WEBJul 17, 2017 · The biggest rollers do not necessarily give the best throughput, especially when budget is factored in. If the goal is to run creams or lotions at a decentsize volume, a threeroll mill of 50 mm diameter would be sufficient. For media, such as pastes, which may require a stronger machine, a 65 mm diameter threeroll mill would be suitable.
