Bionic Horizontal Grain Shape Cement Mill Roll Wear Test And The Analysis Of Wear Mechanism

As we know, the cement plays a key role in the construction of China’s modernization,especially in recent years when China’s economy is developing fast. As one of the four basicconstruction materials, China’s cement industry is facing with a promising future as well aschallenges, for example, higher technology requirements.The production of cement is closely related to wear-resistant materials, so thetechnological level of cement industry relies on the production and application ofwear-resistant materials.The survey has found that the roller press, the core component ofcement production, has such shortcomings as short service life, serious surface wear, lowgrinding efficiency, and lack of maintenance.Therefore, it is a common concern in thecement industry to solve the problems of cement roller press grinding roll.Over thousands of years of evolution, the non-smooth surface of living creatures isformed to adapt to the environment and perform special functions. Studies show that surfaceof living creatures can show good wear resistance and anti-fatigue features. The main workof this paper is to proceed from the point of view of bionics,a roller press, roller press teststand and computer experiment platform using the simulation test, simulation analysis, thereal test study, come to design the best provide an important basis of the size of the modelparameters, cement roller press wear resistance. Specific work includes the followingsections:1、Working principle and wear mode of high pressure roller millRead References to understand the structural characteristics of cement roller press,getting to know the wearing process and mode of roller press to provide a reliable basis forfollow-up work.2、The test stand and the design and processing of grinding rollers of the roller pressTake shell morphology as a guide to design the non-smooth surface of the grindingrollers and determine the size and distribution rules of the surface. Design and produce thetest stand and bionic grinding rollers according to the working principles of the roller pressroller press. 3、Study on the wear resistance of grinding roller samples and analyze its mechanismSelect quartz sand as an abrasive material and conduct extensive wear testing.Bycarrying out regression analysis, determine the regression equation of abrasion loss and getthe value for the best grinding roller.4、Finite element structural analysis of standard grinding rollersSimulation analysis method is the trend of the development of theoretical research inrecent years, so you can save costs and reduce the number of trials. It is a useful test processimprovement and supplemental roller press roller and material force, that the material layertheory of smooth grinding rollers for structural analysis.5、Analysis on the structure of bionic stripes shaped grinding roller and its wearresistance mechanism.Use simulation analysis methods to conduct structural analysis stripes shaped grindingroller, study the press and strain feature between different structures, and compare it withsmooth-surfaced grinding roller models. By studying on the wear resistance of non-smoothstructure, this paper provides theoretical evidence for abrasion tests.
