Dynamics of fine grinding in a fluidized bed opposed jet mill

Abstract. Today the modeling of the process dynamics and the complex two-phase flows in mills still remain a challenging task. In this study the dynamic comminution process in a fluidized bed opposed jet mill is investigated. For this purpose, well-defined model glass beads were ground in a lab-scale mill. The particle size distributions (PSDs ...

HOW IT WORKS

produces fine powder and coarse particles enter. 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 Milling And Particle Classfication

A pancake mill is a horizontally designed jet mill, while a loop mill is a vertically oriented jet mill. Both are equipped with static classification. The basic differences are highlighted below: While both mills are capable of grinding to 1-10 microns, a pancake mill (e.g. MICRO-JET) will grind a few microns finer (assuming the same processing ...

Types of Jet Mills and Their Differences

The opposed jet mill is a type of jet mill that operates by using two jets of air or steam that are directed at each other. The materials are fed into the center of the mill, where they are ground and milled by the opposing jets. The opposed jet mill is typically used for grinding and milling materials that are abrasive or have a high hardness.

How does a jet mill work? | FPS

The powder, forced into the chamber by an injector and a venturi system, is moved by the internal high-pressure gas at almost supersonic speeds. The combination of high speed, centrifugal and centripetal effects crush the particles. The resulting fine particles are selected by a classifier ad leave the jet mill, moved by the same process gas ...
