Abstract
A mineral breaker having at least one breaker drum, the drum including a generally cylindrical support body from which a plurality of radially extending projections project by a distance equal to at least half the radius of the body, each projection being covered by a tooth sheath to define a breaker tooth having a maximum radial dimension projecting beyond the circumference of the support body which is greater than a major portion of the radius of the support body.
Claims8
In a mineral breaker including a breaker drum having an axis and a plurality of breaker teeth projecting radially from the drum and arranged in circumferentially extending groups of teeth spaced along the axis of the drum, each of said breaker teeth having a leading face, and further including a plurality of opposed breaker teeth positioned so that on rotation of the drum mineral lumps to be broken are gripped between the leading face of the teeth on the drum and a pair of said opposed teeth to thereby break the mineral lump gripped therebetween by a snapping action, the improvement of each of the breaker teeth in each circumferentially extending group comprising a radially extending projection enveloped by a tooth sheath, each projection having a forwardly facing recess into which a trailing end of its immediately preceding tooth sheath is received for restraining radial outward movement of said trailing end, each sheath having a leading wall provided with an opening through which said trailing end of its preceding tooth sheath passes to enter said recess.
