Now there are many bean curd dregs projects. This kind of project is not only the loss of property, but also the risk of life. The bean curd dregs project is due to the poor quality of concrete, so how should we control the quality of the automatic feeding mixer?

　　，混凝土配合比要保證混凝土有良好的工作性能，比如可泵性、大流動性、自密實性等。要滿足工程結構物強度、耐久性及其他特別設計要求。混凝土在配合比設計中要積極合理應用減水劑等混凝土外加劑，以減少混凝土用水量，降低水膠比，提高混凝土強度。在混凝土中適量摻加粉煤灰、礦粉等外摻料，取代部分水泥和部分細骨料，在保證混凝土強度等級與工作性能要求下，可以顯著提高混凝土的密實性，增加對鋼筋的保護作用，同時降低混凝土經濟成本。

　　First of all, the concrete mix proportion should ensure that the concrete has good working performance, such as pumpability, large fluidity, self compactness and so on. It shall meet the strength, durability and other special design requirements of engineering structures. In the mix design of concrete, concrete admixtures such as superplasticizer should be actively and reasonably applied to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete. In order to ensure the strength grade and working performance of the concrete, it can significantly improve the compactness of the concrete, increase the protection effect on the reinforcement, and reduce the economic cost of the concrete.

　　其次，原材料的管理要加強，砂、石料場要有良好的排水設施，以免底部積水。水泥、粉煤灰等粉料倉要有防潮、防雨措施。砂石料按品種、規格分隔堆放，避免混料。各種材料要標識清楚，特別是水泥、粉煤灰筒倉、外加劑貯存倉等進料口要加蓋標識，專人管理，以防止進錯料或受污染。

　　Secondly, the management of raw materials should be strengthened. Sand and stone yards should have good drainage facilities to avoid water accumulation at the bottom. Cement, fly ash and other powder silos shall be provided with moisture-proof and rainproof measures. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All kinds of materials shall be clearly identified, especially for the cement, fly ash silo, additive storage silo and other feeding ports, which shall be marked and managed by special personnel to prevent wrong feeding or pollution.

　　為了能夠加快施工進度、減少環境污染、改善施工條件、提高工程質量和節約材料成本。但是，全自動上料攪拌一體車的質量控制也是不可遺漏的要點。    
　　In order to speed up construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material costs. However, the quality control of the full-automatic feeding and mixing integrated vehicle is also an indispensable point.

　　自動上料攪拌機控制質量的方法就是上面這些，希望現在建的各大工程都能保質保量的完成。

　　This is the way to control the quality of the automatic feeding mixer. I hope that the major projects built now can be completed with quality and quantity guaranteed.

　　為自動上料攪拌機選擇的發動機一定要馬力足，因為它要帶動取力器、液壓油泵、減速機來進行攪拌罐的運作。另一方面還要提供給底盤動力，馬力不足是不行的。

　　The engine selected for the automatic feeding mixer must have sufficient horsepower, because it must drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, we need to provide power for the chassis. It's not enough horsepower.

　　變速箱，小型混凝土攪拌車選發動機馬力可以稍小一點，因為工作強度沒那么大，夠用就行，但是不能太小，太小買到手里一樣不省油、耽誤事。

　　The engine horsepower of gearbox and small-scale concrete mixer can be slightly lower, because the working intensity is not so large, it is enough, but it can't be too small, and it's not fuel-efficient and delays when buying too small.
