  • Raw Coal Spillage Or “Pyriting”

    Coal dribble or spillage is raw coal that is rejected through the pulverizer’s pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be Coal Pulverizers an overview ScienceDirect Topics,In the first computational example the coal pulverizer drive system is considered. This machine is driven by the 22 kW asynchronous motor by means of the reduction planetary gear of the resultant ratio 1:5.33.The static characteristic of this motor as well as the drive system first torsional eigenform of frequency 4.2 Hz are shown in Figs. 2a and 2b, respectively.

  • how does pyrite affect the utilisation and processing

    Pyrite Wikipedia. Pyrites metallic luster and pale brassyellow hue give it a superficial resemblance to gold, hence the wellknown nickname of fools goldThe color has also led to the nicknames brass, brazzle, and brazil, primarily used to refer to pyrite found in coal the name pyrite is derived from the greek pyrits lithos, quotstone or mineral which strikes firequot, in turn fromProcess for electrostatic separation of pyrite from ,Abstract. An improved process is disclosed for electrostatic separation of pyrite from powdered crude coal comprising vigorously mixing the powdered crude coal with a selected fatty acid glyceride as a conditioning substance and conducting the electrostatic separation at a relative humidity of 2.5--20 percent and a temperature between room temperature and 100/sup 0/C.
