石墨选矿机械大致可分为两类,第一类是准备作业所用的机械,第二类是选别作业所用的机械。属于第一类的主要是破碎筛分机械,最常用的有颚式碎矿机、圆锥碎矿机、反击式碎矿机、锤碎机等,颚式、反击式两种主要用于粗、中碎,最后一种主要用于细碎或中碎。圆锥碎矿机无论粗、中、细三级破碎均可使用。目前,国内石墨选厂粗碎均采用颚式碎矿机,此类机械的特点是构造简单、维护检修方使、价格便宜,所以应用很广。锤式碎矿机多用于中碎和细碎,因为该机有格条,所以排矿粒度可控制到一定 Graphite beneficiation machinery can be broadly divided into two categories, the first is the machinery used to prepare operations, the second is the machinery used for sorting operations. Belongs to the first category is mainly crushing and screening machinery, the most commonly used jaw crusher, cone crusher, counterattack crusher, hammer crusher, jaw, counterattack two are mainly used for rough, In the broken, the last one is mainly used for crushing or broken. Cone crusher regardless of coarse, medium and fine crushing can be used. At present, the domestic graphite processing plant are used coarse crushing jaw crusher, such machinery is characterized by simple structure, maintenance and repair party to make, the price is cheap, so the application is very wide. Hammer crusher used in the broken and crushing, because the machine has a grid, so mine particle size can be controlled to a certain
