Enhanced retractable flow discharge extension

A coal pulverizer system comprising:

• a pulverizing structure having a grinding ring above which are grinding rollers;
• a feedpipe to deliver from above raw coal to the pulverizing structure;
• a classifier cone positioned around the feedpipe to collect oversized coal for the pulverizing structure;
• an enhanced retractable flow discharge extension contiguous with the classifier cone and configured to deliver the collected oversized coal back to the pulverizing structure, the enhanced retractable flow discharge extension having a conical extension portion and a telescoping portion, wherein:
• in an extended configuration, a distal end of the telescoping portion is a first distance from the grinding ring;
• and in a retracted configuration, the distal end of the telescoping portion is a second distance from the grinding ring, the second distance being greater than the first distance;
• and
• at least one removable chain fall means attached to the
• conical extension portion and attached to the telescoping portion to move the telescoping portion thereof between the extended configuration and the retracted configuration;
• and
• wherein the telescoping portion comprises:
• a fixed cylindrical portion having an upper end contiguous with an outlet end of the conical extension portion;
• a movable cylindrical portion having a circumference larger than a circumference of the fixed cylindrical portion, the movable cylindrical portion being movably attached to the fixed cylindrical portion;
• and
• a distal portion movably attached to the movable cylindrical portion, the distal portion having a straight portion and a tapered portion contiguous with the straight portion.
