12, 13 pebbles are more commonly used raw materials. They are more commonly used in the construction industry and are also more popular in the market. If you want to produce 12, 13 stones for construction, it is critical to choose the appropriate crushing equipment. So, what equipment is needed? Let's first understand what is the difference between the 12 and 13 stones?
The main difference between the 12 and 13 stones is the diameter of the stones. 12 stones represent 10-20mm crushed stone, 13 stones represent 16-31.5mm crushed stone. There are many types of sandstone used in the construction industry. Specifications are more commonly used. Due to the different types of stones, hardness and other properties, when the stone processing is performed, different equipment is used, and the particle size of the finished product will also be different. Cone crusher and impact crusher are machines commonly used on the market to hit 12, 13 stones. What is the difference between impact crusher and cone crusher? How should we choose the crusher? Let's first understand the working principle of cone crusher and impact crusher:
Cone crusher: The cone crushing cone swings under the action of the eccentric sleeve, which drives the crushing wall to squeeze and crush the material between the wall and the mortar wall. According to the lamination theory, the material is affected by multiple directions. According to its own texture; it will be broken and polished to form stable stone particles. It will fall from the gap between the swing wall of the crushing wall and meet the discharge requirements. The remaining materials will continue to be crushed until they meet the requirements.
Impact crusher: Impact crusher uses impact energy to crush materials. When the impact crusher is working, driven by the motor, the rotor rotates at a high speed. When the material enters the area of the hammer, it strikes and breaks with the hammer on the rotor, and then is thrown to the counterattack device to be broken again, and then rebounds from the counter back liner. Re-crushing to the hammer action area, this process is repeated, the materials from large to small into the first, second, third, counterattack cavity and repeatedly crushed until the material is crushed to the required particle size, discharged from the discharge port, adjust the counterattack and The gap between the rotors can achieve the purpose of changing the material discharge particle size and material shape.
We should understand the difference between the materials applicable to the two crushers. The impact crusher is mainly suitable for stones with medium hardness, such as limestone, coal gangue, kaolin, etc. Cone crusher is mainly suitable for medium hardness stone, such as granite, basalt, iron ore, aluminum ore, copper ore, etc. In addition, we also need to know that the cone crusher and the impact crusher are commonly used in the second-stage crushing equipment. The so-called two-stage crushing is one-stage crushing that cannot be completed. Like if the original stone is too large, more than 100cm, our front end. The jaw crusher is required for coarse crushing. The jaw crusher is mainly used for primary crushing, the size of the inlet is large, the output particle size can be adjusted, the size of the discharge port can fully meet the requirements of 12, 13 stone production, the crushing cavity is deep and there is no dead zone, and the processing capacity Strong, of course, if the raw stone is less than 30cm, we can directly use the impact crusher or cone crusher to crush.
