A shaker screen comprising a panel defining a plurality of openings therein, the panel having an upper surface and a lower surface. A plurality of mesh screens is attached to the panel, and separately formed side rails are connected to the panel at first and second sides thereof. The side rails have a connecting hook at a first end thereof and a receiving slot at a second end thereof. The receiving slot is configured to receive the connecting hook at the first end of a side rail of an adjacent shaker screen and the receiving slot is covered by the panel.

A screening machine includes wall members, screen assembly guide members, a screen assembly and a compression assembly. The screen assembly includes a frame with a plurality of side members and a screen supported by the frame. The compression assembly is attached to at least one wall member and forms the screen assembly into a concave shape.

A slurry management system. The slurry management system may include a screen assembly and an RFID reader. The screen assembly may include a shaker screen and RFID tags arranged on the shaker screen. The RFID reader may be positioned to read locations of the RFID tags.

To provide a mesh member such that a static charge can be suppressed.

Provided is a mesh member including a mesh woven fabric and a coating layer that is formed on the surface of the mesh woven fabric and contains a carbon nanotube and/or graphene.

A sieve is disclosed for use in a plansifter. The sieve can be changed between backwire and combined sieve configurations without the height of the sieve changing, and while maintaining contact between a frame of the sieve and the sieve box. A dynamic combined cleaner also is disclosed in which the center of gravity of the cleaner dynamically changes based on inertial movements applied to the cleaner.

According to embodiments described in the specification, an exemplary method is disclosed for hydraulically hoisting potash (or other evaporite ore) fines material from an underground mine. The method includes mining an ore deposit using a boring machine to generate Run-of-Mine (ROM) material at a mine face, conveying the generated ROM material to an underground ore screening plant, screening the ROM material relative to a threshold size wherein the threshold size is a feed size of one or more flotation cells at a surface processing plant, mixing fines material, comprising ROM material that is below the threshold size, with a saturated brine to create a slurry mixture wherein the saturated brine prevents the fines material from dissolving into the slurry mixture, and pumping the slurry mixture to a surface location via one of a shaft and a borehole to the surface product separation plant.

A mobile sieving apparatus and method for harvesting cannabis pollen and trichomes separates the flowers of a cannabis plant. A large sieve panel, a medium sieve panel, a small sieve panel, and a silk screen panel are arranged in a spaced-apart stacked arrangement inside a harvesting vehicle. The sieved panels have different sized openings to enable passage of corresponding portions of the cannabis plant. The sieve panels are arranged by graduated separation, in which the distance between panels correlates to the size of the cannabis plant components passing through the opening. A harvesting panel has a solid, flat surface, and positions below the sieve panels to catch the pollens and trichomes falling through. The panels are stacked in a harvesting vehicle, sliding onto docking rails that slidably receive the edges of panels. The harvesting vehicle is lightweight to enable manual agitation of the vehicle, and enhance mobility of the panels.
