HC Valve Network: In China, over two thousand years BC, appeared in the most crushing single cylinder tools? Ball and socket. Mortar and pestle for further evolution of the BC 200 to 100 years before polishing mill. These tools use the leverage, the initial prototype with a broken machine, but their action is still intermittent grinding.
Early action by continuous grinding machine is broken the fourth century BC, invented by public transport class animal mill, another crushing action and a continuous roll grinding machine is broken, it appeared later in the grinding time. Year two hundred years later, Du Yu and other Chinese in the foot pestle and grind on the basis of animal research out of water as the driving force to the connection machine Shueiduei, with two water mill, water mill and so even turn to productivity to a new level . In addition to grain processing for these machines, but also extended to other material on the crushing operation.
Broken machinery in the modern steam engine and electric motors and other machinery, after the gradual improvement and extension have created. Appeared in 1806 the steam-driven roller crusher; 1858, the United States, Black invented the broken rock jaw crusher; 1878, the United States has developed a continuous cycle of action crusher broken, the intermittently productive than crushing action of jaw crusher; 1895, the United States, William invention lower energy consumption impact crusher.
At the same time, grinding machine has also been a corresponding development in the early 19th century, the ball appeared widely used; 1870 in the mill, based on the development of a uniform size marker rod mill; in 1908 it created Since the mill without grinding media. 30 to 50 years the twentieth century, the United States and Germany have developed a roll bowl mill, roller mill and other vertical type disc pulverizers.
The emergence of these broken machinery has greatly enhanced the effectiveness of crushing operations. However, due to the crush characteristics of various materials, each with different products in different industry size requirements are different, so he has created a different working principle by a variety of broken machines smash operations, such as roller-mill, vibration mill , turbine mill, jet mill, fan mill, sand mill, colloid mill and so on.
To the early 70s, has produced 5,000 tons of output per hour, maximum feeding large diameter of 2,000 mm gyratory crusher, and the material can be pulverized to a particle size less than 0.01 micron colloid mill.
Solid materials by mechanical crushing There are five main methods, namely, extrusion, bending, splitting, milling and impact. Use the first four are static, the last the application of kinetic energy. In the vast majority of broken machinery, materials of two or more often under the effect of grinding method was crushed, for example, in the gyratory crusher, the main application of extrusion, splitting and bending; the ball mill, the main impact and abrasive applications.
With the development of technology, broken machinery development so far has made considerable progress. Especially after 90 years, broken machinery production and sales growth, adding broken machinery manufacturing enterprises are increasing, so that as many as thousand broken machinery manufacturing enterprises at home, can produce 0.5 ~ 30t vibrating crusher, 4 ~ 24t Static Roll Crusher and 16 ~ 30t tire crusher complete specifications and varieties more complete range of products, the basic form to self-development and production of complete crusher manufacturing system, its technical level and international advanced level is gradually narrowing the gap between. This high growth situation, there will be pieces of broken machinery supporting industry to a new period of development.
Recent years, Shanghai Machinery Co., Ltd. to represent the world state, in broken machinery in the field a number of emerging technologies to streamline the business. As the well-known brand equipment and gravel crushing and screening aggregate processing equipment research and development, manufacturing and export base of national importance, the Shanghai World State Machine Co., Ltd. devote ourselves to developing high efficiency of crushing equipment. 20 years, the company over 100 industry experts dedicated to the advanced technology to streamline the crushing mill equipment research and development, has developed with international technical standards Crusher: PE jaw crusher, PF Impact Crusher, PY Cone Crusher, HPC cone crusher, JC jaw crusher, (E breaking series, counter-breaking series, cone break series, the impact of broken series) mobile crushing, hydraulic drive track-type mobile crushing plant, PFW European version of the Crusher, etc.;
