After more than 100 years of practice and improvement, the jaw crusher has no breakthrough changes in structure, but it still has the characteristics of simple structure, reliable operation, easy production, convenient maintenance, low equipment and production costs, etc. Widely used in mineral processing, building materials, silicate and chemical industrial production. It is generally used for coarse and medium crushing of hard or medium-hard ores in the mineral processing industry, and is sometimes used for subsequent crushing in other industrial sectors and small-scale mine production.

The production of jaw crusher in my country has only a few decades of history. In the early days of liberation, due to the weak foundation of the machinery industry, the imitation of small and medium-sized jaw crushers was the mainstay. In the late 1950s, due to the development needs of my country’s mining and building materials industry, the design and manufacture of large double toggle jaw crushers were promoted. By the 1970s, the production of jaw crushers in my country had begun to take shape, and the specifications and models were gradually complete, which could basically meet the needs of national economic construction. In the 1980s, due to the adoption of new technologies, the production of jaw crushers in my country reached a high level, which not only met domestic needs, but also began to be exported to Southeast Asia. However, compared with the advanced level outside the circle, the structure and crushing cavity shape of the domestic jaw crusher are still relatively backward. Over the past 10 years, with the continuous innovation and transformation of jaw crushers, the variety and specifications have increased, and it has gradually approached the advanced foreign level.
