Cone crusher is a promising crushing machine. In recent years, the intensity of mine exploitation gradually increases. In the mineral resources exploitation, the most critical is the ore crushing, and processing the finished ore for metallurgy, construction, chemical and other industries. Along with the national construction expands the domestic demand and infrastructure construction increases, we have a large demand on the sand and stone, and the related crushing machinery. The market prospect of cone crusher is broad.
Facing the great need, cone crusher should adapt to the market development demand. Otherwise, it will be eliminated. The market need the high-quality and intelligent cone crusher. So we must make effort to create and develop. Cone crusher is looking forward to the intelligent development, in order to enter the high-end equipment stage. With its unique performance and features, its application will be wider.
Hydraulic cone crusher is an advanced crusher with high power, large crushing ratio, and high productivity. The use range is wide. Especially, it is suitable for crushing hard rock, ore, slag, refractory material etc.. Cone crusher is composed of frame body, adjusting device, regulating sleeve, crushing cone, transmission and eccentric sleeve and other major parts, and electric and lubrication and other auxiliary parts. The machine is divided into coarse cone crusher, middle cone crusher and fine cone crusher.
Cone crusher has the greater operating efficiency and the crushing capacity. It is helpful to economic sustainable development and progress. The advantages design and the superior performance of cone crusher are the fundamental reason why cone crusher has a very large application in the crushing industry. China's cone crusher and other machinery manufacturing industry are very extensive, including mines, construction, water conservancy, metallurgy, mine and glass and other industries. In China, the most important application field is the cement industry, roads and mines. Crusher applied in this several industrial is accounted for about 31% of the entire industry.
The cone crusher with more intelligent needs to have the modernization appearance design, higher breaking force and stronger structure. In addition, in the aspect of human-computer interaction, automatic control, test execution and humanization, it will have greater progress and improvement.
Cone Crusher Difference Home And Abroad
Cone crusher is often used as the two stages and three stages crushing equipment for sand and gravel. It is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industry and many other departments. Now, cone crusher has been the main crushing equipment. Many customers are full of enthusiasm about the foreign cone crusher. Today, we will analysis the difference of cone crusher at home and abroad.
The use performance of the cone crusher is mainly reflected in 3 aspects: allowing the feed particle size, processing capacity and the discharge granularity. At present, compared with the international advanced level, the domestic market of spring cone type crushing machine performance differences have mainly small feeding, large discharge, low processing ability and heavy machine aspects. The main cause is the backward design philosophy.
Our country introduces many types cone crusher from foreign countries. So far although we have many improvements, the main structure is basically no big change. Therefore, in the aspects of cavity design, dynamics and kinematics design, transport lags, we are behind the international advanced level.
Backward design is mainly manifested in the mechanism to realize the laminating crushing degree. In 1950s, laboratory tests prove that, for the single particle material crushing and multi particle material crushing, the laminating crushing can get rid of relying entirely on the row ore mouth to control the material grain grade situation. Then, we can achieve the goal of greater feed size, smaller nesting grain and large processing capacity. Therefore, the advanced design is possible to create conditions for the laminating crushing. Using cavity shape design and increasing the crushing force are the effective measure.
The wear resistance refers to the service life of cone crusher and the customers’ economic benefit. So the wear resistance is very important for cone crusher. The abrasion resistant materials, heat treatment process and other aspects, there are not a small gap between domestic and foreign. Therefore the manufacturing processes of these parts still have deficiencies. The wear resistance is lower than foreign cone crusher.
