JinJin machine Co., LTD, is a collection of r &d, production, sales as one of the modernization of the mine equipment enterprises. DuoNian to JinJin committed to the design, production and other modern mining equipment, crusher and widely used in electric power, metallurgy, mine, dock, granaries, chemical industry, etc. Products all over the world, and sold in Europe, America, Asia, Africa and other international market, praised by users.
From abroad on th century began using computer simulation technology for crusher institutions, cavity type, production and wear of the optimization, which greatly improve the performance of the crusher, shortened product development cycle, improve the market competitiveness of products. Although home also has scientific research workers began to try to use of the advanced kinematics and dynamics simulation design tools for a rapid development of crusher, mechanism design parameters of the simulation optimization design, so as to reduce the workload of the simulation design, shortened product development cycle, improved the simulation model reusing rate. Yet domestic to the simulation optimization design of the crusher is mainly limited to specific types of research of the crusher write corresponding program optimization design, these programs mostly poor, reuse can only solve specific types of specific problem. To shorten the gap in the same period, catch up with international cement, it is still a longer process. To jaw crusher manufacturing for example. Our country jaw crusher movement method of four connecting rod mechanism design theory has great progress on the same period, and close to the international level. But jaw crusher crushing cavity two-way tooth Angle, short cubits board angular, reduce the transmission Angle and eccentricity, foreign companies offer products already often use these validated advanced design theory to improve product performance and reliability in use. Our domestic manufacturers for a variety of reasons the advanced design theory, the main products of little almost all of the 1970 s to finalize the design product, the before wear-resistant materials (such as high manganese steel) and important fittings (such as spherical roller bearing), and other domestic foundation, a service life below the international advanced level of the same kind product. In addition, the main processing and assembly process also and abroad have a big gap.
Cause the objective cause many domestic and foreign gap, these reasons and not "theory and the technology behind" can sum up.
The market demand of different objective reason is not allow to ignore. On the international market, excellent and crushing equipment manufacturers in Europe and the concentration, the market need and crushing equipment specifications, highly automated, mobility is strong. And our country is in the large-scale capital construction period, but mount quickly, less investment, in short supply market led directly to the rough way, technical level is low, high energy consumption and environmental pollution in the product into serious.
The objective cause not short time to catch up, but the gap between the technology can be through the technology introduction, digestion absorption, the independent innovation, quickly to the world of high-end mobile crushing industry.
Although both at home and abroad have certain gap, but to cement enterprise speaking to choose enterprise production line, the crusher gain maximun benefits is the most important. The emphasis of the crusher of of all kinds, adapt to different conditions is different also, and the size of the production line is different, need model is different also, so must be strict selection, crusher selection.
Although specific models need to actual working conditions of to decide, but can still through all kinds of crusher its technical superiority to select a specific type. For example: the place for a hammer crusher has fixed sieve, users can need according to oneself chooses appropriate aperture sieve to control the grain-size; The impact breaker the grain-size even, the material is a cube, fine powder and shape dust content is low, especially suitable for vertical mill operation.
Finally, cement manufacturers choose cement clinker finely unit, consider the following Suggestions: hammer work principle of linear slow, durable, high rates of; The machine material narrow particle size distribution and stable, be helpful for grinding machine for the ball with the optimizing level; Low power consumption, low cost of accessories; Structural design is reasonable, processing creation is fine; Accessories convenient maintenance; Avoid metal on the machines, need to install in addition to iron and metal detector.
