Achieving Tight Particle Size Distributions In Resin Polymer Grinding
A premier manufacturer of composites and polymers was interested in fine grinding a cross-linked liquid unsaturated polyester resin which had been formed into sheets. The sheets are pre-broken into pieces prior to their final milling. Once the resins are size reduced, they are sent to subsequent manufacturers for further processing into a wide range of products, from boat finishes to print inks.
Starting from an infeed of d90 = 1367 micron, the Fine Grind F10 easily processed the resin polymer to a very narrow PSD bell curve with a d50 of 53.594 micron and a volume weighted average of D[4,3] = 53.618 micron. Varying parameters such as product feed rate, mill RPM, and other operating parameters can effectively shift the PSD bell curve to a finer or coarser profile.
The Quadro Fine Grind F10 is a complete stand-alone process plant that affords benefits to the processor including savings through reduced downtime, minimal space requirements, rapid product changeover and enhanced process efficiency. Other advantages include quick disassembly for maintenance, tool change and cleaning, low power consumption as compared to traditional mills, and low noise. The Model F10 promotes uniform grinding capabilities producing higher yields on specification and has a wide tooling selection to meet all grinding requirements.
