Because roller Sieve mill grinders operate at lower speeds and with a different Roller Mill 712 Hammermill 708 kind of reduction action, less noise is generated in the grinding process. In many cases, this reduction in noise means a roller mill grinder will not require a separate enclosure to limit employee exposure to high noise levels.
