Preparations Of Composite Materials By Using Ball Mill Project report on Preparation and composite materials due to the very There are many types of grinding media suitable for use in a ball mill, each material. composite liner for mining grinding mills ag mill.
In order to obtain a new type of composite material rather than a simple mixture of uRDX and Al, the mechanical ballmilling technique, which could provide a powerful force to re ne mAl and generate the uRDX/Al composite, was applied. First, 2 kg of mm ZrO 2 was added as the milling medium in the cavity of a vertical ball mill.
In the chemical formula, a βSiC powder of g could be synthesized with the silicon powder of g and the carbon powder of remaining carbon powder of g (or mole) and the synthesized βSiC could be used to prepare a C p –SiC composite powder in the mill. The composite powder was rinsed with distilled water 5 times, and dried in a dryer at 80 °C (see Fig. 2(b)).
