What it is the optimun speed for a ball mill ? - posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts. In the other side of my shafts there are two 40 mm ...
it is a monochamber mill designed to grind the roller press product. if we calculate the shaft power with 28% filling it comes to more than 2600 kw with 210 t grinding media. also 28% filling do not corresponds to 180 t media, it is more than 210 t. supplier has given a ball mill motor installed kw of 2600 only. please comment. thanks ...
•The gearbox between motor & ball mill had been recently rebuilt. •Two identical ball mills were in place at the plant (1A & 1B). •These machines are used to pulverize or crush lime into small particles (dust) that is then made into a slurry and injected into the flue gases to reduce pollution.

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; 𝐶𝐶3 = 2.44 𝐷𝐷 0.2 (3) However, it is important to note that C3 =0.914 vessel used in producing the ball mill was got from a
gear transmission. The gearless ball mill has emerged. Because of its massive volume, the gearless ball mill is difficultto manufacture and maintain.
