Heavy-Duty Industrial Granulators are engineered to break down thick, oversized, and high-volume plastic scrap into reusable granules. They are essential in industries like:
- Injection molding & blow molding
- Automotive parts manufacturing
- Packaging & film production
- Recycling plants for post-consumer waste
- Extrusion and profile manufacturing
These robust machines process…
- Hard and tough plastics
- Thick wall purgings
- Large components like bins, crates, and bumpers
- Production rejects from manufacturing lines
Virtus Equipment specializes in plastic recycling industrial granulators built for long-term durability, performance excellence, and high-throughput operations.
Why Choosing the Right Granulator Matters
Selecting the correct granulator is one of the most important decisions in a plastic recycling or production facility – because it directly affects the quality of regrind, overall equipment efficiency, and operational profitability. A granulator that does not match your material or production requirements can lead to frequent breakdowns, excessive fines and dust, inconsistent particle sizing, and costly downtime. This not only reduces material recovery value but also disrupts downstream equipment such as extruders, washers, dryers, and pelletizers.
An efficiently matched granulator ensures:
- Consistent and clean granule size → essential for trouble-free reprocessing
- Optimized energy usage → preventing wasted power or oversized machinery
- Higher throughput and productivity → more material processed per shift
- Longer equipment lifespan → reduced wear on blades, screens, and bearings
- Lower maintenance and labor requirements → quicker cleaning and fewer stoppages
- Improved safety and operational reliability
Additionally, choosing the right machine helps manufacturers reduce scrap disposal costs and transform more waste plastic into valuable raw material – supporting sustainability goals and circular manufacturing initiatives.
In short, the right heavy-duty granulator becomes a key contributor to your production efficiency and financial return, while the wrong one can become a bottleneck that drains resources, time, and money.
Key Selection Criteria for the Best Granulator
The most important factors when selecting a heavy-duty granulator are:
A. Material Type:
Every plastic behaves differently during cutting.
| Material Category | Examples | Required Machine Characteristics |
| Rigid Plastics | ABS, PP, HDPE molded parts | Strong rotor design, large cutting chamber |
| Thick Production Scrap | Purgings, appliance parts | High torque capability |
| Soft/Flexible Plastics | Film, sheet, thermoforming trim | Tangential feed, anti-wrap features |
| Fibrous / Reinforced Plastics | Nylon-GF, PC-GF | Abrasion-resistant cutting tools |
| Hollow Products | Bottles, tanks | Dual-feed or controlled feeding systems |
B. Throughput Capacity:
Throughput is the output volume processed per hour (kg/hr or lb/hr).
Factors influencing throughput:
- Feed rate — continuous or batch
- Blade sharpness & rotor speed
- Motor horsepower
- Feeding automation (conveyor, robotic handling)
- Screen size design
Choose a granulator that comfortably meets or exceeds:
- Peak production load
- Future capacity expansion
- Scrap volume fluctuations
Under-sized machines → frequent jams & overheating
Over-sized machines → unnecessary energy cost and noise
We help calculate the correct machine sizing for your goals.
C. Output Size Requirement:
Granule size impacts reuse efficiency.
Screen sizes determine:
- Flow consistency for re-extrusion
- Product density
- Quality of final recycled pellets
Common sizes: 6 mm, 8 mm, 10 mm, 12 mm+
(Lower mm → finer granules)
Applications requiring tight material flow tolerance, such as extrusion lines, benefit from smaller mesh screens.
Additional Considerations When Choosing a Granulator:
Beyond material type, throughput, and output size, several practical factors influence how well a granulator performs in your specific environment. Elements such as noise level, maintenance accessibility, cutting chamber design, machine durability, and available floor space all play a role in long-term efficiency. Features like wear-resistant components, safety interlocks, dust extraction systems, and automation compatibility can significantly reduce downtime and operational cost. Evaluating these considerations ensures the granulator not only meets technical processing requirements but also enhances workplace safety, user convenience, and overall production reliability.
- Noise control — Slow-speed rotor or soundproof enclosures
- Durability — Replaceable wear plates & hardened steel components
- Maintenance access — Quick-open housings for blade, screen, rotor cleaning
- Space availability — Proper machine footprint for safe access
- Safety features — Emergency stops, chamber interlocks, overload protection
- Automation compatibility — Conveyors, blowers & full recycling cell setup
- Dust management — Extraction systems for cleaner work environment
These features influence operational uptime and long-term cost efficiency.
