粒料指散粒状固体物料。水力管送粒料是一种经济合理、技术先进的固体物料输送方法,在国民经济各部门有着广泛的应用。国内现时主要见于地下矿山输送充填料、选矿厂内的精矿和尾矿输送,水利部门输送泥沙等;国外更重要地是用于对煤炭、铁矿石、铁砂、铜精矿、石灰石、硬沥青、磷矿石等的长距离输送。国外一条管道年运量可达一千万吨以上,运距可达几千公里;其经验表明,水力管送的运费较新建铁路和已有公路汽车运输低得多,而且还具有不忌地形崎岖、基建快、不污染环境、不占用农田等
Granules refers to the granular material. Hydraulic tube feed pellets is a kind of economical and reasonable, advanced technology of solid material delivery method, has a wide range of applications in various sectors of the national economy. At present, it is mainly found in the transportation and filling materials of underground mines, the concentrates and tailings in concentrator and the transportation of sediment by the water conservancy department. The foreign countries are more important for coal, iron ore, iron ore, copper concentrate, limestone, Hard asphalt, phosphate rock, such as the long-distance transport. A foreign pipeline can transport more than 10 million tons a year and transport distances up to several thousand kilometers. Its experience shows that the shipping cost of a hydropower pipe is much lower than that of new and existing road vehicles, Rugged, infrastructure fast, do not pollute the environment, do not take farmland and so on
