对于混凝土搅拌机我们很熟悉，那是因为经常能够在路上或者是工地上看到它，同时也有很多的疑问，比如混凝土搅拌机为什么要一直转呢？下面我们分析一番。

　　We are very familiar with the concrete mixer, because we can often see it on the road or on the site, but also have a lot of questions, such as why does the concrete mixer keep turning? Let's analyze it.

　　混凝土搅拌机主要是由多轴的卡车来完成运输的，并且在运输过程中罐体还要始终保持不停的旋转。因为混凝土是由石头，砂子，水泥和水组成，如果运输过程中不转，并且不停的颠簸，石头就会下沉到最底下，砂子在中间，水泥和水在最上面，等运输到目的地就会出现结块的现象，也是我们常说的闷罐。因此，转动既可以防止混凝土凝固，又可防止混凝土分层，而且还可以让混凝土混合的更均匀。

　　Concrete mixers are transported by multi-axle trucks, which rotate continuously during transportation. Because concrete is made up of stone, sand, cement and water, if the transportation process does not turn, and kept bumping, the stone will sink to the bottom, sand in the middle, cement and water on the top, and so on to the destination will appear to agglomerate phenomenon, which is also what we often say stuffy pot. Therefore, rotation prevents the concrete from setting, prevents the concrete from stratifying, and allows the concrete to mix more evenly.

　　混凝土搅拌机在运输过程中，有时候也会出现各种故障或者长时间堵车等情况，这就会让混凝土凝固在罐体中，出现闷罐现象。那么为何宁愿倒掉也不能闷罐呢？出现这种情况后人们也想出了很多办法，有采用在罐体某个位置切一个洞，然后人工用风镐将里面的混凝土一点点的清理出来，再把开孔焊接封上。

　　Concrete mixer in the process of transportation, sometimes there will be a variety of failures or a long traffic jam, which will make concrete solidification in the tank, the phenomenon of stuffy tank. So why dump it instead of smother it? After this situation, people have come up with a lot of methods, including cutting a hole in a certain position of the tank, and then manually cleaning up the concrete inside with pneumatic picks a little bit, and then welding the holes sealed.

　　也有利用破壁机配合水钻打孔，这样能够减少粉尘和沙石飞溅，然后从出料口排出，这种方法效率也较高。还有就是利用热胀冷缩的方法，即便是罐内被堵住，但罐内还是会有空间，用油烧混凝土后迅速浇水冷却，混凝土会变脆，这样也更容易清理。清理闷罐的费用根据不同的地方和清理的方法，价格也都不一致，经过清理后的罐体或多或少都有损坏，使用寿命也将变短。

　　There are also the use of wall breaking machine with water drill drilling, so as to reduce dust and sand splashing, and then discharged from the discharge port, this method is also high efficiency. There is the use of heat expansion and cold contraction method, even if the tank is blocked, but there will be space in the tank, oil burning concrete after rapid watering cooling, concrete will become brittle, it is also easier to clean. The cost of cleaning the stuffy tank is not consistent according to different places and cleaning methods. After cleaning, the tank body is more or less damaged, and its service life will be shorter.

　　另外我们经常能够在各种报道中看到关于混凝土搅拌机的各种交通事故，也造成了很多的伤亡，其主要有这些原因，混凝土搅拌机的整个底盘都非常的高，驾驶员在操作过程中就会出现很多的盲区，特别是转弯的时候。还有就是混凝土搅拌机的速度都普遍较快，加上车身和载有很重的混凝土，制动距离就会变长等，都是造成事故多发的原因。

　　In addition, we can often see various traffic accidents about concrete mixers in various reports, which also caused a lot of casualties, mainly for these reasons. The whole chassis of concrete mixers is very high, and the driver will have a lot of blind spots in the process of operation, especially when turning. There is the concrete mixer speed is generally faster, coupled with the body and carrying a very heavy concrete, braking distance will become longer, etc., are the cause of accidents.

　　混凝土搅拌机为什么要一直转？都是有工作上的原因的，如上述所讲的那样，为了安全还是要尽可能的远离混凝土搅拌机，不要去凑近。更多内容就来网站www.zkhntjbj.com看看吧。
