Coke gives Herbold granulators a workout
Herbold Meckesheim GmbH supplied six SB-series forced-fed granulators to Coca-Cola Co.'s joint venture recycling plant in Spartanburg, S.C.
The equipment maker is based in Meckesheim, Germany.
Bottles in the storage hopper are fed horizontally into the cutting chamber with the help of feeding screws, which the company said increases the throughput by up to 50 percent. Power consumption is cut in half by using smaller motors. The cutting chamber is evenly loaded, so the granulator makes regrind with fewer fines and dust, and no fly-backs, Herbold Meckesheim said.
Coke opened the plant in January, together with its partner, Spartanburg-based United Resource Recovery Corp.

Clariant develops colors for PEEK resin
Clariant Masterbatches has developed a range of color masterbatches for polyetherether ketone resin.
The Muttenz, Switzerland, firm said PEEK can be very difficult to color. In its natural form it is light brown, so coloration needs to be taken into account. Also, PEEK usually is processed at more than 700° F, so colors need to be heat-stable.
Clariant's Renol color masterbatch series has more than a dozen standard colors designed for PEEK. Custom colors also are available. They meet stringent specifications in markets such as aerospace, military and medical, the company said.
Clariant's North American headquarters is in Holden, Mass.

New Arkema stabilizer designed for PVC pipe
Arkema Inc. has introduced cost-effective tin stabilizers for rigid PVC pipe.
The Philadelphia firm added two improved grades to its Thermolite tin stabilizer line. Thermolite 130 and 135 permit the use of a single stabilizer for pipe processes, offering the potential to lower overall tin content while maintaining quality, according to Arkema.
The new products can replace other stabilizers without altering process conditions. They provide high performance and consistent stabilization. Switching to a single stabilizer can produce savings by lowering inventory costs and reducing blending errors. Both additives have provisional approval for potable water applications.
Controller reduces motor energy usage
Power Efficiency Corp. offers a solid-state efficiency controller for electric motors that can cut energy use by up to 40 percent, depending on the application.
The Las Vegas-based company sold 28 of the E-Save motor-efficiency controllers to Berry Plastics Corp. The units are installed on 24 granulators at Berry's factory in Anaheim, Calif. The local utility ran tests and showed annual energy consumption will be reduced by more 195,000 kilowatt hours, cutting electricity costs for the plant by $17,600. That is an energy savings of more than 40 percent, and a payback on the investment in less than two years, Power Efficiency said.
Granulators are a major plastics machinery application, company officials said at the Plastics News Executive Forum, where Power Efficiency sponsored a one-day energy management workshop. The reason: Granulators run constantly but only grind, using a full load, when plastic is moved through. E-Save monitors the load on an electric motor and reduces the amount of power consumed by the motor when it is lightly loaded.
Sales director Gary Dusterhoft said Power Efficiency started out supplying its energy-saving controllers for escalators and elevators two devices that also are always running but carry big loads only periodically. Now the company is moving into industrial markets, including plastics, he said March 1 at the forum in Summerlin, Nev.
The patented E-Save technology uses a microprocessor and circuitry to sense a motor's energy requirements by monitoring both voltage and electrical current.
In February, Frost & Sullivan Inc. awarded Power Efficiency the American Constant Speed Electric Motor Technology Innovation of the Year Award.
Berry, based in Evansville, Ind., is working to reduce its energy consumption companywide, according to Ken Fritts, maintenance manager.
Dusterhoft said Power Efficiency has placed E-Save motor controllers at several other major plastics processors, including Graham Packaging Co. LP and Ball Corp.
Pipe extruder Charlotte Pipe and Foundry Co. also installed an E-Save at one of its factories.
