澳大利亚艾比肯太平洋公司开发了一种应用激光扫描技术和气阀的选煤新工艺,采用此工艺可比传统工艺节约成本30%以上.据该公司预测,该项选煤新工艺在今后二十年将取代传统的洗煤工艺.应用科罗里斯堪激光选煤技术只需很少量的水用于抑制粉尘,对于有优质资源又距水源很远的昆士兰和新南威尔士地区的煤矿,不仅能降低煤炭洗选成本,而且能获得市场竞争的优势. 激光选煤新技术的原理是在一个独特设备中,原煤通过一级或二级破碎成-50mm.将破碎煤筛分成50～30mm、30～10mm和- 10mm三部分.激光选煤处理前两种粒度大些的煤十分理想.碎煤从破碎机进入带一定角度且有抗磨衬垫的斜溜槽,再送往5.5m长的胶带输送机.胶带迅速移动,破碎的煤从头顶上一个激光扫描器和一个滚筒之间通过.激光扫描速度为1000次/s,能量测煤炭反射光的数量;在预先设定的技术条件下工作,鉴别煤炭的灰分.
Abacus Pacific Australia has developed a new coal preparation process that uses laser scanning technology and gas valves to save more than 30% of the cost of a traditional process, according to the company’s forecast that the new coal preparation process will operate in the next two decades Will replace the traditional coal washing process.Application of Korolliscan laser coal preparation technology requires only a small amount of water used to suppress dust, for good resources and far away from the source of water in Queensland and New South Wales coal mines, not only can reduce Coal washing costs, but also to obtain the advantage of market competition.Laser coal preparation technology is the principle of a unique device, the raw coal through the primary or secondary crushing into -50mm.Screened coal is divided into 50 ~ 30mm, 30 ~ 10mm and - 10mm three parts.Laser coal preparation before the two larger particle size coal is very ideal.Coal from the crusher into the angle with a wear-resistant inclined chute chute, and then sent to 5.5m long tape delivery The tape moves rapidly and the shredded coal passes between a laser scanner and a cylinder overhead with a laser scanning speed of 1000 cycles / s, which measures the amount of reflected light from the coal; under pre-defined technical conditions As, identification of coal ash.
