The history of crusher
The most simple tool for crushing appeared two thousand years before Christ in China, the Chinese name is -chujiu,we can call it “ball and socket”. The further evolution of the ball and socket is foot pestle from 200 to 100 years BC. These tools use the leverage, the initial prototype with a broken machine, but their action is still intermittent grinding.
The ball and socket
The earliest use of continuous crushing action of the crusher machine is the Chulimo named mill in the fourth century BC invented by Shuban Gong, the other crusher machine with continuous grinding action is the roller grinding machinery, it appeared later than the mill in that period. Two hundred years AD later, Du Yu and other Chinese research out of a machine named Shuizhui forced by water power on the basis of the foot pestle and mill, and even two water mill, water transfer even grinding, etc., to improve production efficiency to a new level . In addition to these machines for grain processing, but also extended to other materials on the crushing operations.
Crushing machinery in the modern times created after the improvement and promotion of the steam engine and electric motors and other power machinery. In 1806 a steam engine-driven roll crusher appeared; 1858 the jaw crusher was invented by Blake from United States for crushing rock ; the development of the United States in 1878, with continuous gyratory crusher crushing action, the production efficiency is higher than for the intermittent crushing action of the jaw crusher; 1895, William from the United States invented a low energy impact crusher.
The world’s first cone crusher is primary designed by American Symons brothers. Untill now, many domestic manufacturers of crusher name their crushers “Symons”. It is about 1920 that Symons Cone Crusher applied in crushing mills. In 1948, an American company researched and developed the hydraulic cone crusher, It can expel the uncrushable materials that entered into the crushing cavity, and can adjust the discharging mouth size during operating, producing the granularity with a uniform size. To the 1970s, along with the development of technology, automatic controller has been developed to be used to control the hydraulic cone crusher. Crusher has advantages of big crushing ratio, high efficiency, less energy consumption and uniform granularity size.Suitable for medium,fine,and superfine crushing of hard rock and ore materials.
The emergence of these crushing machines have greatly improving the effectiveness of crushing operations. However, due to the different of the crushing characteristics of each variety of materials, different sectors of the product size requirements are different, people would have developed a variety of mechines for crushing operations base on different principles of work .
