Compounding & mixing.

Throughput capacities are going up for compounding equipment of all types. Higher outputs generate more heat, so you'll also see lots of equipment with enhanced cooling. Above all, you'll see a lot of unconventional approaches to compounding that bear little resemblance to traditional mixers or twin-screw compounders. Many are designed for very high levels (80% to 85%) of mineral fillers or wood flour. Filler levels are rising because of the high cost of resin.

The latest development in Buss's Quantec high-output kneader is an output-raising retrofit for older Buss machines in which a Quantec section, with four rows of barrel pins and four overlapping flights, replaces the mixing section with three rows of pins and three non-overlapping flights. The retrofit raises the kneader's output by 20-25%.

Leistritz's first North American show of its Maxx twin-screw extruder offers 30% more free volume plus enhanced cooling for higher output. Littleford Day is showing an LR 5500 cooler for the first time with a 90-psi-rated cooling jacket to allow increased water circulation. Cooling jackets are typically rated for under 15 psi. Littleford's high-intensity mixer is also displayed with dual discharge, allowing it to feed PVC premix to two coolers instead of one for even higher throughput.

Farrel's CP100 continuous mixer has a drive upgrade that allows higher filler levels--up to 80%. List has a twin-shaft kneader/reactor that can add up to 40% filler to silicone gum. List says it's the only system that can do that.

Many extruder OEMs show new modular construction approaches to offering customized features more affordably. Entek's modular E-Max co-rotating twin-screw machines can be easily lengthened by adding prefabricated frame extensions. Coperion's new ZSK 32 MEGAcompounder Plus is built of modules in a frame.

Chinese connections are another route to building compounding machines more affordably. Coperion, which acquired Keya in China, will show Keya's export-model twin-screw extruder here for the first time. Two exhibitors are Chinese machine builders with European connections. Nanjing Giant Machinery is an ISO-9001 joint venture with Pomini in Italy. It offers co-rotating twin-screw extruders, gravimetric feeders, and a new gear pump.

Guangdong Liansu Machinery is a joint venture with Dressbom GmbH, a German PVC consultant, offering conical and parallel twin-screw extruders and PVC mixing and pelletizing equipment.

More wood in WPCs

News in wood/plastic composites (WPCs) includes the first exhibits of several two-stage mixer-extruder combinations that yield very high wood content and start with undried flour. Lodige/Pappenmeier's WPC compounding process uses a TSHK friction-heating mixer to coat 85% wood flour with 15% PP. The mix discharges into an HKB horizontal cooling mixer, which produces free-flowing crumbles ready for extrusion.

Draiswerke is showing a 300-hp Gelimat G25S thermokinetic mixer with increased cooling capacity to mix up to 85% mineral filler or wood-flour at up to 2000 lb/hr.

Pallmann Pulverizers is showing its unusual Palltruder here for the first time. A mid-sized PFV 400 processes up to 2500 lb/hr. It combines a single-screw frictional-heat mixer with a die plate and granulator knives to produce free-flowing granules containing up to 85% wood.

News in testing and controls

Several test devices at the show were developed for the new European DIN-EN 13900-5 standard for melt dispersability of color compounds and masterbatches. The standard is known as the Filter Pressure Value (FPV). Exhibitors with FPV test equipment include Dr. Collin, LabTech, and Davis-Standard.

Speaking of color, JSW and FACTS Inc. are using in-line color analyzers to detect color variances and--on a developmental basis--to control letdown of colorants in an extruder. FACTS is showing a new non-contact spectrophotometer from X-rite with FACTS software for closed-loop control of color feeding. JSW is using an Equitech in-line color analyzer.
