Aiming at the existent shortage of loading stab-powder for stab detonator at the present time interiorly, researches on automatic spoon-like powder-loading device, designed independently is made. The working of automatic loading for stab detonator with high sensitivity is introduced, and the pivotal technology about powder loading is analyzed. Corresponding measures are taken based on stab-power’s characteristic. The result shows that the technology can ensure the implement of automatic manufacture of this kind of sensitive powder, which reduces the operator scale, improves the security, quality and the efficiency of production.
