The investigated phosphate grain mixture was mechanically activated by means of a Retsch ZM-1 ultra-centrifugal mill with a peripheral comminution path (Gemini BV, Netherlands). 1 The mill was supplied with high alloyed steel rotor with a 100 mm diameter. A number of rotor revolutions were adjusted at either 10,000 rpm or 20,000 rpm. By being ...

An Air Classifier Mill is used for milling and grinding heat-sensitive material and provides precise control over "particle cut point" selection, by incorporating an internal air-classifying wheel and an independent drive. Suitable for batch processing or continuous operation, the PPS Air Classifier range of Mills serve all industries that ...

Overview. The ADV is a bead mill with an integrated rotating part consisting of special rotor/separator. This type is an extremly low damage bead mill that pursues uniformity and low damage (low centrifugal force). The ADV realizes nano-particle dispersion, which a conventional bead mill has difficulties performing due to particulate fracture.

The ultracentrifugal disintegrator includes a device for cooling the annular zone (7), extending from the outer face (8) of the rotor (4) to the inner face (9) of the sieve (5), by feeding a...

the samples are homogenized and milled in a cutting mill to a particle size of <4 mm. Then, the sample size is reduced and milled in an ultracentrifugal mill equipped with a titanium rotor and screen to a particle size of <0.2 mm to obtain the analysis sample. 2.1.3. Determination of the Ash Content. The ash content is
