The mixing quality of Zhongke concrete mixer is not only related to raw materials and equipment, but also closely related to mixing time. The mixing time of the concrete mixer refers to the time from the completion of loading to the start of unloading, which can be determined according to the slump of the mixer and the capacity of the concrete mixer. Make sure to mix evenly.

　　一般中小型混凝土攪拌機(jī)的攪拌時(shí)間為1-2分鐘，采用“清水漿包石法”攪拌約3分鐘。強(qiáng)制混凝土攪拌機(jī)的攪拌時(shí)間較短，如JD200混凝土攪拌機(jī)，只能使用30秒?？偠灾梢愿鶕?jù)施工的實(shí)際情況，通過試驗(yàn)來確定。坍落度小(機(jī)械搗固1-2cm，人工搗固2-4cm)、摻合料、細(xì)砂混凝土，可根據(jù)實(shí)際情況延長攪拌時(shí)間。

　　Generally, the mixing time of small and medium-sized concrete mixers is 1-2 minutes, and the mixing time is about 3 minutes by using the method of "water slurry and stone wrapping". The mixing time of the forced concrete mixer is short, such as jd200 concrete mixer, which can only be used for 30 seconds. In a word, it can be determined by test according to the actual situation of construction. Small slump (mechanical tamping 1-2cm, manual tamping 2-4cm), admixture, fine sand concrete, the mixing time can be extended according to the actual situation.
