PROSINO silent granulators/crushers are one of the most popular equipment in our product range. Attributed to its low speed operation and the dual-layer construction of the body shell, this series machine runs silently with the noise level of only 75dB more or less. Standing next to it, you won’t have the feeling of being bothered by the operation at all. For those facilities who are bothered by the large noise generated by normal granulators, this silent granulator is a great “saviour”.  No matter processing rigid products or soft products, this granulator always works in a quiet way.

Besides the sound-proof feature, this series granulators also have a few other advantages compared to a normal granulator. It has timing function that provides much flexibility for users to choose a suitable time to have the machine automatically started or stopped. If connecting with a blowing system for output material collection, the bottom hopper is attached hermetically to the machine chamber that not only helps reduce noise but also keep environment dust free.

This silent granulator can be applied in many fields of recycling. Plastic products manufacturers can use it for crushing extrusion purgings or injection runners; rubber products manufacturers can use it for granulating scrap rubber generated during production; cardboard plants can use it to crush the board trims and offcuts.

Granulating Application For Silent Granulator:

Plastic: Plastic bottles, injection runners, extrusion purgings, plastic film
