Air Classifiers are industrial machines which are used to separate materials by size, shape, and density. By using forces - such as air drag, gravity and centrifugal force - they sort fine particles from coarse particles and lighter particles from heavier ones. While density does play a role, the air classifier separation process is mainlyget price
Keywords: static air classifier, classification efficiency, material density 1. Introduction In the pulverizing process of coal power plant, air classifier controls the fineness of Pulverized Fuel (PF). To ensure the qualified PF could react effectively with oxygen in the furnace, typically the coal particlesget price
Air classifiers separate materials based on shape, size, and density and are most commonly used in an industrial process involving mixed materials that need to be separated quickly. For example, in recycling centers, an air classifier can sort through metal, paper, and plastics that arrive mixed togetherget price
according to size or density. 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, when used in conjunction with grinding equipment, for increasing productivity. All three Sturtevant air classifiers offer durableget price
Nov 01, 2010 Air classifiers eliminate the blinding and breakage issues associated with screens. They work by balancing the physical principles of centrifugal force, drag force, collision and gravity to generate a high-precision method of classifying particles according to size and density. For dry materials of 100-mesh and smaller, air classification provides the most effective and efficient means forget price
Sep 10, 2017 γ – fluid density (combination of air and material density) A – cross section area of the particle va – air velocity. As can be seen, the centrifugal force is proportional to the square of the rotor rotational velocity and the air drag force is proportional to the square of the air flow velocityget price
Dec 01, 2012 While density does play a role in air classifier separation, the internal air currents are mostly affected by the overall mass and weight of the particles in the feed. Lighter and smaller particles are removed by the air flow, while heavier and larger particles are not entrained in the air flowget price
Oct 31, 2015 The density of a material is not the only characteristic of a particle that affects the air classification process. Moisture affects the separation as a result of its influence on the density of a material particle. Air classifiers may be one of a number of designs. The three principal groups of designs are horizontal, inclined, and verticalget price
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 material to be sorted up into the airget price

The Vortec C-1 Particle Classifier is the first classifier that can produce narrow particle bands with a maximum deviation of +/- 2 microns.The Vortec C-l Particle Classifier employs a unique tangential, centripetal air flow principle to obtain classification accuracy of +/- 2get price
pipe air classifiers is not satisfactory, since they are not able to achieve a density-dominant separation, zig-zag air classifiers and passive pulsing air classifiers became the designs of interest for study (Figure 1)2. Passive pulsing air classifiers have a cross-sectional area, which expands and contracts along the length of the deviceget price
These results suggest that passive pulsing air classification separates according to a different criterion than nonpulsing, and that particle density is the parameter. In studies with real particle separations, passive pulsing classifiers also outperformed nonpulsingget price
Air Classification. The Advanced Classification System (ACS) is a high efficiency air classifier first introduced in 1992 and granted a US Patent in November 1994. Air classifiers are used to separate dry fine powders based upon particle size, particle shape and also density. In general air classifiers can be used effectively in the range of 1mm to one micronget price

Gyrotor air classifiers, or rotating vane air classifiers, separate dry solid particles by size. They are designed for any separation where the fines are 500 microns (35 mesh) of finer. They can handle feed rates from 0.1 to 200 tons per hour depending upon the desired cut point and material densityget price
