Abstract:

There are given the results of development of two-stage jet mill for grinding of coal-tar and petroleum pitches for "Ogneupory" JSC (Bogdanovich, Sverdlovsk Oblast, Russia). Pitch is used as the binder additive during the manufacturing of refractory products. It should be noted that pitch can not be ground in the traditional mills, because it is a thermolabile material with excellent adhesion. High rates of air flow in the jet mill cause the high heat transfer coefficient from the particles to the gas stream. This makes it possible to avoid the material heating during the grinding. Coarseness of initial material is up to 5 mm. At the same time, coarseness of finished product is less then 300 mkm. The calculation methodology of grinding process is developed, along with experimental researches. There is developed the design of a jet mill with productivity of 60 kg/hour, including two ejectors with supersonic nozzle and gas purification system. There are given the results of adjustment, optimal constructive and operational parameters. Implementation made it possible to solve the difficult technological problem of pitch grinding.
