FAQ
Is it normal for the coarse discharge of a hydrocyclone to experience more rapid wear than other parts of the cyclone?
Yes, this is a common issue. It is advisable to upgrade materials in this area to a higher-performing ceramic to address this issue.
What is the best approach to addressing higher wear on the inlet of a dust collection cyclone?
A ceramic panel can be designed to address this specific wear zone in the cyclone. This panel features a bolt-in design, ensuring that the inside surface of the cyclone remains smooth and consistent.
