The jaw crusher has developed for many years. Now it is widely used in many industries and has a very advanced technology.Jaw crusher has experienced more than 100 years, although nothing groundbreaking changes in the structure, but because it has a simple structure, easy to produce, easy maintenance, equipment and production costs low, so until now Jaw crusher is still widely used in the production of mineral processing, building materials, silicate and chemical industry. It is generally used in the mineral processing industry production thick, hard and medium hard ore crushed, sometimes in the production of other industrial sectors and small ore crushing role.Jaw crusher production is only a few decades old. The early years of the People"s Republic of China, mainly due to the weak foundation of Machinery Industry, the imitation of small and medium-sized jaw crusher, the end of the 1950s, due to the development needs of our mines and building materials industry, promote on the large elbows board Jaw crusher design and manufacturing. 1970s, our jaw crusher production has begun to take shape gradually complete specifications, can basically meet the needs of national economic construction.In the 1980s, due to the introduction of new technology, so that our jaw crusher production reached a high level, not only to meet domestic needs, but also are exported to Southeast Asia, but compared with foreign advanced level, domestic jaw crusher structure and crushing cavity is still relatively backward. Over the past 10 years, with the jaw crusher, continuous innovation and transformation, an increase of varieties and specifications, has gradually approaches the advanced level.At present, China"s production of the most widely used jaw crusher There are two types: the moving jaw to do simple swing jaw crusher crank double rocker mechanism - simple pendulum-type jaw crusher; movable jaw complex swing crank rocker mechanism jaw crusher - compound pendulum type jaw...
