|Plastics-Recycling Granulators Offer Improved Efficiency
SMITHFIELD, RI — Herbold Meckesheim horizontally fed granulators are quieter and more efficient than gravity-fed size-reduction equipment. Designated the SB Series, the five new models granulate containers made of Polyethylene Terephthalate (PET) and other recyclable plastics at rates of up to seven tons per hour.
Materials to be size-reduced are often a hodgepodge of sizes and shapes. The many advantages of SB Series granulators stem from their horizontal feeding screws, which force materials from the hopper to an adjacent cutting chamber at a steady, even pace instead of depending on the materials to fall directly into the blades. One result is higher throughput — an improvement of 30-50% compared with same-size gravity-fed cutting chambers. Other benefits include less power consumption, quieter operation, no fly-back, reduced wear to the cutting blades, and reduced fines and dust (since granulated particles spend less time in the cutting chamber).
SB Series granulators are suitable for dry or wet operation and can also be used for secondary size reduction of pre-shredded plastics.
Herbold Meckesheim USA, a subsidiary of Herbold Meckesheim Germany, designs, manufactures, and installs size-reduction equipment (shredders, granulators, etc.) and wash-line systems for the plastics industry, specializing in the recycling of industrial and post-consumer plastics.
