Durand, based on his data (pipe diameter varying from 0.02 m to 0.6 m, particle sizes from 0.0001 m to 0.025 m and pipe velocity from 0.6 m/s to 6 m/s) proposed the following equation for

A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out. Due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene (HDPE), or manufactured completely from HDPE … WebbOver the decades, the flow of slurries through pipelines had been a common practice for various industries such as the oil and gas, food, pharmaceutical, solid handling, tailing, and even power generation. Many factors affect slurry flow behaviour in pipelines.

WebbThe pipe flow of slurries is important in many industries, especially in the mining industry, but also in the dredging, power generation, agricultural, sewerage and other industries. A slurry is here defined as a mixture of non-dissolvable solids in a liquid, with the liquid usually being water.

WebbGuidelines for an Effective Slurry Pipeline The slopes of the horizontal line should not exceed the angle of repose of slurry.
