An attempt was also made to disperse the CNT in Mg alloy matrix by solid state friction stirring process for fabrication of metal matrix composite. Attrition milling was performed at a rotation speed of 700rpm for various times up to 6 hour. After 2 hours of milling, amorphous trace was ...
14. A new kind of attrition milling machine was introduced and it's working mechanism was discussed. 介绍了一种新型砂磨机的设备结构和砂磨机粉碎法的工作原理。 15. In this thesis, three major achievements were made in theoretical study: conditions and rules for preparing nano-powders by chemical...

Colloid Mill Product is fed into hopper and specially designed feeding device push the material to stator and rotor for high shearing, cutting and rubbing forces. Due to conical arrangement, the slightly deviating tapeiring of the milling surface of the stator and rotor, the angular gap becomes...
This invention relates to improvements in an attrition mill or disintegrator for reducing middling stock in flour mills to flour and particularly to reducing the finer middlings and flakes in their last reduction in the process of milling whereby a closer yield and softer, whiter flour is produced...

The nonconventional technique of attrition milling has been used to produce superconducting BSCCO powder from the starting powders of oxides and carbonates of Bi, Sr, Ca and Cu. This process shows a drastic reduction in processing time by 80% from the conventional solid-state reaction. The complet...
In this work, we report the first observation of mechanically driven amorphous-nanocrystalline-amorphous phase transformations in Se during ball milling. Complete nanocrystallization of a glassy Se sample and complete amorphization of a nanocrystalline Se sample were realized by mechanical attrition, which ...
