Union Process, which makes particle size reduction and dispersing equipment, has developed a dry grinding SDL250 machine (Attritor) that can be used for recycling fiber material.

‘This is a fairly new application for our Attritors,’ said sales manager Chuck Major. ‘The customer needed a specially designed heavy-duty mill for continuous dry milling of fiberglass and our SDL250 met their requirements. We included a specially designed material deflector to aid in material feeding.’

‘Our customer is thrilled to be able to recycle material that they had previously been discarding as scrap,’ he added.

The stainless steel mill features an elongated design and a flanged inlet for screwfeeding the material. It has a 250 HP TEFC motor suitable for a variable frequency drive (VFD). The mill includes a G-series reducer comprised of a heavy-duty right angle gear box with cooling fan and hardened tool steel agitator arms. Product discharge is achieved via two metering valves for material discharge flow control.
