China Grinding Mill History
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 medium-speed
grinding milling machines can be traced back to 19th century history of 50 years. Raymond
grinding 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 grinding mill are continuously developing and thus the birth of three-
ring medium speed grinding mill, and its increasingly wide range of uses, and can with
appropriate conveyor and sorting equipment can be easily formed Kuangshi Grinding Line.
Three-ring medium speed grinding mill in China relatively late, to the 50s last century,
our country really has a broken machine. Therefore, China's crushing and screening equipment
are over 50 years came out. 80s in the last century, we made the grinding mill is limited to
processing of coal and limestone and the like in the hard material. Until the late eighties
of last century only developed country hard rock grinding mill, not only filled a gap
grinding mill high hardness. Liming Heavy Industry Science and Technology to further in the
Raymond grinding mill produced based on the development of three-ring medium speed grinding
mill.
Three-ring medium speed grinding mill is a kind of ore crushing machinery. Its
technology in recent years along with modern high-tech and new materials industry and
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. But now our domestic grinding mills and foreign
compared to the gap there is still some, therefore, the future direction of development of
grinding mills mainly in the following areas:
First, the need to
Grinding Mill the
existing structure of the better three-ring medium speed grinding mill on the hard ore
crushing capacity and ease of maintenance, its main focus on board hammer, improved rotor
structure for on the replacement board and hammer mounted card; counter stand (broken cavity
shape) of the structural optimization of an ore crushing rate increase and energy
efficiency.
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.
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 grinding 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.
Fourth, to meet market and customer needs, three-ring medium speed grinding mill being
serialized standardized, large-scale development.
Fifth, adhere to technical innovation, and gradually get rid of the products of a single
introduction and imitation.
