Abstract

The invention discloses a grinding roller removal mechanism for a pulverizing mill. The grinding roller removal mechanism for the pulverizing mill comprises grinding rollers and grinding roller shafts, wherein the grinding roller shafts are cantilever shafts; the outer end of each shaft is hinged to a grinding roller bracket; a piston rod of an oil cylinder which is arranged on a rack is hinged to each cantilever shaft; a protruded limiting shaft is arranged on each bracket and is opposite to each cantilever shaft beneath the limiting shaft; a pin shaft is arranged at the position, on the right side of the axis of a hydraulic cylinder, on the rack; a swinging plate at the upper part of each grinding roller bracket is hinged to the corresponding pin shaft at the upper part of the rack. The grinding roller removal mechanism for the pulverizing mill has the remarkable advantages that the grinding rollers can be quickly and conveniently removed; the pressure of the grinding rollers can be conveniently adjusted; the pulverizing mill is not damaged.

Description

technical field [0001] The invention relates to a grinding equipment, in particular to a grinding roll removal mechanism of a grinding machine. Background technique [0002] The existing fly ash processing equipment mainly includes vertical pulverizers and tube mills. The vertical pulverizers are widely used due to their high efficiency. The grinding roller needs to be removed from the mill chamber of the pulverizer for replacement. The current method is to remove the grinding roller and then remove it for replacement. The workload of disassembly is large and the time is long, which affects production. Contents of the invention [0003] The object of the present invention is to provide a grinding roller removing mechanism of a pulverizer which is fast and convenient for overhauling the grinding roller. [0004] Another object of the present invention is to provide a grinding roll removal mechanism of a pulverizer that can adjust the pressure on the grinding roll without ...
