在冶金矿山生产中,要求粗碎矿仓保存一定高度的矿石,使来矿不直接接触运输设备(如链板运输机),避免大块矿石砸坏设备。过去无检测仪器,运输设备常被矿石砸坏,影响生产。遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的伟大教导,根据援外项目和国内生产上的需要,我们克服各种困难,经过不断改进,研制成功LWJ-4型γ射线料位计。该仪器在国内一些厂矿,如河北铜矿选矿厂等进行了试用,生产实践表明,效果良好,受到操作工人欢迎。该仪器进行料位测量时,具有不接触物料、可以长时间连续工作和使用寿命长、灵敏
In the production of metallurgical mines, crude ore mines are required to store a certain amount of ore so that the mined ore does not directly contact transport equipment (such as chain conveyor) and large-scale ores will not be damaged. In the past no testing equipment, transport equipment often smashed ore, affecting production. According to Chairman Mao’s great teaching on “We must break the routine and try our best to adopt advanced technology”, according to the foreign aid projects and domestic production needs, we overcome various difficulties and, through continuous improvement, developed the LWJ-4 γ-ray level meter . The instrument in some factories and mines, such as beneficiation of copper mines in Hebei and other trials, production practice shows that the effect is good, welcomed by the operating workers. The instrument for level measurement, with no contact with the material, you can work long hours and long life, sensitive
