Talc Powder Grinding Machine

From the mines, the talc ore will be first crushed for primary size reduction, then is delivered to the grinding units for fine grinding. The ore is washed and dried to eliminate any unwanted material adhering to it.

Thereafter, the ore is blended to achieve the exact desired properties and stored in feed silo for further processing. The blended ore is then ground to the desired particle size distribution. The talc powder is conveyed to bagging machines where it is packed and sent to the loading point.

SBM is world leading supplier and manufacturer of crushing, grinding and procesing equipment. We have been specialized in fine grinding technoloyg for several decades. We developed complete series of talc powder grinding machine for sale, such as ball mill, raymond mill, high pressure mill, vertical roller mill, hammer mill, ultrafine mill, trapezium mill etc. Our grinding plant is widely applied in various indutrial grinding applications, and produce high quality fine powders.

Talc Powder Processing Plant

A commercial talc was treated by planetary ball milling to evaluate the changes of the main physical and technological properties due to induced progressive mechanical stress. Firstly, a high orientation of talc platelets was obtained, secondly a progressive structural disorder of the talc and finally a re-aggregation of the particles during prolonged grinding was observed. Delamination during the initial and intermediate stages cannot be excluded.

Mechanical grinding reduced the particles size and increased the specific surface area leading to enhanced absorption and cation exchange capacity during the initial and intermediate stages of grinding. The reduced lightness and brightness for prolonged grinding were attributed to the agglomeration of the particles. The mechanical treatment does not induce significant amorphization, thus preserving the main properties of talc even after prolonged grinding.
