  Last month, the first China International Abrasives grinding show was officially opened in Zhengzhou International Convention and Exhibition Center. The audience was in an endless stream and strong popularity. It was the first time in China's abrasive grinding industry to hold such an exhibition. It is seen that the industry has only appeared on a large scale this year, and it has not been paid much attention to before. Because of the decline in the cost of hard materials such as artificial diamond, it has led to the replacement of traditional abrasive, such as silicon carbide. It is this structural substitution that brought the diamond industry into the current cycle of development. Considering that the new applications of downstream are still emerging, the whole industry is on the rise. Low - end diamond products are now overcapacity: China's largest diamond production enterprises in South China have reached 4 billion 600 million carats, compared with last year's expansion of 1 billion carats. The third diamond producer is expected to exceed 1 billion 200 million carats this year. There will be a larger expansion plan announced in the future.

 
The exhibition found dozens of small and medium-sized enterprises with capacity under 500 million carats. The price of low end products has fallen from 0.30 yuan / carat to 0.20 yuan / carat, and the surplus of low-end products has begun to appear. We have visited the production enterprises of large press equipment in the field, and found that the equipment is completely domestically made, and the capital expenditure of expanding production is small. Therefore, the production of low end products should be said that there is no big barrier and the expansion of production capacity is easier. Low end products can be transformed into diamond powder and waste to treasure. According to experts, dozens of micropowder manufacturers were seen at the scene, and the industry concentration was lower than that of diamond. But we are delighted to find that the high-end product of micropowder is a high-tech barrier and a high value-added industry. For example, the special micro powder of diamond line has been found to be exported to the Japanese diamond line enterprises with the speed of 80~100 ten thousand carats per month. With the gradual application of the domestic diamond cutting line in the future, a broad market space will be ushered in the future, and the current export price can reach 3 yuan / carat. One of the most important applications of high end micro powder is to make PCD composite and make tools to replace traditional cemented carbide. The price of this kind of micro powder can reach 1~2 yuan / carat.
 
Even micro powder enterprises can produce nanocrystalline micro powder, and the price is as high as 10 yuan / carat. These high end products can be used to turn low end diamonds into valuable products, and at the same time alleviate the danger of low-end diamond overcapacity, which deserves attention. At the same time, the policy face is good: on the one hand, diamond related industries have been included in the development plan of new materials in 12th Five-Year, and the development of hard materials has led to the promotion of the whole industrial production level in China. On the other hand, Henan is a gathering place for the production of hard materials in China, and the formal approval of the Central Plains Economic Zone will enable the hard material industry of Henan to get more policy support. During the exhibition, the Minister of the Ministry of industry and commerce, who attended the approval activities of the Central Plains Economic Zone, gave high expectations to their development, such as airborne, diamond and other leading enterprises.
 
Experts say that the booming industry has brought better opportunities for the development of Yu diamond. Yu diamond low end products account for about 30%. Next year, all low-end products will be sold to Huajing micro powder (formerly Heng Xiang abrasives, Henan diamond Holdings 51%). Huajing fine powder will expand production next year with diamond micro powder to meet the production demand of Yu diamond diamond wire. Henan diamond has already completed the purchase of Chinese crystal powder at present. It is expected that the last two months of this year will be made. Next year, the fine powder will bring the performance contribution of the diamond and the supply of diamond line powder, and bring strong performance support.
