May 08 2019 · the disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. most of the energy useless lost during ball mill operation, leading to low it efficiency. but even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
may 01, 2020 for example, atmaca and kanglu performed the first and second laws analysis of a raw ball mill in a cement factory to optimize the grinding process and decrease the consumption of electrical energy. the first and second laws efficiency and the electrical energy consumption of the rbm are specified to be 61.5%, 16.4% and 24.7 kwht
ball mill is suitable to grind various mineral and other materials, which is widely used in various industries such as benefication, construction materials, chemical industry, etc, the ball mill is a horizontal rotating device transmitted by the outer gear. the materials are transferred to the grinding chamber through the quill shaft uniformly.
dec 18, 2013 this quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 mw, while installed power for a sag mill can go up to 25 mw. however, the energy used for fine grinding is still significant.
jan 07, 2015 specific power consumption for clinkergypsum grinding in a ball mill should be approximately: 3000 24.4 kwht 3200 26.8 kwht 3400 29.4 kwht 3600 32.0 kwht 3800 34.7 kwht 4000 37.5 kwht note: the specific power demand of large grinding units is better than that of small mills. 8.1
