Modern machinery is broken after the steam engine and the electric motor power machinery such as the gradual improvement and promotion have been created. 1806 emerged with a steam-driven roll crusher machine; in 1858, the United States invented the broken rock Blake jaw crusher; 1878 United States developed with continuous crushing action of gyratory crusher , its productivity is higher than for intermittent crushing action of jaw crusher; in 1895, the United States, William invention low energy impact crusher.
Twenty20 1980, 800 tons of material per hour crushing large jaw crusher machine feed size has reached about 1800 mm. Commonly used jaw crusher has two elbows plates and single brackets. The former moving jaw at work only for simple swing arc, so called simple swing jaw crusher; the latter, while the swing arc is still up and down movement.
Development Status:
Domestic jaw crusher manufacturer technical level difference is very poor, there are few manufacturers of the products was close to the world advanced level, while most of the larger manufacturers of products with the world advanced level in the gap. Jaw crusher frame representing a large proportion of the whole quality (50% cast chassis, chassis welding 30%). Foreign jaw crusher are welded frame, even moving jaw also welded structure. Jaw crusher machine with welded frame is the development direction. Domestic jaw crusher frame structure has many examples of poorly designed, the reason is not according to the crusher to the actual arrangement of the forces stiffener
Jaw crusher machine ensure optimal performance of the underlying factors are moving jaw has the best sports feature, this feature is designed to optimize the aid agencies get. Therefore, jaw crusher crusher design optimization is a fundamental method has the best performance guarantee. With which organizations to optimize design for a variety of modules to optimize the design of the crusher, get the best moving jaw motion characteristics.
