Mining machinery is a type of machinery directly used for mineral mining and beneficiation operations. Including mining machinery and mineral processing machinery. The working principle and structure of exploration machinery are mostly the same or similar to the mining machinery used for mining similar minerals. In a broad sense, exploration machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators, and drainage machinery are also used in mining operations

The mining machinery industry is one of the important basic industries that provides equipment for the extraction and processing of solid raw materials, materials, and fuels. It serves important basic industrial sectors such as black and non-ferrous metallurgy, coal, building materials, chemical industry, and nuclear industry. Its products are also widely used in the basic construction of basic sectors such as transportation, railways, construction, water and hydropower.

The mining machinery industry in China mainly consists of seven categories, with over 300 varieties and thousands of specifications of products. Since 2000, driven by the rapid development of domestic basic industry and infrastructure, the demand for mining machinery products in the market has been strong. In 2010, the sales revenue of China's mining machinery industry exceeded 400 billion yuan. As a result, China has surpassed North America, Japan, and Western Europe to become the world's largest mining machinery market.

The mining machinery industry holds a pillar position in the national economy and plays a significant role and contribution in economic construction. Whether viewed from the current market development status of China's mining machinery industry or the global industry operation trend, China's mining machinery industry is in a historic window period. The next 5-10 years will be an important period for Chinese mining machinery enterprises to fully or deeply integrate into the world and develop together with the world, with good prospects for the development of the industry. It is expected that by the end of the 12th Five Year Plan period, the sales scale of China's mining machinery industry will reach 900 billion yuan, and the export value will exceed 26 billion US dollars.

The crushing operation is often divided into coarse crushing, medium crushing, and fine crushing according to the particle size of the feeding and discharging materials. The commonly used sand and gravel equipment includes jaw crushers, impact crushers, composite crushers, single stage hammer crushers, vertical crushers, rotary crushers, cone crushers, roller crushers, double roller crushers, two in one crushers, and one-time forming crushers.
