Since cement is usually loaded pneumatically, the amount of air that is integrated in the cement must be accounted for to avoid overfilling of the silo. The following data can be used to determine the silo capacity needed. 1 Barrel of Cement = 300 lbs of blown in, or "fluffed" cement. 200 Barrel Silo – Loaded Capacity of 60,000 lbs / 30 tons

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Those mills can have from 3 up to 6 rolls; every set of mills is called a tandem mill or mill train. To improve the milling extraction efficiency, imbibition water is added at each mill. Hot water is poured over the cane just before it enters the last mill in the milling train and is recirculated up to reach the first mill.
