Description
В известных конструкци х отечественных углеразмольных вентилируемых цилиндрических шаровых барабанных мельниц (ШБМ) примен етс брон волнистого профил с расположением волн по образующим , параллельным продольной оси барабана.In the well-known structures of domestic coal-milled, ventilated cylindrical ball-type drum mills (SBM), a bronze profile is used with an arrangement of waves along the generatrix parallel to the longitudinal axis of the drum.
Недостатками такой брони вл ютс : а) недостаточна производительность мельниц, б) высокий удельный расход электроэнергии и металла .The disadvantages of such armor are: a) insufficient productivity of the mills, b) high specific consumption of electricity and metal.
Шевронна брон дл шаровых цилиндрических мельниц, выполненна согласно изобретению, лишена этого недостатка. .Chevron armor for cylindrical ball mills made according to the invention is free from this disadvantage. .
Сущность изобретени заключаетс в том, что, с целью повышени производительности мельницы и снижени удельного расхода электроэнергии и металла, волны брони расположены таким образом, что они со стороны входной и выходной половин- барабана направлены навстречу друг другу. Пересекаютс волны в середине барабана, причем угол наклона их к продольной оси барабана близок к углу естественного откоса стальных (мелюших) шаров.The essence of the invention is that, in order to increase the productivity of the mill and reduce the specific consumption of electricity and metal, the waves of armor are arranged in such a way that they are directed towards each other on the input and output half of the drum. Waves intersect in the middle of the drum, and their angle of inclination to the longitudinal axis of the drum is close to the angle of repose of the steel (miniature) balls.
На чертеже изображена схема шевронной брони, вид с торца и в разрезе по продольной оси барабана.The drawing shows a diagram of chevron armor, view from the end and in section along the longitudinal axis of the drum.
При предложенном расположении волн шарова загрузка при подъеме будет перемещатьс в среднюю часть барабана, т. е. к месту наибольшего скоплени топлива. Пада вниз, шары будут также перемещатьс вдоль горизонтальной оси барабана к входной и выходной горловинам , увлека за собой топливо. При этом возникнет циркул ци шаротопливной загрузки вдоль оси барабана, улучшающа распределение топлива между шарами.With the proposed arrangement of the waves, the spherical loading during lifting will move to the middle part of the drum, i.e. to the place of the greatest accumulation of fuel. Falling down, the balls will also move along the horizontal axis of the drum to the inlet and outlet necks, carrying fuel away. In this case there will be a circulation of a balloon fuel load along the axis of the drum, which improves the distribution of fuel between the balls.
