目前，我国煤炭储量居世界第二，产量居世界第一。但我国的原煤入洗比例我国仅２３％左右，而发达国家均在５０％以上，个别达到９５％。因此，开发先进的选煤工艺和设备，特别是开发适合我国国情（难选煤比例多）的重介选煤设备尤为重要，我们引进美国丹尼公司浅槽选机的经验
At present, China has the second largest coal reserves in the world and the largest output in the world. However, China’s raw coal washing only about 23% of our share, while the developed countries are more than 50%, individually 95%. Therefore, it is particularly important to develop advanced coal preparation technology and equipment, especially for the development of heavy medium coal preparation equipment suitable for China’s national conditions (with a large proportion of refractory coal). We have introduced the experience of Danny Shallow Slot Machine
