Mining machinery is a highly technical and highly integrated equipment. The development of new equipment continues to integrate human achievements in various fields. With the advancement of materials science, manufacturing technology, information technology and computer technology, every round of products has New technology injection, component renewal cycle is getting shorter and shorter, new equipment replacement is getting faster and faster, especially the development of large mining machinery, no mature experience can be used for reference, but it does not allow any mistakes in the design, so it must be With the integration of multidisciplinary technologies, design efficiency and design quality will be improved, and the independent innovation capability and market competitiveness of enterprises will be enhanced. On the basis of the integration of mining machinery, computer technology and network technology, a digital development trend has been formed.
Recalling the development history of crushers, mainly jaw crushers, impact crushers, cone crushers, hammer crushers, ultra-fine crushers, internal channel crushers, counter-roll crushers, impact crushers, etc. . There are many types of crushers, so the name is also different. The vertical crusher (the main shaft is vertical) has been a hot crusher since it was introduced in the 1980s. As a fine crusher, the average discharge size is ≤3~4mm, 90% is fine powder. In order to reduce the particle size of the ball mill, the yield is increased by 20% to 30%. After more than 20 years of development and evolution, the vertical crusher has evolved from a single blow to a shock-back crusher from the first to the fifth generation. The service life of the hammer is more than four times higher than that of the old crusher. The vertical shaft impact crusher, which is a representative product of vertical crusher, is widely used in the fine crushing of iron ore, gold, cement, glass, ceramics, electric power and steel industries. However, if you choose a vertical crusher for the crushing of road construction materials, it is a wrong selection. This will use the horizontal crusher we will talk about below. Nowadays, the vertical crusher has developed into the current Dawn Heavy Industry 5X series high-efficiency impact crusher. It is a perfect combination of professional crushing technology and mechanical manufacturing, and is a full embodiment of new technologies and new processes. The 5X series vertical crusher can not only provide the highest quality sand and gravel aggregate for highways, high-speed railways, high-rise buildings, municipal works, hydropower dam construction, port terminals, concrete mixing stations, etc., but undoubtedly become the mechanism sand industry and The core equipment in the field of stone shaping; and more and more become the mainstream equipment in the fields of metal ore crushing, quartz sand production, steel slag treatment.
Crusher is an important indicator to measure the strength of mining machinery manufacturing
According to the national industrial policy of supporting the development of basic industries such as energy, transportation and raw materials, mining machinery as the pillar of these basic industries should receive priority support from the state for further development and improvement for the development of coal, metal and non-metal mines. Provide more high-quality, high-efficiency crushers, mills and sand making machines with international advanced level to meet the needs of energy and raw materials for national economic development. Mining machinery mainly includes crusher, sand making machine and milling machine. The crushing machine is the most important part of the whole ore crushing process, and also an important indicator to measure the strength of mining machinery manufacturing.
