PROBLEM TO BE SOLVED: To provide a kneader, a mixer device, and a lorry which can easily prepare hydraulic mortar having a homogeneous moisture content.SOLUTION: A kneader 20 kneads a hydraulic composition and kneading water in a kneading chamber 21a to prepare hydraulic mortar. The kneader 20 includes a revolution number detection sensor 15, a calculation part 55b, and a display part 51. The revolution number detection sensor 15 detects the revolution number of a hopper screw 11 supplying the hydraulic composition to the kneading chamber 21a. The calculation part 55b calculates the supply amount of the kneading water supplied to the kneading chamber 21a based on the revolution number of the hopper screw 11 detected by the revolution number detection sensor 15. The display part 51 displays the supply amount of the kneading water calculated by the calculation part 55b. |
