What is priming exhaust? Zhengzhou Batt double column screen
As a decades-old screen changer manufacturer, Zhengzhou Batt has developed and manufactured a large number of high-quality plate and double-column hydraulic screen changers (melt filters) for the plastics machinery and chemical industry in China, providing a complete set of perfect melt filtration solutions. The double-column screen changer provided by Zhengzhou Barth has obvious advantages such as small size, low energy consumption, easy screen replacement and low material and labor loss. For what is priming exhaust, Zhengzhou Batt screen changer manufacturer elaborates one by one in the following. Translated with www.DeepL.com/Translator (free version)
When replacing a screen with a new screen in a double column screen changer, some of the material is removed and a certain amount of air is brought into the screen changer plunger in the screen plate area, which requires a priming and venting operation to remove the air from the plunger. When pushing the new screen into the main body of the double column screen changer, it is necessary to operate the screen changer plunger to stay in the priming and venting position for a moment, the purpose is: to draw a small flow of material from the production runner to discharge the air from the plunger to avoid air mixing in and causing product quality problems. In the process of inducing the material exhaust, it can realize the preheating and warming up of the new mesh of the plunger at the same time, and avoid the temperature fluctuation of the mesh area during the process of changing the mesh.
