Pulp and paper mills consume vast amounts of fresh water. A 1,000 tonne per day bleached kraft pulp mill may use more than 150 million litres of water a day; a paper mill even more. In order to prevent adverse effects on mill equipment and to maintain product quality, the incoming water must be treated to remove contaminants, bacteria and minerals.

Effect of Temperature on Power

21-10-2011The reason why the power-consumption is increasing with temperature has to do entirely with the static leakage power consumption of the CPU (it is independent of clockspeed, solely dependent on temperature and voltage) and a phenomenon known in physics as the Poole-Frenkel effect.

Power Factor

Loads such as motors or lamp ballasts will cause the load current to lag behind the voltage and capacitor loads will cause the current to lead the voltage. Apparent Power – common unit is the kilo-volt-amp (kVA). The apparent power is the "vector sum "of the Real Power and the Reactive Power.

Effect of the mill on the mill_cement production process_lvssn

The effect of the grinding body on the material in the second silo is mainly grinding, and the crushing effect is very small. Under the driving of the mill cylinder, the motion state of the small grinding body is rubbing, rolling and sliding. The grinding body grinds and peels the material particles in the process of laxation and rubbing.

Ball Mills

Such mills are usually called pebble mills, but the working principle is the same as for ball mills. As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is correspondingly smaller than for a ball mill.
