摘要

During this quarter,coal testing was initiated with Negri-Bossi No. V-12machine. The following conclusions were drawn from the testing to date. Various types and sizes of coal can be pumped against a back pressure of 1,500psig using a thermoset-type screw and taking advantage of the plasticizing properties of the coal. Coal properties with respect to temperature,pressure,and time are extremely important for the extrusion process and the extrudate quality. Systematic process parameters study is essential for the successful development of Dry Coal Screw Feeder. Special attention will be required in designing coal feeding and extrudate discharge areas.
