Yes. I've talked with Favagrossa and they advice to set the speed of the top brushes at 120rpm's. The problem is that I would like to obtain the same theorical result. Thanks!.

Yes, it is always the same old song. In my case, the brushes clean trams and trains of several million dollars, and the customers ask for the softest fibers to take care of their vehicles and bodies. I attach a picture with brushes turning around 100rpm. As you can see, they need more speed, and...

Hi. First at all, thanks for your response. Of course the material is basic to solve the question. Sorry, I forget to mention that I use to work with Favagrossa Filok brushes (the best in my opinion), formed by LDPE fibers that need higher spins than other ones to raise. Maybe I can try with...

Hi all. I'm trying to develop a transversal brush, and first I have to know the minimum rotation speed to keep the fibers straight. In this way, I've tried to calculate it through the tipical formula of a U.C.M system, but it doesn't works because the result obtained is higher than the empiric...
