Ceramic Cyclone Linings

The separation and classification of even mildly abrasive particles can accelerate abrasion in hydro and air cyclones. The addition of corrosive elements frequently causing traditional materials to fail before expected.

As a global leader in this field with many years’ experience, Saint-Gobain Performance Ceramics & Refractories has designed linings for cyclones across almost every industry, from hydrocyclones to cyclone separators.

The company’s diverse product portfolio can provide excellent cyclone wear life, whether this is in lower wearing areas or areas with accelerated velocity and higher wear.

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.
