New ThermoPRO granulators from Rapid Granulator

At NPE2018, size reduction equipment manufacturer Rapid Granulator is introducing a new range of granulators designed specifically for in-line processing of skeletal waste from sheet and film thermoforming lines.

The new patent-pending ThermoPRO Series – based on an already patented Rapid design – is available in various standard and low-built formats for handling scrap widths from 600 to 1,500 mm (24-60 in.). A ThermoPRO 400-90 for granulating webs up to 900 mm in width (35 in.) will be on display at the company’s booth, W953, in Hall A during NPE2018.

ThermoPRO machines combine features already proven on other Rapid granulators – double-scissor cutting action, an “open hearted” design for fast production changeovers and ease of maintenance, a mineral composite base for high stability and low noise, for example – with numerous new elements that were tailor-made to make thermoforming operations easier to run and more cost-effective.

Several special features should make ThermoPRO granulators especially attractive to thermoformers. Immediately obvious are the highly compact designs of the integrated roll feed and dancer bar. Together, these enable the skeleton to be pulled into the machine, which is running constantly, in sync with the production line, which operates discontinuously. The roller feed has a pneumatic pressure control that enables it to adapt to the thickness of the incoming material.

The ThermoPRO uses a heavy-duty roller feed as standard, enabling problem-free handling of the skeletal waste. This even makes it possible to run several webs into the granulator at the same time. It also facilitates granulation at the start-up of a thermoforming line, when the parts are not stamped out of the sheet, meaning that the entire web, trim and parts together, needs to be fed into the granulator.
