目前大多数选矿厂使用的人工称重干燥测定水分的方法不能及时、准确地提供自动控制所需的信息。与精矿运输和处置有关的费用仍然是整个处理成本中的主要部分。由于选矿厂现金流量受冶炼厂的合同 (其中包括装船运输的精矿水分罚款 ,以及精矿数量和质量 )制约 ,一种高效的在线水分检测法将是非常受欢迎的工具。一种新颖的精矿水分在线检测系统将取代令人厌烦的人工方法。由于引进了基于微电子的控制系统 ,操作者已经将处理成本降低到最小。因此 ,有代表性的精矿水分的及时测定对于设定的控制点和信号的及时反馈是至关重要的。由于你只能控制那些你能测量的参数 ,因此可靠的传感器早就进入了选矿工作者的“希望名单”中。时至今日 ,水分测定仍然利用非控制的传统的失重法进行。这些方法最早引进到贱金属选矿厂中。一般可接受的精矿水分范围是 7%～ 9% ,但是人工控制 8%以下的水分在是很困难的。大多数情况下 ,在采取校正措施前 ,人工能达到的可靠的精矿水分范围在 5 %～ 12 %间变化。本文首先评述了利用物理原理和粒状物料的性质在水分测定中广泛使用的传统方法 ,并介绍了影响精矿水分测定方法的因素。叙述了一种新颖的在线水分传感器在选矿脱水作业中的应用 ,不仅使单调的工作实现了自动化 ,而且得到了可?
At present, the method of manually weighing and measuring the moisture used by most concentrators can not provide timely and accurate information needed for automatic control. The costs associated with concentrates transport and disposal remain the major part of the overall processing costs. Due to the smelter’s cash flows being governed by the smelter’s contract, which includes fine-grain moisture for shipment by ship, and the quantity and quality of concentrates, an efficient on-line moisture detection method would be a very welcome tool. A novel on-line concentrate system for concentrate moisture will replace the annoying manual method. With the introduction of microelectronic-based control systems, operators have reduced the processing costs to a minimum. Therefore, the timely determination of the representative concentrate moisture is crucial for the timely feedback of the set control points and signals. Since you can only control those parameters that you can measure, reliable sensors have long been in the hope list of miners. To date, moisture measurements are still carried out using uncontrolled, traditional weight loss methods. These methods were first introduced to the base metal concentrator. Generally accepted concentrate moisture range is 7% ~ 9%, but artificial control of water below 8% is very difficult. In most cases, the range of reliable concentrates that can be reached is between 5% and 12% before corrective action is taken. This paper firstly reviews the traditional methods widely used in the determination of moisture by physical principles and the properties of granular materials, and introduces the factors affecting the determination of concentrate moisture. Describes the application of a novel online moisture sensor in mineral processing and dehydration operation, which not only makes the monotonous work automation, but also achieves?
