Fig 2 Laboratory ball mill and cylpebs used in the tests 222 The milling conditions The influences of operating parameters such as mill speed of Nc ball filling ratio J powder filling ratio fc ball size distribution grinding aid dosage gMg and grinding time min were investigated in this study
0are the reference breakage parameters corresponding to the ball diameter d 0 aand are the predicted breakage parameters for ball diameter d The combination of Equation 27 28 210 and 211 allows one to describe or predict the effect of ball size on the selection function
Ball mill application Ball mill grinding is a highly energy consuming process and the ECSProcessExpert Ball mill application is built to meet the increasing demand for maximum production with minimum power consumption while minimizing variations in quality Benefits 3Up to 6 increase in production Up to 4 reduction in ball mill specific
density ball mill speed and grinding media consumption rate water spray rate on the highfrequency screen and feed pulp density to the screen The performance of the ball mill varied with the ore properties The effect of process parameters on ultrafines generation and power consumption in the ball mill is explained further
In ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables
A Slice Mill of 72 diameter by 12 wide would replicate the result of a normal production mill 72 in diameter as 120 long A Slice Mill is the same diameter as the production mill but shorter in length Click to request a ball mill quote online or call 6303503012 to speak with an expert at Paul O Abbe to help you determine
