摘要： A mineral lump breaker, for example for use in conjunction with a coal conveyor in a mine, comprises a breaker element and reaction means, for example in the form of a breaker plate or reaction discs. The breaker element and reaction means are carried by a framework straddling the conveyor and are spaced-apart so as to define between them a lump breaking gap. Material on the conveyor is moved into the gap where it is impacted by the breaker element against the reaction means. The reaction means is adjustable with respect to the breaker element periphery to vary the gap dimension.

摘要： An auxiliary device for a longwall mining machine incorporating an underframe, by which it is mounted for movement along the conveyor of the mining machine, and it is coupled to the mining machine. The auxiliary device comprises a rotary breaking or crushing element drivably carried by the underframe and the underframe is provided with a reaction means, preferably a plate, spaced away from an adjacent periphery of the rotary element. In use, material on the moving conveyor passes between the rotating breaking or crushing element and the reaction plate where the material is broken up or crushed. In this way, it can be ensured that any large lumps of coal or rock on the conveyor can be broken down to a sufficiently small size so as not to become jammed beneath the main frame of the mining machine straddling the conveyor.
