Crushing and grinding technology plays an important role in the development of the national economy, and also it plays a significant role in promoting the development of the society.
Crushing and grinding of material is the necessary link of the solid mineral process, it is the first step of producing industrial raw materials. With the large number of mineral resources exploitation, colored, black and metallurgical mineral resources are increasingly becoming depleted, the amount of mining is greatly increasing, and the amount of needed gravel is rising, which makes crushing operation become more and more important.
According to statistics, by the end of 2010, the total mineral resources of China has proved accounts for about 12% of the world, it ranked the second place in the world, and 171 kinds of minerals have been found. In addition, the steel production, coal production, non-ferrous metal production and cement production in 2009 ranked the first place in the world; this is the tremendous achievements that China has got in the part of mineral resources’ exploration, development and processing.
Comprehensive utilization of mineral resources, technology and industry’s rapid development, not only provide a broad space for the crushing and grinding equipment, like hammer crusher, jaw crusher, and so on, but also put forward higher requirements to them.
Because the bonanza amount continues to reduce, but the lean ore is increasing, which makes the crushing difficulty of materials increased. How effectively separate the useful minerals, reduce energy consumption and improve the performance and production efficiency of mining machinery equipment, all these are the common problems that companies is facing.
Take jaw crusher for an example, it is the oldest equipment, its development is obvious. The technological advance of the jaw crusher is mainly reflected in four aspects: structure, cavity type, parameters, and institutions. Through the improvement of the above aspects, they make the key performance parameters of the crusher greatly improved, so the future development of it is also unstoppable.
