合理选购冷再生机，不仅关系到工程的建设质量和施工进度，而且还有利于发挥设备的配套能力和降低工程造价，使大家获得好效益。下面冷再生机租赁厂家就选购冷再生机根据多方面优势来辨别问题讲讲吧。

Reasonable purchase of cold regenerators not only relates to the construction quality and progress of the project, but also helps to give play to the supporting capacity of the equipment and reduce the project cost, so that everyone can obtain good benefits. Let's talk about the cold regenerator rental manufacturers' problems in selecting cold regenerators based on their advantages.

根据工程质量要求选择：

According to the project quality requirements:

1、若想获得均匀的压实密度，可选用轮胎式冷再生机。轮胎式冷再生机在碾压时不破坏土壤原有的粘度，各层土壤之间有良好的结合性能，加之前轮可摆动，故压实较为均匀，不会有虚假压实情况。

1. If you want to obtain uniform compaction density, you can choose tire type cold regenerator. The tire type cold recycling machine does not damage the original viscosity of the soil during rolling, and the soil of each layer has good bonding performance. In addition, the front wheel can swing, so the compaction is relatively uniform and there will be no false compaction.

2、若想使路面压实平整，可选用全驱动式冷再生机。对冷再生机压实能力要求不高的地区，可使用线压力较低而机动灵活的冷再生机。若要尽快达到压实效果，可选用大吨位的冷再生机，以缩短工期。

2. If you want to compact and level the road surface, you can choose the full drive cold recycling machine. In areas where the compaction capacity of the cold regenerator is not high, the cold regenerator with low line pressure and flexible can be used. In order to achieve the compaction effect as soon as possible, large tonnage cold regenerator can be selected to shorten the construction period.

根据铺层厚度选择：

According to the paving thickness:

1、在碾压沥青混凝土路面时，应根据混合料的摊铺厚度选择冷再生机的重量、振幅及振动频率。通常，在铺层厚度小于60mm的薄铺层上，好使用振幅为0.35-0.60mm的2-6t的小型振动式冷再生机，这样可避免出现堆料、起波和损坏骨料等现象；

1. When rolling the asphalt concrete pavement, the weight, amplitude and vibration frequency of the cold recycling machine shall be selected according to the paving thickness of the mixture. Generally, on the thin paving layer with the paving thickness less than 60mm, it is better to use a 2-6t small vibrating cold regenerator with the amplitude of 0.35-0.60mm, so as to avoid stacking, wave and damage of aggregates;

2、同时，为了防止沥青混合料过冷，应在摊铺之后紧跟着进行碾压。对于厚度大于100mm的厚铺层，应使用高振幅（可高达1.0mm）、6-10t的大中型振动式冷再生机。

2. Meanwhile, in order to prevent the asphalt mixture from being too cold, rolling shall be carried out immediately after paving. For thick pavements with thickness greater than 100mm, large and medium-sized vibrating cold regenerators with high amplitude (up to 1.0mm) and 6-10t shall be used.

根据被压物料的种类选择：

Select according to the type of pressed material:

1、对于岩石填方压实，应选用大吨位冷再生机，以便使大型块料发生位移；

1. For rock filling and compaction, large tonnage cold recycling machine shall be selected so as to displace large blocks;

2、对于粘土的压实，好使用凸块捣实式冷再生机；

2. For the compaction of clay, it is better to use the bump tamping cold recycling machine;

3、对于混合料的压实，好选择振动式冷再生机，以便使大小粒料掺和均匀；

3. For the compaction of the mixture, the vibrating cold regenerator shall be selected to make the mixture of large and small particles uniform;

4、深层压实宜采用重型振动冷再生机慢速碾压，浅层则应选用静力作用式冷再生机。

4. Heavy vibration cold regenerator shall be used for slow compaction in deep layer, and static cold regenerator shall be used for shallow layer.

实际上，除从工程实际需要和条件合理选择冷再生机外，还要从制造商的技术、制造水平、知名度、服务能力、配件供应等方面综合考虑，切忌只图便宜而给自己造成损失。您可以关注我们网站http://www.tclqgc.com咨询更多。

In fact, in addition to the reasonable selection of the cold regenerator according to the actual needs and conditions of the project, the manufacturer's technology, professional manufacturing level, brand awareness, service capacity, spare parts supply and other aspects should also be considered comprehensively, and it is forbidden to cause losses to the manufacturer only for the sake of cheapness.
