The general design incorporates a vertical, two-stage, closed circuit grinding chamber combined with an interstage air classifier that's housed as one unit. The air classifying mill reduces the size of the material through impact with a high speed grinding rotor. A screen frame is precisely fitted around the grinding rotor.
The Pulvocron's unique horizontal design also simplifies cleaning and maintenance while reducing downtime. Complete Particle Size Control Adjustable operating conditions including tip speed, air flow, and classifier speed provides precise control over the resultant particle size, material temperature, and capacity.

rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …
The versatile ACM Air Classifier Mill is used for the fine and ultrafine impact milling, drying and classification of soft to medium-hard materials, including heat-sensitive products and those prone to sedimentation.
The air classifier mill process. An air classifier mill, also known as an air classifying mill, uses airflow to separate particles by size. The mill consists of a grinding chamber, a classifying wheel, and a fan. The raw material to be ground is fed into the grinding chamber, which is impacted by a high-speed rotor fitted with hammers or pins.
This study shows the performance of a currently running vertical roller coal mill (VRM) in an existing coal-fired power plant. In a power plant, the coal mill is the critical equipment, whose...

One such alternative source of protein is plant-based proteins ... (fibrous) hulls of pulses can be finely ground with the ZPS classifier mill for their final application (e.g. pet food, cookies and brownies). ... and multi-wheel classifiers for ultrafine separations. Superfine powders in the range d97 = 3 - 10 µm. With the NG design, fineness ...
Increased mill capacity can be achieved by upgrading an existing classifier or replacing a current one with a high-efficiency classifier, such as the BLVT. Capacity improvements can be expected in the 15% to 17% range. The superior design provides controlled and guided material flow right up to and through the classifier.
Coghill and deVaney (1938) also conducted experiments in a pilot plant ball mill closed circuited with a rake classifier over a wide range of circulating load ratios. They noted that, "It held true that the percentage of decrease in mill capacity was almost identical with the percentage of finished material in the composite feed.
The ultimate objective of the dynamic model will be the implementation in a control system. The required setpoints of the mill/classifier system are predicted to obtain the desired product quality at minimum energy use. Furthermore the model can be used for scale up and plant design.

Patented classifier design Classifier wheel ConVor® In the fines outlet housing, through which the milling air, classifier air and the fines leave the mill, the impact velocity has been reduced, so that wear and the formation of build-up have been largely eliminated. The gap between classifier wheel and the fines outlet is purged with gas.
The ball mill is for grinding 0-20mm to small powder. It works together with the spiral classifier, so the overflow slurry from the classifier is about 80% 200mesh powder. The oversize particle from the classifier will go back to the ball mill grinding again, to form a closed-loop.
