The influence of air classifier wheel speed on pea protein enrichment was studied (Pelgrom et al. 2013) by increasing the wheel speeds from 5000 to 12,000 rpm that resulted in reducing the mean particle size diameters (D 50) of the fine fractions (from 8.8 to 4.8 μm) and coarse fractions (from 23.7 to 19.2 μm). The protein content of the fine ...

The separation mechanism in deflector wheel classifiers is essentially influenced by the ratio between the centrifugal force created by the rotating deflector wheel and the drag force of the sifter gas flowing through the wheel. Fig. 1 shows the mode of operation of a deflector wheel classifier exemplary for the lab scale classifier Alpine …

A higher feed load of 450 g caused a high level of impingement of particles on to the rotating classifier wheel, causing decreased classifier wheel efficiency, and this resulted in a less well-controlled micronization process. Thus, aspect ratio and pellips were sensitive to the changes in performance of the classifier wheel.

The CSM classifier mill combines a mechanical impact mill with an integrated dynamic air classifier. The grinding is performed between a peripheral grinding track and the rotating beater gear. Due to the integrated classifier wheel, grain sizes free of coarse particles can be achieved without the disadvantages of an external grinding and ...

The classifier wheel rejects particles which are too large, and they reach the bottom of the classifier as coarse material. An airlock discharges this material there. Superfine …

The deflector wheel classifier is a widely used device for the separation of fine powders in different industrial applications. The primary objective of the separation process is to achieve high-quality separation of fine powders characterized by a narrow particle size distribution and high separation sharpness. Theoretically, the reduction in …

Due to this, the new MikroCut MC, which is an impeller wheel classifier, was designed. It enables cut sizes even in the submicron range. The operative field of the MikroCut MC is shown in Fig. 1. Additionally, the operative field …

A classifying wheel for a centrifugal air classifier is designed to be protected from wear, which has an extension of a classifying wheel vane affecting a flow pattern disposed in a flow channel and in a direction of centripetal force, i.e. a direction of flow of the classifying air is opposite to the direction of centrifugal force. The classifying wheel has at least one …

The downside was the extremely short service life of the classifying wheel. The total contamination with iron compounds in the end product was as much as 100 ppm. During a trial period with the ATP-PRO classifying wheel lasting several months, it was possible to reduce the end particle size by approximately 15 % (d90 = 1.0 μm).

The main airflow enters the mill through the main air inlet underneath the grinding disc which rotates with tip speeds of 70 to 120 m/s. The grinding fineness is adjusted by the speed of the classifier wheel. Product of the desired particle size is drawn through the classifier, coarse material, is rejected for further size reduction.

Independent drives for the impact rotor and classifier wheel allow the system operator to independently adjust their rotational speeds, thereby optimizing drag and tip speed control in producing the desired particle size distribution.
