不同堆积密度材料自动连续失重式称量给料技术

Automatic Continuous Weight Loss Weighing and Feeding Technology for Different Bulk Density Materials

失重称是一种通过静态称重的方式实现高精度连续定量给料的自动称重设备,它能对粉末、颗粒、片状等干散物料进行可靠、精确和稳定的给料,减少物料的浪费和提高混合物的一致性。实际生产中,根据不同堆积密度材料物料性质,设计具有合理容积率的计量漏斗,减少补料次数,提高生产效率。在输送不同堆积密度的材料时,务必监视好失重称的运行频率,挑选能满足生产要求合适的螺杆进行给料工作。实际生产中,要求失重称的误差数据一般在0.8%以内,失重称电机频率在10~49Hz时的平均误差低于0.8%,该频率范围内运行的精度满足生产要求。

Lossless weighing is an automatic weighing device that achieves high-precision continuous dosing by means of static weighing.It can reliably,accurately,and steadily feed dry,bulk materials such as powders,granules,and flakes.Waste of material and increase the consistency of the mixture.In actual production,based on the material properties of different bulk density materials,a measuring funnel with a reasonable volume ratio is designed to reduce the number of feeds and improve production efficiency.When transporting materials that do not use bulk density,be sure to monitor the operating frequency of the weightless weighing and select the screw that can meet the production requirements to perform the feeding work.In actual production,the error data required for weight loss is generally within 0.8%,and the average error of weightlessness when the motor frequency is 10-49 Hz is less than 0.8%.The accuracy of the operation in this frequency range meets the production requirements.
