The present invention relates to a method for preparing a super absorbent polymer. More specifically, according to the present invention, by adjusting a stirring speed in a preparation step of a finepowder re-assembly during the preparation of a super absorbent polymer and separately adding water to fine powder, it is possible to operate a stable fine powder re-assembly preparation process whilemaintaining the assembly strength of a fine powder assembly, to reduce a re-pulverization ratio, and to prepare a super absorbent polymer having a high initial absorption rate. 提供了用于制备超吸收性聚合物的方法，并且更特别地，提供了这样的用于制备超吸收性聚合物的方法：其中其通过在用于制备细粉再组装体的过程中调节搅拌速度并将水分开添加至细粉中，可以稳定地操作用于制备细粉再组装体的过程，同时保持细粉再组装体的组装强度，其中可以降低再细化比率，并且超吸收性聚合物的初始吸收速度得到改善。
