Light Weight Is Focus Of Jaw Crusher Development

The jaw crusher is invented by the Americans EW Blake

. Since the advent of the first jaw crusher has been 140 years of history. In this process, its structure has been constantly improved. Jaw Crusher is simple structure, easy to manufacture, reliable, easy maintenance, widely applied in metallurgy, mining, building materials, chemicals, coal and other industries. Very different between the technical level of the jaw crusher manufactured by the domestic manufacturers, a small number of manufacturers of the products was close to the world advanced level, and most of the manufacturers of the products with the world advanced level compared to the gap.

The jaw crusher machine weight is generally higher than with the specifications of the foreign crusher. Reduce the machine weight is also an important topic. The cracker rack accounted for the whole quality of a large proportion of (casting rack accounted for 50%, welded rack 30%). Abroad jaw crusher are welded rack, and even the moving jaw of welded structures. The jaw crusher welded rack is the development direction. Jaw crusher frame structure design is unreasonable instance there are many reason for this is not crusher actual force conditions to layout the ribs. Movable jaw structure design should be based on the moving jaw force based on the conditions to meet the strength and stiffness requirements to minimize the quality. In addition, the rack, movable jaw finite element study, rack, movable jaw finite element optimal design to achieve the rack, the light weight of the moving jaw have a high degree of reliability. Also, reasonably determine the parameters of the crusher, crushing chamber crusher power balance and so can make use of calculations to optimize the design. In short, the modern design method should be used instead of the conventional design method, and gradually make the domestic jaw crusher to achieve world-class level.

Red Star machine is the world's leading rock and mineral processing equipment manufacturer, the company attaches great importance to international technical exchanges and cooperation, and has introduced advanced technology and processes of the United States, Germany, Australia and other countries, with a hundred sets of sets of production equipment, has established the International advanced production lines and first-class modern testing base. Million units (sets), broken equipment has been installed worldwide since the late 20th century.
