Xingnong brings you relevant reports on wet ball mills

In the past, it was believed that the energy utilization rate of ball mills was only less than 10%. It is proposed to evaluate the ball milling efficiency based on the new surface area generated per unit energy of a single sample under compressive load or impact load. Taking the average value of single particle crushing under compressive load as the basis for efficiency calculation, it can be concluded that the ball milling efficiency of quartz is approximately. The calculated surface area of the single particle test is used as a reference, and the ball milling efficiency of soda-lime glass is within the range. Compared to the energy required to break a single particle to produce the same degree of particle size distribution, the net efficiency of batch ball milling of soda-lime glass is approx. In addition, the energy utilization rate can be almost doubled by using the scattered pieces after crushing for re-crushing. When the closed-circuit grinding process is adopted, the cycle load increases from 1 to 2, and the energy utilization rate can be improved. When conducting the ball milling power price index test, if the test particle size is fine (smaller than the screening efficiency), the test results will be too large. For this reason, the Canadian company uses the wet ball milling power index test instead of the standard dry Test method. The equipment and media, equipment and process parameters used in the wet test are basically the same as the standard method, but water must be added to the mill barrel to make the slurry solid volume concentration reach. Since the wet grinding efficiency is higher than that of dry grinding, the measured The work index must be multiplied by the efficiency correction coefficient.
Currently, the world's largest wet ball mill is the Ф ball mill ordered by the Chilean Copper Mine in 2015. It is driven by a ring motor and has an installed power manufactured by the group. The world's largest dry ball mill, the company's Ф ball mill, is driven by a ring motor. It was used in a gold mine in the United States to process refractory gold ore.
The largest wet-type ball mill currently used in China The ball mill
is an overflow ball mill of the Ansteel Diaojuntai Mineral Processing Plant. It is manufactured in the United States by the original Swedish company, and some parts such as the cylinder are manufactured in China. Its power is, effective volume, rotation speed, and rotation rate. This equipment The test run started in March and was put into production in March. The largest wet ball mill designed and manufactured in China is the Ф overflow ball mill with an installed power of 100,000 square meters. It is used in Tongling Nonferrous Metal Mountain Concentrator Plant and is installed in 2017.
