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.
