  • Mill (grinding)Wikipedia

    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 (). How to Read a Cement Mill Certificate Part 1 With such multi-component raw materials it is impossible to keep all composition factors the same. So the cement characteristics will vary as will the characteristics of all concrete components. Where the alkali occurs in the cement can affect this but to get a first approximation we
