一、 冷再生機械和路拌機的工作原理不同

1、 The working principles of cold recycling machinery and road mixer are different

　　冷再生機械是通過將已被拆除的舊路面碾碎后與一定比例的新拌料進行混合再鋪設在原位，被廣泛應用于公路路面的修補和改造。而路拌機則是用來將各種不同種類的原材料進行混合，生成適合公路工程的混合料，進而再將混合料鋪設在路面上。

Cold recycling machinery is widely used in the repair and renovation of highway pavements by crushing old road surfaces that have been demolished and mixing them with a certain proportion of fresh materials before laying them in situ. The road mixer is used to mix various types of raw materials, generate a mixture suitable for highway engineering, and then lay the mixture on the road surface.

　　二、 冷再生機械和路拌機的適用范圍有所不同

2、 The application scope of cold recycling machinery and road mixer is different

　　冷再生機械主要用于舊路面的再生和改造，適用于大面積的路面修補和整治。而路拌機則適用于各種不同種類、不同比例的配合料的混合，以滿足公路工程的不同需求。

Cold recycling machinery is mainly used for the regeneration and renovation of old road surfaces, and is suitable for large-scale road repair and renovation. The road mixer is suitable for mixing various types and proportions of mixtures to meet the different needs of highway engineering.

　　三、 使用方法也有所差異

3、 There are also differences in usage methods

　　冷再生機械操作相對簡單，主要是將舊路面碾碎后拌和后重新鋪設。而路拌機則需要經過先進的計量、攪拌和輸送工藝后完成混合，再進行鋪設。

The operation of cold recycling machinery is relatively simple, mainly by crushing the old road surface, mixing it, and then re laying it. The road mixer, on the other hand, needs to go through advanced metering, mixing, and conveying processes to complete mixing before laying.

　　四、 功能有所區別

4、 Different functions

　　冷再生機械主要是將舊路面破碎、混合再鋪設，而路拌機則可以根據需要進行多種材料的混合，如瀝青混凝土、水泥混凝土、碎石等。

Cold recycling machinery mainly crushes and mixes old road surfaces before laying, while road mixers can mix various materials as needed, such as asphalt concrete, cement concrete, crushed stone, etc.

　　綜上所述，冷再生機械和路拌機雖然都是公路施工中經常使用的機械設備，但是它們的工作原理、適用范圍、使用方法和功能均存在一定的差異。熟知這兩種機器的區別，能夠更好地選擇使用，提高公路建設的效率和質量。

In summary, although cold recycling machinery and road mixer are commonly used mechanical equipment in highway construction, there are certain differences in their working principles, scope of application, usage methods, and functions. Being familiar with the differences between these two types of machines can help to better choose and use them, improving the efficiency and quality of highway construction.
