Quartz Grinding Process Equipment Detailed introduction

Liner Structure of Quartz Grinding Process Equipment

The scale of China’s Quartz Grinding Process Equipment industry is constantly developing and expanding. At present, it has become a very competitive product at home and abroad, but we must continue to be proud of it. We must continue to increase the research on the basic technology and components of the Quartz Grinding Process Equipment and strengthen it. Independent research and development capabilities of Quartz Grinding Process Equipments in China. SBM is an industry expert in this regard. The following is the research and improvement of the structure of the Quartz Grinding Process Equipment liner.

1. Quartz Grinding Process Equipment Liner Structure

Lining plate is an important part in Quartz Grinding Process Equipment. Its structure is simple, but it affects the productivity, specific energy consumption and grinding power of Quartz Grinding Process Equipment. When grinding the material, the Quartz Grinding Process Equipment will directly contact the material, and will be ground and squeezed. The impact force is very large, which will cause severe wear. It is one of the main vulnerable components of the Quartz Grinding Process Equipment. Therefore, prolonging the life of the liner has become a problem that everyone attaches importance to. The traditional lining design method is to concentrate the force at a certain point of the lining, and then divide it by the area of ​​the lining to obtain the force of the lining. Then study and design the structural parameters of the lining. This method ignores the lining. The load of the plate is unevenly distributed. Analysis of the discarded liner shows that the wear cross section of the liner is severely worn in the middle with less wear at both ends; in the longitudinal section, the wear is less in the direction of the inlet and more in the direction of the outlet. At the same time, the position of the combined force point of the grinding power of the liner is changed, so its force is random. We need to carefully analyze the force of the liner, and on this basis, improve the structural parameters of the liner, and improve the Quartz Grinding Process Equipment liner. Service life. The fuzzy random theory used in this paper provides a theoretical basis for this research.

2. Fuzzy Random Theory Analysis

Fuzzy stochastic theory combines fuzziness and randomness, and it includes fuzzy mathematics, random mathematics, probability theory, statistics and other disciplines. Fuzzy stochastic theory can solve the problems of uncertainty and engineering data.

The fuzzy reliability analysis method needs to prepare sufficient data to determine the membership function of the structural parameters. Under actual circumstances, it is not easy to obtain accurate data with uncertain quantities, and various methods such as empirical method and experimental method are needed to obtain the data. Interval expectations with fuzzy numbers are treated as random sets and interval averages, and are called probability distributions. This paper introduces the representations of mean probability, variable and covariance, etc., and studies the relationship between the possibility of weighted fuzzy number interval and the interval random average.

The structural parameters of the improved lining board are very reasonable: the stress distribution of the improved lining board has been greatly improved, but the material has not basically increased; in addition, the safety factor of the lining board has been significantly improved, which can prolong the service life of the lining board and reduce the milling mill grinding cost.

3. Improve The Structural Parameters Of The Liner

When designing the liner in practice, for convenience, it is usually divided into two parts from the middle position of the height of the liner. We made the following modifications to the movable jaw liner: one liner was changed to two identical combined liners; the height of the boss was changed from 30mm to 15mm; the thickness was changed from 20mm to 15mm; while maintaining the top and bottom pitches and teeth The root is unchanged, its height is changed from 30mm to 35mm, and the width of the tooth top is changed from 15ram to 12mm; the sum of the weight of the two liners is reduced by 18.26kg, which saves production and use costs; the results of finite element analysis show that After the modification, the stress distribution of the liner is greatly improved, and the stress distribution is relatively uniform.

In this paper, the lining of the Quartz Grinding Process Equipment is severely damaged during material processing and the life is short. The fuzzy random theory is used to load the lining and the stress distribution of the lining is calculated. analysis. By changing the structural parameters of the lining, improving the stress distribution of the lining, ensuring that the energy consumption is reduced, the service life of the lining is extended, and a reliable theoretical basis is provided.
