Erema runs recycling demonstrations at HQ
Erema North America installed a new recycling demonstration line at its headquarters in Ipswich, Mass.
The 906 T is designed for reclaiming low density polyethylene, linear low density PE, high density PE and polypropylene in both rolls and loose materials. The system includes a roll-feed and conveyor belt with a metal detector, automatic back-flushing screen changer and a hot-die-face, water ring-type pelletizer.
Erema's patented recycling technology feeds scrap into a large vertical cutter/compactor that uses friction to compress, size reduce and pre-warm the plastic. The heated, densified material is then fed directly to the extruder screw.

Colortronic rolls out its latest auxiliaries
Colortronic North America Inc. of Flint, Mich., has introduced several products:
* The CFC Weigh Hopper, used for single-material applications.
The unit eliminates funneling for consistent and accurate flow of all free-flowing materials.
Colortronic mounts the CFC on a precision load cell, eliminating the weight and vibration of the metering auger and motor assemblies.
The CFC's extrusion control system tracks extruder screw speed, then adjusts the extrusion line haul-off speed, so the product weight remains consistent to the length.
* The CGC series blending and feeding system for continuous extrusion. The weigh hopper learns the extruder rate and automatically adjusts the upper material feed rates to match the learned extruder rate, maintaining a consistent ingredient ratio. Upper material supply hoppers with conical reload valves are standard.
* The Windows-based CoExpert system can control extruder speeds and layer percentages, and stores recipes for up to six extruders.
* The CIT series inventory monitor units keep track of batch weight and density. A weigh hopper is available with a dump valve and a slide gate.

Munson's Maxum 30 shreds with few fines
Utica, N.Y.-based Munson Machinery Co. Inc. said its Maxum 30 shredder reduces large blocks and bales of material into particles with a narrow size range that have minimal fines.
Each of two rotors is configured with solid carbide tips, arranged in staggered fashion. The conical tips fit into receiver slots for quick replacement.
The counter-rotating shafts can grind blocks measuring up to 2 feet by 2 feet by 6 feet and weighing as much as 1,600 pounds. The two 14-inch diameter shafts rotate at 25-35 revolutions per minute.
The unit is equipped with two direct-coupled, shaft-mounted gear reducers.

InteliMotion speeds robotic sequences
Automated Assemblies Corp. has earned a U.S. patent on its InteliMotion process that automatically enables robots to operate at the fastest-possible motion sequence, without the involvement of an operator.
InteliMotion is available on all of Automated Assemblies' Raptor robots.
The company in Clinton, Mass., developed the process after market studies showed the need to determine the payload of the robot and adjust the movement of each motor automatically.
