1 Main measurement and control content of mineral processing
The following describes the testing parameters of the main operation process of the concentrator.
2 Mineral flow detection
The detection methods of mine flow mainly include electronic type and nuclear type. These two flow detection instruments account for most of the existing ore flow detection instruments in China. The flow detection of ore is generally carried out on the transport belt. The instruments used to detect the ore flow mainly include electronic belt scales and nuclear belt scales.
Under the premise that the conditions of use can be met, the accuracy of the electronic belt scale is much higher than that of the nuclear belt scale. As far as installation and maintenance are concerned, nuclear belt scales have a clear advantage. For places where the measurement accuracy requirement is higher than 1.0, the nuclear belt scale should not be used. When the necessary conditions for the selection of the nuclear belt scale are not fully satisfied, the accuracy of the use of the nuclear belt scale can only reach 2.0 or worse. Before using the nuclear scale, the user must go to the relevant department to apply for a “nuclear product use licenseâ€.

3 Water flow detection
There are many types of water flow detection instruments and the most mature technology. Since the production water of the concentrator contains more or less muddy sand or other debris, the current water flow measuring instrument for beneficiation mainly uses electromagnetic flowmeter.
Principle: The electromagnetic flow sensor is based on Faraday's law of electromagnetic induction. When a liquid fluid or a liquid-solid two-phase fluid having a certain conductivity is used as a cutting magnetic field in a magnetic field, an induced electromotive force is generated in the conductive medium, and the magnitude of the induced electromotive force is detected to calculate the flow rate.

4 concentration detection
At present, for the detection of slurry concentration, the most used ones are nuclear density meters, and a small number of products such as heavy float concentration meters. Due to its convenient installation and maintenance, the nuclear density meter can realize non-contact detection and high detection precision. In recent years, it has been dominant in the detection of mineral concentration.
Using the detected concentration of the densitometer classification overflow, and thus indirectly detecting fineness, this method is widely used in metal ore beneficiation.
5 fineness detection
A meter that detects particle size is often referred to as a particle size analyzer. According to different test principles, it is divided into sedimentation particle size analyzer, sedimentation balance, laser particle size analyzer, optical particle counter, resistive particle counter, particle image analyzer and so on. At present, the most commonly used and applied effects are laser particle size analyzers and particle image analyzers.
A vibrating Screener, also known as a sifting machine or screening machine, is a device used to separate particles of different sizes by vibrating them through a mesh or perforated surface. The machine works by applying a high-frequency vibration to the material being screened, causing it to move along the surface and pass through the openings. The vibrating screener is commonly used in industries such as food processing, pharmaceuticals, and chemical manufacturing, where the precise separation of particles is critical. The machine is designed to handle large volumes of material efficiently, making it an essential tool for many manufacturing processes.
