A Brief Review of the Development of Rock Crusher

The following will show you the brief review of the development of the rock crusher.

The rock crusher was created after the gradually popularizing and perfecting of steam engine and motor power machinery and its history can be traced back to eighteen tens when the first steam engine driven rolling crusher in the world was born; in 1858 in the United States, Black invented the first rock crushing jaw crusher. And later, with the development of productive forces, the jaw crusher cannot meet the need of crushing technology. So, on the basis of jaw crusher, Americans made cone crusher with continuous crushing actions in 1878, whose production efficiency was higher than that of jaw stone crusher with intermittent breaking action; because of the need of man-made sand, natural sand cannot meet the need of important constructions.

In 1924, the Germans were first to develop single and double, two types of rock crusher, structure of which was similar to the modern cage crusher. But no matter when analyzed in structure or in the working principles, rotor crusher has characteristics of crusher. By 1942, the German Andreson invented the AP series impact crusher which was similar to modern impact crusher structure based on the structure characteristics and working principle of the squirrel cage crusher and hammer crusher. This crusher machine had obtained rapid development because of its advantages of higher production efficiency, processing many kinds of materials, simple structure and easy to move. Then, with the further development and technology improvement of crushing and screening of crushing theory, coming out the three stage crushing equipment - impact crusher, which could be used to crush river gravel, granite and other kinds of stone.

The development of impact crusher in China was relatively late, so not until to the last century 50's did our country had stone crusher in real meaning. Therefore, most of the crushing and screening equipment in China were born in 1950s. Before the 80's of last century, impact crusher made in china was limited to the processing of hard materials, coal and limestone for instance. Until the end of last century eighty's, we made introduction of KHD hard rock impact crusher into China to fill the domestic blank of high hardness crusher. But the technology is behind abroad for more than 20 years.

May you have a good knowledge of the development of the rock crusher.
