WhatsApp: +86 18838072829This machine consists of three rolls each of which has a different revolution speed. Material is processed by the compression effect produced by the pressure between rolls and by the shearing effect produced by rolls with different revolution speeds. Three Roll Mill is best suitable for processing materials with medium to high viscosity.

Each of the adjacent rolls differed in their rotation speed by 200%, the absolute speeds being m/sec for roll 1, m/sec for roll 2 and m/sec for roll 3.
WhatsApp: +86 18838072829Three Roll Mills. EXAKT three roll mills are used in a wide variety of industrial and research applications. They can break open all kinds of agglomerates creating fineness and quality in each dispersion. Customize your mill by choosing between five models, various roller diameters, roller lengths, and roller materials.
WhatsApp: +86 18838072829By symmetry, the number of outcomes where roll 2 > roll 3 > roll 1 is also 20. Finally, we need to count the outcomes where (roll 2 = roll 3) > roll 1. This is the same as the number of outcomes for which roll 2 > roll 1 in the 2dice case (hence the hint), which we established is {6choose2} = 15.
