    In the aftermath an analysis brought to light a design problem with this salt mill and I believe the pepper mill which appears to be exactly like it. The center post which holds the grinding gear is spring loaded (nothing odd there really) and is held in the mill by an aluminum square with a hole in the middle which is press-fit onto 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 ().
