Abstract
A breaker block, radial and rotational breaker block adjustment assembly and vertical adjustment means for rock crushers having an impeller mounted on a vertical axis. The breaker blocks are mounted in cell members forming a concentric circle about the vertical axis. The breaker blocks are detachably connected to adjustment assemblies which move the blocks toward the impeller as they wear and permit rotation if the impact face wears unevenly. An annular ring in one form of the invention supports the breaker blocks and cell members and is movable vertically in relation to the impeller.
Claims6
In a rock crusher having a housing (17) and an impeller (4) mounted on a vertical axis (5) the improvement comprising:
- a. a plurality of breaker blocks (1) surrounding said impeller and each breaker block having a longitudinal axis (12), an impact portion (6) with a distal end (7) forming an impact face (8), a proximal portion (9) and side walls (23);
- said impact portion has a transverse across section which is symmetrical to said longitudinal axis and which forms an equal sided polygon and which has a constant cross sectional area throughout its length and attachment means (11) formed in said proximal portion;
- b. a plurality of cell members (16) connected to said housing forming a chamber (18) open at its distal end (19) to the interior of said crusher and the proximal end (21) is open to the exterior of said housing;
- c. each of said cell members having walls (22) slidably registering with said side walls (23) of said breaker blocks;
- and
- d. an adjustment means releasably connected to said attachment means (11) in said proximal portion.
