根据工程数量和工期要求进行选择
Select according to the project quantity and duration requirements
当混凝土工程量大、工期长时，宜选用中型或大型固定式混凝土搅拌机或搅拌站。如混凝土工程量小，工期短，宜选用中小型移动式拌和机。
When the concrete quantity is large and the construction period is long, medium or large fixed concrete mixer or mixing station should be selected. If the concrete quantity is small and the construction period is short, the medium and small mobile mixer should be selected.
根据具体设计选型
Type selection according to specific design
当混凝土为塑性或半塑性时，宜选用自降式搅拌机。其结构简单，维修方便，相对于强制式，搅拌效果稍差。如搅拌混凝土为高强、硬或轻混凝土时，宜选用强制搅拌机。其结构比较复杂，维修要求高，但混合效果好，效率高。
When the concrete is plastic or semi plastic, the self dropping mixer should be selected. Compared with the forced type, the mixing effect is a little worse. If the mixing concrete is high-strength, hard or light concrete, the forced mixer should be selected. Its structure is more complex and maintenance requirements are high, but the mixing effect is good and the efficiency is high.
根据具体的组成特点和一致性
According to specific composition characteristics and consistency
当搅拌混凝土稠度较低，骨料粒径较大时，宜选用大容量自降式搅拌机。如果混合稠度大，骨料尺寸大，建议选择速度较快的搅拌机。如果稠度大，骨料粒径小，或主要用于轻骨料或硬骨料混凝土的搅拌，建议选择强制搅拌机。一般高强度等级，对混凝土状态要求高、用量大，需要用强制搅拌。
When the consistency of mixing concrete is low and the aggregate size is large, a large capacity self dropping mixer should be selected. If the mixing consistency is large and the aggregate size is large, it is recommended to select a mixer with faster speed. If the consistency is large and the aggregate size is small, or it is mainly used for mixing light or hard aggregate concrete, it is recommended to select the forced mixer. Generally, the high strength grade requires high concrete state and large amount, so forced mixing is needed.
如果选择合适的搅拌机，并在使用过程中做好以下工作，将会大大提高搅拌机的工作效率:
If a suitable mixer is selected and the following works are done well in the use process, the working efficiency of the mixer will be greatly improved:
良好的润滑
Good lubrication
混凝土搅拌机每天工作前应检查各润滑部位的油、回路及控制设备，并按要求注满润滑油。但是，当地有很多需要润滑的润滑油，润滑的方法和数量都不一样，有时需要更换新的润滑油。
Before working every day, the concrete mixer shall check the oil, circuit and control equipment of each lubricating part, and fill the lubricating oil as required. However, there are a lot of local lubricants that need to be lubricated. The method and quantity of lubrication are different. Sometimes, new lubricants need to be replaced.
清洁工作做得好吗
Is the cleaning done well
混凝土搅拌机必须保证混凝土搅拌机的清洁，搅拌机内的污垢和障碍物，特别是搅拌机叶片或混凝土搅拌机侧叶片与罐体内壁之间的异物。
The concrete mixer must ensure the cleanness of the concrete mixer and remove the dirt and obstacles in the mixer, especially the foreign matters between the mixer blade or the side blade of the concrete mixer and the inner wall of the tank.
做检验工作
Do inspection work
(1)日常工作前必须检查传动离合器和制动器是否灵活可靠，钢丝绳是否损坏，轨道滑轮是否良好，四周无障碍，各部分润滑;
(1) Before daily work, it is necessary to check whether the transmission clutch and brake are flexible and reliable, whether the steel wire rope is damaged, whether the track pulley is in good condition, there are no obstacles around, and all parts are lubricated;
(2)混合器必须实施二次漏电保护，工作前电源接通后，必须仔细检查，试验后的空车确认合格，方可使用;
(2) The mixer must be provided with secondary leakage protection. After the power supply is connected before work, it must be checked carefully. After the test, it can be used only after the empty car is confirmed to be qualified;
每天混凝土搅拌机工作前，在搅拌缸内加水1 - 2秒，并检查离合器和刹车装置的可靠性。
Every day before the concrete mixer works, add water to the mixing cylinder for 1 - 2 seconds, and check the reliability of the clutch and brake device.
