Description: |
| Abstract:
In the art to which this invention relates it is well known that the frame portion of the crusher consists generally of a lower portion, an upper shell portion that contains and holds the crushing-concaves, and a spider portion, and that the crushing-concaves always wear out at the lower portion thereof, so that when such lower portion is worn the concaves have to be thrown away. Our invention is intended, therefore, to obviate these objections and provide a crushing-frame of practically two parts, in which the shell is positioned by the clamping together of the spider and main frame, and the shell and its crushing-concaves may be inverted, so that its upper and lower portions may be presented as the working surfaces in order to compensate for the wear.
Claim:
In a rock and ore breaker, the combination of a main body or frame portion, an annular frame or shell removably and reversibly secured in the main body portion, and crushing-concaves removably secured in the annular shell. |
