Description
In the ceramic tiles prodcution, engobes, grits, and glazes are still applied - to a large extent - by means of airless spray systems.chine is equipped with spraying guns that end with special nozzles that properly discharge the suspension on the raw ceramic surface. Sometimes these nozzles can be clogged during application stage, forcing producers to slow down or even stop the production cycle.The problem, that has a significant and negative impact on the industrial productivity, can arise because of several scenarios such as a wrong set-up of the application machine, an improper grit grain size or the presence of localized sedimentation phenomena.In detail, what are the mechanisms that can lead to the problem and what do you need to know to take the right actions to prevent it?
