Read OnThe 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 decent-size volume, a three-roll mill of 50 mm diameter would be sufficient. For media, such as pastes, which may require a stronger machine, a 65 mm diameter three-roll mill would be suitable.

Read OnRolling mill is a machine used to roll metals into sheets or bars or different shapes. Rolling metal is similar to the process of rolling dough. In a rolling mill, the metal is passed through one or more pairs of rolls, changing the thickness of the metal into required form.
Read OnTo find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner …
Read OnRolls may operate at differential speeds depending on the task the mill is called to perform. Cracking, crimping and flaking use lower roll (peripheral) speeds - 1,000 Ft/min (5 M/sec) up to 2,200 Ft/min (11 M/sec) and no roll speed differentials. Mills used to grind will operate with higher roll speeds - 1,500 Ft/min (7.5 M/sec) up to 3,000 Ft/min
