Blake jaw crusher

By American E.W. Blake invented. Since the first inception, jaw crusher’s structure to be constantly improved. The jaw crusher has the advantages of simple structure, easy manufacture, reliable work, convenient to use and repair of advantages, so in the metallurgical, mining, building materials, chemicals, coal and other industries are widely used. In order to improve the jaw crusher performance and improve the work efficiency, abroad has to develop all kinds of special-shaped jaw crusher. In the early years, Germany and Soviet Union to develop hydraulic jaw crusher. It aims to improve the moving jaw swing frequency to increase production, but also to achieve the hydraulic adjusting discharge orifice, hydraulic overload protection and load starting. West Germany made impact jaw crusher, the former Soviet Union also made vibration jaw crusher ( also called inertial jaw crusher). They are on the movable jaw vibration impact crushing material, so as to improve the crusher performance. East Germany once had made a simple pendulum double cavity jaw crusher, the United States produced pendulum double cavity jaw crusher. Its characteristic is that the intermittent work into a continuous work, so as to improve the work efficiency of crushing machine. The Soviet Union made a double-acting jaw crusher. The crusher is the original two crusher removed from the front wall and opposed. The movable jaw to two synchronous operation, the eccentric shaft end is provided with a pair of open.

The status of jaw crusher Technology

The jaw crusher is by American E.W. Blake ( Black ) method. Since the first jaw crusher ‘s inception, has been # years. In this process, the structure to be constantly improved. The jaw crusher has the advantages of simple structure, easy manufacture, reliable work, convenient to use and repair of advantages, so in the metallurgical, mining, building materials, chemicals, coal and other industries are widely used. In order to improve the jaw crusher performance and improve the work efficiency, both at home and abroad have developed a variety of special-shaped jaw crusher. In the early years, Germany and Soviet Union to develop hydraulic jaw crusher. It aims to improve the moving jaw swing frequency to increase production, but also to achieve the hydraulic adjusting discharge orifice, hydraulic overload protection and can load starting. The former West Germany made impact jaw crusher, and the former Soviet Union also made vibration jaw crusher ( also called inertial jaw crusher). They are on the movable jaw vibration impact crushing material, so as to improve the crusher performance. The former home had been, for some reason can not continue development. Yuan Dongde once had made a simple pendulum double cavity jaw crusher, the United States produced pendulum double cavity jaw crusher. The Beijing Design Institute and Hunan University have been developed in cooperation with the factory of double cavity jaw crusher. Its characteristic is.

Several kinds of jaw crusher development overview and analysis of information industry market analysis

The 11.1 model e 1858 Eli Blake ( E1.Blake ) patented, making double toggle plate of crusher, now the most commonly used jaw crusher is a constitution of jaw crusher and more modern manufacturing of single toggle jaw crusher. The jaw crusher is one of the biggest weakness in one working cycle only half the time for work, since the nineteen eighties, rhyme inner jaw crusher design and improvement achieved certain results. As our broken expert Professor Wang Hongzhu and his students master Ding Peihong cited the dynamic meshing angle of the concept, the development of GXUE series deep cavity jaw crusher, the rise in domestic certain sensation. The machine with the same specifications crusher compared, at the same condition, processing capacity can be increased by 20% 25%, service of tooth plate can be increased by 12 times. The machine adopts negative zero hanging weight having a hyperboloidal cavity second generation GXl250X400 negative in the first generation on the basis of the comprehensive improvement, increases the crushing ratio, reduces the product size, maximum feed size is 220mm, output is 5 16t/h, discharge outlet adjustment range is 10 40mm, feeding the compressive strength less than 300MPa. PEY4060 hydraulic insurance jaw crusher,.

American EW Blake invented the Blake jaw crusher, has a history of over 140 years. As technology advances, the jaw crusher ‘s structure is also constantly upgrading. The jaw crusher has the advantages of simple structure, easy manufacture, reliable work, convenient repair and use and has been widely used in mining, smelting, building materials, highway, railway, water and chemical industry. Jaw crusher market scope is broad, therefore a lot of mining equipment manufacturers choose to jaw crusher most of its main production equipment, but because the technological level and production capacity of the gap, the domestic jaw crusher technical level is uneven, the majority of manufacturers with advanced international standards gap. Obviously a bit is the home of jaw crusher machine weight was generally higher than that of foreign same specifications crusher. The frame for a large proportion of the quality of the whole machine ( casting frame 50%, welding machine 30%). Foreign jaw crusher are welded frame, even moving jaw also adopts a welding structure. Jaw crusher with welded machine frame is the direction of development. The structure design of jaw crusher frame unreasonable example many, enough strength, stiffness requirements of the conditions, reduce the quality. In addition, should be the reason.
