To improve the durability and reliability of cone crusher frame mainly due to two aspects:
1. When the frame is designed, the mechanical strength of the frame is ensured, and the frame has enough strength, rigidity and accuracy, in particular, the structure is determined by the actual conditions of the frame.
2, as far as possible to avoid or reduce the \"over iron\" and overload phenomenon, do not let the broken machine in the frequent overload conditions, to ensure that the material is very important. It is best to use the rotating fabric and automatic control feeding, in short, the correct use, careful maintenance, timely maintenance can guarantee the normal operation of cone crusher and extend its service life, improve the crushing machine operation rate and give full play to its potential.
The details are as follows:
1, the crushing strength of the cone crusher is with the material hardness, the material is uniform and the size of the material deformation. Material deformation degree is determined by the displacement of the material in a working cycle: the larger the displacement, the larger the deformation amount, and the smaller the. The displacement of the material in a working cycle is changed, so the size of the crushing force is a constant value. Due to crushing force F is, change, FY values when large and small from time to time, when the FY values greater than at the beginning of the spring pressure, the spring beating, so that the mating surface wear, uneven feeding, too aniseed block and iron will overload the, causing spring vibration system, forces the support ring impact machine frame to taper fit surface damage. Which had large material block and iron, the general is relatively rare, and the feeding is not caused by the overloading of cone crusher. In the crushing workshop of a mine, it is found that the lining plate of the broken machine is premature to be scrapped due to the serious deviation. The improper layout of the hopper, the segregation of the material, and the uneven of the feeding amount, will lead to the overload of the crusher, which makes the spring bounce frequency, and accelerate the wear of the mating surface. Not only that, but also cause the power increase, the production capacity is reduced, the lining board premature grinding, the product granularity is not equal to the adverse consequences. Therefore, the material flow in the broken cavity should be uniform, and the distribution of the material distribution along the circumferential direction of the crushing cavity is the important factor to improve the durability and reliability of the cone crusher.
2, for the conditions of the broken shop, the best equipment to install the rotating fabric and automatic feeding control system, this will bring many advantages: improve production capacity, improve product quality, extend the service life of the lining board, to avoid overloading the cone crusher, improve the durability and reliability of crusher. Cone crusher frame is the foundation of all parts. Therefore, it is required that it has enough strength and rigidity to ensure the durability and reliability of cone crusher.
