Publication number: 20160175888Abstract: Embodiments of the present disclosure provide for systems, apparatuses, and methods of securing screen assemblies. Embodiments include a system having a compression assembly with a compression pin and a pin assembly having a pin. The compression assembly may be attached to a first wall member of a vibratory screening machine and the pin assembly may be attached to a second wall member of the vibratory screening machine opposite the first wall member such that the compression assembly is configured to assert a force against a first side portion of a screen assembly and drive a second side portion of the screen assembly against the pin of the pin assembly. The pin assembly may include a pin that is internally or externally mounted and that is adjustable and/or replaceable.Type: ApplicationFiled: December 22, 2015Publication date: June 23, 2016Applicant: Derrick CorporationInventor: Christian T.

Publication number: 20150197827Abstract: Embodiments of the present invention include systems and methods that include a sorption vessel containing a pulp including an aqueous slurry and a sorbent, a screening system at least partially submerged within the pulp and including a housing and a vibratory screening machine including a compression assembly and a screen assembly. The aqueous slurry includes a metal that is adsorbed by the sorbent to form an oversized material in the pulp. The compression assembly compresses the screen assembly into a concave shape and the screen assembly is inclined such that the pulp if fed over a first inclined portion of the screen assembly and the oversized materials are conveyed over a second inclined portion of the screen assembly and removed from the system or conveyed back into the sorption vessel. The undersized material passes through the screen assembly into a portion of the housing separate from the pulp and is discharged to another sorption vessel.Type: ApplicationFiled: January 13, 2015Publication date: July 16, 2015Applicant: DERRICK CORPORATIONInventors: David E. Perkins, Christian T. Newman, James R. Colgrove
