1. The square volume of automatic feeding mixer is generally not very large. At present, the automatic feeding mixer truck of each plant on the market has a maximum volume of 4 square meters of mixing tank, so it is more suitable for small and medium-sized projects.
2、磨损大。主要是自动上料搅拌车的搅拌罐与底部托盘磨损较大。因为作业频率高、作业强度大，自上料搅拌车的搅拌罐需要时时旋转，这就造成了搅拌罐与托盘之间的摩擦问题。
2. Large wear. The main reason is that the mixing tank and the bottom tray of the automatic feeding mixer are greatly worn. Because of the high operation frequency and high operation intensity, the mixing tank of the self loading mixer needs to rotate from time to time, which causes the friction problem between the mixing tank and the tray.
3、不能长距运输。自动上料搅拌车时速有限，只支持短距运输，不支持长距运输，如果自动上料搅拌车的两个项目之间距离很远，需要物流运输车将自动上料搅拌车运送下个项目处。
3. Long distance transportation is not allowed. The speed of the automatic loading mixer is limited and only supports short-distance transportation, not long-distance transportation. If the two projects of the automatic loading mixer are far away, the logistics transport vehicle is required to transport the automatic loading mixer to the next project.
总的来说，自上料搅拌车的优点是真的，缺点也是真的存在，但相对于方量不大、不支持长距运输这样较为普遍的弱势，搅拌罐磨损大、影响搅拌车寿命这点还是可以避免的，需要用户们选择正规大厂的搅拌车，就当下技术来讲，如鲁樽，在关于搅拌罐与托盘的磨损方面特研发出了拖轮摇摆技术，能使这两个部位“友好相处”，减小磨损，延长自上料搅拌车的使用寿命，这样的技术对自动上料搅拌车来讲是非常重要的。
Generally speaking, the advantages of self loading mixer are really excellent, and the disadvantages are also true. However, compared with the common disadvantages of small square volume and not supporting long-distance transportation, the large wear of mixing tank and affecting the service life of mixer can be avoided to the greatest extent. Users need to choose the mixer of regular large factories. In terms of current technology, such as Lu Zun, In terms of the wear of mixing tank and tray, tugboat swing technology is specially developed to make these two parts "get along well", reduce wear and prolong the service life of self loading mixer truck. Such technology is very important for automatic loading mixer truck.
说到底，自上料搅拌车打地坪效果怎么样，就是看生产的混凝土质量怎么样、效率怎么样、实用性强不强，当搅拌车满足了这些条件，项目效果自然呈现出来。
In the final analysis, the effect of self loading mixer on the floor depends on the quality, efficiency and practicability of the produced concrete. When the mixer meets these conditions, the project effect will naturally appear.
