矿石粉碎机
摘要：
矿石粉碎机(10)包括一列并排的具有径向突出的粉碎齿(38)的粉碎鼓组件(30)。该列包括至少四个粉碎鼓组件(30)，布置成限定位于一对外粉碎鼓组件之间的一对相邻的内粉碎鼓组件(30a)。该一对内粉碎鼓组件(30a)在它们之间限定矿石沉积区(DM)用于接收来料矿石。所述一对内粉碎鼓组件(DB)的粉碎鼓组件(30a)以相反的方向转动，这样在使用中，每个所述内粉碎鼓组件(30a)上的粉碎齿(38)都会作用于沉积在所述矿石沉积区(DM)的矿石，导致搅动沉积的来料矿石，使小块矿石通过它们之间，同时防止大块矿石通过它们之间。所述一对内粉碎鼓组件(DB)的每个粉碎鼓组件(30a)作用于来料中的大块矿石，导致将大块矿石向外朝向各个所述外粉碎鼓组件移动。
摘要（英）：

A mineral breaker (10) including a row of side-by-side breaker drum assemblies (30) having racially projecting breaker teeth (38). The row includes at least four breaker drum assemblies (30) arranged to define an inner pair (DB) of adjacent breaker drum assemblies (30a) located in-between a pair of outer breaker drum assemblies. The inner pair of breaker drum assemblies (30a) defines therebetween a mineral deposit region (DM) for receiving mineral in-flow. The breaker drum assemblies (30a) of said inner pair (DB) of breaker drum assemblies being rotated in opposite directions such that, in use, breaker teeth (38) on each of said inner breaker drum assemblies (30a) act upon mineral being deposited in said deposit region (DM) to cause agitation of the deposited mineral in-flow in order to encourage undersized mineral to pass therebetween whilst preventing oversized mineral passing therebetween. Each breaker drum assembly (30a) of said inner pair (DB) of breaker drum assemblies acting upon oversized mineral in the material in-flow to cause the oversized mineral to be moved outwardly towards a respective one of said outer breaker drum assemblies.
