Mechanical Evolutionary Process in Human World

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 7, 2011 -- Humans become "modern" sign is manufacturing tools. The Stone Age, all kinds of ShiFu stone hammers and wood, leather simple rough tool is the pioneer of the machinery to come. Made from simple tools to make more than the evolution of parts, components of modern machinery, experienced a long process.Drum dryer

Thousands of years ago, humanity has created a device used for grain and smash the mortar and ground, used to carry water JieGao and the engineer-in-chief, equipped with the wheels of the car, sailing in rivers of the ship and OARS, OARS, steering gear, etc. The use of the power, from their own physical strength, the development of livestock, hydraulic and wind power. The materials from natural stone,Drum dryer,Ore beneficiation and other machines are the stone crushing equipment, wood, earth, leather, development to artificial materials. The earliest artificial material is ceramic, making ceramic vessels clay car, already is a dynamic, transmission and work three parts of the complete machine.

Mankind from the Stone Age to the Bronze Age, and then to the iron age to blow of the flourishing development of the drum wind played an important role. Are strong enough for the drum wind, then can make the metallurgical furnace get a high enough temperature, can have refined in metal from ore. In China, the 1000 ~ 900 years before the timbal is already in the drum wind,

Impact crusher,Impact crusher,Flotation cells and other machines are the main ore dressing equipment on the market. and gradually from human drum wind development to work and hydraulic drum wind.

15 to 16 centuries ago, mechanical engineering development is slow.Ore beneficiation,Ore beneficiation and other machines are the sand making equipment, But in one thousand, in the practice of project, in mechanical development, it has accumulated much experience and technical knowledge, became the mechanical engineering development of important potential. 17 centuries later, capitalism in the English, French and European countries appear, commodity production started to become the center of the social problems.

The late eighteenth century, the application of the steam engine from mining promotion to the textile, flour, metallurgy, etc. The main material of made machinery gradually from wood to switch to more tough, but it is difficult to use the manual processing of metal. Mechanical manufacturing industry started to form, and in a few years to become an important industry.
