The last formula gives you more accurate COC if you have flow measurement facility available for makeup & Blowdown water in the cooling tower. The cycles of concentration normally vary from 3.0 to 8.0 depending on the design of a cooling tower. It is always advisable to maintain COC as high as possible to reduce make water requirement.

newer milling machines or machines with minimal spindle wear. Rigidity is critical when using carbide tools. Carbide end mills may require a premium price over the cobalt end mills, but they can also be run at speeds 2 1/2 times faster than HSS end mills. The choice of tool material depends on the material to be cut as well as on the maximum

vertical roller mill with separator, cyclone, mill circulation fan, and electrostatic precipitator (EP) and EP fan as shown in Fig.1. Pulverized final products, which is called kiln feed raw meal, are collected at the cyclone and EP. Because of large pressure loss at the cyclone and in order to control mill gas flow, mill circulation fan

When the required machining power value is about the same as the milling machine's rated power, milling productivity approaches its maximum. Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1)

For three phase AC motor torque formula: T = 1.732 x V x I x pf / (2 x pi x N (rpm) / 60) V => Input AC Voltage in volts (line to line voltage) I => Input AC Current in amps. Also while reducing the motor power the torque will be reduced. i.e if you are running y% of …

Step 4 - Lye separation The lye is added at the top of the washing column, and the soap removed from the column as overflow. As the lye is added near the overflow pipe the washed soap is about 20% fresh lye, giving the soap unacceptably high water and caustic levels. Separating off the lye lowers the electrolyte levels to acceptable limits.
