Stone Processing And Technology

The industrial chain of stone industry includes stone resource mining, geological exploration, mining, raw material transportation, etc., and some related fields need to involve petrology, etc.
According to the different processing technology, stone products can be divided into special-shaped products, such as carving, hollow column and solid column, and plate products include large plate and specification plate, and can also be divided into indoor and outdoor stones.
As for the processing of various stone products, the processing process of different products is also different, and the stone processing is also step by step.
Mine mining is the first step of all stone processing. Mining is also divided into manual mining and blasting mining. In addition, blasting mining is also divided into micro blasting mining and large blasting mining. In the coastal area, stone mining will use manual mining and micro blasting, because the local rock is soft, but in Sichuan, the local granite will be mined by large blasting, because its granite is hard, Generally, the use rate of mining stone by large blasting is relatively low, because it is broken in the explosion. Unless the stone is very hard, it will not be selected.
Sawing and processing waste materials. The large stones that have just been mined are called waste materials. Generally, diamond circular saws can be used to process stone slabs. If it is marble, it can also be processed with emery saws. The diamond circular saws use a kind of circular saw blade, which is inlaid with diamond particles adhered by powder metallurgy. This kind of processing equipment can process very hard stones, and it is also very flexible in use, The disadvantage is that the diameter of the disc needs to be twice the height of the stone plus the diameter of the flange plate, and the manufacturing of too large saw blades is very difficult, so it is not conducive to the processing of particularly large plates. The emery saw uses a row of strip saw blades, and each saw blade is like the manual saw blade used by carpenters, but the emery saw is multiple parallel, and the spacing between each saw blade is the same as the thickness of the plate, The emery saw can cut the whole piece of raw material into multiple pieces at one time. However, the emery saw is not suitable for processing granite with hard texture because it uses emery as abrasive. Generally, it is only suitable for processing marble and other soft stones. However, if there are defects in the raw material that are not found before processing, because the emery saw processing is completed at one time, it is too late to find defects after processing, This will lead to the scrapping of the whole piece of raw material and the waste of processing costs. Therefore, emery saw is not suitable for the raw material with many defects. This kind of processed stone is called rough board.
The cutting process is a very important step. The cutting process is to shape and cut the processed rough plate or polished plate. The main processing equipment is the longitudinal multi-saw blade cutter and the transverse cutter. The plate is cut by the cutter to the size we need, so that it can be sold out of the factory. We can make it into 300 * 600 and 600 * 900 conventional plates, It can also be processed according to the size required by consumers. After the above processes, it can be sold out of the factory
