These knife pulverisers boast a high number of revolutions, come equipped with rotating and bed knives, and are capable of fine-grinding cellulose to a fineness of d99 (63 microns). Feeding is via gravity (cellulose sheets) or via a roller feeding device (bales). The resultant fineness is determined by the size of the screen holes.
Through intensive research, Herbold has succeeded in developing the machines to the extent that they can achieve a fineness that, until recently, was possible only with complicated multi-step procedures. Main advantages of the SMF pulveriser design are its high cutting rate between rotor and stator knives and the optimal cooling system of the machine, according to Herbold. The air stream of the suction unit is used as a cooling medium while the body of the pulveriser is tempered with the help of a water-cooling device.
Extremely fine cellulose can lead to an explosion of dust. Therefore, Herbold not only supplies single machines but also complete turn-key units designed to prevent major dust emissions. The same approach can also be used successfully for the fine-grinding of textile and synthetic fibres, as well as for the production of fillers and powders for manifold applications in the food industry, in the chemicals sector, and for additives for the building industry.
Herbold services the U.S. and Canadian markets through its subsidiary Resource Recycling Systems of Smithfield, Rhode Island (www.resourcerecycling.net).
