S1118—I和S1118两种规格相同而传动系统不同的辗轮式混砂机,分别于一九八一年十一月与十二月在江苏江阴铸造机械厂和广西八步铸造机械厂厂级鉴定通过。它们是一九八○年由一机部济南铸锻机械研究所主管设计,山东工学院参加,按照JB2656—79辗轮式混砂机基本参数标准,运用模块化设计原理和价值工程的方法,总结国内十多年来研制混砂机的经验和教训,在参数上作了大量实验,结构上
S1118-I and S1118 two specifications and the same transmission system of different rolling wheel mixer, respectively, in November 1981 and December in Jiangyin, Jiangsu Casting Machinery Plant and Guangxi eight-step foundry machinery plant level Appraisal passed. They are in 1980 by a machine designed by Jinan Casting Machinery Research Institute, Shandong Institute of Technology to participate in, according to JB2656-79 roller wheel mixer basic parameters of standards, the use of modular design principles and methods of value engineering, Summarize the experience and lessons learned in the development of sand mixer for more than a decade in China, and make a large number of experiments on the parameters
