接纳二手反转展转窑、二手球磨机Recycling used rotary kiln, used ball mill

1、本公司临时低价接纳二手反转展转窑、二手压力机、二手煤气星力手机捕鱼、二手球磨机、二手脱硫塔、二手脱硝塔、二手湿式电除尘设置装备摆设等设置装备摆设,要求:设置装备摆设八成新以上,电器配件完全,由正轨厂家的出厂及格证,有装配园地,没有经济纠纷等,联络德律风:86-13676907460

2、 球磨机的转速每时每刻影响这球磨机研磨介质和物料的活动形态,并且,由于转速的变革,研磨介质和物料做着差别的活动,在差别的活动形态下,球磨机的破坏服从也在发作着变革。球磨机内的研磨介质与物料按球磨机转速的差别,可以分为以下三种活动形态:泻落式活动;抛落式活动;离心式活动。球磨机正常的任务形态为抛落式或泄落式活动。球磨机临界转速经历公式为式中n—球磨机的临界转速(r/min)D—筒体的内径(cm)

    经过实验与理论的察看剖析,越是接近球磨机筒体,研磨介质的量越大,充沛发扬最外层对物料的破坏作用,才干使球磨机设置装备摆设的服从做大。由实际盘算得知,最外层研磨介质的离开角为54.73°时,可以使最外层取得大的下降高度,对物料以最无效地破坏。从实践操纵中发明,当球磨机的任务转速调解来临界转速的0.75~0.85时,可以使研磨介质处于较高的下降高度。

1, the company's long-term high-priced recycling second-hand rotary kiln, used press, second-hand gas producer, second-hand ball mill, used the desulfurization tower, second-hand denitration tower, used wet electric equipment such as equipment, requirement: more than eighty percent of new equipment, complete electrical accessories, factory certification by normal manufacturer, remove the site, no economic disputes, etc., tel: 86-13676907460

2, the speed of the ball mill always affects the ball mill grinding media and materials of the state of motion, and, due to the change of the speed, grinding media and materials do different movements, in different motion state, the grinding efficiency of the ball mill is also changing.According to the different speed of ball mill, the grinding medium and material in ball mill can be divided into the following three motion states: falling motion;Drop motion;Centrifugal motion.The normal working state of the ball mill is drop or drop motion.The empirical formula of critical speed of ball mill is n -- critical speed of ball mill (r/min) D -- inner diameter of barrel (cm)

Through the observation and analysis of the test and practice, the closer to the ball mill barrel, the greater the amount of grinding medium, and give full play to the crushing effect of the outermost layer on the material, the greater the efficiency of the ball mill equipment.According to the theoretical calculation, when the separation Angle of the outermost abrasive medium is 54.73°, the outermost layer can obtain a large landing height and crush the material most effectively.From the actual operation, it is found that when the working speed of the ball mill is adjusted to 0.75~0.85 of the critical speed, the grinding medium can be at a higher landing height.
