The AbrasoBlock® has been developed specifically to improve the performance and reliability of Autoclave Discharge Block valves, thereby increasing operational uptime and capacity. This is one of the most severe service applications and is critical to the economic performance of any HPAL (High Pressure Acid Leach) or POx (Pressure Oxidization) facility. Our goal is to extend the installed lifetime of these valves.
Case Study: Outperforming the competition
Location: Russia
Product: Autoclave discharge block valve
Industry: Mining and minerals
Product: 1 Qty, 1/2” ANSI Class 300 AbrasoBlock® valve
Challenge: To achieve 500 cycles and 50 hours operation without failure of the valve, during an accelerated product trial
Solution: The valve test will take place during the test/elaboration of the autoclave POx- technology of the gold bearing sulphide concentrate into the pilot autoclave line. The purpose of the pilot plant is to test different coating technologies to find a solution for the inherent problems in other valve designs and coating technology during this difficult process.
The AbrasoBlock® integral seat design valve was installed in the pilot plant and trial commenced.
Result: The trial was completed with excellent results. The valve successfully achieved 75.5 hours and 970 strokes of operation. This by far outperforms all other manufacturers’ autoclave block valves trials. The end-user will proceed into commercial supply agreement for valves to be installed in their industrial autoclaves.
