By the sand blasting, the rust on the filter frame will be removed, and the surface will be smoother and cleaner. The mechanical performance of the filter press structure will be improved. On the other hand, it’s good for paint. The sand blasting will increase the adhesive force and improve the durability of the paint etc. In a word, it makes the filter press frame to get longer life-span.


Comparing the normal sand blasting technology, our have higher technical requirement and better processing effect: Our spraying material adopts cast iron sand, and the sand size is 0.5mm-1.5mm. The spraying material must be clean, dry and have the corner angle. 2.The distance between the nozzle and the filter frame surface is 100mm ~ 300mm. 3. After sand blasting, the filter frame surface will meet the derusting grade Sa2.5. If want to buy China filter press pls contact us.
