Development of crushing machinery industry has been driven by the rapid pace development of economic growth together. In order to accurately understand and report the trend of crusher, the reporter came to the Machinery Association, he is going to get a in-depth understanding on crusher include crushing principle and the development of crusher, also on models of crusher and other aspects
With the development of economy, there is a larger requirement of the production. Under the rapid development of mining, metallurgy, coal and other international relations livelihood of the industry, stimulating the relevant crusher equipment has entered a period of development. In order to make a fundamental forecast tends of crusher equipment on the whole understanding for the current state development of crusher, Reporters came to Oman where the mining industry is relatively developed, interviewed Professor Zhang whom is the vice president of the Association of Mining Machinery, discussed about the history and development tends of crusher industry in details
Focus on the questions from reporter, Professor Zhang said," everything developed follow its history and current status, we should start from these areas when analyzing the trends of crusher machinery." Next, Professor Chang talked about the principle and the crushing system of crusher equipment. The solid material is pulverized by external force, to overcome the cohesive force to achieve the crushing process. In general, crusher is used to make the large raw material into small particles, With the deepening fragmentation of work , the total surface area increasing ,variety of physical and chemical effects of the reaction rate gradually accelerate also Therefore , the crusher is widely used in many industries with variety of materials
In the crushing system, Professor Zhang said: "in production, according to the nature of material, the feeding size, requirements of crushing ratio, and the production scale etc., to determine the type and the models of crusher, because different crushers have different crushing systems, Crushing system include crushing stages and the process in each stage, crushing stages main determined by the requirement crushing ratio of the raw material and the type of crusher. We choose the primary crushing system when in one crusher that can meet the requirements of crushing ratio and production capacity, if there is a need to using two or three crushers to meet the demand though multi- stage crushing, we use secondary or tertiary crushing system
"How about the effect of crushing" Reporter skeptical , Professor Zhang continued: " The more crusher stages , the more complex of the system , the system will take up a large area , high construction costs, low labor productivity , large dust , higher maintenance costs etc problems , however, with the development of various industries , crushing ratio requirements gradually increased, in order to meet this kind of demand , the production of crusher can be improved by reduce crushing stages, prompting the crusher with big crushing ratio , high performance and large-scale, If you visit our association crusher network , you can find a lot of new crusher equipments , with simplify crusher system, less crushing sage , small footprint , lower power consumption and production costs. Develop new direction of crusher industry " " I have understand, thank you," reporter said with gladness, the knowledge from original expert on the industry is so depth and easy to understand, expert explain various aspects worth considering.
