Abstract: A tooth formation for use in a mineral processing machine is described. The tooth formation has: a pick formation comprising an elongate body comprising a shaft having at one axial end a mineral breaking pick head extending radially beyond the elongate body to define a rearwardly facing first seating surface; and a support formation defining a receiving aperture of complementary shape and size to said shaft of said elongate body so as to receive the same, and a forwardly facing second seating surface configured to abut the first seating surface of the pick formation with the shaft so received. The first and second seating surfaces comprise arrangements of one or more complementary projections and recesses radially symmetrically disposed about an axial direction of the elongate body. A mineral processing machine including at least one and preferably a plurality of tooth assemblies or tooth cap assemblies according to any preceding claim.

Abstract: A feeder (5) comprising: a feed device having: a material receiving end for receiving material; a material discharge end (11) distal of the material receiving end; an endless conveyor disposed to define a conveying surface (9) between the material receiving end and the discharge end (11) movable in use to cause material received at the material receiving end to be conveyed to the material discharge end (11), wherein the endless conveyor comprises a plurality of successively arrayed metal plates, pans or flights; a material flow monitoring device disposed in association with the feed device and adapted to obtain in use a measurement representative of a quantity of material passing along the conveying surface (9) of the endless conveyor; wherein the material flow monitoring device is adapted to obtain a measurement representative of a weight of material passing along the conveyor.

Abstract: The disclosure relates to a feeder apparatus, system and method applied to the movement of bulk material and in particular for the movement of bulk run of mine material from a working site.
