How can small automatic feeding mixer distinguish wet material mixer from dry material mixer? What's the difference between them?

小型混凝土搅拌机是从湿料式搅拌机和干料式搅拌机运送的混凝土含水量来区分的。目前在国内见到的大多数都是湿料式搅拌机，直接从自动上料搅拌机运送的预拌混凝土，商品混凝土，然后再运输的途中不断进行搅拌，以防混凝土凝结，离析。但是有一点湿料式混凝土从搅拌好运输中到工地浇筑，时间上不能超过1.5小时，这样的话如果是长距离的运输，混凝土肯定就废了，所以在这种长距离的情况下，一般采用干料式搅拌机或者半干料是混凝土搅拌机运送，在到达预定工地后再加水进行搅拌。

Small concrete mixers are distinguished by the moisture content of concrete transported by wet and dry mixers. At present, most of the wet material mixers are used in China. The ready mixed concrete and commercial concrete are transported directly from the automatic feeding mixer, and then they are continuously mixed on the way of transportation to prevent the concrete from setting and segregation. But there is a little bit of wet material concrete from the mixing transportation to the site pouring, the time can not exceed 1.5 hours, so if it is a long-distance transportation, the concrete will certainly be wasted, so in this long-distance situation, generally use the dry material mixer or semi-dry material is the concrete mixer transportation, after arriving at the scheduled site, then add water for mixing.
                       

干料式搅拌机可以按配比把石子，沙石，水泥按配比装入搅拌罐，然后在运输途中不断的对干料进行搅拌，运送到目的地，在加水混合。另外根据运送距离的长短，还可以采用半干料式搅拌机运送，半干料式搅拌机也是按比例将砂石，水泥混合，并且还含有一定量的水分，也是在到达目的地后再进行混合搅拌的。

The dry material mixer can load the stones, sand and cement into the mixing tank according to the proportion, and then continuously mix the dry materials during transportation, transport them to the destination, and mix them with water. In addition, according to the length of transportation distance, semi dry material mixer can also be used for transportation. Semi dry material mixer also mixes sand, stone and cement in proportion, and also contains a certain amount of water, which can be mixed after reaching the destination.

湿料式搅拌机和干料式搅拌机满足了不同要求的混凝土运输，给现代化建设带来了很大的方便。干料式自动上料搅拌机适合长距离的混凝土运输，当然还是要根据需求选择是湿料式还是干料式搅拌机运输混凝土的。

Wet material mixer and dry material mixer meet different requirements of concrete transportation, and bring great convenience to modernization. Dry type automatic feeding mixer is suitable for long-distance concrete transportation. Of course, wet type or dry type mixer should be selected according to the demand.
