Tria presents new series of granulators at Fakuma
At Fakuma 2024, Tria unveiled its new JN 15 series of granulators – JN 2115 and JN 4215 – dedicated to the injection moulding sector. These new models stand out for the size of the chamber and the conveyor feed opening, as well as the conveyor's geometry, which has been enlarged to ensure the recovery of even large sprues.
In the upper part of the granulator, both hopper and conveyor have been redesigned with a wider opening to almost eliminate the "fly-back" of ground material. The hopper geometry remains customizable to suit different application requirements.
The grinding chamber has also been completely redesigned. With an enlarged opening, the grinding of larger sprues than before is ensured. Both new models come with standard wear-resistant treatment, offering better preservation of the granulator over time, as well as greater flexibility in grinding different materials.
The grinding chamber also features a double counter-blade and a horizontal grid, facilitating and enhancing the discharge of ground material into the funnel.

The rotor geometry is still made from solid material as in the previous version, but now with more openings and a star-shaped design. This improves the grip on incoming material from the hopper, and reduces the formation of strands and dust in the ground material.
When strands form, they remain in the chamber until they reach a size suitable for discharge through the grid holes. This results in reduced noise as well as more homogeneous ground material, free from imperfections and dust.
Test conducted with JN 4215 model also proves energy consumption reduction. As the model is equipped with a 1.5 kW motor, when grinding PP sprues weighing 1.2 g each, approximately 16.5% of the installed power is used when idle, consuming 250 W/h, while during grinding, 20.8% of the installed power is used, producing 30 kg/h and consuming 312 W/h.
The grid holder and funnel are two separate parts, increasing versatility and allowing customization of the discharge area. The funnel is easy to remove and can be unlocked using two expansion closures, while a safety micro-switch and handwheel secure the grid holder, which can only be opened when the granulator is stopped.
This ensures greater safety for the operator, who can tilt the hopper only after removing the funnel, opening the grid holder, and releasing the hopper lock.
With “in-line” motor configuration relative to the grinding chamber, the lateral footprint of the granulator is also kept to a minimum in this series. The motor, along with the rest of the granulator, sits on a base with four wheels, further enhancing stability during movement and positioning next to the machine.
The innovative chamber support brackets also provide a wider maneuvering space for all routine maintenance phases, allowing for greater customization of funnels or special configurations, such as raised bases.
