The Optimization of Process Parameters of Large-Scale SAG Mill. Article Preview. Abstract: This paper is based on the kinetic theory of ore and steel balls in the SAG Mill and theoretical research of power consumption. Orthogonal method is taken to design experimental plan while effective power of the SAG Mill, collision times between steel
Learn MoreThe end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation

Learn MoreMar 21, 2007 · Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are …
Learn MoreAug 30, 2019 · 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.lidkoping wet ball mill machines. 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
Learn MoreJan 01, 2011 · The process involves feeding large rock particles and water into a grinding mill of several meters of diameter containing steel balls which rotates at a fraction of its critical speed. The slurry and ball charge adheres to the walls of the mill before cascading off at a given angle, causing impact and thus fragmenting the ore
