Trilogy Surface Technology

Guided by innovation and anchored in tradition, Derrick has spent the past 35 years perfecting fine screening solutions for the mining industry. With aperture sizes as fine as 38 micron, all with superior performing open area and cut points, Derrick is the recognized leader in applying urethane technology to screen surfaces. Our newest innovation employs a modular approach in which the screen surface is combined with a robust support structure that can be joined together easily. This modularity gives us the ability to increase screening area in the same footprint. Trilogy screens feature tapered openings which highlight its non-blinding characteristics, the ability to withstand higher material temperatures and increased capacity. Trilogy carries on the pedigree of its predecessor’s extended service life and high open area. All of which lead to increased gold recovery. With the development of Trilogy, Derrick has succeeded in maintaining its incumbency as the industry leader in fine screening solutions. | 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.
