The operator of concrete mixer shall receive the training and guidance from the manufacturer, have a full understanding of the structure and performance of the machine, and obtain certain operation and maintenance experience before operating the machine. The product operation manual provided by the manufacturer is the necessary information for the operator to operate the equipment. Before operating the machine, the operator must read the operation manual and operate and maintain the equipment according to the requirements of the manual.

　　注意混凝土攪拌機的工作負荷在磨合期,磨合期的工作負荷不應超過80%的額定工作載荷,并部署相應的工作量,以防止過熱造成的發生的連續操作機器很長一段時間。注意定期檢查各儀表的故障，出現異常時，應及時停機排除，在未找到原因、故障未排除前，應停止運行。還要注意不斷檢查潤滑油、液壓油、冷卻液、制動液和燃油(水)的液位和特性，并注意檢查整機的密封情況。檢查中發現油水過少，應分析原因。同時，應加強各潤滑點的潤滑，建議在磨合期間，每班向各潤滑點添加潤滑脂(特殊要求除外)。

　　Note that the working load of the concrete mixer is in the running in period, and the working load in the running in period shall not exceed 80% of the rated working load, and the corresponding workload shall be deployed to prevent the continuous operation of the machine caused by overheating for a long time. Pay attention to regularly check the faults of each instrument. In case of any abnormality, shut down the machine in time for troubleshooting. Before finding out the cause and troubleshooting, stop the operation. Pay attention to constantly check the liquid level and characteristics of lubricating oil, hydraulic oil, coolant, brake fluid and fuel (water), and check the sealing condition of the whole machine. In the inspection, it is found that there is too little oil and water, and the cause should be analyzed. At the same time, the lubrication of each lubricating point should be strengthened. It is recommended to add grease to each lubricating point in each shift during running in period (except for special requirements).

　　操作人員應堅持對混合器的各個設備進行清洗，并及時調整和擰緊松脫部分，防止松脫部分磨損或丟失。磨合期結束后，機器應強制停機，做好檢查和調整工作，并注意換油。

　　The operator shall insist on cleaning each equipment of the mixer, adjust and tighten the loose part in time to prevent the loose part from wearing or losing. After the running in period, the machine should be forced to stop, check and adjust, and pay attention to oil change.

　　攪拌器生產混凝土的原材料一般分水泥、粗、細骨料、水、外加劑等材料,材料的質量好壞直接影響混凝土生產的質量好壞,因為這不能粗心在材料的選擇上。對于水泥在攪拌機中應選擇當地大型廠家的正規產品，質量和數量，并測試混凝土凝結時間、穩定性、強度等重要指標。粗、細骨料選用優質砂石，砂石粒徑越大，混凝土強度越高，但價格自然也就越高。在保持強度的情況下，可以減少水泥和外加劑的用量。拌制混凝土使用的水也不能小看，雖然一般直接使用自來水，但也要檢查水的成分，因為各地水質不同，有些地方的自來水水質不宜隨著拌制混凝土的使用，需要非凡注重。后者是外加劑，外加劑的種類有磨細粉煤灰、磨細礦渣、磨細沸石和硅灰及其絡合物。為了保證攪拌外加劑的有效含量，應加強對液體外加劑濃度的檢測。

　　The raw materials for concrete production by agitator are generally divided into cement, coarse and fine aggregate, water, admixture and other materials. The quality of the materials directly affects the quality of concrete production, because it cannot be careless in the selection of materials. For the cement in the mixer, the regular products, quality and quantity of local large-scale manufacturers shall be selected, and important indexes such as setting time, stability and strength of concrete shall be tested. The coarse and fine aggregates are high-quality sand and stone. The larger the size of sand and stone, the higher the strength of concrete, but the higher the price is naturally. While maintaining the strength, the amount of cement and admixture can be reduced. The water used for mixing concrete should not be underestimated. Although tap water is generally used directly, the composition of water should also be checked. Because the water quality of different places is different, the tap water quality of some places should not be used with the mixing concrete, which needs special attention. The latter is an admixture, which includes ground fly ash, ground slag, ground zeolite, silica fume and their complexes. In order to ensure the effective content of the mixing admixture, it is necessary to strengthen the detection of the concentration of the liquid admixture.
