Visual Encyclopedia of Chemical Engineering

Unlike most types of mills, cone mills can be used for hard to grind products while using less energy than other types of mills. Cone mills are preferred in some industries because they produce less noise, dust, and heat than traditional milling equipment. Equipment Design Material is fed into the conical chamber by gravity or conveying it.
