excess air in raw mill. hello, we use a ball mill for raw material grinding with central discharge, the problem arises with the difference in volume flow of air at NTP between the inlet and the outlet, for eg at the inlet we have a volume flow of 33000Nm3/hr, the out let volume flow comes around to almost double this value around 70000Nm3/h. what is the reason for this sudden difference

Avoid pockets or high point where air can accumulate in the discharge piping. An ideal pipe run is one where the piping gradually slopes up from the pump to the outlet. This will ensure that any air in the discharge side of the pump can be evacuated to the outlet. 12. Water hammer. Be aware of potential water hammer problems.

The inlet and outlet diameters are the critical design variables, the cyclone diameter merely being the size of the housing required to accommodate these apertures (Lynch et al., 1974, 1975; Rao et al., 1976). This is true where the inlet and outlet diameters are essentially proxies for cyclone diameter for geometrically similar cyclones.

Step 1: Determine Inlet Water Properties. Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality): Pressure = psig. Quality = [Steam Property Calculator] => Specific Enthalpy = btu/lbm.

15% moisture to 3%. The required evaporation rate is 12% of 1 te/h, or 120 kg/h. If we use air at 1500C with an inlet humidity of 10 g/kg, the chart (Figure 1) shows the wetbulb temperature is about 420C. Assuming an outlet temperature of 600C, we find that the dewpoint is 400C and exhaust humidity 46 g/kg. The humidity change over the
