In order to upgrade the efficiency of proppants production, the OShGP 1 (Refractory fireclay granulated powders) size-grading sector was upgraded and the tube mill No. 6 of OShGP 2 (Refractory fireclay granulated powders) sector was put into service. The taken events allowed to produce more efficiently both common grading of proppants, and their desired cuts, and to increase the quantity and improve the quality of the output fine powders used for granulation.
The grading sector is fully automated, the process is coordinated by the operator using the control panel, and visualization system allows on-line control over the entire process of proppants grading. The products are packed in big bags by automated weighing-and-filling machines produced by LLC “VSELUG”.
In the current year the tube mill No. 6 will be further upgraded, in particular, the air separator produced by GEBR. PFEIFFER AG (Germany) will be installed. This will allow mill operation in the closed circuit.
