Roxia Tower Press

Roxia Tower Press (TP) is a fully automatic pressure filter excellent for any process that requires efficient solid-liquid filtration. The design follows 40 years of respected experience in the field. Roxia Tower Press filter is a reliable production machine that delivers high performance over and over again. Horizontal pressure filtration technology provides the following benefits:

  • Uniform cake formation in the chamber enables efficient cake wash and air drying.
  • High-pressure diaphragm pressing ensures a more even and drier cake.
  • A single and continuous cloth design ensures a fast and reliable cake discharge without operator intervention.

Complete filtration support

Roxia can also provide detailed analysis of process, filtration testing, equipment selection and sizing for this and other kinds of mining filters needed for solid-liquid separation. Get complete service through the entire filter life cycle, modernizations, refurbishments, spare parts and maintenance support.

Filtration Testing and Process Support

Testing the slurry is essential before choosing the correct filter type and size. Whether we are talking about plate filters, mining filters or other applications. In this way, we can ensure the best possible process performance and the most cost-efficient solution for each application. Filtration testing can be done on-site or in the Roxia filtration laboratory.

We only require a minimum sample of 20 litres  of slurry or 20 kg of dry solids.

Obtained filtration test results:

  • Recommendation of the most suitable filtration technology
  • Optimal filtration parameters
  • Filtration capacity, kgDS/m²
  • Cake moisture
  • Filtrate clarity
  • Cake washing efficiency (optional)
  • Filter media recommendation based on test results

Enhanced Process with Smart Filtration

Roxia connects the automatic filter press to the Roxia Malibu online portal and enables remote monitoring of performance. With Smart Filtration, operators can optimize filtration process, increase production volume and detect failures before they even occur. All that can be done from anywhere with any computer, smart phone or other handheld device with internet connection.

  • See-through construction minimises the need to open the door and approach the filter.

Safe working at height

  • Caged ladder with fall arrest system.
  • Railings around the top maintenance platform.
  • Lifts for safe and ergonomic service of the plate pack area.

Safe use

  • Filter comes with a user manual including safety instructions for safe operation and working procedures.
  • Before starting to use the filter, operators and maintenance crew receive safety training.
  • The operator interface guides users to safe use during daily operation. It also includes warnings about possible safety threats.
  • Password-protected user roles secure critical filter parameters.

Easy and safe maintenance

  • Filter cloth change happens at only one access point outside the filter.
  • Filter design includes extra space around the filter and enables an easy approach.
  • Check and maintenance points are easily accessible and away from the most corrosive areas.
  • Included remote handheld unit for safe maintenance and troubleshooting.
