The sand blasting uses the compressed air as the power to produce the high speed spray beam. Then spray “sands” to the subject surface to remove the rust. The spraying materials are various, such as: quartz sand, carborundum, iron sand, and so on. For the Plate frame plate frame filter press, we use small steel balls as sand. And this process mainly used for beams, head plates and tail plates.
Sand blasting is very necessary for plate filter press. Generally, before the painting, the metal parts will be processed by the sand blasting. It has following advantages for the filter press quality: 1. increase the painting adhesive force. 2. Make the metal surface smooth and make the appearance much better. So, after sand blasting, the filter press machine can be better painted.
