Problems solved by technology

[0002] Synthetic diamond has a very broad market and an irreplaceable position as an alloy tool, drill or abrasive, but currently in the production of synthetic diamond, due to various factors in the production process, it is very easy to cause synthetically produced diamond products There are large differences in particle size, color, appearance and magnetic field characteristics, so it is necessary to screen synthetic diamond products many times, but now when screening synthetic diamonds, it is often necessary to use multiple screening machines And when each screening machine is working, its working parameters are also different, resulting in different screening results obtained by different screening machines, because at the same time in the operation, there is still a serious situation in which the working parameters of the screening machine are set randomly , It also leads to the different quality of synthetic diamond products obtained by the same screening machine at different working hours, which makes it difficult to achieve uniform quality of synthetic diamond products after screening. On the one hand, the quality of synthetic diamond products is greatly reduced. On the other hand, It also seriously affects the quality of products that always use synthetic diamonds as raw materials

Embodiment 1

[0013] Embodiment 1: a kind of synthetic diamond sorting process comprises the steps:

[0014] The first step is the primary selection of finished products. Place the finished diamond products that have been produced and prepared on the screening table of the screening machine. Five screening machines need to be used at the same time. The screening holes of the screening machines are 2025 mesh, 5045 mesh, and 7080 mesh. The screening frequency is 30 times / minute, 70 times / minute, and 100 times / minute, and the setting is fixed, and artificial adjustment is not allowed;

[0015] The second step is appearance screening. The finished diamond products that have been produced and prepared are placed on the screening table of the screening machine. It is necessary to use 15 screening machines to screen the three types of synthetic diamonds that have been pre-selected at the same time. The screening screen of the screening machine is 2025. Mesh, 5045 mesh, 7080 mesh three grades, the ...

[0018] Embodiment 2: a kind of synthetic diamond sorting process comprises the steps:

[0019] A kind of synthetic diamond sorting process, comprises the steps:

[0020] The first step is the primary selection of finished products. Place the finished diamond products that have been produced and prepared on the screening table of the screening machine. Five screening machines need to be used at the same time. The screening screens of the screening machines are 2025 mesh, 3055 mesh, 4550 mesh, 6070 mesh, There are five levels of 7080 mesh, the screening frequency is 30 times / minute, 50 times / minute, 100 times / minute, 150 times / minute, 180 times / minute, and the setting is fixed, and artificial adjustment is not allowed.

[0021] And the setting is fixed, no artificial adjustment is allowed;

[0022] The second step is appearance screening. The finished diamond products that have been produced and prepared are placed on the screening table of the screening machine. It is necessar...

Abstract

The invention discloses an artificially-synthesized diamond separation process. The process includes the finished product initial separation step, the appearance screening step, the magnetic screening step and the fine selection and packaging step. According to the artificially-synthesized diamond separation process, artificially-synthesized diamonds produced in the same batch or different batches and artificially-synthesized diamonds produced by different manufacturers can be strictly, uniformly, clearly and accurately classified in terms of the granularity, the color and luster, the appearance shape, the magnetic field characteristics and the like, and therefore quality of artificially-synthesized diamonds is improved, and the improvement of quality of devices with the artificially-synthesized diamonds serving as raw materials is facilitated.
