ball mill designpower calculation motor with around 1400 horse power is calculated needed for the designed task now we much select a ball mill that will draw this power the ball mill motor power requirement calculated above as 1400 hp is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution the following shows how the size or 2.2.1 high-efficiency fans and variable speed drives for mill vents 2.3 clinker production 2.5.2 replacing a ball mill with a vertical roller mill, high-pressure grinding rolls, 2.5.7 high-efficiency fans for cement mill vents. get pricethe feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.jan 01, 2020 the new laboratory ball mill with classifier set-up, shown in fig. was specially fabricated for conducting experiments in the laboratory.it has a length of a diameter of 1.5 and is fitted with a newly designed discharge end with six shell lifters, as shown in fig. and and fig. and the feed end of the rotating drum has an opening of 0.3 to feed the sample.
oct 23, 2015 introduction. cement is an energy-intensive industry in which the grinding circuits use more than of the total electrical energy consumed and account for most of the manufacturing cost .the requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO from the kilns. In recent years, the production of composite cements has ball mill 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 either wet or dryjan 01, 1983 In terms of mill diameter in feet, power in kw, ball mass mballs in sort tons, fraction of critical speed and fraction of mill loaded with balls the equation is: --p- 3.10 -1.13 mbs ball size-correction factor was included by bond to account for media slippage in large mills and is not of ball mill, and maintains the motor with steady operation state when the equipment is running at variable frequency, ensuring the motor has constant power characteristics. the ball mill frequency control and speed regulation system makes ball mill running reliably at low speed, ensuring the normal process control requirements.
