Modelling fine grinding in a fluidized bed opposed jet

An overall model of a continuous grinding process is proposed which combines experimentally-determined breakage kinetics, a model of solids flow in the active zone and the grade efficiency curve of the classifier. This model is developed and tested for an Alpine 100 AFG fluidised bed opposed jet air mill with an integral classifier.

Effects of grinding parameters on product fineness in jet

1998-11-1  In these cases ultra fine grinding is needed as final processing. Ultra fine grinding is a unit operation process where particles are ground to a fineness where 8t)% of the particles are smaller than 1-10 i~n. Mills often used for ultra fine grinding are the attrition mill and the jet mill [1,2].

s-Jet Steam Jet Mill NETZSCH Grinding & Dispersing

The new s-Jet ® System is a consequent further development of the air-jet mill based on the Fluidized Bed Jet Mill CGS. Using steam instead of air, a considerably higher jet energy is made available whereby higher capacities and new ranges of fineness (submicron) can be achieved in the area of dry grinding.

2021-10-22  Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill

Jet mills (also called air jet mills) have a special feature: they do not need mechanical grinding tools. Instead, the particles are crushed and ground in a gas stream by repeatedly colliding with each other there. Jet mills are an excellent choice in industry when ultra-fine grinding

The Jet Pulverizer Company How Jet Mills Work : Jet

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process

Dynamics of fine grinding in a fluidized bed opposed jet mill

Due to imperfect classification, particles accumulate inside the mill which is further enhanced by a high holdup of fine particles. Our results clearly show that the classification and transport processes must be studied in detail for any in-depth understanding of dry fine grinding in fluidized bed opposed jet mills.
