A gas fluidized-bed stirred media mill is provided for comminuting solid ticles. The mill includes a housing enclosing a porous fluidizing gas diffuser plate, a baffled rotor and stator, a hollow drive shaft with lateral vents, and baffled gas exhaust exit ports. In operation, fluidizing gas is forced through the mill, fluidizing the raw material and milling media.

Effects of Milling on Functional Properties of Rice Flour

Especially in stirred reactors, multi-step synthesis is often performed at different temperature levels. In the fine and specialty chemistry sector, low-temperature process conditions down to and below -100°C are not unusual. For the generation of very low temperatures (below -40°C), cryogenic nitrogen is often the cooling medium of choice.
