  • Cement mill - Wikipedia

    The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary ...

  • Coefficient of Performance / Industrial Heat Pumps

    Ammonia, for example, is a very efficient refrigerant with a COPh of 6 for a evaportion temperature of 30 °C and condensation temperature of 70 °C. These same conditions only give a COPh of 4,5 for refrigerant R134A. Other factors that will effect the efficiency of a heat pump are system controls, efficiency of pheripheral equipement like fans, pumps, etc.

    The slope of this line is often called the laser efficiency and in this case is equal to 63%. By using the pump power at the lasing threshold calculated previously (see the section “Power of the pump at the lasing threshold”), the output power can be calculated as 266 mW (if the maximum pump power is equal to 500 mW). This value is fairly close to what is found experimentally. Figure E13 ...

  • Impact of Temperature on Intel CPU Performance

    I am sure the same would apply to CPU tech. I think temperature affects longevity but has a very small if any affect on performance unless thermal tolerances are exceeded. Unless we are talking about absolute zero, super conductors and super computers - (in my experiences) running your gear at 20c vs 80c is not going to affect performance.

  • Understand heating options for your home

    We recommend you to set your temperature between 18°C to 20°C. Every 1°C higher will add around 10% to your heating bill. The most efficient way to use your system is by zoning it. This allows you to split the house into different zones, so that you can limit it to only heat the areas you’re using.
