Comparison and analysis of new HJ jaw crusher and traditional crusher
The 21st century is a period of rapid development. It is a period in which high output is constantly replacing low output equipment, and low energy consumption is replacing high energy consumption equipment. In short, new equipment is constantly replacing traditional equipment, and fast fish eat slow fish. Today, with the rapid development of mining machinery, mining machinery and equipment are also constantly updated, integrated and innovated. Only in this way can the mining demand be met and the products demanded by customers be manufactured.
The development and improvement of jaw crusher has made certain achievements in the development process of recent decades. The machine equipment is designed with negative support and zero suspension, which has the structure of hyperboloid cavity, and the processing capacity and working efficiency of the equipment are relatively high.
Shortcomings and Defects in Crushing Technology of Traditional Jaw Crusher
(1) Single crushing process: multi-functional crushing cannot be realized. In the working process, if the properties of materials to be crushed are multiple, the traditional crushing process cannot completely separate them, and the materials are prone to be over crushed. This kind of over crushing reduces the useful ingredients and forms waste products in crushing operation, resulting in waste of resources.
(2) Backward process level: it is very difficult for the current jaw crusher to achieve ultra-fine crushing under the technical and technological conditions. We need to go through multiple stages of operation to achieve crushing. Because the equipment is relatively large and bulky as a whole, it needs to occupy a large area and space in the installation process, as well as a solid support foundation.
(3) Large energy consumption: when the crushing compressive strength limit reaches a certain level, the crushing equipment will consume a large amount of energy but cannot achieve the crushing effect of ideas. The energy consumption, such as power consumption and steel consumption, is large and cannot effectively achieve the energy-saving effect.
More and more mines have begun to use mechanized operations to improve the mining rate of mines, especially in coal, copper, zinc mines and other mines, where the degree of mechanization has been greatly improved, and these industries are also increasingly demanding. The shortcomings of jaw crusher can no longer meet the needs of modern mine production, and the products are in urgent need of upgrading.
This is based on these shortcomings. SMMVIK's HJ jaw crusher leaves the factory. The wearing parts are mainly jaw plates and guard plates. The jaw plates are made of high-quality high manganese steel alloy. The hardness and resistance of the materials are improved by adjusting the proportion of carbon steel in the casting process. Secondly, from the structure point of view, the jaw crusher structure mainly includes the overall shape, part shape and the optimization of the assembly design of each part. The shell of the jaw crusher can be cast and welded, and can also be connected by bolts and other ways, so the adaptability of the jaw crusher in the use site has been greatly improved. Optimize the cavity shape, that is, change the section shape of the tooth plate to get a more reasonable curve of the crushing cavity, so that the feeding and discharging can get a better match. Change the suspension height to reduce the positive suspension height, or even to zero or negative suspension, so as to increase the horizontal travel of the lower end of the movable jaw. Later, improve the maintenance system. Jaw crusher has a high breaking strength. Once daily maintenance and servicing cannot keep up with it, it will greatly increase equipment wear and shorten the life of jaw crusher. At present, the jaw crusher, coupled with circulating lubricating oil circuit and cooling system, can effectively reduce equipment wear and reduce the maintenance and maintenance costs of daily production.
As a supplier of mining equipment, we continue to innovate and introduce mining equipment that is more in line with contemporary needs. The new HJ jaw crusher is a sharp ore tool. We welcome investment advice.
