发明名称 MEJORAS EN METODO Y APARATO PARA MOLER CRIOGENICAMENTE MATERIAL DE HULE
摘要 <p>The production rate of a conventional cryogenic grinding system incorporating an impact mill may be increased by (a) providing means to allow at least 70% of the embrittled material entering the mill to leave the mill before it passes the inlet; and (b) providing means to restrict the flow of the cold gas through the impact mill. The product leaving the impact mill is screened and any oversize is preferably recycled to the impact mill.</p>
