PROBLEM TO BE SOLVED: To provide a long-life receiving tooth for crushing sintered minerals by an internal chill brazing method by the combined effects of the prevention of the hardness lowering of a crushing part by water-cooling intensification by replacing use of receiving tooth action parts installed in the tooth, the improvement of water-cooling structure, and the prevention of slime and of the improvement of resistance to impact load destruction by the dispersion effect of heat/abrasion resistant pieces. SOLUTION: In the receiving tooth 10 of a single roll type hot crusher for crushing sintered minerals, receiving tooth action parts 11, 12, 13, 14 are fitted to the vertical and horizontal parts of the receiving tooth 10, and the action parts 11, 12, 13, 14 have a receiving tooth crushing part 15 in which heat/wear resistant pieces 20 are internal chill-brazed in wear-resistant cast iron, a water- cooling chamber 16 having water-cooling fins 18 of copper for cooling the part 15, and a magnet 17 which forms a local battery in a chamber 16 to prevent slime in the chamber 16.
