Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery, specifically to a dry grinding device suitable for alloy phases or alloy-containing materials. Background Technology

[0002] The statements in this section are merely to provide background information related to the technical solutions of this application to aid understanding, and do not necessarily constitute prior art for the technical solutions of this application.

[0003] In hydrometallurgical processes and chemical analysis, material particle size plays a crucial role in the depth of leaching and refining of valuable metals and the accuracy of analytical results. Therefore, materials must be ground to a specific particle size before pilot production or sample analysis. For brittle materials of varying hardness, dry grinding mills are used to finely grind the material for 1-3 minutes, typically resulting in a particle size of approximately 150-200 mesh, which generally meets the requirements for testing. However, after 2 hours of continuous operation, the temperature inside the grinding bowl rises significantly due to prolonged running, causing the finely ground material to clump together and accumulate. For alloy phase materials or materials containing alloy phases, due to their ductility, the grinding bowl of the dry grinding mill easily overheats. This overheating not only prevents the alloy phase or materials containing alloy phases from being ground to below 100 mesh but also easily forms sheet-like structures of varying sizes. This not only fails to meet the particle size requirements of subsequent processes but also damages the material's uniformity and even alters some of its properties, reducing the representativeness of the sample. At present, the only way to process this type of material with a certain degree of extensibility is to extend the intermittent working time and sieve and grind it multiple times after the mortar cools down. This operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] Figure 1 A cross-sectional schematic diagram of a dry grinding apparatus suitable for alloy phases or alloy-containing materials according to one embodiment is shown; Figure 2 A perspective view of a dry grinding apparatus suitable for alloy phases or alloy-containing materials according to one embodiment is shown. The dry grinding apparatus includes a vibratory motor (not shown) and a grinding bowl, the grinding bowl including a grinding bowl body 1, an upper grinding bowl cover 2, a lower grinding bowl cover 3, an internal grinding ring 4, a grinding ingot 5, a grinding bowl base 6, a first cooling zone 7-1, and a second cooling zone 7-2.

[0019] The lower pressure cap 3 of the grinding bowl is located above the grinding bowl body 1, and the upper pressure cap 2 of the grinding bowl is located above the lower pressure cap 3. The upper pressure cap 2 and the lower pressure cap 3 are connected by a threaded interface 8. A cavity is formed between the upper pressure cap 2 and the lower pressure cap 3, serving as the first cooling zone 7-1 for placing ice packs. The grinding inner ring 4 is disposed inside the grinding bowl body 1, and the grinding ingot 5 is disposed inside the grinding inner ring 4. The grinding bowl base 6 is located below the grinding bowl body 1, and the grinding bowl base 6 is connected to the grinding bowl body 1 by a threaded interface 8. A cavity is formed between the grinding bowl base 6 and the grinding bowl body 1, serving as the second cooling zone 7-2 for placing ice packs.

[0020] In one embodiment, the dry grinding apparatus suitable for alloy phases or alloy-containing materials further includes a temperature sensor. In one embodiment, the temperature sensor is respectively disposed within the first cooling zone 7-1 and the second cooling zone 7-2, for real-time monitoring of the temperature of the cooling zones, enabling timely replacement of ice packs when the temperature is too high, thus maintaining a stable grinding temperature environment. In another embodiment, the temperature sensor may be disposed near the grinding ring 4 or the grinding spindle 5 to monitor the operating temperature of the grinding ring 4 or the grinding spindle 5, thereby prompting for replacement of ice packs or suspension of operation when the temperature of the grinding ring 4 or the grinding spindle 5 is too high.

[0021] In one embodiment, the dry grinding apparatus suitable for alloy phases or alloy-containing materials further includes an automatic control system connected to the vibrating motor and the temperature sensor to automate the grinding process. For example, when the temperature sensor detects that the temperature of the cooling zone is too high, or when the operating temperature of the grinding ring 4 or the grinding ingot 5 is too high, the automatic control system can stop the operation of the vibrating motor.

[0022] In one embodiment, sealing gaskets are provided in the first cooling zone 7-1 and the second cooling zone 7-2 to ensure that the cooling zones maintain good sealing during the grinding process and prevent the generated condensate or water leaking out in case the ice pack breaks from seeping into the grinding area or other places.

[0024] Ice packs placed in the cooling area can be, for example, quick-freezing ice packs, biological ice packs, or water-filled ice packs. Ice packs can be reused multiple times; purchase only enough to replace them. The replacement frequency can be every 1-3 working days, depending on actual conditions. Increase the replacement frequency during hot summer months. The standard for ice pack replacement can be that the temperature of the grinding ring 4 and grinding disc 5 does not exceed room temperature.

[0025] Before grinding the material, rotate the lower cover 3 of the grinding bowl to open the first cooling zone 7-1, place a frozen ice pack, and rotate and tighten the lower cover 3 of the grinding bowl; rotate the base 6 of the grinding bowl to open the second cooling zone 7-2, place a frozen ice pack, and then rotate and tighten the base 6 of the grinding bowl. After confirming that the upper and lower cooling zones are tightly rotated, proceed with the regular grinding operation.
