Abstract
A conical gyratory grinder-crusher having a rigidly supported outer frustroconically shaped grinding-crushing member and an inner conical grinding member supported on a wobble mechanism which is in turn adjustably supported by air bellows so as to adjust the spacing between the inner and outer grinding-crushing members defining the grinding-crushing cavity, and therefore the particle size of the ground material. The bottom of the grinding-crushing cavity is closed by a flexible member. The flexible member seals the bottom of the grinding-crushing cavity. A slurry of fines or ground material is discharged from the grinder-crusher through grate discharge outlets provided in the lower portion of the inner conical grinding-crushing member.
