my country's stone processing machinery industry has initially embarked on the road of modernization

　　The development of my country's stone processing machinery industry is the same as the main body of the stone industry, having experienced many ups and downs and years of exploration. After entering the 21st century, a preliminary modernized main industrial system with comprehensive development of scientific research, production, application, post-maintenance, and safety assurance has truly formed...

　　Before 1980, China's stone machinery industry was in its infancy. The national annual output of granite stone is only 30,000 square meters, and the annual output of marble slabs is 430,000 square meters, which is not as high as the current annual output of a large enterprise. At the same time, my country's stone processing machinery industry is also in the initial stage of development, and there are only more than ten enterprises in the country. In terms of stone processing machinery, it can only produce some conventional medium and small equipment, such as: small screw ten pendulum sand saws, hand-held rocker mills, medium and small diameter disc cutters, etc., and it is even more important in stone mining equipment. Laggard, in addition to the simple machines that are conventionally operated manually, the most advanced are several wire rope saws for marble mines imitating Italian equipment. These stone machinery and equipment are only used by some domestic small and medium-sized enterprises and have no export capacity.

　　 Afterwards, my country's stone industry experienced a major development. The number of stone enterprises rapidly increased to more than 10,000, and a large number of advanced foreign production equipment was introduced throughout the country. According to incomplete statistics, there are more than 200 processing lines for granite and marble alone, making my country's stone processing capacity reach 30 million square meters of slabs per year, and the annual mining capacity of mines is over 300,000 cubic meters. my country’s stone machinery enterprises have also made great progress. They have produced domestic granite and marble processing lines and diamond disc-type stone cutting machines with different switches and specifications. Domestic large-scale frame sawing machines are widely used in stone grinding equipment. From simple hand-held rocker mills to automatic mills of different specifications, most of the special-shaped processing machinery can be produced domestically.

　　Slowly, the number of stone enterprises nationwide has grown to 27,800. The annual production capacity of granite and marble slabs exceeds 100 million square meters. China's total stone output is already among the world's forefront, and China's stone imports into the mountain pass have reached 1.2 billion U.S. dollars. At the same time, my country's stone machinery industry has also reached a new level. More than 300 sets (sets) of stone mining and processing equipment and related technologies have been introduced across the country. my country's stone machinery, tool abrasives, and stone care industries have all developed rapidly.

According to incomplete statistics, there are more than 100 professional stone machinery and equipment processing enterprises in my country, some of which have been able to produce complete sets of large slabs, thin slabs, special-shaped slabs, tombstone processing equipment and mining equipment, and some companies have developed some advanced For numerical control processing equipment and engraving machines, some companies have been able to produce diamond abrasives and chemicals for various stone materials, and some companies can have further research and development capabilities. These domestically produced processing equipment, tools, abrasives, and chemical products are not only supplied to domestic enterprises, but part of them are also exported. The total output value of my country's stone machinery industry exceeded 3 billion yuan, and the export value of my country's stone machinery exceeded 10 million U.S. dollars during the same period.
