Abstract：As a nonrenewable national strategic resource,coal has always played the role of acting as a back-up in assuring China's energy security.However,along with the incessant increase of raw coal treatment rate,the output of coal slime as a by-product of coal washing process is seen to rise correspondingly.As the cake product of filter press features high contents of both moisture and impurities as well as a high viscosity,a higher require-ment is thereby placed on the structure of filter cake breaker for enabling it to operate with a higher efficiency and capacity.An introduction is made to the developments of the technologies and breakers in different stages with the emphasis placed on the state-of-the-art of hammer,roll and multi-stage compound-type breakers,to-gether with an comprehensive analysis of the key technologies of these breakers from the perspectives of work-ing principle,structural design and working efficiency.Lastly,the co-authors look ahead to the developing trend of cake breakers in the future.
