1. The relevant information was provided by OPP mining machinery. Because of the limitation of space, no compensation for low-level work-related injuries and space, I removed the content of Grade 10 rating. Instrial injury level identification standard is labor ability identification, which refers to the level identification of the degree of labor dysfunction and self-care disorder. Labor dysfunction can be divided into ten disability levels, the heaviest is level 1, and the lightest is level 10. There are three levels of self-care disorder: totally unable to take care of themselves, most unable to take care of themselves and some unable to take care of themselves.

About the working principle of cone crusher and the role of each part, we summarized the main situation as follows, hoping to help you:

I. working principle of cone crusher

in the working process of cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of eccentric sleeve, The section of the moving cone near the static cone becomes the crushing cavity, and the material is crushed by the repeated extrusion and impact of the moving cone and the static cone. When the moving cone leaves the section, the material which has been broken to the required size falls under its own gravity and is discharged from the bottom of the cone

Second, the role of different parts of the cone crusher

the moving cone and the fixed cone cooperate with each other to achieve the crushing of materials, and the hydraulic system is used to adjust the size of the ore outlet of the crusher, and the hydraulic system can effectively ensure the safe operation of the equipment. When there is a foreign matter in the crushing cavity, the hydraulic system can make the moving cone fall back automatically. When the foreign matter is discharged, the system can make the falling moving cone reset automatically

this paper mainly introces the working principle of cone crusher and its role in the reproction of different parts. We mainly analyze the role of moving cone, fixed cone and hydraulic system. For other questions about cone crusher, please consult:// www.shibangchina.com Hope to help you

8. The above is the technical parameters of spring cone crusher, you can refer to it
9. Before summing up the correct operation method, let's understand the main characteristics of cone crusher: (1) hydraulic system, which can effectively ensure the safe operation of the equipment. When there is a foreign matter in the crushing cavity, the hydraulic system can make the moving cone fall back automatically. When the foreign matter is discharged, the system can make the falling moving cone reset automatically. Maintain the original position of the ore outlet and continue to work
(2) crushing cavity type, which refers to the geometric space formed between the moving cone and the fixed cone. The shape of crushing cavity has a great influence on the performance of the whole machine. The cavity shape of crusher is the main technical index of crushing. The machine has four kinds of cavity designs from coarse crushing to fine crushing. It has six possible combinations, which means that it can best meet the special requirements of users
(3) reliable sealing: labyrinth sealing device is used to replace the water seal used in the past, so that st and impurities can not enter the body, so as to ensure the cleanness of lubricating oil, prolong the service life of sliding bearing and thrust ball bearing, and make the machine run reliably.
(4) convenient replacement: in the past, the replacement of crushing wall of crusher was very slow, The new structure of cone crusher can replace the crushing wall very quickly. Because the upper crushing wall is equipped with a clip, the crushing wall is fixed by jacking up with bolts. The lower crushing wall is fixed by hydraulic nuts. There is no need to add any filling material on the back of the upper and lower crushing walls, so the replacement speed reces the labor intensity of workers
cone crusher is divided into standard type and short head type, which is generally used for medium and fine crushing. The standard type is generally used for secondary damage, that is, medium damage. The short head type is generally used for fine breaking, that is, final breaking. Simons cone crusher has four cavity types. They are very thick, thick, medium and fine. The principle of selection depends on the size of feeding and discharging particles. If the feeding degree is large and the proct size is coarse, select extra coarse type or coarse type, and vice versa. In the calculation of feed size, the maximum feed size of open edge is multiplied by 0.85 as the basis for selecting feed size, and the average size of proct is the maximum feed divided by crushing ratio. Simmons cone crusher standard type is mostly used for open circuit circulation, short head type is mostly used for closed circuit circulation
when selecting liners, users must generally consider three factors: output, power consumption and wear resistance of liners; The change of particle size and the distribution of feed particle size; Hardness of material; Wear resistance of materials
the longer the liner, the higher the power consumption. The short liner is selected for hard materials and the long liner is selected for soft materials. In terms of material distribution, the short liner is selected for fine materials and the long liner is selected for coarse materials. Generally speaking, the distribution of feed particle size should not be more than 10% smaller than that of closed side discharge port. If it is more than 10%, the power consumption will increase and the proct particle size will become flake. The increase of moisture content of viscous materials can affect the throughput of materials. Generally speaking, the moisture content of materials is less than 5%. In the use of power: standard cone crusher should reach 75% ~ 80%, short head cone crusher should reach 80% ~ 85%
cone crusher e to its bad use environment, st, and some use of the unit maintenance is not in place, often appear in the operation of a variety of problems, generally speaking, cone crusher in use and operation should pay attention to the following problems, in order to ensure the normal operation of the machine
ring the operation, the feeding should be uniform and no segregation is allowed. If the feeding is uneven, the proction capacity will be reced, the proct size is too large, the spring action is frequent, the pressure of the bowl bearing is high, and the power consumption will rise
1. There should be iron removal device to prevent the crushing chamber from iron overload. If iron overload occurs frequently, the shaft may be broken
2. Full load proction is required, otherwise the proct will be too coarse
3. The crushing ratio distribution in the proction line should be reasonable, so as to maximize the efficiency of the crusher
4. The spring pressure should not be too tight. If the pressure is too high, the shaft will be broken. If the pressure is too small, the spring will jump frequently, which will affect the normal operation of the crusher, and the proct size will become coarse
5. The temperature of lubricating oil should not be too high or too low, otherwise the operation of the machine will be affected
6. The lubricating oil should be changed frequently, and it should not be too dirty. If it is too dirty, it will accelerate the wear of gears, bowl shaped Bush and shaft sleeve, and even cause the shaft sleeve to grind to death
7. The drive belt should not be installed too tightly, otherwise the drive shaft will not rotate flexibly or break; It can't be too loose, otherwise it will cause the crusher boring
8. The feeding material should not be too wet and sticky, and the fine particles should not be too much or too large, otherwise it will cause stuffy car
9. Ore accumulation at the discharge port of the crusher will also cause choking.
10. The machine hydraulic system of Xing coal mine uses the hydraulic system to adjust the size of the ore outlet of the crusher, and the hydraulic system can effectively ensure the safe operation of the equipment. When there is a foreign matter in the crushing cavity, the hydraulic system can make the moving cone fall back automatically. When the foreign matter is discharged, the system can make the falling moving cone reset automatically.
