Filters for Mineral Processing

Chemical Plant & Engineering is a world leading designer and supplier of filtration solutions to the Mineral Processing sector across the globe. CPE offers a range of vacuum and pressure filters for mineral processing applications.

With over 50 years of design experience, we understand the process requirements of this industry.

Rotary Drum and Horizontal Pan Vacuum Filters

CPE rotary drum and pan filters are ideal for continuous filtration of medium to coarse solids at large capacities.

These filter types are a great fit for slurries with moderate to high solids content (2-40 wt. %). Pan filters are favoured if cake washing is required.

We can design a complete filter aid mixing system in combination with our filtration solution.
