Today, the quality of air quality is a common concern of all countries, and the universality of automobiles undoubtedly makes environmental pollution even worse. Therefore, how to reduce the vehicle's equipment quality as far as possible, ensure the vehicle's strength and safety performance, reduce the fuel consumption, and thus reduce the exhaust pollution has become the common goal.
Because the quality of conventional car preparation is relatively high, it cannot be overestimated when people hear “lightweightâ€. The so-called "lightweight" does not mean to "cut corners, but to optimize the body structure and enhance the strength of materials. Do not look at just such a few words, but its difficulty is not unusual. Why do you say that?
Currently, automobiles rely mainly on aluminum alloys, glass fiber reinforced plastic (GFRP) and carbon fiber (CFRP) materials to achieve "lightweight" automobiles. Although aluminum alloy car bodies can theoretically achieve a 30% to 40% weight reduction compared to steel car bodies, the glass fiber and carbon fiber can achieve a higher proportion of lighter weight, but these materials are not only limited by the processing technology, but also by the supply chain. It is also quite small, which leads to high costs, and the number of car companies willing to try is very small.
In addition, the manufacturing cost after the implementation of "lightweight" technology is also quite high. Take the body structure, in order to improve the car's "lightweight", we must increase the proportion of aluminum alloy material in the body structure, so that new problems arise, due to the difference between the melting point of aluminum and steel too much , welding together is easy to crack. Engineers are concerned that using traditional methods of riveting or gluing will pose a threat to the safety of people on the vehicle, so they have developed aluminum spot welding technology and achieved fusion welding between aluminum alloy and steel, which has greatly improved the safety of vehicles. . The cost of this technology is also quite high, so it is not possible to apply to all models, but this is only one aspect of “lightweightâ€. If all the items are added together, how difficult it is to imagine Big.
Therefore, we should treat "lightweight" with a fair attitude, because it is really not an easy task.
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
