Lower discharge temperatures and improved flow rates are obtained for the processing of meltable, solid crosslinkable compositions comprising a polymer, e.g., polyethylene, and a peroxide, in a single barrel extruder by equipping the extruder with an energy transfer (ET) screw that comprises: (1) an ET section with a distance averaged ET section depth of 8.0% to 10% of the extruder barrel internal diameter, and (2) a metering section with a metering section depth of 6.0% to 8% of the extruder barrel internal diameter.

A screw for a plasticating apparatus has one or more helical flights. A portion of the screw has a plurality of advancing grooves arranged in a noncontinuous helix cut in the screw. The advancing grooves are dimensioned to receive material therein as the material is conveyed through the barrel. The screw has a plurality of noncontinuous cross-cut grooves traversing one or more of the advancing grooves. The cross-cut grooves have a second helix angle greater than the first helix angle and less than ninety degrees; and/or one or more of the cross-cut grooves have a third helix angle of about ninety degrees.

Methods for granulating powder in a single piece of equipment include at least the following: (a) continuously introducing the powder and a granulating fluid to the single piece of equipment; (b) passing the powder and the granulating fluid through a granulating zone of the single piece of equipment to form wet granules; (c) passing the wet granules through a drying zone of the single piece of equipment; (d) optionally passing granules through a discharge zone of the single piece of equipment; and (e) continuously discharging the granules from the single piece of equipment where the single piece of equipment is not a fluid bed processor.
