the szego grinding mill

Dec 31, 1993 New results from a systematic grinding study with the larger, SM 320 Szego Mill are reported. A wide range of flow rates, from 750 to 5300 kg/h of coal, at 60-65% solids concentration has been covered, with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured.

Fine grinding of mica in the Szego Mill ScienceDirect

Mar 01, 1990 The Szego Mill is a planetary ring-roller mill with radially mobile, helically grooved rollers. It has a high capacity for its size and is suitable for continuous dry or wet grinding, including pastes with high solids concentration. It reduces size rapidly, and with a relatively low power consumption. In this paper, results for mica grinding ...

Fine grinding of wood chips and wood wastes with the Szego

Results are reported of a study that shows that the Szego mill is capable of grinding wood chips and wood wastes to fine sizes. The effects of various feed, operating and mill design variables were investigated. The feed variables included the type of material and its moisture content. The operating variables included the mill rotational speed, and the rate of material through the mill.

Particle Shapes Produced by Comminution in the Szego Mill

Jun 01, 1995 The shapes of particles produced by comminution in the Szego Mill, a planetary ringroller mill, in different coal grinding operations show that particle shape is dependent on the type of operation, and help explain the breakage mechanisms. Dry grinding produces particles with a low aspect ratio due to interparticle attrition; significant briquetting of fine particles may occur.

Grinding of waste paper and rice hulls with the Szego Mill

Abstract Grinding of waste paper and rice hulls for use as reinforcing plastics fillers was studied using Szego Mills SM-220 and SM-320 in open circuit grinding as well as in combination with a high capacity classifier. Depending on how the fibres and the plastic are compounded, properties of the composite may or may not depend on particle size.

Floc flotation of Prince coal with simultaneous grinding

A novel idea, combining fine grinding and selective hydrophobic flocculation in a Szego mill, is presented to simplify the hydrophobic flocculation-flotation process for fine coal cleaning. In this simultaneous grinding and hydrophobic flocculation-flotation (SGHFF) process, the excess mechanical energy expended in grinding is utilized for mixing coal slurry, resulting in the formation of ...

Wet Grinding of Coal in the Szego Mill Limiting

May 16, 2007 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 predictions for the SM-320 mill and the conditions used are presented …
