(1) Structure of concrete mixer

全自動自上料攪拌車是把水泥、砂石骨料和水混合并拌制成混凝土混合料的機械。主要由拌筒、加料和卸料機構、供水系統(tǒng)、原動機、傳動機構、機架和支承裝置等組成。目前，全自動自上料攪拌車被廣泛應用于工業(yè)和民用工程中，在攪拌站設備中，全自動自上料攪拌車更是起著不可替代的作用。

Concrete mixer is a machine that mixes cement, aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and discharging mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. At present, the concrete mixer is widely used in industrial and civil engineering, in the mixing plant equipment, the concrete mixer plays an irreplaceable role.

（2）全自動自上料攪拌車的不同分類

(2) Different classification of concrete mixer

·按作業(yè)方式分：循環(huán)作業(yè)式全自動自上料攪拌車、連續(xù)作業(yè)式全自動自上料攪拌車

·According to the operation mode: cycle operation concrete mixer, continuous operation concrete mixer

循環(huán)作業(yè)式攪供料、攪拌、卸料三道工序是按一定時間間隔周期進行的，即按份拌制。拌制的各種物料都經(jīng)過準確的稱量，故攪拌質量好。目前大多采用此類型作業(yè)方式。

The three processes of mixing, feeding, mixing and discharging are carried out periodically according to a certain time interval, i.e. mixing by parts. All kinds of materials are accurately weighed, so the mixing quality is good. At present, this type of operation is mostly used.

連續(xù)作業(yè)式上述三道工序是在一個較長筒體內(nèi)連續(xù)進行的，各料的配合比、攪拌時間難以控制，故攪拌質量差。目前使用較少。

Continuous operation the above three processes are carried out continuously in a long cylinder, and the mixing ratio and mixing time of each material are difficult to control, so the mixing quality is poor. At present, it is less used.

·按攪拌方式分：自落式全自動自上料攪拌車、強制式全自動自上料攪拌車

·According to mixing methods: self falling concrete mixer, forced concrete mixer

JZC500 )、JZC350、JZC250鵬飛建機的自落式攪拌機型號有：(自落式攪拌機，就是把混合料放在一個旋轉的攪拌筒內(nèi)，隨著攪拌筒的旋轉，筒內(nèi)的葉片把混合料提升到一定的高度，然后靠自重自由撒落下來。周而復始，直至拌勻。常用于拌制塑性和半塑性混凝土。

JZC500), JZC350 and JZC250 are popular models of self falling mixers in Pengfei Construction Machinery Co., Ltd.: (self falling mixers put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then scatter it freely by self weight. Repeat until well mixed. It is often used to mix plastic and semi-plastic concrete.

強制式攪拌機JDC500 、JDC350、JS4000、JS3000、JS2000、JS1500、JS1000、JS750、JS500鵬飛的強制式攪拌機型號有：（單臥軸強制式和雙臥軸強制式，其工作時攪拌筒不動，而由筒內(nèi)旋轉軸上均置的葉片強制攪拌。這種攪拌機拌制質量好，生產(chǎn)效率高，但動力消耗大，且葉片磨損快。一般適用于拌制干硬性混凝土。）

Forced mixer jdc500, jdc350, JS4000, JS3000, JS2000, JS1500, JS1000, js750, JS500 Pengfei hot-selling forced mixer models are: (single horizontal shaft forced type and double horizontal shaft forced type, the mixing drum does not move when it works, but forced mixing by blades on the rotating shaft in the drum. This kind of mixer has good mixing quality, high production efficiency, high power consumption and fast blade wear. It is generally suitable for mixing dry and hard concrete.)

·按裝置方式分：固定式攪拌機.移動式攪拌機

·According to the device mode: fixed mixer. Mobile mixer
