1996年11月9日,在比利时首都布鲁塞尔,第45届尤里卡世界工业发明博览会上“内通道矿石破碎机”荣获金奖同时,发明人李国桢被比利时王国政府授予“骑士勋章”。 内通道破碎机采用静压原理设计,矿石在通道内不受冲击,无跳动,无摩擦,噪音也很低,机器也不震动,耗能也很低,产量却很高,特别是破碎比最高可达100∶1。据测定,噪音由原来的200分贝下降到70分贝,节能50～70％,产量提高46％,设备无需固定,可节省基座投资。 继外电报道之后,1997年3月7日,中央人民广播电台播出了郑州晶海机械有限公司研制成功内通道矿石破碎机的消息。接着,《科技日报》、《中国机电
On November 9, 1996, at the 45th Eureka World Industrial Invention Expo in Brussels, Belgium, the “internal channel ore crusher” won the gold medal. At the same time, the inventor Li Guojun was awarded the “Knight Order” by the Royal Government of Belgium. The inner channel crusher adopts the principle of static pressure design. The ore is free from impact, no runout, no friction, and low noise. The machine does not vibrate and the energy consumption is very low. The output is very high, especially the highest crushing ratio. Up to 100:1. According to the measurement, the noise is reduced from 200 decibels to 70 decibels, energy saving is 50-70%, output is increased by 46%, and the equipment does not need to be fixed, which can save the investment in the pedestal. Following the foreign reports, on March 7, 1997, the Central People’s Broadcasting Station broadcasted the message that Zhengzhou Jinghai Machinery Co., Ltd. successfully developed the internal channel ore crusher. Then, Science and Technology Daily and China Electromechanical
