The history of the development of the crusher can be traced back to ancient times, experienced from the manual to the steam era, and then to the process of intelligent mechanical evolution. The following are the main stages of the development of the crusher:
1. Ancient stage:
The simplest crushing tool, chujiu, appeared in China as early as 2000 BC.
– 200 to 100 years ago, the pestle and mortar further evolved into a treadle, and these tools initially had the prototype of a crushing machine, but the crushing method was still intermittent.
– In the fourth century BC, the public transport team invented the animal mill, which is a crushing machine that uses continuous crushing. Later, the roller also appeared as a continuous crushing machine.
– AD two hundred, after China du yu and other people on the basis of the pedal reef and animal grinding, developed for hydraulic impulsion of the machine turn millstones, even two water, water mill etc, greatly improving the efficiency of crushing.
2. Modern stage:
In 1806, the roll crusher driven by steam engine appeared, marking the crusher’s entry into the steam era.
In 1858, the American E.W. lake (Blake) invented the jaw crusher for breaking rock. This kind of crusher has the advantages of simple structure, easy manufacture, reliable operation and convenient maintenance, and is still widely used today.
In 1878, the United States developed a rotary crusher with continuous crushing action, whose production efficiency is higher than that of the jaw crusher with intermittent crushing action.
In 1895, William of the United States invented the impact crusher with lower energy consumption.
3. Modern stage:
With the continuous development of science and technology, the crusher industry is also constantly carrying out technological innovation to improve efficiency, reduce energy consumption, reduce maintenance costs, and improve production efficiency.
– The crusher is developing towards large-scale, automation, environmental protection and optimization. Combined with China’s ore characteristics and mechanical processing level, the development of advanced principle, simple structure, high manufacturing level, high efficiency, low consumption, durable crusher mining machinery will be the future development direction. In general, the history of the development of crushers is a history of evolution from manual to mechanization, and then to intelligence. With the continuous development of science and technology, the crusher will play an important role in more fields and bring more convenience to human production and life.
