Conference > A.T.A.C. 2010

Industrie Bitossi partecipated to the conference about grinding process and grinding media for the ceramic industry organized by
A.T.A.C. (Asociación Técnica Argentina de Cerámica) in Buenos Aires - Argentina

on 19/05/2010

The presentation was given by Mrs. Giusy Baio Area Manager for the South America
"Discontinuous and wet grinding technology"

At the beginning of the speech,  the company Industrie Bitossi S.p.a and its products (Alubit Leonardo, Alubit Leonardo C, Alubit SQ) are introduced and particular relevance has been given to the innovative grinding media line "Alubit Leonardo"
The importance of the grinding technique to obtain a high-quality final product and to reduce the percentage of the second-rate final product is focused.
In addition to this, the speech highlights the importance of the usage of heterogeneous grinding charges, which are composed by both big diameters (useful in the first part of the grinding process to rough-shape the raw materials) and by smaller diameters that are useful to accelerate the refining process.
The abstract focuses also on the importance of the refilling grinding media, which have to be of different sizes, so to keep the efficacy of the speed grinding charges.
Other topics that are discussed: correct parameters of the grinding technique - Alubit-90 linings - Motor power - rotation speed - useful advice on the initial raw material particle size to be put  into the mill - advice on the composition of the grinding charge - final residue - grinding charge level - study of the pre-existent grinding conditions and  advice on the optimal conditions - Technique of the correct way to load  the mill with the grinding charge  - Standard grinding times, according to the type of the product to be ground - Evaluation of the probable causes of the alumina grinding media wear - Final summary tables.
