Broad Size Range
SCC Screen Classifying Cutters are offered in five sizes with model numbers denoting length in inches of the feed throat opening. The width of the feed throat is 11 inches for all models.
- SCC-10 (10 x 11-in)
- SCC-15 (15 x 11-in)
- SCC-30 (30 x 11-in)
- SCC-48 (48 x 11-in)
- SCC-60 (60 x 11-in)
- SCC-72 (72 x 11-in)
Parallelogram Cutters Minimize Power Requirements
The SCC rotor assembly is comprised of inter-connected parallelogram cutters arranged in a progressive configuration to stagger the distribution of rotational torque. Whereas conventional knife cutters rely on a simultaneous cutting action over the entire length of the cutting knives, the staggered blades of the SCC cutter impart six times more force per inch at the instant of cutting than comparably sized knife-type cutters of equivalent horsepower, providing more thorough reduction of such hard-to-reduce materials as fiberglass, tough hydrocarbons, Aramid® fiber and fiber reinforced plastics.
Parallelogram cutters are fabricated from a select grade of tool steel, and are heat-treated for greater strength and longer life. They can be sharpened in minutes with a minimal removal of material. To sharpen, the parallelograms may be stacked, thus allowing all to be sharpened simultaneously in a single operation.
Staggered cutting instantly creates a major granulated reduction of product that minimizes retention period within the cutting chamber and assists in reducing the percentage of fines. Thereby increasing the rate of throughput. Conventional knife cutters often shear product into strips that are retained until the knives can further reduce these strips.
Spiral Feeding Effect
The parallelograms are pre-drilled and self-aligning. Their cutting sequence creates a natural spiral feeding effect, moving the material from the ends of the cutting area and toward the center. This action greatly reduces the possibility of material becoming trapped between the shaft and end plates. If desired, the parallelograms may be arranged to feed the material in a right-hand or left-hand direction within the cutter, or in a non-directional, intermittent fashion.
Stationary Bed Knives
Bed knives are secured to solid anvils to prevent movement. Bed knives feature reversible cutting edges that double their functional life. They are easily accessible from the outside of the cutter housing for quick removal or adjusting. The bed knives are adjustable to compensate for sharpening and wear on the parallelogram cutters.
Bedscreen Size Determines Finished Output
Munson can furnish classifying screens in a variety of sizes to suit customer requirements. The screens are available with round perforations from 1/32" to 1½" diameter, and with special square perforations (typically for fiberglass) on request. Screens are held securely in place by a quick-release support mechanism for rapid removal and replacement.
