    Vertical rolls are ordinarily not driven on a universal rolling mill. Therefore, when trying to apply strong pressure to the flange thickness to make H-shaped steel, etc., if the material comes into contact with the vertical roll first, it increases the possibility of faulty roll bites. This device offsets the center of the vertical roll to the downstream side of the rolling direction relative

    Grinding or particle-size reduction is a major function of feed manufacturing. Many feed mills pass all incoming ingredients through a grinder for several reasons: (a) clumps and large fragments are reduced in size, (b) some moisture is removed due to aeration, and (c) additives such as antioxidants may be blended. All of these improve the ease of handling ingredients and their storability
