Derrick SuperStack

Derrick® Corporation has once again redefined high capacity, high efficiency, fine particle wet screening with the introduction of the SuperStack®. With 8 decks operating in parallel and innovative Front-to-Back (FTB) tensioning system, the SuperStack has a demonstrated capacity up to 3 times that of the best fine screens currently available. All of this added capacity comes with only a slight increase in the space required per machine, significantly reducing the total capital and installation cost as well as OPEX for any screening installation. Customers using the Derrick SuperStack report significant capacity increases over their previous screening equipment. These increases are attributed to the rotation of each screen section’s crown 90 degrees, parallel to material flow. This change in crown direction assures an even distribution of material across the entire width of the screen and engages 100 percent of the screening surface. It also minimizes migration of oversize particles to the outside edges of the screening deck. This even distribution of material leads to increased panel life by reducing panel wear caused by oversize solids conveying in concentrated areas | The G-Vault ® Complete Interstage Unit is the newest addition to the Derrick portfolio and now serves as the new standard of interstage screening in loaded Carbon and Resin circuits, unique to gold recovery. Our newest innovation employs a modular approach where a screen surface is combined with a robust support structure that can be connected with ease. Trilogy screens feature tapered openings, can withstand higher temperatures, and increased open area which all contribute to its non-blinding characteristics. These non-blinding and abrasion resistant properties result in a screen with higher throughput, increased life, and less maintenance. All of which lead to more efficient recovery. Prioritizing HSE, Derrick has focused the G-Vault design on operator safety. The G-Vault utilizes a compression seal drain on the bottom of the unit, eliminating unnecessary moving parts. An optional draft tube can be incorporated for pumping applications. This option operates on a standalone drive system which is accessible from the top of unit. Additionally, each screen on the G-Vault unit can be easily removed while connected to the launder due to its modular design – all of which lead to a reduction in working under suspended loads.
