自動混凝土攪拌機的選擇主要有3種，即按工程量和工期要求選擇、按設計的混凝土種類選擇、按混凝土的組成特性和稠度方面選擇。下面來講講吧。

There are mainly three kinds of automatic concrete mixers, namely, they are selected according to the requirements of quantities and construction period, the types of concrete designed, and the composition characteristics and consistency of concrete. Now let's talk about it.

1、按工程量和工期要求選擇混凝土工程量大且工期長時，宜選用中型或大型固定式混凝土攪拌機或攪拌站。如混凝土工程量小且工期短時，宜選用中小型移動式攪拌機。

1. Medium or large fixed concrete mixers or mixing plants should be selected according to the requirements of quantities and construction period when the concrete quantities are large and the construction period is long. If the concrete quantity is small and the construction period is short, small and medium-sized mobile mixers should be selected.

2、按設計的混凝土種類選擇攪拌混凝土為塑性或半塑式時，宜選用自落式攪拌機。如攪拌混凝土為高強度、干硬性或為輕質混凝土時，宜選用強制式攪拌機。

2. When the mixing concrete is plastic or semi plastic according to the designed concrete type, the self dropping mixer should be selected. If the mixed concrete is of high strength, dry and hard or light weight, the forced mixer should be selected.

3、按混凝土的組成特性和稠度方面選擇如攪拌混凝土稠度小且骨料粒度大時，宜選用容量較大的自落式攪拌機。如攪拌稠度大而骨料粒度大的混凝土時，宜選用攪拌筒轉速較快的自落式攪拌機。如稠度大而骨料粒度小時，宜選用強制式攪拌機或中、小容量的錐形反轉出料的攪拌機。

3. The self dropping mixer with large capacity should be selected according to the composition characteristics and consistency of concrete. For example, when mixing concrete with large consistency and large aggregate particle size, it is better to choose the self falling mixer with fast mixing drum speed. If the consistency is large and the aggregate particle size is small, it is better to select forced mixer or mixer with medium or small capacity and conical reverse discharge.

混凝土攪拌機，包括通過軸與傳動機構連接的動力機構及由傳動機構帶動的滾筒，在滾筒筒體上裝圍繞滾筒筒體設置的齒圈，傳動軸上設置與齒圈嚙合的齒輪。結構簡單、合理，采用齒輪、齒圈嚙合后，可有效克服雨霧天氣時，托輪和攪拌機滾筒之間的打滑現象；采用的傳動機構又可進一步保證托輪和攪拌機滾筒之間的打滑現象。

The concrete mixer, including the power mechanism connected with the transmission mechanism through the shaft and the drum driven by the transmission mechanism, is equipped with a gear ring arranged around the drum barrel on the drum barrel, and the transmission shaft is equipped with a gear engaged with the gear ring. The structure is simple and reasonable. After the gear and gear ring are engaged, the skid between the supporting wheel and the mixer drum in rainy and foggy weather can be effectively overcome; The adopted transmission mechanism can further ensure the elimination of skidding between the supporting wheel and the mixer drum.

混凝土攪拌機是把水泥、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、原動機、傳動機構、機架和支承裝置等組成。更多相關事項就來我們網站http://www.gdfcx.net咨詢吧！

Concrete mixer is a machine that mixes cement, sand aggregate and water into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device.
