Air Classifiers can be fed pneumatically and, in many cases, offers the opportunity to install the unit in a pneumatic conveying line. However, it should be noted that the particles in a pneumatic fed process enter the Air Classifier at much higher velocity than gravity fed particles.
Description. Our Air Classifier Mill offers fine grinding capability plus greater control over particle size distribution. Typically grinding to a particle size in the region of D97 = 10µm, our Air Classifier Mill serves all industries producing fine powders where control of grinding temperature and a narrow particle size distribution is of prime importance.

Obtain a full range of applicable fuel analyses as well as necessary drawings, dimensions and data on the boiler, burners, classifiers, coal conduits, mills, feeders and fans. Perform mill internal inspections, looking for wear, erosion, corrosion, inappropriate modifications, missing or broken parts, or non-functioning parts.
Prater's Air Classifying Mills operate by using the combination of two-stage closed circuit grinding/milling with an interstage air classifier all in one convenient unit. The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size.
Wei et al. calculated the air classifier efficiency in a ZGM coal mill by the fitting method, and its classification mechanism was revealed . With the help of numerical study, gas–solid properties, like flow path, particle motion, swirl velocity and so on, were demonstrated during classification process within air classifier.
classifier types To provide desired particle size distribution, Bradley mills can be equipped with different types of classifier, to meet customers' application demands. Static classifiers design is rugged and simple, without rotating parts and power consumption.
For use in a classifier cage of the type used in bowl mill coal pulverizers to direct a flow of coal fines and air into a classifier cone, the classifier cage having a circumferential inlet for receiving a flow of coal fines from a pulverizer throat, an improved classifier vane comprising:

For use in a classifier cage of the type used in bowl mill coal pulverizers to direct a flow of coal fines and air into a classifier cone, the classifier cage having a circumferential inlet for receiving a flow of coal fines from a pulverizer throat, a classifier vane comprising: a classifier vane adapted to be mounted in the ...
Efficient powder separator separation classifier after ball mill used in cement production line powder separators often work with ball mill, forming a closed- circle production plant. it's widely used for cement production, fly ash production, sand production and so on.
Dynamic classifiers: a fine way to help achieve lower emissions 8 April 2004 ... Hot air for drying the coal in the mill is provided by air heaters using exhaust gas discharged from the boiler to heat the incoming mill and combustion air. Each mill has an associated hot primary air fan to transport the coal from the mill to the furnace.
Williams High Efficiency Turbine Air Separators can help increase production rate from various grinding mills including vertical roller mills, ball mills, and others. These high efficiency air classifiers can achieve 80% efficiency while producing 70% minus 200 mesh (74 microns) and 70% efficiency when producing 95% minus 200 mesh (74 microns).
Ecutec produces an array of grinding technologies including ball mills, pin mills, jet mills and roller mills. Each type of mill has its own set of parameters and considerations, and Ecutec engineers have the expertise to recommend the right mill for each application.
An air classifier divides material flow into two parts. One of them consists of fine material, the other one of coarser parts. Centrifugal, gravitational and flow forces impact on mass elements which are of di"erent sizes and use natural laws to bring about classification.
