反擊型固定錘頭錘式破碎機主要由殼體、轉子、反擊板、篩箅、電動機等零部件組成（見圖2）。gaiposuijishizaiputongchuishiposuijidejichushang，xiqufanjishiposuijiyoudian，zaizhuanzizhuandongfangxiangdeceshangfangshezhifanjibanxingchengjiaodadefanjiqiang，youjinliaokouxialuodeliaokuaibeichuitouzixiaershangyingji，shoudaochongjidewuliaobeigaosupaochuzhuangjifanjiban．fanjibanyoujiangliaokuaifanshehuilaijieshouchuitoudezaicidaji，zaiciqijianliaokuaizhijianhaihuixianghuzhuangji，liaokuaijingduocidajiposuibianxiaoluoxia，zaijieshouchuitouhechenbanjishaibizhijiandejiyayanmo．suiliebianxiaodewuliaocongxiafangshaibikongxipaichu。youyuzaiposuiguochengzhongchuleshiyongchuitouposuiwuliaozhiwaihailiyongfanjibanduocifanjiposuiwuliao，suoyiyuputongchuishiposuijixiangbikeyiyongjiaoxiaodenenghaodedaogenghaodeposuixiaoguo。
