Reduction Engineering Scheer Inc.'s new Bullet Series of strand pelletizers offers flexibility for quick material changes.
The Bullet blends the cutting geometry of the Conair model 304 pelletizer with the easy-access design of Scheer pelletizers, according to Reduction Engineering.
Reduction introduced the Bullet at the Plastimagen trade show, held Oct. 4-7 in Mexico City. The company plans to show the pelletizer at NPE in April in Orlando, Fla.
The new pelletizer comes in three sizes: the Bullet 62, which can run up to 300-400 pounds an hour; the Bullet 64, which handles up to 600-800 pounds an hour; and the Bullet 66, which runs up to 900-1,200 pounds an hour.
Kent, Ohio-based Reduction Engineering purchased the Scheer pelletizer business in Stuttgart, Germany, in 2008. Reduction made rotors for and assembled Conair pelletizers, then later bought the Conair line.
“We have merged proven designs from Europe and the U.S. to deliver a next-generation unit that provides user-friendly features, fast turnarounds and high efficiency,” said Tom Kernstock, product manager for Reduction Engineering Scheer.
Kernstock said the Bullet is designed for laboratory work and lighter production runs, including compounds and color concentrates.
“You don't want a pelletizer that takes 15-20 minutes to change,” Kernstock said. “This is something that Scheer was known for — quick changes. Some of these smaller color concentrate makers change materials two or three times an hour.” Often, they will make five or six changes a shift, he said.
Features include a pivoting upper nip roll and a pneumatic cylinder that can be easily moved out of the way. “It gives you more access to the cutting chamber,” Kernstock said.
The tool-less removable in-feed and discharge chutes also make fast changes easier.
A single, large pneumatic cylinder keeps the upper feed roll parallel with the bottom roll. That produces a greater uniform pulling force, with varying-diameter strands, for less waste, according to Reduction Engineering Scheer.
