陕西铜川耐火材料厂职在技术革命运动中用废料试制成功一种新型压砖机——东风牌冲击式双模压砖机。经过试生产证明效果良好,现已正式投入生产。这种双模压砖机的优点是:①效率高质量好,每台机器3人操作,每天能生产标准型耐火砖坯28吨多;所成型的砖坯的质量完全合乎标准。②构造简单 Shaanxi Tongchuan Refractory Materials Factory successfully used waste in the technological revolution to successfully manufacture a new type of brick press, the Dongfeng brand impact type dual-press brick machine. After trial production proved to be effective, it is now officially put into production. The advantages of this dual-mode brick press are: 1 The efficiency and high quality are good. Each machine can operate with 3 people. Every day, it can produce more than 28 tons of standard refractory bricks. The quality of the formed bricks is completely in line with the standard. 2 simple structure
