为了改变在建筑企业中用人工淋灰的落后面貌,以解放劳动力,减少矽肺病的发生,提高生产效率,我们遵照毛主席关于“独立自主、自力更生”的伟大教导,自己动手,利用边角废料,在一个多月的时间内,经过反复多次调试,试制成功一台轻便座式粉碎淋灰机(图1),并已经正式投产使用。初步查定比人工淋灰提高工效12～15倍。 In order to change the backward appearance of using artificial ash in construction companies to liberate the labor force, reduce the incidence of silicosis, and increase production efficiency, we follow Chairman Mao’s great teaching of “independent, self-reliant” and use our own scraps of waste. In a period of more than one month, after repeated trials and trials, a portable seat type smashing and ashing machine (Figure 1) was successfully manufactured and put into production. Initially determined to improve ergonomics 12-15 times than artificial lime ash.
