Abstract: Apparatus for transporting mineral from a point of mining to a remote location, the apparatus including a mobile mineral breaker rig (MBR) having a mineral outlet, the rig including a fluid inlet pipe for receiving conveying fluid, a mineral inlet for introducing mineral from said mineral outlet into said fluid pipe and a fluid outlet pipe for conveying said fluid mixed with mineral received from said mineral outlet, an extensible pipeline assembly (EPA) connected at one end to said inlet and outlet pipes and being adapted for connection at its opposite end to one end of a static pipeline communicating with said remote location, said extensible pipeline assembly being expandable to enable said mobile rig to move away from said one end of the static pipeline whilst maintaining fluid communication therewith, said extensible pipeline assembly comprising a series of elongate pipe assemblies (90a, 90b, 90c) which are articulated at adjacent ends to one another in a zig-zag manner via an articulated joint, each elo

Abstract: A mineral breaker including at least one breaker drum having breaker teeth projecting radially therefrom, the teeth being arranged so as to define a series of discrete circumferentially spaced helical formations extending along the drum.
