ABSTRACT:
Apparatus and process for breaking blocks of compressed particulate material (e.g., coconut coir, peat moss and the like) includes feeding blocks of compressed coconut coir into a confined breaking space, and breaking coconut coir from the blocks to form a loose mass of coconut coir by causing the blocks of compressed coconut coir to tumble against one another along a general figure-eight flow path. Most preferably, the blocks of compressed particulate material fed into the confined breaking space are brought into contact with a spirally oriented rotary breaking bar. The breaking bar is supported concentrically relative to a central axis by means of radially disposed support arms which carry generally triangular lift teeth. The action of the spiral breaking bar and lift teeth (if present) cause the blocks of compressed particulate material to tumble against one another in the confined chamber along a general figure-eight flow path. This continual collision of the blocks against one another during the figure-eight tumbling action thereby causes the particulate material to be broken from the blocks. The loose mass of particulate material which is broken from the blocks falls by gravity through a screen at the bottom of the confined breaking chamber where it may be collected and discharged.
