从外观快速区分拌合机与冷再生机

　　Quickly distinguish between a mixer and a cold recycling machine based on their appearance

　　一、先确认设备类别

　　1、 Confirm the device category first

　　施工现场说的“拌合机”多指稳定土拌合机/路拌机（就地拌和灰土、二灰碎石、水稳层等）。

　　The term 'mixer' used on construction sites often refers to stabilized soil mixers/road mixers (for on-site mixing of lime soil, crushed stone, water stabilized layers, etc.).

　　“冷再生机”是另一类用于旧沥青路面就地铣刨并再生的专用设备，也可兼做稳定土现场拌和。两者用途不同，整机外观也有明显差异。

　　Cold recycling machine "is another type of specialized equipment used for on-site milling and recycling of old asphalt pavement, and can also be used for on-site mixing of stabilized soil. The two have different purposes, and there are also significant differences in the overall appearance of the machine.

　　二、核心外观差异一览

　　2、 List of core appearance differences

　　观察点拌合机（稳定土拌合机/路拌机）冷再生机

　　Observation point mixer (stabilized soil mixer/road mixer) cold recycling machine

　　工作装置明显看到转子+刀具；转子通常裸露或半裸露，位于机身中后部，作业时刀具高速切削、抛送物料同样有转子+刀具，但转子常深藏在壳体/铣刨鼓内，壳体前后有加料/出料口，刀具不外露

　　The working device clearly shows the rotor and cutting tool; The rotor is usually exposed or semi exposed, located in the middle and rear of the machine body. During high-speed cutting and material throwing, the tool also has a rotor and tool, but the rotor is often hidden deep inside the shell/milling drum. There are feeding/discharging ports in front and behind the shell, and the tool is not exposed

　　铣刨/切削动作可就地切削、破碎与拌和，刀具动作可见典型动作是先铣刨旧路面，再与新材料拌和；铣刨与拌和在同一工位连续完成

　　The milling/cutting action can perform on-site cutting, crushing, and mixing. The typical action of the cutting tool is to first mill the old road surface and then mix it with new materials; Milling and mixing are completed continuously at the same workstation

　　料流与开口多为开放式转子腔体，拌和后物料在后方或侧方形成条带，开口相对简单壳体前后设有加料口/出料口，再生料可直接落入摊铺机料斗，便于与摊铺工序衔接

　　The material flow and opening are mostly open rotor chambers. After mixing, the material forms a strip at the back or side. The opening is relatively simple, and there are feeding/discharging ports at the front and back of the shell. Recycled materials can directly fall into the hopper of the paver, making it easy to connect with the paving process

　　机身尺寸与底盘型号差异大，整体多为中等体量；常见为轮式或履带式底盘体量更大更“厚实”，整机质量常见在约19吨级；多为专用底盘，离地间隙、轴距等参数更大

　　The difference in body size and chassis model is significant, and the overall size is mostly medium; Commonly seen as wheeled or tracked chassis with larger and more "thick" body size, the overall weight of the machine is usually around 19 tons; Mostly for dedicated chassis, with larger parameters such as ground clearance and wheelbase

　　标识与涂装机身上常见“稳定土拌合机/路拌机”字样机身上常见“冷再生机/路面冷再生”字样，品牌如维特根、山推等

　　The common words on the identification and painting of the machine body are "stabilized soil mixer/road mixer", and the common words on the machine body are "cold recycling machine/road cold recycling". Brands such as Wittgen, Shantui, etc

　　现场配套常与压路机配合完成基层施工常与摊铺机+压路机联动，再生料直接输送至摊铺机料斗

　　On site support is often coordinated with rollers to complete grassroots construction, and is often linked with pavers and rollers. Recycled materials are directly transported to the hopper of the paver

　　以上差异点中：转子是否外露、是否有前后开口与加料/出料口、是否强调与摊铺机的联动，是最直观的区分线索。

　　Among the above differences, whether the rotor is exposed, whether there are front and rear openings and feeding/discharging ports, and whether the linkage with the paver is emphasized are the most intuitive distinguishing clues.

　　三、三步现场判断

　　3、 Three step on-site judgment

　　看转子与壳体：刀具外露、开放式转子腔体，多为拌合机；转子深藏在壳体、前后有加料/出料口，多为冷再生机。

　　Look at the rotor and shell: the cutting tool is exposed, the rotor cavity is open, and it is mostly a mixer; The rotor is hidden deep in the shell and has feeding/discharging ports at the front and rear, mostly used as a cold regeneration machine.

　　看料流走向：拌合机多为后方/侧方形成条带；冷再生机再生料可直接落入摊铺机料斗，工序衔接紧密。

　　Observe the direction of the material flow: the mixer is mostly in the rear/side to form a strip; The regenerated material from the cold recycling machine can directly fall into the hopper of the paver, and the process is closely connected.

　　看体量铭牌：整机质量约19吨级、底盘与离地间隙更大、参数表标注“冷拌再生/就地再生”的，多为冷再生机；铭牌写“稳定土拌合机/路拌机”的，多为拌合机。

　　Looking at the volume nameplate: the overall weight of the machine is about 19 tons, the gap between the chassis and the ground is larger, and the parameter table indicates "cold mixing regeneration/on-site regeneration", which are mostly cold regeneration machines; The nameplate that reads' Stable soil mixer/road mixer 'is mostly a mixer.

　　四、容易混淆的情况

　　4、 Easily confused situations

　　有些冷再生机兼具稳定土现场拌和功能，外观上会同时出现壳体开口与加料装置；此时优先看是否有铣刨鼓/加料—出料口—与摊铺机联动这一整套再生作业特征。

　　Some cold recycling machines have the function of stabilizing soil on-site mixing, and the appearance may have both shell openings and feeding devices; At this point, priority should be given to whether there is a complete set of regeneration operation features including milling drum/feeding - discharge port - linkage with the paver.

　　实验室用的小型沥青混合料拌合机是台式设备，带加热锅、控温、搅拌桨，与道路现场的两种大型机械完全不同，避免混淆。

　　The small asphalt mixture mixer used in the laboratory is a desktop equipment with a heating pot, temperature control, and mixing blade, which is completely different from the two large machinery on the road site to avoid confusion.
