Introduction To Stone Processing Machinery And Equipment

In the past decade, there has been significant progress in the research and development of stone machinery and equipment in China, with some individual machines reaching international advanced levels of performance automation. However, China has not yet produced high-end technology equipment. In terms of the automation level of the overall production line of stone enterprises, there is still a gap compared to foreign countries. Some production processes still rely on manual operation, which not only affects production efficiency, but also leads to unstable factors in the quality of finished products due to the low quality of employees. Even though most stone companies in Italy, a world stone powerhouse, use highly automated production lines, they still need personnel with certain stone knowledge and experience to master the processing parameters in order to produce top-notch stone products.
Many foreign stone mines, especially granite mines, have fully used diamond bead wire saws to mine blocks, and in the sawing processing of granite blocks, the multiline diamond bead wire saws have also been promoted. However, many stone companies in China still use old-fashioned frame saws. One significant advantage of it is its low sawing cost, but it has many drawbacks:
① The assembly cost is high, approximately four times that of a diamond bead wire saw;
② There are many operators, and at least two people are required to operate. More people need to work together when replacing the saw blade;
③ The cutting speed is slow, and the cutting speed of the old-fashioned frame saw is only 2cm/h. The cutting speed of the new frame is only 3.5-3.8 cm/h. However, the cutting speed of the diamond bead wire saw can reach up to 20cm/h, which may be increased to 30cm/h;

④ The surface of the board cut by the frame saw is relatively rough and has poor flatness, resulting in a low polishing speed of 100cm/min, while the surface of the board cut by the diamond bead wire saw is smoother and the polishing speed can reach up to 160 cm/min, thus reducing the polishing processing time;
⑤ Both energy and material consumption are relatively high;
⑥ The disposal of waste steel mortar and the dust in the workplace cause serious environmental pollution.
