In view of Jingdezhen power plant coal-fired coal quality seriously deviated from the design parameters

resulting in the grinder power decline

high single consumption

poor reliability

affecting the safety and economic operation of the unit.Starting from the principle and present situation of ZGM medium-speed roller disc grinder

the practice and test analysis of various transformation schemes were carried out

and two schemes of load enhancement and Venturi dynamic ring transformation were compared

and the maximum yield of the grinding machine could be increased by 18% after comprehensive implementation coal machine current

powder consumption than before the transformation of the drop of 10%

especially in the coal volume 50 to 60 t/h is more obvious

in addition to the effect of excellent efficiency reduction

but also fully consider the cost-effective and long-term reliability of the transformation

to achieve maximum comprehensive benefits

is the same type of grinding machine transformation of good practice.
