the ball mill not only has high investment cost, but also large energy consumption. the power of the ball mill directly affects the level of energy consumption. under the premise of ensuring the output, controlling the power of the ball mill within the rated range is the most important thing to save energy and reduce consumption and save cost.
planetary ball mill is a kind of ball mill that many consumers will choose. is the power consumption of this kind of ball mill large? in fact, there are many kinds of planetary ball mills in the ball mill market. the working efficiency and power consumption of each kind of ball mill are different.
typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 mw. the actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 1–5%. significant financial and environmental benefits can be obtained by improving this efficiency even slightly.
the combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. this demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in dem modelling.

the electric current for ball mill, enlarging the current is to increase the rotate speed. if the has high rotate speed, its work efficiency will be high. however, there is one notice: the increased current should be within the scope of the rated power range. otherwise, it will burn away ball mill. 2.
mill power usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. 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
a power analyser was utilized to measure mill power. increase in mill speed and ball filling leads to a remarkable increase in the amount of the power. preliminary results show that there is a definite trend between the power and the slurry filling u. mill power draw is maximum at slurry concentration 60–70% and slurry filling 0.84.
2.1 pengertian ball mill ball mill merupakan salah satu jenis mesin penggiling yang berbentuk silinder yang berfungsi dan digunakan untuk menggiling material keras menjadi material yang sangat halus. mesin ini biasanya digunakan dalam proses pembuatan cat, keramik, semen, kembang api, batu bara , pigmen feldspar dan serbuk material
specific energy consumption is the power draw of a mill (kw, usually corrected to the pinion or mill shell) or a sample from a transfer pipe or launder in the case of a secondary ball mill.

a ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.it works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. a ball mill consists of a hollow cylindrical shell rotating about its axis. t
powerful black powder can be made with mill runs of between 2 and 4 hours. use long drop cords. unplug the cords at the electrical source, not at the ball mill, when you want to stop the mill. run your mill remotely, outdoors, at least 150 feet away from people and inhabited buildings.
