The aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. Experiments were planned following a central composite design (CCD), considering refining time (rt) and agitator shaft speed (as) as experimental variables measured were chosen from the main characteristics that describe unmoulded chocolate.

Quantum Nanostructures (QDs): An Overview. D. Sumanth Kumar, ... Mahesh, in Synthesis of Inorganic Nanomaterials, 2018 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating ...

Milling is an essential unit operation used for particle size reduction in solid oral dosage manufacturing. The breakage of particles in a comil is due to the intense shear applied on the particles between impeller and the screen. Breakage also occurs due to the impact from a rotating impeller. Particles exit the mill based on their size relative to the aperture size of the screen bores. This ...

The obtained labscale parameters were scaledup using an empirical scaleup equation based on the industrial plant conditions. Using the obtained particle size distributions, the reduction ratio based on the 80% passing size was calculated to be for the first ball mill, while it was only for the second ball mill.
