An apparatus for separating and sizing particulate matter, comprising a main frame, infeed conveyor, collection conveyor and a screening assembly including a frame, screen, and an underscreen conveyor mounted underneath the screen. In exemplary embodiments at least one crusher is included. The apparatus converts configuration from a transport mode to an operating mode. Material deposited onto the infeed conveyor is moved forward into the screening assembly. Material falling through the screen is deflected by a deflector onto a collection conveyor. Material passing over the screen drops into the crusher and crushed material drops onto the collection conveyor. Material on the collection conveyor is conveyed to a discharge location. The apparatus components are arranged such that material moves in a uni-directional flow through the apparatus without reversing direction. The apparatus may be mounted on a mobilizing assembly, such as one including endless tracks or wheels, for portability. |

1. An apparatus for sizing and separating particulate material, comprising;
a. main frame having an elongated generally rectangular structure and having a infeed end section and a discharge end section, the main frame having a longitudinal axis generally extending from the infeed end section to the discharge end section; b. an engine associated with the main frame; c. an infeed conveyor mounted to the main frame proximate to the main frame infeed end section, the infeed conveyor having an input end and an outflow end; d. a collection conveyor associated with the main frame, the collection conveyor having an receiving section and a discharge section, the collection conveyor, when in an operating mode, being generally parallel to and in line with the longitudinal axis; e. a screening assembly associated with the main frame and comprising
i. a screening assembly frame having a first end and a second end,ii. a screen unit associated with the screening assembly frame,iii. a screening conveyor disposed substantially under the screen, the screening conveyor having a receiving end associated with the screening assembly frame first end and a discharge end associated with the screening assembly frame second end, the screening assembly first end being positioned proximate to and at least partially underneath the infeed conveyor discharge end, such that particulate material being discharged by the infeed conveyor discharge end is conveyed into the screening assembly proximate to the screening assembly first end, whereby smaller particulate matter passes through the screen, and whereby larger particulate material passes over the screen unit toward the screening assembly second end,iv. a positioning mechanism associated with the main frame and the screening assembly frame for moving the screening assembly from a transport mode first position to an operating mode second position, the mechanism comprising at least one height-adjusting element associated the screening assembly that can be operated to increase or decrease the height of at least a portion of the screening assembly with respect to the main frame,wherein material is discharged off the discharge end of the collection conveyor.
