A pulverizing dry-washer includes a frame, an upper feeder, a bi-directional pulverizing box, a recovery unit, and a counterweight fan assembly. The upper feeder is angularly attached to an upper end of the frame so that the ore can be screened and discharged into the bi-directional pulverizing box that is positioned below the upper feeder. The bi-directional pulverizing box is mounted onto the recovery unit to further to screen the ore that receives from the upper feeder. A riffle board within the recovery unit is then able to trap precious metal while clay/sedimentary material are discharged through the end of the recovery unit. The counterweight fan assembly is mounted within the recovery unit. An air flow is introduced into the recovery unit via the counterweight fan assembly so that the recovery unit and the bi-directional pulverizing box can be vibrated to separate the precious metal from clay/sedimentary material.

A feed hopper for a material processing device, in particular for a crusher (10), having two side walls (21) and a rear wall of the hopper (22), wherein the side walls (21) are directly or indirectly coupled to a machine support (12.1) in a swiveling manner and can be converted from a set-up work position to a folded-down transport position and back, wherein a feed area is formed between the side walls (21), and wherein at least one of the side walls (21) is supported relative to the machine support (12.1) in the set-up work position by a supporting device (30). A support lever (31), which in the work position is supported directly or indirectly in relation to the machine support (12.1) by a detachable form-fit connection, wherein the form-fit connection prevents the side wall (21) from folding down, projects into the feed area in the folded-down transport position. In this way, a space-saving design is also achieved in the folded-down transport position.

A dual positioned recirculating chute that would allow the operator to run the plant in either closed circuit or open circuit position. While in closed circuit position, the plant will run rock through and the chute will provide as a recirculating chute for oversized rock to travel from the recirculating conveyor back into the feeder hopper for re-crushing. The operator can then reposition the chute to the open circuit position, which will change the direction of the chute away from the feeder hopper and discharge material off the side of the plant. This can be oversized rock material to form an additional stock pile or be redirected to an off-plant conveyor. This can also allow for the removal of trash and unwanted material from the plant cycle without the need for a full plant shutdown, locking out the proper equipment, and manually removing before restarting the crushing process again.

The invention relates to a processing plant, in particular a rock crusher (10), having a filler unit (20,), which can be filled with a material to be crushed, wherein a screening unit (30) is arranged downstream of the filler unit (20) in the conveying direction or in the filler unit (20), which screening unit can be oscillated by means of a vibration exciter (38), wherein the screening unit (30) is used to feed a first part of the supplied material to a process unit, in particular a crusher unit (40) and another part of the supplied material is screened-out in the screening unit (30), wherein a flap (72) of a conveyor unit (70) adjustable about a swivel axis (74.1) is used in a bypass position to feed the screened-out part of the material either onto a conveyor device, in particular a crusher discharge conveyor (60), bypassing the process unit, in particular the crusher unit (40), or, in a conveying position, to discharge the screened-out part of the material from a working area of the processing plant by means of a conveyor device (50), wherein bearing segments (75.1) of a bearing (75) are coupled to opposite sides of the flap (72), which are rotatably installed on the conveyor unit (70). It is suggested that at least one detachable clamping segment (80.1, 80.2) is assigned to at least one of the bearing segments (75.1), which acts in a clamping manner on the assigned bearing segment (75.1) and secures the latter in a swivel position of the flap (72) relative to the conveyor unit (70), such that in the swivel position the flap (72) is secured against rotation relative to the conveyor unit (70).
