The plastic mesh pad for vacuum drum filters serves as a core component that acts both as a support and a filtering medium. It helps distribute materials evenly, prevents filter cloth clogging, and ensures stable filtration performance.

A plastic mesh pad is a grid-shaped filtering component or auxiliary filtering medium made from polymeric materials, with the following characteristics:

Lightweight, corrosion-resistant, and cost-effective;

Stable structure and resistance to deformation;

Low fluid resistance and high filtrate passing rate;

Reusable with a long service life.

Applications of Plastic Mesh Pads in Vacuum Drum Filters

As a Support Structure

Supporting filter cloth: Laid on the drum surface, it provides uniform support for the filter cloth to prevent deformation or damage.

Enhancing structure: Improves the mechanical strength of the filtering medium and extends its service life.

Improving filtrate flow: Creates fluid channels to reduce filtrate flow resistance and boost filtration efficiency.

As a Primary Filtering Medium

Installed directly on the drum, it is used to treat liquids containing large particulate suspensions.

Suitable for scenarios with low requirements for filtrate clarity, such as mineral tailings and wastewater pretreatment.

Composite Applications

Used in combination with filter cloths or membrane materials to form a multi-layer filtration system.

Common forms: Plastic mesh + filter cloth, plastic mesh + microporous membrane, which enhance filtration efficiency and precision.
