PROBLEM TO BE SOLVED: To provide a kneader capable of kneading continuously and improving the precision of quality by mixing object materials efficiently. SOLUTION: The kneader comprises a mixer 21 mixing aggregate e.g. grit, crushed stone and/or gravel, earth and sand and/or sludge with a to-be-kneaded material comprising cement, water, etc. batch by batch, two or more weighing hoppers 38 storing a specified amount of aggregate to supply to the mixer 21 and a movable chute 39 charging aggregate selectively to two or more of the weighing hoppers 38. A belt feeder 33 for quantitative supply of aggregate to the weighing hoppers 38 is disposed in the upstream of the movable chute 39, and a weighing conveyer 37 capable of controlling the carrying rate is arranged between the belt feeder 33 and the movable chute 39, so that the carrying rate of the weighing conveyer 37 decreases when the amounts of aggregate in the weighing hoppers 38 approaches predetermined values.
