Crusher block assembly for particulate size reduction system

1. A crusher block assembly for a particulate size reduction system comprising:

a) a crusher block having

i) an inboard face configured and adapted to cooperate with a swing hammer in a crusher chamber of a particulate size reduction system to crush particulate; and

ii) an outboard face for receiving an adjustment mechanism;

b) an adjustment mechanism operatively joined to the outboard face of the crusher block, the adjustment mechanism being configured and adapted to adjust the position of the crusher block along a direction between an inboard location and an outboard location within the crusher chamber; and

c) a yoke assembly joining the outboard face of the crusher block to the adjustment mechanism, wherein the yoke assembly is joined directly to the crusher block and to the adjustment mechanism.

2. A crusher block assembly as recited in claim 1 , wherein the crusher block defines at least one attachment bore configured and adapted to receive a fastener for attaching the yoke to the crusher block.

3. A crusher block assembly as recited in claim 2 , wherein the at least one attachment bore is defined in a flange extending from the outboard face of the crusher block.

4. A crusher block assembly as recited in claim 3 , wherein two adjustable fasteners attach the yoke to the crusher block.

5. A crusher block assembly as recited in claim 4 , further comprising first and second side supports, each side support being attached to a lateral side of the crusher block.

6. A crusher block assembly as recited in claim 5 , wherein the crusher block includes a material chosen from the group consisting of cast iron, cast manganese steel, cast stainless steel, and combinations thereof.

7. A particulate size reduction system comprising:

a) a crushing chamber;

b) a center shaft defining an axis of rotation and configured for rotational motion within the crushing chamber;

c) a wheel assembly mounted on the center shaft within the crushing chamber;

d) at least one swing hammer mounted on the wheel assembly, the at least one swing hammer including a crushing face; and

e) a crusher block assembly including:

i) a crusher block having:

(1) an inboard face configured and adapted to cooperate with the crushing face of the swing hammer in the crusher chamber to crush particulate; and

(2) an outboard face for receiving an adjustment mechanism;

ii)an adjustment mechanism operatively joined to the outboard face of the crusher block, the adjustment mechanism being configured and adapted to adjust the position of the crusher block along a direction between an inboard location and an outboard location within the crusher chamber; and

iii) a yoke assembly joining the outboard face of the crusher block to the adjustment mechanism, wherein the yoke assembly is joined directly to the crusher block and to the adjustment mechanism.

8. A particulate size reduction system as recited in claim 7 , wherein the adjustment mechanism is configured and adapted to be adjusted from outside the crusher chamber to adjust the position of the crusher block relative to the at least one swing hammer.

9. A particulate size reduction system as recited in claim 7 , wherein the crusher block defines at least one attachment bore configured and adapted to receive a fastener for attaching the yoke to the crusher block.

10. A particulate size reduction system as recited in claim 9 , wherein two adjustable fasteners attach the yoke to the crusher block.

11. A particulate size reduction system as recited in claim 7 , wherein the crusher block assembly further includes first and second side supports, each side support being attached to a lateral side of the crusher block.
