Description

Technical Field

[0001] The utility model relates to the technical field of sampling instruments, in particular to a sampling instrument for measuring bulk density of powdered minerals. Background Art

[0002] Bulk density is the mass per unit volume of a material in a stacked state. In the field of non-ferrous metal mining production, it is often necessary to measure the bulk density of certain powdered materials.

[0003] A sampling device for measuring bulk density of powdered minerals is designed to improve the efficiency and accuracy of bulk density measurements in nonferrous metal mining operations, helping workers more easily obtain reliable data and reducing the errors and labor-intensive nature of manual operations. Its unique design enables efficient collection and precise measurement of powdered mineral samples, providing strong support for quality control and process optimization in mining operations.

[0004] In practical applications, sampling equipment for bulk density determination of powdered minerals usually requires the following technologies:

[0005] 1. Precise sampling mechanism to ensure that representative samples are obtained from powdered minerals; the sampling mechanism adopts advanced design, which can penetrate deep into the material and collect original samples according to the set method, avoiding only taking the surface or local uneven materials, and ensuring that the sample can truly reflect the characteristics of the entire batch of powdered minerals.

[0006] 2. A stable volume measurement device ensures that the volume of material collected each time is fixed and accurate; the volume measurement device has high precision and can effectively avoid density calculation deviation caused by volume error, providing a reliable data basis for subsequent density calculation.

[0007] 3. Convenient weighing system, convenient and quick to weigh the collected materials; the weighing system has high sensitivity and accuracy, can instantly and accurately display the material weight, reducing weighing time.

[0008] 4. Durable overall structure, adaptable to the harsh working environment of the mine. The whole device is made of strong and durable materials, which can resist the corrosion of powdered minerals, wear and tear and the loss caused by frequent use, ensuring long-term stable operation.

[0009] Currently, mining companies employ a variety of sampling methods to meet the demand for bulk density determination of powdered minerals. Some rely on manual sampling using simple tools, which is not only labor-intensive but also difficult to ensure randomness and accuracy. Others use simple, homemade sampling devices, but these devices have limited functionality and lack control over sample volume and sample uniformity. While more complex sampling equipment has improved sampling quality to some extent, it is complex to operate and expensive, making it unsuitable for widespread adoption.

[0010] However, in the above-mentioned method, the efficiency and reliability of the sampling device in actual use are poor, especially in the case of large-scale production and frequent measurement of bulk density. Problems such as high labor intensity, low sampling efficiency, and unreliable data have seriously affected the normal operation of mining production. In response to this problem, the present application proposes a solution and designs a sampling device specifically for measuring the bulk density of powdered minerals. By using this device, the shortcomings of existing sampling methods can be effectively solved, the efficiency of measurement and the reliability of data can be greatly improved, the labor intensity of staff can be reduced, and the actual demand for the measurement of bulk density of powdered minerals in non-ferrous metal mine production can be met.
