Definitions

  • the present invention relates to a mineral breaker.
  • the present invention relates to a mineral breaker including a pair of rotatable drums each of which are provided with opposed breaker teeth.
  • the teeth on each drum are arranged in circumferentially extending groups and the groups on the drums are staggered so that teeth in one group on one drum pass between neighbouring groups of teeth on the other drum.
  • the present invention provides such a mineral breaker which further includes a breaker bar assembly having a plurality of breaker teeth extending longitudinally of the drums and located between and beneath the axes of rotation of the drums so as to co-­operate with the breaker teeth on the opposed drums for breaking oversized lumps of mineral.
  • the plurality of breaker teeth are arranged on an elongate support member which is mounted at opposite ends to opposed end walls of the breaker housing.
  • the elongate support member is cast from a suitable ductile steel.
  • the teeth are preferably each in the form of a base formed integrally with the support member and to which a removal tooth cap is attached.
  • Each tooth cap is preferably formed of a hard wearing steel such as a high manganese steel.
  • the mineral breaker l0 shown in Figures l to 3 includes a housing l2 in which is rotatably housed a pair of breaker drums l4.
  • Each drum includes breaker teeth l6 which are arranged in circumferentially extending groups l8.
  • the groups l8 on one drum are staggered in relation to the groups l8 on the other drum such that the teeth on one drum sweep in between teeth of adjacent groups on the other drum.
  • Each drum l4 and teeth l6 may be of any desired construction; preferably the teeth l6 are constructed in accordance with the construction disclosed in our United Kingdom Patent Application No. 85l95l6.
  • Each end wall 20 of the housing is preferably constructed from three side wall end portions 20 a , 20 b and 20 c which are bolted together.
  • Each portion 20 a , 20 b and 20 c are preferably a steel casting.
  • Portions 20 a and 20 b are provided with recesses so as to define therebetween bearing housings 24 (only two of which is visible) in which bearings 26 are located.
  • the bearings 26 rotatably support the drum shafts 27 (only one of which is visible).
  • a breaker bar assembly 30 extends between and is supported by opposed end portions 20 c .
  • the assembly 30 includes a main elongate support body 3l having support flanges 32 integrally formed at each end.
  • the support flanges 32 overlap a flange 20 d formed on portion 20 c and are thus supported thereby.
  • Shims 38 are located between support flanges 32 and flanges 20 d in order to provide height adjustment of the breaker bar assembly 30 relative to the breaker drums l4.
  • the support flanges 32 are held in position by bolts 34.
  • a series of tooth bases 40 project from each longitudinal side of the main support body 3l.
  • the tooth bases 40 of each series are spaced from one another to define gaps 4l through which breaker teeth l6 on a facing breaker drum may sweep through on rotation of the drum.
  • each tooth cap 50 has a recess or pocket 5l which seats upon an elongate projection 53.
  • the dimensions of the pocket 5l and corresponding projection 53 are such as to provide a tight fit to effectively key the tooth cap in position so as to accommodate working loadings.
  • Each tooth cap 50 is held in place on a projection 53 by means of bolts 55.
  • the external profile of the tooth caps 50 is chosen to cater for the type of mineral to be broken and so the shape may vary accordingly. However it is preferred to provide a raised central portion 56 which as seen in Figure 3 is located centrally between the drums l4. The central portions 56 of all the tooth caps are aligned longitudinally of the support 3l preferably contiguous to collectively form a ridge or shed.
  • the provision of the breaker bar assembly 30 enables the mineral breaker to size mineral from a relatively large size to a relatively small size in one pass.
  • mineral lumps of say up to one metre cube size into the machine and obtain mineral lumps not exceeding say 200 mm cube size.
  • This is very advantageous as it means that one machine can be used at a mineral winning location to break down won mineral to a size suitable for conveying the mineral away.
  • Size variation of the obtained product may be achieved by adjusting the height of the breaker bar assembly relative to the breaker drums.
  • a breaker bar enables the breaker drums l4 to be independently driven which is advantageous as it enables optimum grip to be obtained on large lumps of mineral being gripped between the opposed leading faces of breaker teeth on opposite drums. It is however possible if desired, to drivingly connect both breaker drums and drive them with a single power source.
