Stone processing machinery and equipment

In the past ten years, the development of China's stone machinery and equipment has made great progress, and some single-machine performance automation has reached the international advanced level. However, China has not produced high-end technical equipment. In terms of the degree of automation of the overall production line of stone enterprises, there is still a gap compared with foreign countries. Some production links are still operated by manpower, which not only affects the production efficiency, but also causes unstable factors in the quality of finished products due to the low quality of employees. Even if most of the world's stone power companies in Italy use high-automatic production lines, they still need a certain amount of knowledge and experience of the stone to master the process parameters of the process to produce the top stone products.

package is standard and valuable,offering protection and safety of equipment.

Stone mining technology and equipment

There are still many stone mines in China that use the backward method of shooting and shooting to produce stone blocks. Not only is the production efficiency low and the operation is unsafe, especially the rock mass is broken due to knocking, and the stone resources are seriously damaged. The material size is irregular, even scrapped due to cracks, and the finished product rate is very low. It is estimated that only 5% to 8% of the mined material can be processed into materials by means of eye-blasting. In the early 1980s, some stone industry developed countries have banned the use of explosive blasting methods to mine stone, and replaced it with advanced technologies such as diamond bead wire saws. It can be said that this is a sign of the modernization of stone mining technology. An important indicator for measuring the modernization level of stone mining technology is: the number of cubic meters of per capita mined material. People in the international hall believe that China's stone mines have low productivity. The reason is the lack of mechanized equipment, backward mining technology and poor production management. The average annual mining volume of some stone mines is only a few hundred to several thousand cubic meters. The annual mining volume of a few stone mines is over 10,000 cubic meters, and the annual per capita output is 6 m3. The monthly per capita output is only 0.5 m3, which is lower than India. As everyone knows, India is also a big stone producer. However, its granite mines are small in scale and have no modern equipment, so the productivity of stone blocks is very low. The daily average is only 1 m3. Finland is the largest exporter of stone in Scandinavia. Its granite mine production system is world-class, with an annual export of at least 250,000 tons of granite, and the mine production efficiency is as high as 40 m3 per day. The productivity of South African stone mines is moderate, with a daily average of 8-10 m3.

Many stone mines abroad, especially granite mines, have used diamond bead wire saws to exploit blocks, and multi-line diamond bead wire saws have also been promoted in the sawing and processing of granite blocks. However, many stone companies in China still use old-fashioned frame saws. One of its significant advantages is the low cost of sawing, but there are many disadvantages:

1 assembly cost is high, about four times that of diamond bead wire saw;

2 There are many operators, at least two people need to operate. More people need to work together when changing the saw blade;

3 The sawing speed is slow, and the sawing speed of the old frame saw is only 2cm/h. The sawing speed of the new frame is only 3.5-3.8 cm/h. The cutting speed of the diamond bead wire saw is as high as 20cm/h, which may increase to 30cm/h.

The effect of diamond saw blades on stone

4The frame saw saws the surface of the plate to be rough and the flatness is also poor, so the polishing speed is low, 100cm/min, and the diamond bead wire saw saws the surface of the plate relatively smooth, and the polishing speed can be as high as 160 cm/min. , thus reducing the grinding and polishing processing time;

5 energy consumption and material consumption are relatively high;

6 Disposal of scrap mortar and dust at the work site cause serious environmental pollution.
