    • A mineral breaker (10) including a pair of rotatable drums (14) each having radially projecting breaker teeth (16), the teeth on both drums being arranged in axially spaced groups (18) of circumferentially spaced teeth, the groups of teeth on one drum being axially offset from the groups of teeth on the other drum so that teeth in one group on one drum pass between neighbouring groups of teeth on the other drum, and a breaker bar (30) assembly located beneath the pair of drums and arranged to co-operate with the teeth on the drums so as to break oversized lumps of mineral passing between the drums, the breaker bar assembly including an elongate support member which extends longitudinally of the drums and on which a first and second series of laterally projecting breaker teeth are supported, the breaker teeth in each of said series of teeth being spaced from one another longitudinally of the support member to enable the groups of breaker teeth on a respective one of the drums to sweep therebetween.

    • A sizer tooth assembly for a mineral sizer is described. The tooth assembly includes a horn protrusion extending from a rotatable support, the horn protrusion having a pair of opposed front and rear faces; and a shell structure encapsulating the horn protrusion and defining the outer shape of the sizer tooth; wherein the shell structure comprises exactly two cover formations which are non-releasably secured to one another but not to the horn protrusion, to define when so secured a unitary tooth assembly. Each of the two cover formations seats upon and presents an inward engagement face to a respective one of the pair of opposed front and rear faces of the horn protrusion; and each such engagement face of a cover formation and its corresponding face of the horn protrusion are provided with a complementary arrangement of projections and recesses configured such that when the two cover formations are non-releasably secured to one another the shell structure is releasably connected upon the horn protrusion. A mineral sizer including such tooth assemblies and a method of constructing such a tooth assembly and especially of constructing a replacement for repair are also described.
