Research and Improvement on Tooth Plate Structure of Gold Ore Crusher

The size of China's crusher industry continues to grow and develop, at home and abroad have now become very competitive products, but we must not victorious not hungry, we must continue to increase crusher basic technology and components of the study and enhance our country Crusher independent research and development capabilities. SBM machines are the industry leader in this regard. The following is a study and improvement of the tooth plate structure of the gold ore crusher.

Tooth plate is an important part of the crusher, the structure is simple, but affects the crusher productivity, specific energy and crushing force. gold ore crusher in the broken material toothed plate will be in direct contact with the material, will be grinding and extrusion, to withstand the impact is very large, it will have serious wear and tear, crusher is one of the main vulnerability components. Therefore, to extend the life of tooth plate become a problem everyone pays attention to. The traditional method of tooth plate design is to concentrate the force at a certain point of the tooth plate and then divide the stress area of ​​the tooth plate to obtain the force of the tooth plate. The structural parameters of the tooth plate are then studied and designed. Ignoring this method The tooth plate load is unevenly distributed. Analysis of discarded toothed plates shows that the wear of the toothed plate is the most serious on the cross-section of wear and tear of the middle part, with the least wear on both ends. On the longitudinal section, the wear direction is less in the material inlet and more in the discharge opening. At the same time, the location of the force point of the toothed plate crushing force is changing, so its force is random. We need to carefully analyze the force condition of the toothed plate. Based on this, we can improve the structural parameters of the tooth plate and improve the use of the tooth plate of the gold ore crusher life. The fuzzy stochastic theory adopted in this paper provides theoretical basis for this research.

Gold Ore Crusher

Fuzzy stochastic theory combines fuzziness and stochasticity. It includes fuzzy mathematics, random mathematics, probability theory, statistics and many other disciplines. Fuzzy stochastic theory can solve the problem of uncertainty and engineering data.

The fuzzy reliability analysis method needs sufficient data to determine the membership function of structural parameters. In the actual situation, it is not easy to get accurate data of uncertain quantity, and we need to obtain the data by many methods such as empirical method and experimental method. The expectation of interval in which fuzzy number appears is regarded as random set and interval average, which is called probability distribution. This paper introduces the representation of the means, variables and covariances, and studies the relationship between the likelihood of weighted fuzzy numbers and the random mean of intervals.

Improve the structure parameters of tooth plate is very reasonable: improved tooth plate greatly improved the stress distribution, but the material did not increase; In addition the tooth plate safety factor improved significantly, so you can extend the service life of the tooth plate and reduce crusher crushing costs.

In actual design, the tooth plate, for convenience, is usually divided into two parts from the middle of the height of the tooth plate. We modified the moving jaw gear as follows: Modify a gear plate into two identical combined plates; the boss height changed from 30mm to 15mm; the thickness changed from 20mm to 15mm; Root unchanged, the height from 30mm to 35mm, tooth top width from 15ram to 12mm; the revised weight of two tooth plates and a decrease of 18.26kg, thus saving production and use costs; finite element analysis showed that , Modified tooth plate to improve the distribution of stress, the stress distribution is relatively uniform.

In this paper, the tooth plate of the gold ore crusher is seriously damaged and has a short life span during material processing. The stochastic theory is used to load the stress state of the tooth plate, and the stress distribution of the tooth plate is calculated. The finite element analysis. By changing the parameters of tooth plate structure and improving the stress distribution of the tooth plate, the energy consumption is saved and the service life of the tooth plate is prolonged, thus providing a reliable theoretical basis.

Professionalism and innovation are the business cards of our SBM machine gold ore crusher. SBM has made great efforts in the research and development of the gold ore crusher. As the wearing part of the gold ore crusher, the service life of the gold ore crusher has been greatly prolonged. Welcome to buy.
