Articleosti887498 title optimization of comminution circuit throughput and product size distribution by simulation and control author kawatra s k and eisele t c and weldum t and larsen d and mariani r and pletka j abstractnote the goal of this project was to improve energy efficiency of industrial crushing and grinding operations
A truncated feed mimicking secondary crushing of the sag feed was detrimental to the operation resulting in reduction in both circuit throughput and efficiency finer ball charge size distribution was beneficial for single stage sag mill operation being responsible for 43 reduction in the circulating load in milling with only a
All circulator pumps are typically sized based on the heat load and head loss pressure drop for a given zone knowing the heat load in btus for a given zone allows to calculate the required circulator pumps flow rate in gallons per minute gpm for hot water hydronic or radiant heating applications the following equation can be
Aug 18 2014 admittedly it’s quite a few calculations to get to the definitive pump size and sizing programs are available to do most of the work still it’s important to understand the logic that goes into a properly designed hot water recirculation system especially as system designs become more complex as we shall see in some up coming
