Polymer anti-stick lining plates

The conducted research and analysis of foreign experience showed that the most effective method of combating the adhesion of rocks to working surfaces is their lining with anti-adhesive and easily replaceable polymer plates. Thus, at the pelletizing plant of pelletizing factory of JSC Mikhailovsky GOK, as a result of the conducted research, the classification of polymer anti-stick lining plates (PASLP) was adopted, namely: PASLP HP (high pressure) SD (standard design); PASLP LP (low pressure) SD (standard design); PPFP IWR (increased wear resistance and impact resistance); PPFP HWR (high wear resistance and impact resistance). In the last 35 years, the following sheet materials have been recommended on the Russian market for various purposes: LDPE, HDPE, PP, PPFP-ASTIKI, PPL-EI, PPL-UI(CBM), Supralen1000, Tivar1000, VMPE 500, SVMPE1000, SVMPE9000, PE500, PE1000, PE9000, lnkulen 100, 500, 1000, 9000. For the correct selection of such materials for specific mining and geological and mining-technical conditions of operation of various process equipment, methods tested in the open press are recommended, allowing the selection of PASLP (sheets) depending on the strength of rocks according to the scale of prof. M.M. Protodyakonov and determining the optimal sheet thickness for various operating conditions of the equipment. Positive experience in combating the adhesion of finely ground iron ore concentrate and raw materials to the working surfaces of the process equipment of the pelletizing plant of JSC Mikhailovsky GOK named after A.V. Varichev is recommended for wide implementation at related enterprises of the Kursk Magnitka Anomaly, as well as at similar enterprises in other sectors of the mining and processing industry.
