How to resolve the most common hydrocyclone problems
· We often find the mill size and installed horsepower is insufficient to process the quantity of new feed being sent to the mill. There can also be issues with the size, quantity, or quality of the balls and volume charge, or even the condition and geometry of the mill's wear lining. Ore hardness also affects mill circuit operation.
