The main preparation method of high-strength high-chrome corundum is sintering method. The sintering method is to mix chromium ore, aluminum ore and other raw materials evenly, then sinter at high temperature, and then crush, screen and other processes to obtain high-strength high-chrome corundum.

[0003] In workshop production, corundum wear-resistant repair materials need to be removed from impurities and mixed, but the existing equipment only mixes them by stirring, and does not screen their particle size, resulting in high internal impurity content and uneven mixing, which seriously affects subsequent production. Utility Model Content
