由山东煤研所设计,辽源矿务局平岗煤矿截齿厂制造的PJ—8227型截齿,是专为薄煤层采煤机配套而研制的一种新型扁截齿。在这之前,我国薄煤层采煤机一直是沿用中厚煤层采煤机的截齿,这在一定程度上影响了薄煤层采煤机性能的充分发挥。该新型截齿对提高采煤机的落、装效率,降低采煤机功耗,增强机组工作时的平稳性,减少生产事故,降低截齿消耗量,节约钢材,降低吨煤成本等方面都具有积极意义。 Designed by Shandong Coal Research Institute, the PJ-8227 pick made by Pinggang Coal Mine Pick-up Factory of Liaoyuan Mining Bureau is a new type of flat pick designed for supporting the mining of thin coal seam. Prior to this, the thin coal seam shearer in our country has been used to pick coal shearer in the middle and thick seam, which to a certain extent, affected the full play of the performance of the thin seam coal winning machine. The new type of picks can improve the falling and loading efficiency of shearer, reduce the power consumption of shearer, enhance the stability of the unit during work, reduce the production accident, reduce the cutting tooth consumption, save steel and reduce the cost of ton coal Has a positive meaning.
