Three-ring medium speed mill in China relatively late , to the 50s last century , our country really has a broken machine .
Second, the research and development of high toughness, high wear-resistant materials, the new board to improve board hammer hammer the life and increase productivity.
Fifth, adhere to technical innovation , and gradually get rid of the products of a single introduction and imitation.
Third, the application of modern mechatronics technology and modern control methods ( such as hydraulic technology Electronic (Technology) , and continuously improve the three-ring medium speed mill automation to reduce labor intensity and increase productivity. For example: the application of modern computer-aided design optimization of structural parameters of counter- frame , to increase energy efficiency and a broken rates of ore . But now we have the domestic mills and foreign relative ratio of a gap there is still , therefore, the future direction of development of mills mainly in the following areas:
First, the need for the existing mill structure and thus improve the three-ring medium speed mill on the hard ore crushing capacity and ease of maintenance , its main focus on board Hammer, improved rotor structure for the board replacement and installation card hammer ; counter stand ( broken cavity -shaped ) structure optimization, a crushing rate increase ore and energy efficiency . Raymond mill scrap the emergence and development and the development of the industry is closely related to the beginning to deal with only some thin material , with the deepening of understanding and processing of hard materials crushing superiority of the materials show , a variety of Raymond Mill are continuously developing and thus the birth of three-ring medium speed mill , and its increasingly wide range of uses , and can be accompanied by appropriate conveyor and sorting equipment , the composition can be easily crushed ore production line .Grinding Mill development will be a history of recent decades , the world's popular and dominant Raymond , mostly in the United States on the basis of Newell 's derived , the possession of nearly Qi Cheng , the first The development of medium-speed mill dating back to 19th century history of 50 years . Therefore , China's crushing and screening equipment are over 50 years came out .
Fourth , to meet market and customer needs , tricyclic series medium-speed mill being standardized , large-scale development . 80s in the last century , we made the mill is limited to processing of coal and limestone and the like in the hard material . Zenith Science and Technology to further in the Raymond mill produced based on the development of three-ring medium speed mill . Until the late eighties of last century only developed country hard rock mill , not only filled a gap mill high hardness .
.
Three-ring medium speed mill is broken ore Machinery A . Its technology in recent years along with modern high-tech and new materials industry and Brake System developed a new crush engineering technology, has become the most important industrial minerals and other raw materials, processing technology , one of the development of modern high-tech industry Of great significance
