A device and system applicable to separating components of a slurry is disclosed. The slurry can be a mixture of drilling fluid and drilling cuttings that can be separated with a separatory screen. A separatory tray can be disposed below an underside of the separatory screen. A pressure differential pan can provide fluid flow to a sump. A pressure differential generator can be located within the pressure differential pan and create a pressure differential between an upper side and a lower side of the separatory screen to enhance the flow of drilling fluid through the separatory screen.

An item of equipment for separating bagged waste has a hopper, separation means for separating the waste, a scanner for classifying the waste, elements for opening the bagged waste, chutes with gates, classification means, an artificial vision camera, and a plurality of shredders. Thus, the shredders are able to shred the waste subsequent to the classification thereof by type of polymer and color, thanks to the artificial vision camera. The equipment enables the individual separation of the bagged waste for the subsequent treatment thereof, as frequently some bags of waste are adhered to others.

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.
