It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Sep 22, 2020· The issue of energy efficiency is one of the main one at any enterprise. The grinding process in the ball mill is highly energy intensive, because grinding process accounts for up to 45% of total energy consumption. It is not possible to estimate the power consumed by the mill drive without taking into account all the factors influencing the grinding process, such as Ball Mill :: L.V. TECHNOLOGY,Ball Mill. Ball Mill. This separation saves a lot in term of pressure drop across the separator as well power consumption.

seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 Net specific energy consumption of regrinding circuit.Modelling SAG milling power and specific energy,the mill power and the efﬁciency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or speciﬁc energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption but will not satisfy

the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is hardness, and other factors. Consumption is closely related to total ball charge surface area. • A useful guideline for make-up ball size for a new circuit was provided by Bond (1958).Energy Use of Fine Grinding in Mineral Processing,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.
