It can be seen from the name of concrete mixer truck that this kind of mechanical equipment is mainly used for concrete manufacturing and transportation. The mixing transportation of ready mixed concrete is mainly to transport the finished concrete mixed in the concrete mixing plant. During transportation, the rotation speed of the mixing drum must be well controlled at a low speed of about per minute. The blades in the mixing drum are used to continuously turn over and mix the concrete, so as to prevent segregation or hardening caused by static and ensure the quality of concrete transported to the site.

虽然增加了运输距离，可是这种距离和时间还是不能够过长，不能够超过混凝土的凝聚时间，其时间还是要受到混凝土的品质和环境等因素的制约。所以严格的说不同季节和时间下。其运输时间有所不同。

Although the transportation distance is increased, the distance and time can not be too long, and can not exceed the coagulation time of concrete. The time is still restricted by factors such as concrete quality and environment. So strictly speaking, in different seasons and times. The transportation time is different.

而对于拌合料的运输与预拌料则有所不同，拌合料不是成品混凝土，它是一种半成品。所以在运输途中搅拌筒的搅拌速度相对预拌料则要快许多，一般情况下根据混凝土拌合料的配制比例将速度控制在每分钟八到十转之间。

The transportation of mixture is different from that of ready mixed material. The mixture is not finished concrete, it is a semi-finished product. Therefore, the mixing speed of the mixing drum during transportation is much faster than that of the ready mixed material. Generally, the speed is controlled between 8 and 10 revolutions per minute according to the preparation proportion of the concrete mixture.

为了节省时间，对于拌合料也可以采用在运输途中进行搅拌成成品混凝土，这是就需要增加水箱等相应的装置,这种在运输过程中的搅拌可以增加不少的运输距离，延长混凝土凝结的时间，不乏是一种长途运输好的选择。

In order to save time, the mixture can also be mixed into finished concrete during transportation, which requires adding corresponding devices such as water tank. This kind of mixing during transportation can increase the transportation distance and prolong the concrete setting time. It is a good choice for long-distance transportation.

虽然为了增加运输距离和延长运输时间，采用拌合料运输途中搅拌成成品料，可以节约固定投资，提高相对生产率。但是这种方式的缺点也显而易见，难以获得质量好的成品混凝土，主要是受设备的限制不能得到均匀一致的混凝土。

Although in order to increase the transportation distance and prolong the transportation time, mixing the mixture into finished materials during transportation can save fixed investment and improve relative productivity. However, the disadvantages of this method are also obvious. It is difficult to obtain high-quality finished concrete, mainly due to the limitation of equipment.

对于要求严格的建设施工来说还是采用预拌混凝土的搅动运输比较好，所以我们大家大多数见到的都是预拌混凝土搅拌运输车。

For the construction with strict requirements, it is better to use the mixing transportation of ready mixed concrete, so most of us see ready mixed concrete mixing trucks.
