Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or nonstraight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

 · Cement ball mills can be divided according to discharge method: grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions. 【Cement mill structure】 Ball mill is mainly composed of feeding part, supporting frame, rotary part, discharge, transmission, lubricant and cooling part.

SAG mills grind ore by lifting it and a small amount of grinding media and dropping it inside a horizontal mill. Ball mills are smaller and use a higher concentration of iron balls to pummel the ore. The mills can operate in an open grinding circuit, feeding secondary grinding systems, or in a closed circuit generating a fine product.
