Why Choose the Low-Speed Granulators?

Virtus Equipment’s Low-Speed Granulators deliver quiet, adaptable, and efficient granulation for plastic recycling operations. Their direct-drive staggered rotor, special knife design, and maintenance-friendly layout make them ideal for facilities seeking dependable performance with less disruption, cleaner operation, and customizable configurations tailored to specific materials and throughput requirements.

Serving Industrial Recycling Businesses across the USA

Virtus Equipment supplies Low-Speed Granulators throughout the United States, backed by technical consultation, system configuration support, installation guidance, and aftermarket service tailored to plastics recycling operations. Our nationwide support network ensures responsive maintenance, optimized performance, and long-term reliability for industrial recycling and production facilities across the country.

Low Speed Plastics Granulators Description

Virtus Equipment's LS 18 low-speed plastics granulators feature a staggered 180 mm diameter rotor in widths from 180 to 430 mm; concurrently, the LS 30 series has a 300 mm diameter rotor in widths from 400 to 800 mm. A geared motor directly drives the rotor. As well as, its low speed reduces our grinder’s noise level and creates less dust while grinding. The LS-series’s specially-designed knives can be sharpened easily and don’t require adjustment afterward.

Depending on the application, the LS-series low-speed plastics granulators can be fitted with a wide variety of sound-absorbing feed hoppers and base frames, and a built-in blower system with matching suction bins or bag-filling adapters, allowing integration with most types of injection molding machines and robots.

Beside-The-Press Granulators Applications

Virtus Equipment's low-speed plastics granulators are mainly used beside the press machines to grind plastic runners and sprues in injection and blow molding processes.  The resulting granules are then immediately reintroduced into the production process.   In addition, our beside-the-press granulators can be used for rejected products in the in-line recycling process as well. Our LS 30 series’  rugged design allows it to be used for stronger and thicker materials while offering the same advantages of minimized dust and reduced noise at a low speed as the smaller LS 18 series.  Furthermore, these adaptable grinders can also be used as low-noise central granulators for small throughput requirements as well. We are here to help with all your plastic size reduction needs.  LOG Injection Molding Machine will cover your entire spectrum of plastic injection molding machinery.

Benefits for Industrial Recycling Operations

Typical Applications

Virtus Low-Speed Granulators are commonly used in:

These granulators fit well where noise reduction, low dust, and reliable regrind quality are priorities.

Specially-profiled Rotor Knife

The curvature of the specially profiled rotor knives ensures a constant cutting radius after re-sharpening thus maintaining the original cutting gap. Awkward knife adjustment is no longer necessary.

Staggered Rotor Blades

The staggered rotor blades create an individual blade cut thus increasing the cutting torque making the A-series granulators suitable for grinding more solid materials and thicker-walled sprues.

Frequently Asked Questions

What is a low-speed plastic granulator used for?

A low-speed plastic granulator is designed for recycling plastic sprues, runners, and rejected parts directly beside injection molding machines. It operates quietly and efficiently, providing consistent regrind quality without generating excess dust or noise.

Unlike standard high-speed granulators, low-speed models operate at reduced RPMs, minimizing dust, heat buildup, and wear. This makes them ideal for precision molding environments where clean, quiet operation is essential.

Yes. Virtus Equipment’s low-speed granulators are suitable for a wide range of thermoplastics, including ABS, PP, PE, PC, and nylon, making them versatile for various molding and recycling applications.

Virtus Equipment’s low-speed granulators are compact, soundproof, and energy-efficient. They deliver consistent granule sizes, easy maintenance, and reliable performance—perfect for inline recycling at injection molding workstations.
