Abstract
The specific energy input required to finish resin particles is considerably reduced when the resin particles are passed through a continuous finisher wherein the volume utilization of the finisher is between about 40 volume percent and about 95 volume percent, the tip velocity is between about 500 and 800 inches per second and the superficial mixing intensity exceeds about 0.7 kilowatts per liter.
Claims8
An improved process for finishing particulate resin by continuously feeding said resin into a finisher and mechanically working said resin in said finisher to provide finished resin having an elevated temperature, thereafter discharging said finished resin from said finisher, the improvement comprising operating said finisher at a volume utilization of between about 40 and about 95 volume percent at a tip velocity of between 500 and about 800 inches per second and a superficial mixing intensity of 0.7 to 1.1 kilowatts per liter.
