Success stories & chamber environments|TestNavi

A settling dust test chamber is simpler. Dust material is placed in a collector, or trough, at the bottom of the chamber, where air nozzles periodically agitate the material, causing a cloud in the chamber. After the agitation, the dust cloud is allowed to settle onto the test sample, which sits above the collector.

 · Gravity settling chambers. The simplest type of equipment for separating solid material from a gas stream is the gravity settling chamber in which the velocity of the gas–solid stream is reduced, and the residence time increased, so that the particles fall out of suspension under the influence of gravity. Such a device is shown in Figure 7.2.

Waelz process - Wikipedia

The Waelz process is a method of recovering zinc and other relatively low boiling point metals from metallurgical waste (typically EAF flue dust) and other recycled materials using a rotary kiln (waelz kiln).. The zinc enriched product is referred to as waelz oxide, and the reduced zinc by product as waelz slag
