型砂的气力输送试验,从一九六六年四月二十五日成立试验小组起至八月三十日,经历120多天的奋战,试验基本上结束了.在实践过程中,经过了第一个阶段总长56米、第二阶段总长80米的两个阶段,共试验了310多次,初步摸索到气力输送型砂的一般规律.型砂气力输送试验成功,是活学活用毛主席著作,在“用”字上狠下功夫的结果,是高举毛泽东思想伟大红旗的胜利.型砂气力输送的出现,将促使型砂输送机械化进入新的发展阶段.
The pneumatic conveying test of sand, from the test team set up on April 25th, 1966 to August 30th, went through more than 120 days of hard work. The test was basically over. In practice, after passing the test, The two phases of a total length of 56 meters and a total length of 80 meters in the second phase were tested for more than 310 times. The general rules for pneumatic conveying of sand were tentatively explored. The success of the sand pneumatic conveying test was the work of Chairman Mao in the use of Chairman Mao. The result of “using” the word is a victory for holding high the great red flag of Mao Tse-tung’s thought. The emergence of sand-type pneumatic conveying will promote the mechanization of sand transportation into a new stage of development.
