Comprehensive Guide To Quartz Sand Air Classifiers

Quartz sand air classifiers can be used as a single-sizing device in an open circuit

The air classification of manufactured sand (i.e., fine aggregates from crushed rock with a particle size smaller than about 4 mm) is used to separate crushed rock material into a fine particle fraction (filler, <100 μm) and a coarse particle fraction (>100 μm). Decreasing the filler content of the manufactured sand is merely crucial for the concrete industry to ensure the rheology of the cement paste. There is ongoing research for production methods that can be applied to create suitable manufactured sand. It is important because it fulfills the requirements set by ready-mix concrete producers.

Quartz sand air classifiers are masters of accuracy. They are a good option when the separation curve or cut point is too small for screens (200–400 mesh or finer) when the capacity is too large for screens (up to 800 ton/h) and when easy adjustability is needed to meet different product specifications.

One of the most important benefits of a classifier is its dry process. For dedusting aggregates, dry processing reduces the need for water or settling ponds, saving money and land, and doing good for the environment.

Air classifiers do not handle the more demanding work that pulverizers do and they function at much lower speeds. It means the equipment is less susceptible to wear and tear. With the addition of strong and protective liners, air classifiers can be used to economically process even abrasive powders including silica, fly ash, and ceramics.

Quartz sand air classifiers can separate powders as coarse as 80 mesh (180 μm), and as fine as 2–3 μm. An accurate balance among the quantity of rejector blades manages the fineness of air-classified products. It is the speed at which the rejector blades move. Also, the velocity of the airflow and the rate at which the material is fed. Even with fine powders, air classifiers rarely fracture or degrade particles because they do not function at pulverizer speeds and most of the feed never contacts the rotating parts.

Quartz sand air classifiers can be used as a single-sizing device in an open circuit where the feed is split into a fine discharge and a coarse discharge. This equipment can also be utilized in closed-circuit with mills. In this case, the use of the air classifier enhances the capacity of the mill and decreases the mill’s energy consumption because the mill does not have to serve as the sizing device.
