How to calculate electrical connected load.

you have a)30 Nos of 1 KW of resistance load= 30KW b) Inductive load 3x3.7=11.1KW Total load is=41.1KW if there is lighting load and capacitive, add all the load in that building, that is your connected load. if these load are put at a time then it is called as demand factor the sum of individual load /connected load is called diversity factor.

Grinding in Ball Mills: Modeling and Process Control

2012-7-10 · The design of a ball mill can vary significantly depending on the size, the the mill shaft power and the specific gravity of the material.

A power model for fine grinding HIGmills with

In both cases the model predictions are reasonable, although for the operating mill the power is underpredicted by about 20% (i.e. the slope of the line is 0.8). Although this is a little low in purely quantitative terms, it is at least conservative in terms of sizing a new full-scale operating mill.
