Granulator series features three models
T50: The three models in this series of granulators from Cumberland are designed to chop up large parts, including injection molded, blow molded and extruded scrap; film and sheet; and automotive moldings, ducts and components. With many optional features and two configurations for the precision-tolerance cutting chamber, the granulators can be tailored to handle products of different densities, wall thicknesses and sizes. Cumberland offers abrasion-resistant packages for high-wear applications and a water-cooled rotor option that limits heat generation. The granulators feature an intelligent control system with a 7-inch, intuitive color touch screen for easy operation. Network connectivity provides remote access to the machines. Throughputs range from about 1,500 pounds per hour to 2,500 pounds per hour.
What’s new? The line of granulators, which debuted in July.
Benefits: Versatility, high-quality regrind and an easy-access design that saves energy and simplifies maintenance. Bed-knife maintenance is easier because operators no longer need to hold the bed knife and the shield at the same time. Additionally, each granulator door has safety features that ensure the rotor is stopped before the door can be opened. The cutting chamber and hopper suppress noise.
Padlock promises extreme durability
HD Type P padlock: Designed for use in harsh environments like recycling facilities, the HD Type P padlock can be integrated into lockout/tagout procedures within a trapped-key, interlocking safety system. It is constructed of heavy-duty 316 steel with a 304 stainless-steel shackle, while the dowel pin key and cylinder are made from 316 stainless steel. As an option, companies can have an alphanumeric code of up to five characters stamped onto the lock and key for easy identification.
What’s new? The padlock, which was introduced in June.
Benefits: Extreme durability. The heavy-duty construction and materials make the HD Type P suitable for extreme industrial settings, and the key is gasketed to keep dust and debris out.
Shredder now available in more robust version
Heavy-Duty Modular Split-A-Part: This line of shredders from Republic Machine comes in 100-horsepower to 300-horsepower models, with rotor diameters of 15 inches and 20 inches and four cutting widths ranging from 42 inches to 72 inches. It features an overtorque limiting clutch assembly and offers easy access for cleaning and maintenance. Additionally, shredders in this line are equipped with a single-piece solid forged rotor and an adjustable anvil for maintaining tight gap tolerances. They also include bolt-in replaceable tool holders and reversible counter knives that can be resharpened.
What’s new? An even heavier-duty, 300-horsepower version, designed for a recycler that handles especially contaminated materials, including bags, baled film and strapping. To create the more robust shredder, which began shipping earlier this year, Republic Machine says it redesigned its 20-inch rotor and beefed up the company’s patented Zoidal cutting system, which is shown at right, using a unique metallurgy for the larger blades and holder.
