With the progress of science and technology, the development of concrete mixer production technology is very rapid. According to the different needs of concrete production and manufacturing technology, there are many kinds of concrete mixers. Among them, self falling mixer and forced mixer are two of them. As two different types of mixer, there are the following differences

强制式搅拌机又分为单卧轴强制式搅拌机和双卧轴强制式搅拌机。强制式搅拌机的搅拌量比自落式搅拌机的搅拌量大。自落式搅拌机主要是由机架，支撑轮，搅拌筒，曲梁，手柄，电动机等组成的。其中搅拌筒又是由圆锥体，圆柱体，Ｕ形体三部分组成。

Forced mixer is divided into single horizontal shaft forced mixer and double horizontal shaft forced mixer. The mixing capacity of forced mixer is larger than that of self falling mixer. The mixer is mainly composed of the mixer frame, the mixer frame, the self-supporting wheel, etc. The mixing drum is composed of cone, cylinder and U-shape.
自动混凝土搅拌机

混凝土管理设备包括混凝土筒仓、混凝土计量秤以及由变频器控制的配料螺旋。计量秤或雷达传感器用于测量筒仓中的物料量。为了避免产生大量粉尘，混凝土搅拌机还必须装有空气过滤器，利用振动原理自动去除空气中的粉尘。

The concrete batching equipment is controlled by frequency converter and concrete batching equipment. Weighing scales or radar sensors are used to measure the amount of material in the silo. In order to avoid a large amount of dust, the concrete mixer must also be equipped with an air filter, using the vibration principle to automatically remove the dust in the air.

此外使用传感器也能保护筒仓，避免仓内压力过大。混凝土搅拌机输送砂石控制。砂石在卸料斜槽中称重或在输送带上经应变式传感器测量。混凝土搅拌机水量测量，水量由带两个控制阀的计量秤称重，接着使用并联式流量计进行更精确的测量。辅料主要是使用泵和计量秤添加.

In addition, the use of sensors can also protect the silo from excessive pressure. Concrete mixer conveying sand control. The sand is weighed in the chute or measured by the strain sensor on the conveyor belt. The water quantity of concrete mixer is measured by a scale with two control valves, and then the parallel flow meter is used for more accurate measurement. Auxiliary materials are mainly added by pumps and scales

搅拌的混凝土骨料应严格筛选，zui大粒径不得超过允许值，以防卡料。

The mixed concrete aggregate should be strictly screened, and the large particle size of Zui should not exceed the allowable value to prevent material sticking.

每次搅拌时加入搅拌筒的物料，不应超过规定的进料容量，以免动力过载。搅拌叶片和搅拌筒底及侧壁的间隙，应经常检查是否符合规定要求。当间隙超过标准时，会使筒壁和筒底粘结的残料层过厚，增加清洗时困难并降低搅拌效率，如搅拌叶片磨损，应及时调整、修补或更换

The material added into the mixing drum during each mixing shall not exceed the specified feeding capacity to avoid power overload. The clearance between the mixing blade and the bottom and side wall of the mixing drum should be checked regularly to see if it meets the specified requirements. When the clearance exceeds the standard, the residual material layer bonded between the cylinder wall and the bottom will be too thick, which will increase the difficulty in cleaning and reduce the mixing efficiency. If the mixing blade is worn, it should be adjusted, repaired or replaced in time
