Filtration of tile adhesive with FG Automatic metal edge filter AF 43

Strict environmental and safety regulations apply in the chemical industry. Reliable and high-performance filtration creates the prerequisite for both standard-compliant and profitable production. FG edge filters clean raw materials that are required, for example, for the production of tile adhesives. Components such as cement, sand and other additives form the basis for modern tile adhesives. The various raw materials are weighed out in quantity and mixed homogeneously. In order to test the properties in practice, various tests are carried out in the laboratory. These include tensile adhesion tests to examine loads in wet or frosty conditions. The flexibility of the adhesive is tested with the aid of a mortar strip. In the industrial production of tile adhesive, the individual raw materials are mixed and filled into bags.

Challenge

Filtration Group Industrial’s customer is part of a global specialty chemicals company. Under the brand, solutions in the field of bonding ceramics and floor coverings are offered to professional processors. The product range includes tile adhesives, flooring adhesives, grouts and fillers. In the manufacturing and production process, the adhesives were previously filled using simple bag filters. Due to the technology involved, this resulted in a high consumption of filter bags and, because of the nature of the product, a corresponding level of product rejects. The manual work involved in changing the bags is not inconsiderable.

Technical data

  • Flow rate: 15 – 18 m³/h
  • Retention rate: 500 µm
  • Operating pressure: 7 -8 bar
  • Operating temperature: ca. 35 °C
  • Material: stainless steel, 1.4571

Solution statement

  • Filtration Group has selected for this kind of application an automatic metal edge filter type AF 43 with perforated edge foil elements

  • Due to the nature of the product, a highly viscous thixotropic material with varying dirt load, the filter elements are permanently turned against 3 scrapers each
  • The particles to be cleaned off are gel-like agglomerates
  • The filter construction was chosen in such a way that the unit can be dismantled into several parts to ensure that the components can be cleaned as easily as possible

Customer value

  • No need to change filter bags
  • Significant cost savings by eliminating the disposal of consumables
  • Considerable reduction of product loss by more than 85 %; corresponds to approx. 20 kg per bag change
  • By eliminating the need to change the filter bag and thus reducing the downtime of the plant, the total throughput could be increased significantly
