There are many types of concrete mixer, such as the continuous concrete mixer with short mixing time and high production efficiency, the drop mixer which is relatively convenient to use, and the disc mixer with rust prevention and wear resistance, simple structure, convenient operation and perfect function, etc. the preparation of equipment and the quality and hardness of materials will directly affect the concrete mixing The quality of the machine is described in detail below

一、混凝土搅拌机的类型

1、 Type of concrete mixer

1、连续式混凝土搅拌机：装有螺旋状搅拌叶片，各种材料分别按配合比经连续称量后送入搅拌机内，搅拌好的混凝土从卸料端连续向外卸出。这种搅拌机的搅拌时间短，生产率高、其发展引人注目。

1. Continuous concrete mixer: equipped with spiral mixing blades, various materials are continuously weighed according to the mix proportion and sent into the mixer. The mixed concrete is continuously discharged from the discharge end. This kind of mixer has the advantages of short mixing time, high productivity and remarkable development.

2、自落式搅拌机：流动性较好的混凝土拌合物可用自落式搅拌机，自落式搅拌机用起来更加方便，效率更高一点。

2. Self falling mixer: the concrete mixture with good fluidity can be used with self falling mixer, which is more convenient and more efficient.

3、强制式搅拌机搅拌：流动性较小或干硬性混凝土宜用强制式搅拌机搅拌。这种搅拌方式远比自落搅拌方式作用强烈，主要适于搅拌干硬性混凝土。

3. Forced mixer mixing: low fluidity or dry hard concrete should be mixed with forced mixer. This kind of mixing method is much stronger than the self falling mixing method, and is mainly suitable for mixing dry hard concrete.

4、盘式搅拌机：主要用于原料的混合的机械。该机采用聚丙烯板内衬或不锈钢板，具有不易粘料，耐磨损，采用摆线针轮减速机具有结构紧凑、操作方便、搅拌均匀、卸料输送方便等优点。

4. Disc mixer: mainly used for mixing raw materials. The machine is made of polypropylene plate lining or stainless steel plate, which is not easy to stick and wear-resistant. The cycloid pin wheel reducer has the advantages of compact structure, convenient operation, uniform mixing and convenient unloading and conveying.

5、塑性混凝土：是一种水泥用量较低，并掺加较多的膨润土、粘土等材料的大流动性混凝土，它具有低强度、低弹模和大应变等特性。

5. Plastic concrete: it is a kind of high fluidity concrete with low cement content and more bentonite, clay and other materials. It has the characteristics of low strength, low elastic modulus and large strain.

二、影响混凝土搅拌机质量因素

2、 Factors affecting the quality of concrete mixer

1、响混凝土搅拌机搅拌质量的主要因素是：搅拌机的结构形式，搅拌机的加料容量与拌筒几何容积的比率，混合料的加料程序和加料位置，搅拌叶片的配置和排列的几何角度，搅拌速度和叶片衬板的磨损状况等。

1. The main factors affecting the mixing quality of concrete mixer are: the structure of mixer, the ratio of the feeding capacity of mixer to the geometric volume of mixing drum, the feeding procedure and feeding position of mixture, the geometric angle of mixing blade configuration and arrangement, mixing speed and wear condition of blade liner.

2、确保混凝土的搅拌质量，要求混凝土混合料搅拌平均，搅拌时间短，卸料快，残留量少，耗能低和污染少。影响混凝土搅拌机搅拌质量的主要因素是：搅拌机的结构形式，搅拌机的加料容量与拌筒几何容积的比率，混合料的加料程序和加料位置，搅拌叶片的配置和排列的几何角度，搅拌速度和叶片衬板的磨损状况等。

2. To ensure the mixing quality of concrete, it is required that the concrete mixture should be mixed evenly, the mixing time should be short, the discharge should be fast, the residual amount should be small, the energy consumption and pollution should be low. The main factors affecting the mixing quality of concrete mixer are: the structure of the mixer, the ratio of the feeding capacity of the mixer to the geometric volume of the mixing drum, the feeding procedure and feeding position of the mixture, the geometric angle of the configuration and arrangement of the mixing blades, the mixing speed and the wear condition of the blade liner, etc.

3、混凝土搅拌机设备的性，要求能出产相互绿色型混凝土，与此同时，出产过程中的各种排放量和噪声等应符合划定的尺度。

3. The environmental protection of concrete mixer equipment, first of all, requires the production of green concrete. At the same time, all kinds of emissions and noise in the production process should meet the national standards.
