Roughness of the inner wall of the equipment
Thread Content
Inside the equipment, such as silos, cyclone dust collectors, and bag filters, is it difficult to increase the internal surface roughness from Ra0.8 to Ra0.4? Does this have much of an impact on costs? Experienced users, please share some information. Also, what are the main methods used for internal polishing, and is a large amount of labor required for manual grinding?
Polishing the inner surface of equipment that has been assembled and installed requires many conditions: scaffolding to be set up inside the equipment, permits for working at heights, working in confined spaces, etc., as well as a power source for polishing. Compressed air source or power supply; good ventilation ； Professional polishers, standard construction procedures. Refined security measures. For roughness testers used in quality inspection, it’s not difficult to raise the standard from Ra0.8 to Ra0.4; if the equipment is manufactured in-house, simply use another batch of units, which has little impact on costs
