The clays are dried to a residual moisture content of < 1 and milled to various degrees of fineness down to < 40 µm. Powders can be delivered in loose form by tanker-lorry/truck or packed in big bags or sacks of filled weight
Chat Online· Air classifiers can separate powders as coarse as 80 mesh (180 microns μm ) and as fine as 2—3μm. The fineness of air- classified products is controlled by a precise balance between the quantity of rejector blades the speed at which rejector blades operate the velocity of the airflow and the rate at which the material is fed.

The mechanical action is submitting the particles to a stress under the stress some cracks will appear and subsequently the particle will be broken in different parts.

The internal air classifier holds material inside the mill chamber until it achieves the right fineness. Air jet mills use high levels of compressed air thus are expensive to run.

Chat OnlineMetal powders are finely divided base materials for metal-part production. The particle size of most metal powders varies from 5-200 µm 1 . Some common fabrication techniques that utilise metal powders are powder metallurgy additive manufacturing surface coating soft magnetic applications and metal injection moulding.
Chat OnlineFundamentally the term milling may be referred to as the breaking down of relatively coarse materials to the ultimate fineness. Apart from the milling of ores milling is also used for preparing materials for some industrial applications such as milling of quartz to fine powder (under 70 μm in diameter) milling of talc to produce body powder milling of iron ore for preparation of pellets and many others.

In na ideal size reduction process the particles from a homogeneous material would be of the same strength regardless of size. Therefore a plot of fineness atained versus work required to obtain that fineness would be a straight line.
