Pelletizers and dicers.

AEC, INC.

Offers two series of strand pelletizers: slant-cut ER series for engineering resins and Standard series with advanced sound control.

BERINGER LLC 

WRP water-ring pelletizing systems feature a hot-cut, water-ring die-face system that minimizes sensitivity to process conditions. Dry die-face cut and water-ring pellet quench do not freeze or slow the flow of polymer through the die. Easy start-up and low energy consumption achieved because knife assembly cuts molten polymer in air instead of cutting a semi-molten extrudate underwater or a hardened strand.

Each cutting blade individually flexes and adjusts to the die-plate surface. Centrifugal dryer removes surface water from pellets. Fast cleanout. Throughput rates from 500 to 5000 lb/hr.

BERLYN EXTRUDERS INC.

Strand pelletizers with capacities to 5000 lb/hr and underwater pelletizers with cooling and dewatering devices. Hot-face cutters with capacities to 5000 lb/hr.

BROWN PLASTICS ENGINEERING CO., INC.

Strand pelletizers for small production, laboratory, or school use have a 2-in. face with driven pull rolls coordinated with a driven rotor. Plain or stainless steel. Also rebuilds pelletizers.

CALIFORNIA PELLET MILL CO.

Pellet mills from 2 to 500 hp for repelletizing scrap thermoplastics. Units operate by compressing fluff between two rotating steel rollers and a multiple-hole die. Frictional heat softens material so it coheres. Pellets are cut to length by adjustable knives. Bulk density of original fluff increases four to eight times. Pellet lengths and diameters can vary. Capacities from 500 to 18,000 lb/hr.

CONAIR

Strand pelletizers, which suit material ranging from standard grades to low-viscosity engineering resins and those with glass reinforcement, are available with rotor diam. from 6 to 12 in., widths from 4 to 32 in., and capacities from 500 to 34,000 lb/hr. T-Series and S-Series feature easy-access cutting chambers for simplified maintenance and cleaning. Metric series built with European drives and performance standards.

Waterslide pelletizing systems with throughput rates as high as 25,000 lb/hr use an inclined water conveyor to condition strands prior to dry or wet cutting by a strand pelletizer. Systems improve cut quality and minimize dust and fines. Units include a self-threading feature to ensure fast startup and minimize waste and strand breakage. Strand dies, pellet dryers, classifiers, and transfer systems can be supplied with units.

Regional service centers ensure fast response to repair, sharpening and spare parts needs.

DAVIS-STANDARD LLC

Underwater pelletizer systems from 500 to 10,000 lb/hr. Melt flow is directed through a die plate with cutting blades rotating in a vertical plane. Blades are driven by d-c scr drive. Drive shaft is aligned to maintain the blades squarely against the die-plate surface. Blades easily removed for sharpening or replacement. When reassembled, precise alignment of blades against the cutting face is said to be preserved. Complete assembly includes pelletizer and drive, spin dryer, water filtering and tempering system, and, if necessary, hot-oil system for die plates.

Also six models of underwater pelletizers and three models of water-ring pelletizers handle rates from 50 to 120,000 lb/hr for all types of polymer materials. Small systems for reclaim, product development, and testing. Ultra-high concentrations of pigments and very high or broad range melt indexes can be handled.

WAYNE MACHINE & DIE CO.

Yellow-Jacket heavy-duty strand pelletizers for laboratory and production applications in two- and three-in, models, which have eight-tooth steel straight or helical rotor. Both models feature a four-sided bed knife, which can be turned four times before requiring replacement. Other features are d-c drives from 1.5 to 5 hp, gear drive on rubber and knurled rollers for positive strand movement, easy clean-out, locking casters on stand, and 45[degrees] dump chute.

An option to the standard pelletizer that allows the pelletizer to produce micro-pellets as small as 0.010 in. and to continuously adjust up to 0.19-in. pellets. This is accomplished by using a master reference ratio drive system that controls the ratio of the cutter speed to the nip roller speed. Pelletizer line speed can be adjusted faster or slower while maintaining constant pellet length. In this case, the drive used on the nip rollers is 0.25 hp, while the drive on the cutter remains 1.5 hp.
