ball powder ratio ball milling best way to determine the ball-to-powder ratio in ball , as for as ball to powder ratio is concerned, if the purpose is mixing you should go for 5-10 ration of ball with powder in case if you want to reduce the size or ally the powder then select high . ball and material ratio of ball mill ratio
planetary ball mill. the mechanics of this mill are characterized by the rotational speed of the plate p, that of the container relative to the plate v, the mass of the charge, the size of the ball, the ball to powder ratio and the radius of the container. a schematic of the planetary ball mill is shown in fig.2.4
ball mill grinding - ramkrishna the load of the ball is usually a little more than half of the volume of the mill. generally 23 volume of the mill filled by material and ball. if the fill level is low, most of the energy of the balls is wasted in impacts between them leading to low comminution ratio. if mill
ball mill shape factors in the period prior to 1927 averaged 1.11 for 29 center discharge mills and 1.01 for 30 peripheral discharge mills. with the resumption of new plant construction after the 1930s depression, the morenci concentrator continued the 11 ratio with its 3.1 x 3.1 m 10 x 10 ft mills. the ratio was increased progressively from then on, reaching 1.6 and 1.81 for the
rock to grinding media ratio. the ball mill is a key piece of equipment for grinding crushed materials and it is widely in production lines for powders such as cement silicates refractory material fertilizer glass ceramics etc as well as for ore dressing
what is the circulating load ratio in your ball each pass through the ball mill then the circulating load ratio is equal any screen size you choose ball mill circulating load from screen anlysis. lecture 11 material balance in mineral processing
reduction ratio in conical ball mill rollershopdinklage. calculation of the ball mill reduction ratio henan for overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be to determine the percent charge by volume as a function of the vertical height above
the ld ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15, 20 and 25. the experiments clearly indicated that the optimal ld ratio and the optimal ball charge filling ratio are different for each feed fineness
ppt of ball mill performance wembley primary school. ball mill operating principles components uses nbsp 0183 32 a ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 of the mill
r- the radius of the ball. the volume of a grinding ball is determined by the formula v43r 3, where v- the volume of the ball. pi constant, a mathematical constant that is equal to the ratio of the circles circumference to its diameter. 3.14 is a commonly value for pi r- the radius of the ball
the mill speed was maintained at 101rpm, the ball size at 25mm and the ball mass to sample mass ratio was kept constant at 101. the mill was run for 2min., 4min., 6min., 8min., and 10min. each. each product was sieved for 15min. and the cumulative per cent mass passing 355m and 50m were determined
2.ball mill pulverizing ratio. general mill crushing ratio of up to 300 or more, the device is easy to adjust and control the fineness of the material, uniform particle size, good mixing. 3.can be adapted to different operating conditions, the job can be either dry-wet operation, but also the
