Ball Mill Grinding Capacity Calculator Ball Mill Motor/Power Sizing Calculation Ball Mill Design/Sizing Calculator The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to (HPhr/short ton = 1.34 kWh/short ton) Wi
Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
Most of the cement ball mills are used in the circulating grinding system, which is characterized by high grinding efficiency, large mill output, and low power consumption. Especially when grinding slag cement, the performance is more outstanding, compared with the general mill.
The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0
To illustrate how grinding conditions can affect ball mill efficiency, the batch grinding model will be used to model closedcircuit ball milling of the sodalime glass. For this model, the size range of a particulate assembly in a batch mill is divided into size intervals with a maximum size X 1 above and a minimum size X n+1.
Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ballmill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 030% pebbles, by volume, with savings in energy and ball consumption increasing progressively.
Ball mill, as a necessary grinding equipment in mineral processing production line, accounts for as much as 30% of the overall operating cost of the separation plant. 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
New and Used Ball Mills for Sale Savona Equipment is a new and used Ball Mill supplier worldwide.A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.
2 Grinding ball mill adopts groovetype circular lining plate to increase contacting areas of iron balls and ores, which enhances grinding action and ore lifting capacity and decreases energy consumption. 3 Adopts whole milling house to makes it easy for construction and installation. 4.
Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
When the feed rate of the ball mill is increased or the grinding rate is required to be too fine, the service efficiency of the ball mill wearresistant grinding media ball is in a lower range, thus increasing the power consumption of the ball mill and increasing the damage rate of the wearresistant grinding media Ball.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4 or 5in. balls are more commonly used for ballmill grinding.
