Abstract
A portable screening and washing assembly includes a frame, and in addition, a scrubbing mill, a vibratory screen assembly and a fine material washer, all of which are mounted on the frame. Both the scrubbing mill and the fine material washer are adapted to move between a transport configuration and an operational configuration.
Claims20
A portable screening and washing assembly comprising:
- (a) a frame having a wheelset;
- (b) a scrubbing mill that is mounted on the frame and adapted to move between a transport configuration and an operational configuration;
- (c) a vibratory screen assembly that is mounted on the frame;
- (d) a fine material washer that is mounted on the frame and adapted to move between a transport configuration and an operational configuration;
- (e) means mounted on the frame for moving the scrubbing mill between the transport configuration and the operational configuration;
- (f) means mounted on the frame for moving the fine material washer between the transport configuration and the operational configuration.

A portable screening and washing assembly having a front end and a rear end, said assembly comprising:
- (a) a frame having a wheelset;
- (b) a scrubbing mill that is mounted on the frame and adapted to move between a transport configuration and an operational configuration;
- said scrubbing mill being:
- (i) mounted above the fine material washer in the transport configuration;
- (ii) mounted nearer to the rear end than the front end;
- (iii) adapted, in the operational configuration, to process an aggregate slurry mixture, thereby producing a processed aggregate mixture;
- (iv) adapted, in the operational configuration, to discharge the processed aggregate mixture into the vibratory screen assembly;
- (c) a vibratory screen assembly that is mounted on the frame, said vibratory screen assembly being:
- (i) mounted nearer to the front end than the rear end;
- (ii) adapted, in the operational configuration, to separate aggregate materials of various particle sizes from the processed aggregate mixture discharged from the scrubbing mill;
- (iii) adapted, in the operational configuration, to discharge aggregate materials into the fine material washer;
- (d) a fine material washer that is mounted on the frame and adapted to move between a transport configuration and an operational configuration, said fine material washer being:
- (i) adapted to dewater aggregate materials received from the vibratory screen assembly;
- (ii) mounted nearer to the rear end than the front end.
