The domestic and foreign research status of vibration grinding machine

Number of visits: Date:2015-04-28
The vibration mill is a new type of grinding equipment of an efficient, energy saving, metallurgy, chemical industry, mainly to solve the non metallic minerals, medicine, ceramics, cement, new building materials, magnetic materials and other industries of superfine powder processing problem. Because of ultra fine powder or superfine, atoms or molecules with the metastable state in thermodynamics, the area ratio increases, which character is more lively, changes in the optical, electrical, magnetic, thermal and chemical activity, and more superior in the use of the effect. These changes not only does not belong to solid state physics is not atomic and molecular physics, physics is a new subject, the formation of ultra fine powder of physics characteristic. Modern science and technology, often need to powder fine particle size to 500 ~ 12500, and some even need with micron or nanometer particle size, this is the ancient tradition of crushing technology and equipment can not be achieved. At present many colleges and universities, scientific research institutions have super fine or superfine powder as the main direction of research and development, will focus on how to get more fine crushing technology and equipment.
1, the domestic research status of vibration mill
Grinding equipment in China: ball mill, Raymond mill, grinding, mixing mill, roller mill and column mill etc.. At present, China is still the dominant mill ball mill cement, ceramics and other industries. These devices have many advantages, but also has its own weakness. For example, by the technology and processing characteristics of the mill itself, are unable to process high hardness, fly ash and slag with high hardness and non metal materials, especially the ball there is noise, high energy consumption, environmental pollution and other shortcomings, can not meet the production of powder fineness of high grade cement, high-grade ceramic products and other new building materials required.
Large multi-purpose ultrafine vibration grinding machine, grinding process from the structure, shape and the principle and the traditional mill is fundamentally different, it is the use of mechanical vibration theory, the machine can work in low energy consumption, thereby reducing in the process of superfine powder, large power consumption of material crushing required. This technology can be said to be a revolution to the traditional grinding technology, more suitable for brittle material of high hardness to do fine, super fine powder processing. At the same time, with low noise, low energy consumption, no pollution to environment etc..
Due to historical reasons, China began in the early sixty's research in this area, but due to the large vibration mill still exist many technical problems in the design and production, such as supporting the spring, the rigidity of the whole life of the grinding body and connection strength, bonding strength, wear-resistant materials, and the lack of supporting parts and the corresponding design standards and other reasons, the slow progress of the study. In the mid eighty's, only Wenzhou mining machinery factory production of small vibration mill. Later, after a Henan Eastern Xinxiang mining equipment factory, Yantai Zhuoyue mechanical transmission Co. Ltd., Luoyang Mining Research Institute, Wuhan University, Xi'an University Of Architecture And Technology and other units of the production of the vibration mill.
However, the development of common units vibration mill production problem is a small amount of processing, large-scale industrial production process is not ideal, the pollution of iron impurity in raw material grinding process. The superfine powder in processing, grading, decontamination, purification and surface modification of still exist many technical problems, making the superfine powder processing technology and equipment, the long lags behind that of developed countries. Many products because of raw material and manufacturing process there is a certain gap with foreign body, causing the processing quality of superfine powder of decades of stagnant, especially in the field of cement, building materials, ceramics, paint, paint and other difficult to enter the market, product quality and manufacturing technology leading ranks.
To promote the development of a new generation of energy-saving vibration grinding equipment, not only can fill the vacancy of superfine powder processing equipment industry, and to accelerate the technological transformation of enterprises and give full play to the old equipment, the processing capacity of the new technology and equipment, increase the market competition ability of the product.
In 2, the foreign vibration grinding machine research and development
Germany is a vibration mill developed earlier countries.
At the beginning of the forty's, although Hochst is studied systematically on the vibration mill, but it was not until the late fifty's, PALLA series vibrating mill development of Germany Klockner-Humboldt-Deutz company became widely popular in European countries styling products. Since the seventy's, the German National Research Department has been the preparation of superfine powder technology as a special research field (Sonderforxchungbereich) treatment, and to ClaustablBraunschweig KHDAlpine University and industry company as the center to form a study group. According to the data, the vibration mill is Lurge company produces varieties complete, matching process of grinding cylinder, the effective volume of 60 ~ 2500L, which can meet the demand of different processing. But because the German in the equipment manufacturing process of material selection and process of more sophisticated, high standards, vibration grinding body uses the rubber compound spring support, so that the high production costs, sales difficult to developing countries.
The vibration mill manufacturing central Japan chemical machinery, heavy industry, Kawasaki work products company, is a single cylinder grinding technology at the beginning of the sixty's from Germany SIEBTECHNIK company introduced, then they are research and development independently. At present, Japan is not only the production batch, also can produce continuous and horizontal eddy current vibration mill, both in the production quantity, type, technical performance, theoretical research and new development are very advanced, very high reputation in the market, and to declare the many patents
