In order to reach the best performances, a grinding mill must be enhanced by a high efficiency classifier separating the fine product (with the minimum amount of coarse material, for improved product quality) and the coarse material (with the minimum amount of fine product, for improved grinding efficiency and minimum mill power consumption).

Closed or open dry grinding. Gyrotors are intended to be integrated into a conventional closed or open dry grinding circuit. They also can be utilized in a classification only .

Rotating classifier pressure drop is lower than that of stationary classifiers. In addition, grinding zone pressure drop is lower with the rotating classifier because it does not recirculate as many fine particles back to the grinding zone as is the case with stationary classifiers. Even when higher throughput is required at the expense

Product Details. The most critical part of the grinding media for any Air Classifier Mill is the Classifier itself. Its shape, length and blade configuration directly influence the particle size distribution generated by the milling process.

Based on the insights about the air flow within the air classifier mill presented in the first part of the paper [1] the particle laden flow in the vicinity of the grinding pins and through the ...

PPS Air Classifier Mills PPS Air Classifier Mills for UltraFine and Controlled Particle Size Grinding. PPS Air Classifier Mills are high energy grinding mills with an integral classifier to produce ultrafine powders.

Grinding takes place between a peripheral grinding track and a grinding disc equipped with beaters. The impacted product particles are transported into the upper part of the machine by the classifier air which is supplied and then presented to the variablespeed classifier wheel.

OPTIONS • Costeffective air recirculation system as option, can operate without a filter. • The classification efficiency can be optimized by the use of a second classifier for the coarse product, with inlet for secondary air.
