Two Roll Mill For Grinding Pu Foam

Methods for polyurethane and polyurethane composites ...

01/08/2007· During the early 1990s two-roll milling was found to give the best result for flexible PU foam grinding, whilst for rigid PU foams ball mills may yield particle sizes as small as 85 μm. One factor that limits the amount of scrapped PU foam that can be recycled by regrinding is the viscosity of the polyol/fine particle mixture that can be handled by the processing equipment. In practice this ...

POLYURETHANE MACHINING INFORMATION

Two-fluted end mills and single point fly cutters are preferred. Fly cutters would utilize high speed tool bits ground to a round nose. Speed of the cutter should be 900 to 1300 rpm. A feed rate of 15 to 20 inches per minute is a good starting point.

Machining Polyurethane - Practical Machinist

12/03/2018· the slots don't have to be more than about 1/2" deep into the grind wheel, and space them about every inch or two around the circumference of the wheel. I think the bond of the wheel is plenty strong enough as long as you don't crack the wheel in the process. Pluck it with your finger before mounting on the grinder to make sure it rings and if it just thuds, throw it away.
