In 40 years ago, on the GoerTek Limoges international processing conference, someone is put forward for the first time, According to the technical standards of that time, crushing the grain size of grinding can reach 6`8mm. At present, China has built large-scale mines, mostly reached such as grinding particle size is about 8mm, saving a lot of energy.
Large mine mostly uses three section of a closed-circuit crushing process. In the coarse, medium and fine crushing technology, closed-circuit fine crusher is the key to realize more broken less grinding equipment. At present, the mainstream of finely machine is the choice of cone crusher there are many different kinds of selection of cone crusher, how they evolved?
The origin of the cone crusher is spring cone crusher, hydraulic cone crusher has developed later, and there are many different kinds of hydraulic cone crusher, and what of the evolution of hydraulic cone crusher?
1) In 20th 40s, the company launched the first American bottom single cylinder hydraulic cone crusher, using hydraulic technology, has realized the hydraulic adjusting row ore mouth and overload protection. Simplified the structure of the crusher and reduced the weight, improved the performance of use. This kind of machine because it depends on the size of the discharging mouth size control product granularity, the product particle size is not uniform, and the water, the material containing mud blocking.
2) In20th50-60s: The companies of France and Japan launched around the upper platform of cone crusher yiji9 platform of cone crusher.
3) In 20th70-80s: Some companies in the United States on the basis of the single-cylinder hydraulic cone crusher with high-energy hydraulic cone crusher.
SBM crushing machine above unremitting efforts in R & D hydraulic cone type successfully developed the HCS series horizontal hydraulic cone crusher and HPC multi-cylinder hydraulic cone crusher.
In future development, company will continually work hard, On the basis of digesting and absorbing foreign advanced technology, its localization, achieve a breakthrough and innovation in technology. For the future introduction of crusher and the development of domestic crusher industry provide valuable experience.
