煤炭作为一种不可再生的国家型战略资源，始终担负着我国能源安全的兜底保障作用。但随着原煤入选率的持续提升，作为煤炭洗选副产品的煤泥产量也相应增加。针对煤泥滤饼含水量大、黏性强、杂质多等特性，对破碎机结构提出了更高要求。根据煤泥滤饼破碎作业高效率高产能要求，介绍了煤泥滤饼破碎技术与装备的不同发展阶段，重点介绍了锤式破碎机、辊式破碎机、多级复合式破碎机的发展现状，并从工作原理、结构方案、破碎效率等方面全面剖析了不同形式煤泥滤饼破碎机的关键技术。最后，展望了煤泥滤饼破碎机的发展趋势。

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 requirement 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, together with an comprehensive analysis of the key technologies of these breakers from the perspectives of working principle, structural design and working efficiency. Lastly, the co-authors look ahead to the developing trend of cake breakers in the future.
