Low Speed Granulators

  • The GPLUS Range

This solution shares similarities with the GTWIN, offering an excellent grind. However, it operates at a slower speed of 25rpm, which results in quieter operation and less dust in regrind materials.

  • The GTWIN Plus

This model is specifically designed for in-line recycling of sprues or parts. It provides an optimal regrind without compromising the materials’ molecular structure.

  • The MINI Series

As our most compact Low Speed Granulator, this performs reliably while maximising your floor space efficiently and minimising your power consumption (operating at 0.55 kW).

For a deeper understanding of these systems, please delve into the product comparisons provided below.

The GPLUS system shares many similarities with its GTWIN counterpart, primarily in its design for on-site recycling of sprues and parts. It effectively generates substantial quantities of regrind without damaging the material's molecular structure.

What sets the GPLUS system apart is its slower rotation speed (25rpm). This results in a quieter operation with reduced dust in the regrind material, unlike faster granulators. Additional features of the GPLUS systems include:

  • Reverse action rotation to prevent jamming.
  • Low-maintenance design for easy cleaning.
  • Minimal dust creation, with a consistently uniform granule size.
  • Reduced wear of cutting components due to slower rotation speed.
  • A unique modular cutting rotor design.
  • The option of a metal contamination cut-out feature.

For further information about these systems, please consult the datasheet provided below.

The GTWIN MO-DI-TEC range offers unparalleled functionality, engineered for efficient, on-site recycling of sprues and parts. These are specifically designed to generate large volumes of high-quality regrind, doing so without compromising your materials’ molecular structure.

This model guarantees an optimal regrind output, courtesy of its wide cutting chamber and the power of dual gear motors (available in 2x 1.8 kW or an optional 2x 2.2 kW).

Similar to the other MO-DI-TEC granulators, this range also features an innovative tooth design, capable of performing trapezoidal and helical cuts. The GTWIN Plus also boasts a suite of additional features, including:

  • An ergonomic grinder.
  • Reversible combs for versatile use.
  • Dual-function granulometry, with both helical and trapezoidal options.
  • A soundproof steel hopper for noise-reduced operation.
  • Easy cleaning and maintenance.
  • Optional Integrated Metal Detection (IMD) detection.
  • Optional ABS system for additional safety measures.
  • Optional single or double MASHER system for extra efficiency

To learn more, explore the datasheet for the GTWIN PLUS below.

As our most compact Low Speed Granulator, this system operates at 25rpm and is capable of handling very fine sprues, including fibre glass materials, with a diameter between 1-4mm.

The system boasts a unique tooth design suitable for both trapezoidal and helical cutting. Its teeth are safeguarded from damage and wear due to abrasive materials, thanks to its steel-coating resistance. Among its other notable features are:

  • Minimal floor space usage.
  • Lightweight and easily portable at 45kg.
  • Reversible cutters and combs, doubling their lifespan.
  • Low power consumption, at 0.55kW.
  • Significantly reduced dust production.
  • Easy-to-clean design.
  • Extremely quiet operation.

What is a Low Speed Granulator?

A Low Speed Granulator is a specialised piece of machinery used in the plastic recycling process. It is designed to break down waste material into smaller-sized granules – promoting more cost-effective reprocessing and reducing waste.

Unlike traditional granulators, these devices operate at a slower speed, offering more precise and controlled cutting. Low Speed Granulators are sought after for their unique ability to generate high-quality regrind in large volumes without altering the material's molecular structure. This allows the regrind to be directly reintroduced into the production process, thereby saving time and resources.

The granulation of materials, like plastics, can be highly beneficial. It not only aids in recycling efforts by reducing waste but also optimises the production process by reusing materials that would otherwise be discarded. Therefore, anyone seeking to improve their efficiency, reduce waste, and save on material costs may find a Low Speed Granulator an indispensable tool.

The Applications of Low Speed Granulators

Low Speed Granulators are used across a versatile range of applications, notably in the plastic production and recycling industry. More commonly, their function is often seen in injection and blow moulding processes, where they are utilised alongside (beside the press) machines to granulate parts and sprues.

Once the granulation process is complete, the resulting granules are seamlessly reintegrated into the production process, enhancing efficiency and minimising waste. This capability extends to rejected materials, which these machines can repurpose during the inline recycling process. 

This provides an eco-friendly and cost-effective solution for manufacturers, reducing material waste and reprocessing time. The high-quality regrind produced does not compromise the material’s molecular structure, making it suitable for reuse in the production process.

Choosing Your Granulator

At Summit Plastics Automation, we offer a diverse range of granulator units, each designed to cater to a variety of applications. The right system for you will depend on your unique requirements – for help choosing, we recommend contacting our expert team. Alternatively, you should begin by considering the following factors:

  • Intended Application: Ensure your granulator fits your specific processes, whether that’s blow moulding, injection moulding, or something else.
  • Material Selection: Choose a system designed to handle your specific type of plastics for optimal results.
  • Capacity: Select a granulator that aligns with your production volume. 
  • Maintenance: Our range from MO-DI-TEC delivers easy maintenance, safety switches, and accessible screens.
  • Space Efficiency: Consider the size of the granulator in relation to your available floor space. For smaller areas, the compact design of the MINI Series may be beneficial.

Low Speed Granulators: FAQs

A plastic granulator operates by reducing the size of plastic waste into smaller granules, which can be easily reprocessed and reused. The process involves the use of a uniquely designed knife that cuts through the plastic, aided by the granulator’s rotor speed. The size of the granules is determined by the granulator’s screen size.

Low Speed Granulators, like those included in the MO-DI-TEC Goliath range, operate at a slower pace, ensuring precise and controlled cutting. This promotes high-quality granulation without altering the material's molecular structure, making the granules suitable for direct reintegration into the production process.
