CHICAGO—Farrel Corp. displayed at NPE the largest unitized compounding machine it has ever built.
Its CP-2500 Compact Processor fills the gap between Farrel's other unitized compounders and its very large machines, Gene Sorcinelli, product manager for compact processors, said in an interview at NPE 1997, held June 16-20 in Chicago.
``This is as large as we can make for shipping as a single unit,'' he said.
The CP-2500's 600-horsepower drive powers the mixer portion of the machine and another primary motor with 300 HP drives the extruder stage. Mixer speed ranges from 535-700 revolutions per minute and the extruder runs at 74-103 rpm.
Sorcinelli said the compounder is suited to highly filled polyolefins, abrasive materials, elastomers and highly pigmented compounds. The machine includes user-friendly features such as a three-piece rotor and grease-packed bearings.
Farrel sold its first CP-2500 to Heritage Plastics, which bought its first Farrel compact processor in 1982. The latest extruder is Heritage's seventh Farrel line.
Farrel installed its most powerful FTX twin-screw extruder in its headquarters laboratory in Ansonia, Conn. The FTX-500H, with throughput of 4,400 pounds an hour, is available to compounding customers, the firm said. The machine has four times the throughput of its standard counterpart. It offers maximum installed power of 600 HP and maximum screw speed of 1,000 rpm.
Farrel is replacing a 37-millimeter twin screw at its lab with the FTX-80 it displayed at NPE. It also is adding a 68mm twin-screw model in Ansonia and at its lab in England.
