① According to the requirements of water absorption, aluminum content, strength and other requirements;
②The mud strips for producing inert ceramic balls are produced by a filter press and a vacuum mechanism (during the period, the moisture should be ensured);
③Accurately cut the mud strip (the size of the mud strip is equivalent to the specification of the inert ceramic ball to be produced), and select the extrusion forming process to accurately form it;
④The semi-finished products are put into the kiln after entering the drying room or naturally dried in the shade;
⑤ High temperature sintering of semi-finished inert ceramic balls;
⑥ Screening and packaging of finished products.
Among them, the forming methods mainly include semi-isostatic pressing (dry bag method) forming, isostatic pressing forming and rolling forming. The firing kilns mainly include high temperature tunnel kilns and shuttle kilns.
