Factors affect automatic batching system of dry mortar production line
The production of full-automatic dry powder mortar production line is automatically completed by mechanical equipment, including material proportioning, which is also the operation of automatic proportioning mortar production line according to the order of the program in control cabinet. Therefore, the accuracy of automatic proportioning mortar production line itself will be very important here, so the accuracy of batching system should be checked when purchasing equipment. The key to the production line of the full-automatic proportioning dry powder mortar production line is the system of measuring ingredients. As long as the accurate measurement can make the mortar products meet the requirements of buildings. The metering and batching system is controlled by computer. The upper and lower material level meter is set on the material bin to control the start and stop of the feeding equipment.
How to gurantee accuraccy proportioning of raw materials for Automatic mixing dry powder mortar mix plant?
1. Make sure there are enough materials to supply the feeding equipment.
For feeding equipment, dry mixed mortar uses more and more material silos, and the interval between conveying and feeding materials is quite long. It is suitable for the closed screw feeder as the feeding equipment and the material with good activity characteristics. Generally, the standard larger screw feeder is used as the rapid main raw materials feeding; the smaller standard fine screw feeder is used as the fine powder additives feeding.
2. The working time, working mode and closing time-Factors affect automatic batching system of dry mortar production line
The working time, working mode and closing time in advance shall be determined during on-site commissioning. In order to ensure continuous and stable feeding, the rotating speed of the screw feeder need to be suitable, and the ratio of pitch to diameter should be less than or equal to 0.5mm. As a fine feeding fine screw feeder, it is better to add a set of reducer. When approaching the rated quantity, the speed will gradually slow down to stop. In this design scheme, the feeding accuracy can usually reach more than ± 0.3%. In order to ensure the production rhythm, the standard of screw feeder for rapid feeding should be larger, and the feeding ability should not be less than 130% of the rated quantity. Because of the pulsation of the discharge of the screw feeder, the material may collapse after the screw feeder stops, which may affect the accuracy of batching. A quick stop valve shall be set at the outlet of the screw feeder, and the stop valve shall be closed quickly when the screw feeder stops.
