Derrick introduced its new G-Vault polyurethane intermediate screen for collecting carbon/resin in the leaching process at the gold recycling plant.
The intermediate screen reduces maintenance work. Due to the tolerance of polyurethane, it eliminates the frequent cleaning and loosening steps required for stainless steel wedge wire screens.
Derrick's G-Vault screen has a 20% higher opening area than the wedge wire screen and produces the same micron density as the wedge wire, reducing processing interruptions and extending the cleaning cycle.
Jeremy Rozelle, OceanaGold senior metallurgist at the Haile Gold Mine, said: After six weeks of use, the company was impressed with the G-Vault screen and decided to install it at every existing screen in the mine.
Rozelle said: "After the first inspection in six weeks, we decided to replace all intermediate screens in our operations with Derrick G-Vault screens."
"This decision was mainly based on its performance. During the first six weeks of use, we did not stop to clean the screen. The performance of the circuit was improved, while also allowing the operator to focus on other tasks. During the entire test process, the test Of the sieve plates have little or no wear."
G-Vault is composed of several independent screen parts. The replaceable part of the screen means that the factory does not need to replace the entire screen like the traditional option, but only replaces the parts with severe wear or damage, thereby reducing maintenance costs.
G-Vault has also been tested in six countries/regions, and some factories have found that the operating time can be extended to more than 18 months without a regular cleaning cycle.
Derrick's G-Vault screens come in a variety of sizes, with screen pore sizes ranging from 500 to 1200 microns.
