Embodiment 2

[0061] Another specific embodiment of the present invention discloses a test method for evaluating the performance of a foaming agent based on a force sensor, using a test system for evaluating the performance of a foaming agent based on a force sensor in Example 1, and the steps include:

[0062] Step 1: Make a standard curve.

[0063] Place weights of different masses on the force sensor 32, record the change of the voltage signal generated by the test, and determine the corresponding linear relationship according to the measured voltage signal and the gravity of the weight, and make a corresponding standard curve;

[0064] Specifically, the force sensor 32 in this embodiment uses a bimorph as a cantilever beam to measure the force. The bimorph is a piezoelectric device, which exhibits a reversible piezoelectric effect. The material acts on an external force or an opposite external force. Under deformation, the internal charge is generated. When a force F is applied at the ...

Description

technical field [0001] The invention relates to the technical field of flotation reagent evaluation methods, in particular to a test system and method for evaluating the performance of a foaming agent based on a force sensor. Background technique [0002] Coal is one of the main energy sources in my country, and it is of great significance to the development of the national economy. Its status in my country's energy structure will not change for a long time in the future. With the improvement of coal mining mechanization and the maturity of lump coal dense medium separation technology, coal separation has the characteristics of micronization and high ash content, resulting in technical problems such as weak coal slime recovery ability and substandard quality. Difficulty sorting coal slime has become one of the common concerns of the industry and one of the problems that needs to be solved urgently. In recent years, the flotation process has increasingly highlighted its stro...
