It is also the wish of everyone in the industry that the concrete mixer has no obstacles to production and operation and maintenance. Therefore, how to keep the concrete mixer in good condition at all times is the top priority of many engineering work. Since loading the mixer truck, some customers think that the concrete mixer can only be shut down after completion. In fact, this idea is wrong. In order to solve the hidden dangers of the concrete mixer in time and ensure that the concrete mixer is in good condition, it is necessary to maintain it well after shutdown so that there will be no frequent small problems. What should be paid attention to when using the concrete mixer after completion?

，自上料攪拌車，工作完成后應將散裝水泥罐閘門關好，將螺旋管內水泥全部輸送出來，不要殘留任何水泥在管內。同時完全清洗機械及現場。再者，對攪拌鼓內的混凝土一定要清洗干凈。對機械進行維護保養，對各潤滑點加注潤滑油，對需保護部分涂油防銹。

First of all, the gate of the bulk cement tank shall be closed after the work is completed, and all the cement in the spiral pipe shall be transported out without leaving any cement in the pipe. At the same time, completely clean the machinery and site. Moreover, the concrete in the mixing drum must be cleaned. Maintain the machinery, add lubricating oil to each lubricating point, and apply oil to the parts to be protected against rust.

自上料攪拌車，清掃攪拌站各部位漿液、積灰。及時清洗攪拌罐內及整機表面的灰塵、沾附的砼和油污，防止砼干結，保持清潔。生產結束后，停機前要及時完全清洗攪拌機內殘存的砼，停機后將所有操作開關置于斷路位置，并關閉各電源開關

Clean the slurry and ash in all parts of the mixing plant from the loading mixer. Timely clean the dust, concrete and oil stain in the mixing tank and on the surface of the whole machine to prevent the concrete from drying and keep it clean. After production, clean the remaining concrete in the mixer in time before shutdown. After shutdown, place all operation switches in the open position and turn off all power switches
