The mixing quality of concrete mixer is not only related to raw materials and equipment, but also closely related to the mixing time. The mixing time of concrete mixer directly affects the production efficiency and mixing quality of concrete. Setting too long stirring time will reduce production efficiency and waste time. If the mixing time is too short, it will lead to uneven mixing of concrete. So how long should the concrete mixer mixing time set more appropriate?

　　混凝土搅拌机的搅拌时间是指从完成装料到开始卸料的时间，可根据拌合物的坍落度和混凝土搅拌机的容量来确定。 影响混凝土搅拌时间的主要因素是混凝土的和易性、搅拌机的搅拌强度和强度、坍落度。

　　The mixing time of concrete mixer is to point to the time of beginning discharge from the completion of loading, can be based on the slump of mixed content and the capacity of concrete mixer to determine. The main factors affecting the mixing time of concrete are the workability of concrete, the mixing intensity and strength of mixer and the slump.

　　混凝土搅拌机的目的是将混凝土材料搅拌均匀。 强制式混凝土搅拌机是混凝土搅拌机中搅拌效率较高、搅拌质量较好的混凝土搅拌机之一。 不同的混凝土搅拌机工作原理不同，搅拌强度不同，搅拌时间也不同。

　　The purpose of a concrete mixer is to mix the concrete material evenly. The forced concrete mixer is one of the concrete mixer with higher mixing efficiency and better mixing quality. Different concrete mixers have different working principles, different mixing intensity and different mixing time.

　　一些小型混凝土搅拌机的搅拌时间为1-2分钟。 应使用“清洁浆法”混合约 3 分钟。 强制式混凝土搅拌机的搅拌时间较短。  JDC混凝土搅拌机的搅拌时间一般在30s左右。  JS混凝土搅拌机搅拌时间一般在60-70s左右。

　　Some small concrete mixers take 1-2 minutes. The mixture should be mixed for about 3 minutes using the "clean slurry method". The forced concrete mixer has a shorter mixing time. The mixing time of JDC concrete mixer is generally about 30s. JS concrete mixer mixing time is generally around 60-70s.

　　当然这只是正常的搅拌时间。 对于坍落度小的混凝土、外加剂和细砂，可根据实际情况适当延长搅拌时间。

　　Of course, this is just the normal mixing time. For the concrete with small slump, admixture and fine sand, the mixing time can be extended appropriately according to the actual situation.

　　混凝土中碎石、沙子等搅拌材料的含水量也在一定程度上影响混凝土搅拌机的搅拌时间。 夏季物料干燥，建议搅拌时间可以设置得长一些，物料有吸水过程。 该材料是湿的并且可能相对较短。 对于较长的混合时间，建议用户可以使用不同的混合时间进行试混合。http://www.zkhntjbj.com

　　The water content of gravel, sand and other mixing materials in concrete also affects the mixing time of concrete mixer to some extent. The material is dry in summer, it is suggested that the stirring time can be set longer, the material has a water absorption process. The material is wet and may be relatively short. For long mixing time, it is suggested that users can use different mixing time for trial mixing.
