day.
Frequently asked questions about the ZY-KC industrial plastic crusher
What types of plastic does the ZY-KC process?
This industrial plastic crusher efficiently processes: PET (bottles, films), HDPE (canisters, crates, pipes), PP (packaging, automotive parts), rigid PVC (profiles, pipes, sheets), ABS (technical parts, housings), PE (films, bags), PS and pre-compacted EPS. For materials with high hardness or abrasive content, D2 or Cr12MoV blades are recommended.
How do I determine the right model for my processing capacity?
The actual capacity of an industrial plastic crusher depends on the type of material, the dimensions of the input pieces and the desired output granulation. As a general rule, for mixed materials and medium granulation (10–20 mm), you choose the model whose nominal capacity equals your average daily volume divided by the planned operating hours. UZINEX engineers calculate the optimal model based on your concrete specifications, free consultancy available .
How often must the blades be sharpened or replaced?
The sharpening interval depends on the material and the daily volume. When processing PET and HDPE, D2 blades can be sharpened at 300–500 hours, with 4–6 sharpening cycles before replacement. UZINEX keeps spare blades in stock for all ZY-KC models, details on the technical support page .
Does it require a special foundation?
The small ZY-KC 500 and 600 models can be mounted on a standard industrial floor with chemical anchors. The ZY-KC 1000 and 1200 models benefit from a reinforced concrete foundation to absorb vibrations and maintain blade alignment over the long term. UZINEX provides the installation specifications on delivery.
Is it eligible for EU funding?
Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for EU-funded projects, including for the recycling and circular economy sector. The complete technical documentation for funding applications is provided on request. Leasing options on the credit and leasing page .
