Application prospect of diamond grinding wheel in stone processing

The availability of natural stone materials used for construction and decoration is different for most countries with large storage of raw materials. Until now, many smaller stone producing countries have basically used for local consumption, but not export markets. In recent years, the global market has begun to change significantly

The mining volume of stone used for processing increased greatly. In 1998, the global mining volume was about 47.4 million tons, up 48% compared with 1997

In 1993, there were only three countries with more than 2 million tons of stone mining, Italy, Spain and China, with output of 7.5 million tons, 3.4 million tons and 2.5 million tons respectively. After five years, the number of such countries has increased to 7: Italy is leading by 7.5 million tons; China has risen to the second place with a production of 6million tons; Spain is in the third place with 4.5 million tons, India, the fourth largest producer, has 2.4 million tons. The other three countries that share the remaining 2 million tonnes are Brazil, Portugal and Greece

Figure 3 shows the share of these countries in global production, and Figure 4 shows the intercontinental distribution of global production.

Stone processing

In 1998, the total amount of stone processed by 14 major countries was similar to that of 1997, which was close to 15.2 million tons. The stone processing volume of these 14 major countries accounted for 71.5% of the world

In this group, its development has changed. Most countries have increased material processing volume, but as expected, the reduction in stone processing volume is reflected in the mining volume, and Japan, South Korea and Taiwan have shown a downward trend in processing

A clear global pattern is emerging in stone processing. Three countries control the world market, namely Italy, China and Spain. In 1998, these three countries accounted for the global natural stone processing volume (top 14 places) as shown in Figure 5:

The investigation in these areas shows that there are obvious differences in the methods and technologies used in Europe and China. The differences in culture, economic structure, foundation and technology lead to the development of industries which adopt different processing technology, equipment and tool design standards and different requirements for diamond performance in these tools
