Ferrous material buildup can be a concern because it can have a negative effect on both your coolant filtration systems and also the quality of products that you produced. Ferrous buildup can seriously damage your cutting tools and have a negative effect on the cleanliness and quality of your finished parts.
Bag filter systems can help you eliminate this unwanted material within your operations, and many companies across various industries are taking steps to eliminate these problems.
Additionally, magnetic inserts are beneficial to companies that use bag filters in their operations.
These magnetic inserts increase the lifespan of bag filters and also increase effectiveness by preventing the buildup of ferrous material.
Typically a bag filter system removes material from the coolant by the bag alone. Bags, however, have a limit to the size of the particles they can remove. Bags that are sized too tightly will have a negative effect by removing coolant additives in addition to the intended waste. This will also cause them to prematurely blind, increasing the necessary budget for bags.
Magnetic bars are much more effective in this regard as they are able to remove sub-micron magnetic particles that would otherwise pass through the pores of the bag, and limit the overall mass of particulate that even reaches the bag.
Flux should be low so that the fluid has the greatest possible contact time with the magnets. The bag filter system should always operate with a laminar flow in order to maximize fluid contact time with the magnetic bar.
Filtra-Systems bag filter systems that don’t use magnetic bars rely strictly on the bag to filter out ferrous material. Therefore, bags have to be replaced by workers when they have reached the end of their useful life.
Magnetic inserts increase the longevity of the bags by removing particulate before it even contacts the bag. Since the bags are removing less material (because it is being captured by the magnets), they last longer and their lifespan is dramatically increased.
