ASABE Technical Library :: Abstract

Keywords: Grinding, Size reduction, Rittinger, Bond, Kick, Energy consumption, Specific energy consumption, Particle size, Biomass Size reduction is an essential and often first operation in preparing biomass for subsequent operations. Size reduction is energy intensive especially for cases where the target particle is small and precise in dimension. Mineral and food industries have developed ...

This gave a Rittinger's constant of 28 J.m/kg for the given system. Using this value of Rittinger's constant, the energy required to generate microfibres 1 μm in diameter was predicted as 2480 kJ for each 24 g charge in the PFI mill. It was deduced that microfibres generated in this way would cost a minimum of $2.37 per kilogram. Hence even this relatively inefficient method of grinding ...

WikiZero - Mill (grinding)

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 ().

Occupational Safety and Health Administration

On offhand grinding machines, work rests shall be used to support the work. They shall be of rigid construction and designed to be adjustable to compensate for wheel wear. Work rests shall be kept adjusted closely to the wheel with a maximum opening of 1/8 inch (0.3175 cm) to prevent the work from being jammed between the wheel and the rest, which may cause wheel breakage. The work rest shall ...
