  • Wet Grinding of Coal in the Szego Mill: Limiting

    A dynamic wet-grinding model recently developed for the Szego Mill is reviewed. Use of this model allows a priori predictions of limiting performance for all design and operating variables in the “paste grinding” regime, i.e., at relatively high solids concentrations which are optimal for wet grinding in the Szego Mill. Limiting size

  • Fine grinding of mica in the Szego Mill ScienceDirect

    1/3/1990· Some data on wet grinding of coal in Szego Mills of different sizes were also given, and residence times in the mills were shown to be short, 2 5 s in the laboratory mill and up to 20 s in commercial-size mills. The objective of this paper is to describe the performance of the Szego Mill in both dry and wet grinding of mica. The effect of mill rotational speed is examined over a number of

  • Characterization of Szego-milled Hemp Fibers

    A series of tests has been conducted grinding hemp with the SM-220 Szego Mill equipped with three helically grooved, 30 cm long rollers with 8*8 or 4*4 mm grooves. A range of flow rates and rotational speeds has been covered in both dry and wet operation to determine the best processing conditions for various potential applications of refined hemp fibers. Particle size distributions and power

  • The Szego Mill® A new high-efficiency grinder offering

    26/3/2019· Toronto, March 26th, 2019 — Szego Materials Engineering Inc. has begun production of The Szego Mill, a high-efficiency industrial grinder using technology and methods unique in the world of comminution. It offers significant cost savings, with 30x greater volume capacity of a similar-sized ball mill, using up to 10x less power. The Szego Mill is a modular unit and allows tool-free

  • Studies of grinding of wood and bark-wood mixtures with

    Abstract (summary): The grinding of various woody materials in the Szego Mill, a unique ring-roller mill, was studied. Wood wastes consisting primarily of bark, and aspen chips were ground dry, and jack pine sawdust was ground wet. Mill performance was determined by measuring particle size, characterized by the 80%-passing size ('x'80), and mill power, from which is derived the specific energy

  • Grinding of coal‐oil slurries with the szego mill, The

    A comparison of different wet grinding mills was given by Hatano (1978), but in general published data on mill performance for wet grinding in oil are rare. In this paper a first systematic set of results on grinding coal in oil with the novel Szego mill is presented and is a contribution to the general knowledge of wet grinding in non-aqueous media. It is partially based on material presented

    The biomass was milled with the Szego Mill™ using three different approaches: dry milling, wet milling and for the first time nitrogen assisted wet milling was tested. Bioethanol and biogas

  • Biomass Pretreatment with the Szego Mill™ for Bioethanol

    The biomass was milled with the Szego Mill™ using three different approaches: dry milling, wet milling and for the first time nitrogen assisted wet milling was tested. Bioethanol and biogas production were studied, but also fibre analysis and SEM (scanning electron microscope) analysis were carried out to characterize the effect of different milling approaches. In addition, two different

  • Modified oil agglomeration process for coal

    A Szego Mill was used to wet grind Minto (New Brunswick) coal which was then subjected to laboratory agglomeration by the NRC procedure. A comparison with coal ground in a ball mill indicated superior ash rejection. The improved performance is attributed to better mineral liberation which is enhanced by the more flaky particles produced in the Szego Mill. Abstract fr. La technique de l

  • SM App: Mineral Processing General Comminution

    Softer minerals (having Mohs hardness up to about 5) are suitable for wet or dry grinding in the Szego Mill. Harder minerals such as quartz may be ground, but wear on the grinding surfaces is high. Efficient size reduction for talc, mica, limestone, and quartz has been demonstrated in pilot mill work with the Szego Mill. Mineral Processing. Mica Grinding Mica flakes are used to increase

  • :: A Better Way to Grind Ore? A Conversation with David

    David Szego: What we have is an industrial grinding mill. Anybody can buy a mill, and it’s an intrinsic part of the recovery process, but The Szego Mill has a few specific characteristics that no other kind of milling or grinding technology can offer. These will come into play when you are processing the ore to make the final product, which is quite a-ways down the line from the early
