  • The development of gnathic type crusher and wide application

    19 centuries 40 time, the upsurge extracting gold of North America has very big stimulative effect to the development of crusher of type of another name for Hubei province, 19 centuries middle period, the development of crusher of type of another name for Hubei province of a variety of types comes out and win wide application, last century end, whole world oneself the crusher of type of another name for Hubei province that has a variety of 70 different structures obtains patent. And this caused F the more thorough research of bisect class theory, but did not form dimensions all the time. Till 20 centuries 50 time, ai Lisi checks Er silent this the company just begins extensive research to classification the job. 60 time reach the conclusion of great sense. As the development of research, people know high power classifications, Jk can use improvement energy efficiency and reduce cost ridge. Contemporary the crusher of type of another name for Hubei province that crusher of the most commonly used type of another name for Hubei province is lay mines gram and more latter-day crusher of made type of odd bracket another name for Hubei province. The biggest weak point of crusher of type of another name for Hubei province is them only inside loop of a job half the time works. BH*Bergstrom puts the discovery when studying odd grain crusher, when the classifications fragment in putting air bumps plate, arise 2 times to classification apparently, 45% what the function that the fragment that classifications has takes energy of total share grade, if can make full use of 2 times to classification energy, can rise classification efficiency. Also somebody points out, lesser abidance bear is more hopeful than the powerful concussion of short time classification stock. Schonert considers to make clear, if make large quantities of brittleness stock grain get the pressure of 50Mpa above, can smash by “ makings layer ” is managing a considerable energy. The academic ” that current “ expects the layer smashs oneself to smash bound place is accepted, the new facility that develops according to expecting bedding is talked has American Nuo the awl crusher, inertial and conic crusher of Russia waits the Pan Yuan coming back of De Baige company a moment.
