Calculations of media charge. To calculate media charge for batch mill. M = 0.000929 x D2 x L where : M = Grinding media charge in kgs. D = Internal Dia of the Mill in cms. after lining. L = Internal length of the mill in cms. after lining. To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L
calculation of cement ball mill capacityAug 11, 2016 This cement ball mill is mainly applied in grinding cement completed products and raw materials and also motor rating calculation in cement CEMENT GRINDING OPTIM.
The biggest ball size is calculated by the Bond formula and depends mainly from feed size and mill dynamics. (See also “BP Selecting Shell Liners in ball mills” to avoid 100mm balls). Most common is the 90 mm ball as biggest size but even 80 mm is possible depending.
30%-. -. ~ 15%. For commercial cement plant ball mill 12 m long, 3.8 m diameter, calculations performed using design equations showed top side steel ball size M = 127 mm; mill speed actual n = 16.6 rpm; grindability G = 1.69 g/rev, for throughput 80 T/hr clinker grinding from ~ 40 mm size down to average 5–6 microns,.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials.
izontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement quality is critical and two- fold. It affects two of the main . formulae for the calculation of the clinker com- . The control of cement grinding/mixing process in an industrial mill regarding SO3 content has.
1. critical speed, speed ratio. When the mill in linear velocity with balls up to A point, due to the equal to the force N and the centrifugal force of the C steel ball weight G method, namely a ball thrown down. If the mill speed increase, ball started behind the fall point will improve. To the mill speed increases to a certain value C,.

on standard modules. 2. The FL ball mill is designed for grinding of clinker, gypsum and dry or moist additives to any type of cement. The mill may operate in either open or closed circuit and with or without a pre- grinder to achieve maximum overall grinding efficiency and high flexibility in terms of product quality.
An interesting case is the Saxon and Norman plants: the 1901 Saxon plant was installed with Schneider Kilns and ball-and-tube mills, while the "more modern" Norman (1904) had rotary kilns and Griffin mills. However, the Griffin mills were abandoned from 1912 and the Norman clinker was taken to Saxon for grinding.
You can ask your vendor who made this machine. It's difficulty to calculate capacity of a machine or maximum capacity. It's depend on a lot of parameters. But you can calculate specific energy(unit kW/kg e.g. 0.05kW/Kg) to know which mill better. .
