How to Determine the Best Cyclone Spigot Diameter & When to Replace It?
Recently, at a copper concentrator, I saw fluctuating classification efficiency. When inspecting the cyclone, a worker pointed at the oval-shaped spigot and said, “This should’ve been replaced long ago!” But when exactly? Let’s solve this grinding headache. The spigot diameter should be 5-10% larger than the theoretical calculation, and must be replaced when wear exceeds […]
