The putty powder production line starts the feeding device according to the process batching sequence. First, the rapid feeding device will stop when feeding to the metering batching bin to approach the value (the specific value will be determined during debugging). The fine feeding device continues to feed and gradually approaches the batching amount. Considering the suspension amount, the fine feeding device gradually decelerates and stops in advance (determined during the adjustment of advance amount).
同时截止阀立刻关闭，截住可能出现的塌料。仪表随时跟踪下料量，精加料装置停止后，延时Δt秒，待静止后，仪表稳定的显示值，为种物料的工艺配料量。紧接着，第二种物料开始先快速向计量配料仓加料……重复上述程序直完成全部配料过程。考虑干粉砂浆生产线操作者的操作习惯和具体要求，也可手工点动精加料。
At the same time, the stop valve is closed immediately to stop the possible collapse. The meter will track the feeding amount at any time. After the fine feeding device stops, it will delay Δ T seconds. When it is still, the stable display value of the instrument is the process batching amount of the first material. Then, the second kind of material starts to quickly feed to the metering batching bin Repeat the above procedure until all batching processes are completed. Considering the operating habits and specific requirements of the operators of dry mortar production line, fine feeding can also be done manually.
计量配料仓的配料工作全部完成后，仓底的斜口密封阀门自动打开，计量配料仓的物料通过软联结和管道排入混合机。物料排空后，仪表回零，斜口密封阀门自动关闭。进入下一个配料循环。如果物料不能及时排空，斜口密封阀门则不能自动关闭。就不能进入下一个程序。此时，喷气嘴自动向斜下方喷气，将料排出。如果是柔性仓，则自动启动按摩装置，将料排出。
After the batching work of the metering batching bin is completed, the inclined sealing valve at the bottom of the bin is opened automatically, and the materials in the metering batching bin are discharged into the mixer through the soft coupling and pipeline. After the material is emptied, the instrument returns to zero, and the inclined seal valve closes automatically. Enter the next batching cycle. If the material can not be emptied in time, the inclined sealing valve can not be closed automatically. You can't go to the next program. At this time, the air jet nozzle automatically ejects air from the lower part of the slope to discharge the material. If it is a flexible bin, it will automatically start the massage device to discharge the material.
斜口密封阀门非常重要，可以实现全密封。如果仓底阀门密封不好，有泄露，不仅影响配料的准确性，而且现场粉尘太大，
The inclined seal valve is very important to achieve full sealing. If the valve at the bottom of the bin is not well sealed and there is leakage, it will not only affect the accuracy of batching, but also cause too much dust on site,
