Wear-resistant screen cloth with multiple service life

Significant cost savings – higher system availability

Screen cloth

Screen cloths and the screens made from them are a critical wearing part in screening machines. If the meshes fail, e.g. due to highly abrasive products, this results in production downtimes, product contamination and necessary assembly work to replace the meshes or screen decks. Increasing the service life and prolonging the service life of screen cloths can therefore result in significant savings, both directly by reducing the cost of constantly procuring new screen cloths and indirectly by reducing plant downtime and maintenance work. There is therefore a strong demand for wear-resistant screen cloths.

Want double the service life?

Allgaier supplies new types of wear-resistant screen cloths that offer a service life several times longer than that of previous standard cloths.

For obvious reasons, operators of screening machines are interested in ensuring that the screens, screen decks or screen cloths in the machines have the longest possible service life. After all, if the meshes fail, the production process has to be interrupted, there is a loss of production, the machines have to be dismantled or opened, and the broken screens have to be replaced. So, in addition to the simple cost of...
