An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the …

The VSK separator is one such classifier that operates on the principle of dynamic air classification. It consists of a horizontal rotor cage mounted on top of the V-section. In VSK separator, particle separation is achieved by adjusting the air flow rate and rotor speed (Strasser, 2003). The literature on dry beneficiation of industrial ...

g = viscosity of the gas (air) Vrad = radial speed of the gas (air) R = radius of classifier wheel n = speed of classifier wheel (rpm) In general, the centrifugal forces within the air classifier are typi-cally imparted by a high-speed re-jecter rotor, also known as a clas-sifier wheel. The particles that are introduced into the classifier are

Overview -- Rubidium is a soft, ductile, silvery-white metal that melts at 39.3 ?C. One of the alkali metals, it is positioned in group 1 (or IA) of the periodic table between potassium and cesium. Naturally occurring rubidium is slightly radioactive. Rubidium is an extremely reactive metal--it ignites spontaneously in the presence of air and …

Air Classifiers Overview Sturtevant Products - Know More. Air Classifiers For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment...

The classifier is called as dynamic type owing to its rotary part. The feed rate of the air classifier is in range between 2 and 6 kg/h, which is the function of bulk density. Rotor speed varies between 2500 and 15,000 rpm and air flow rate is in range between 5 and 30 m 3 /h. The target size of the classification can be adjusted with the air ...

Air classification is a technological method of separating particulates according to their size, as represented by particle equivalent diameter [1]. The latter may …

Prater Air Classifiers are designed to provide ultra-fine separation and narrow particle distributions for dry bulk materials. Our air classifiers offer size separations in the …

Dynamic air classifiers. A dynamic air classifier uses the principles of elutriation, drag force, and centrifugal force to separate materials into coarse and fine fractions. A dynamic air classifier can classify a wide range of materials with particle sizes from 3 to 100 microns and can operate either inline or offline, depending on the process.

The vortex finder configuration is displayed in Fig. 1.The base classifier is equipped with the partly-inserted vortex finder (PI-VF). To reduce the particle short-circuiting and increase the particle classifying time, the fully-inserted vortex finders with one slot and uniform four slots are designed, named non-uniform slotted vortex finder (NS-VF) and …

Gravitational inertial air classifiers use a primary and a recirculating secondary airflow to separate fines from coarse particles. Because the airflows are not affected by wear, the grading remains consistent to an accuracy of microns. At the same time, particle moisture remains at an optimal level. Different fractions ranging from 300 μm to ...
