1. Aggregate: coarse aggregate must be sampled and tested in accordance with regulations. Only qualified products can be used. Coarse aggregate shall be made of gravel or broken pebbles with reasonable gradation, good texture shape and uniform texture. The indexes of coarse aggregate shall meet the requirements of relevant standards and specifications; the mud content and mud content shall be controlled, and timely detection shall be conducted. If the inspection fails, it is forbidden to enter the unloading truck.

2.水泥：水泥必须按规定取样。进入每批的水泥需要及时进行标准稠度和温度测试。如果对质量有疑问，严禁进入仓库，继续测试其他指标。严格禁止合格水泥进入现场。严禁在工程中直接使用未加热的热水泥。

2. Cement: cement must be sampled as required. The standard consistency and temperature test shall be carried out in time for each batch of cement. If there is any doubt about the quality, it is forbidden to enter the warehouse and continue to test other indicators. Qualified cement is strictly prohibited from entering the site. It is forbidden to use unheated hot cement directly in the project.

3.矿物掺合料：按有关标准规范要求进行试验。实验室应及时了解矿物掺合料的质量变化。当矿物掺合料进入现场时，必须进行需水量，灼烧损失和细度测试。通过检验的产品可以存放;并注意初步测试。比较结果以确定质量波动并确保项目的质量。

3. Mineral admixtures: test according to relevant standards and specifications. The laboratory should know the quality change of mineral admixture in time. When mineral admixtures enter the site, water demand, ignition loss and fineness test must be carried out. The products that pass the inspection can be stored, and pay attention to the preliminary test. Compare the results to identify quality fluctuations and ensure the quality of the project.

4.外加剂：进入现场时应检查和测试外加剂。检查外加剂包装上是否标明以下内容：产品名称，型号，净含量或体积，制造商名称，生产日期和出厂编号。检查包装内标明的内容是否与产品规格和提供的证书一致由制造商;液体混合物是否沉淀出沉淀物并超过失效日期。

4. Admixtures: check and test admixtures when entering the site. Check whether the following contents are marked on the package of admixture: product name, model, net content or volume, manufacturer's name, production date and factory number. Check whether the contents indicated in the package are consistent with the product specification and the certificate provided by the manufacturer; whether the liquid mixture precipitates sediment and exceeds the expiration date.

其次，混凝土配合比应该是正确的。

Secondly, the concrete mix proportion should be correct.

第三，全自动水泥搅拌车的称重系统应准确。

Third, the weighing system of automatic cement mixer should be accurate.

影响全自动水泥搅拌车质量的因素很多。我们应该多加注意它。

There are many factors affecting the quality of automatic cement mixer. We should pay more attention to it.

应注意减少全自动水泥搅拌车部件的磨损

Attention should be paid to reduce the wear of the parts of the automatic cement mixer

1.维持全自动水泥搅拌车装置的额定负载

1. Maintain the rated load of the automatic cement mixer

这种工程机械负载的性质和尺寸对设备部件的损耗具有显着影响，并且如果部件负载高于设计，则一般机器部件磨损随着负载的增加而增加。随着工作负荷的增加，该部件的磨损继续增加。

The nature and size of the construction machinery load has a significant impact on the loss of equipment components, and if the component load is higher than the design, the wear of general machine parts increases with the increase of load. With the increase of working load, the wear of this part continues to increase.

2.按时清洁，以减少机器杂质对设备的影响

2. Clean on time to reduce the impact of machine impurities on the equipment

机械杂质通常指的是建筑机械本身在使用过程中产生的灰尘，污垢，其他材料以及一些金属废料和油脂污垢。当这些杂质到达机器的工作表面之间时危险增加。不仅摩擦力会增加，而且油耗也会增加。它还会破坏润滑膜并损坏配合表面。

Mechanical impurities usually refer to the dust, dirt, other materials and some metal waste and grease dirt produced in the process of using the construction machinery itself. The danger increases when these impurities reach between the working surfaces of the machine. Not only will the friction force increase, but also the fuel consumption. It also destroys the lubricating film and damages the mating surfaces.
