Do you sometimes find it annoying when creams splash out of your ointment mill? Just follow the tips below to check for possible causes. It is a problem rather easy to prevent.
1. Set suitable gap sizes.
Usually the speed of the front roller is much faster than that of the rear roller. In order to balance input and output, we recommend setting the rear gap size larger than the front gap size. However, if the rear gap size is too much larger than the front, it might lead to a larger input than output. As a result, the creams will splash out of both sides of the rear gap. For THT’s T50 ointment mill, an ideal gap setting would be “1” for the front roller and “3” for the rear roller.
2. Check the condition of the plastic guides and the scraper.
If the plastic guides are not sitting on the rollers properly, there will be tiny gaps between the guides and the rollers through which the cream may leak. Likewise, if there is a gap between the front roller and the scraper, the cream cannot be collected sufficiently, which again leads to a larger input than output. So always check the plastic guides and the scraper before running the mill.
3. Lower the speed if necessary.
When running at full speed, the ointment mill is able to process more of your product in a given time period, meaning higher output and better productivity. However, thin creams tend to splash more easily, because they could not adhere to the rollers as firmly as the thick ones do, especially when the rollers are rotating at a high speed. Therefore, slowing down the mill could reduce the risk of splashing in some cases.
Just a few simple steps could help reduce waste and make compounding happier. Everyone could become an expert running an ointment mill!
