Tower press filter fabrics

Filter fabrics execute most of the work at the heart of the tower press, producing clear filtrate and cake with a low moisture content. The performance of the fabric affects the overall production capacity and makes a difference in the productivity of the whole plant.

Valmet offers high-quality products, solutions and services for all tower press applications, also known as automatic pressure filters. Robust Valmet Tower Press Filter Fabrics ensure maximum production performance in many of the world’s largest mining and metallurgical operations.

Our filter fabrics result in significant costs savings in filter cloths as well as enhanced productivity thanks to more durable cloth, higher filter availability and more reliable runs.

Belt filter fabrics

Belt filter fabrics for horizontal vacuum belt filters, belt press filters, linear screens and conveyor belt applications improve dryness, enable faster speeds and reduce energy consumption. Valmet’s product range offers a solution for any filtered particle size, including dense multifilament fabrics, needled felts, double layer weave and horizontal vacuum belt filter fabrics.

Valmet's strong horizontal vacuum belt filter fabric is a heavy monofilament fabric for the filtration needs of the chemical and mining industries. Its heavyweight fabric made of special yarns that prevent blinding extend belt lifetime, making it ideal for belt press filters. It allows rapid draining and good filter cake release. 
The double-layered fabric for horizontal vacuum belt filters combines high flow capacity and fine particle capture with a durable construction, covering various chemical and mining industry applications. Its main benefits include lower cake moisture, higher capacity and longer running time, strong edges and seams, and stable runnability without creases.

Press filter fabrics

Valmet offers high-quality press filter fabrics for vertical plate pressure filters (VPA) for filtration of metal concentrates, industrial minerals and tailings, and for filters in fast-opening filter presses (FFP) for bulk mining. A computer-controlled laser cutter with coded dimensions ensures a perfect fit and absolute precision in even the most demanding applications.

Superior filtration results with filter fabrics for vertical plate pressure filters (VPA)

A VPA is a heavy-duty filter engineered for dewatering metal concentrates to low moistures. Valmet offers a complete range of capacities in three frame sizes. VPA filter cloths provide excellent cake release and are available in needled, monofilament, and multifilament versions according to your application. High-capacity VPA filter cloths provide your application with a perfect fit and long lifetime, low cake moisture, and less fabric blinding. Valmet’s VPA filter cloths include clear color codes for easy installation.

Efficient bulk mining with filter fabrics for fast-opening filter press (FFP)

Fabrics for bulk material dewatering offer reliability in high-capacity production environments. Fast-opening filter presses are widely used in mining operations that have strict requirements for the disposal of tailings. These challenging dewatering processes show an increased need for high-quality filter fabrics.

Filter bags resulting clear filtrate and excellent cake release

Disc filter fabrics

Valmet is the global market leader in disc filter products such as filter bags and plastic sectors. Today, most of the leading mining companies and disc filter manufacturers use Valmet’s disc filter products and services. With easy installation and a perfect fit, Valmet’s plastic sectors, disc filter bags, and easy fix caulking rubbers provide high capacity and durable filtration solutions.

Drum vacuum filter fabrics

Vacuum filtration is used in industrial dewatering. Valmet’s drum filter fabrics endure high air flow rates in the belt drum and top feed drum filters and provide the best technical and economical filtration results. High-quality drum filter fabric structures help our customers to meet their demanding needs for performance, quality and energy savings. Valmet’s drum filter fabrics provide significant, long-term savings in mining and chemical processes.

Filtration support through on-site filtration test

Valmet’s compact and portable laboratory filter equipment enables to determine quickly and easily the filtration performance using customer's own slurry. Taken and analyzed on-site, even a small material sample is enough to reliably measure the performance of different filter media.

In addition, Valmet’s new Industrial Internet application for stock monitoring enables inventory optimization, production and procurement planning. The app for filter cloth performance optimization gathers and analyzes data from machines and processes, utilizing it to adjust operations and plan predictive maintenance to positively affect the value chain. The application enables our experts to remotely offer filter cloth technology support and results in clear savings through automatic analysis of operation data as well as supply chain and performance optimization.
