Gold ore crusher revolving speed affects ore beneficiation

The gold ore crusher, as a grinding machine, is regarded as the essential auxiliary equipment in the ore beneficiation production line. For a gold ore crusher, the revolving speed has much effect on the equipment performance, productivity as well as its service life. Therefore, the gold ore crushers revolving speed also plays an important role in the normal ore dressing plant. To increase the revolving speed in a proper range will improve the working efficiency of the gold ore crusher to some extent. However, we should not take it for granted that the faster the gold ore crusher runs, the better because too high revolving speed will result in a lot of problems to the gold ore crusher. The current gold ore crushers can change their revolving speed through the reducer and the speed generally is lower than that of the electric motor. If the gold ore crusher revolves at a high speed or super high speed, it will not only lose the normal grinding function as a mill because of the eccentric force, but also experiences strong vibration and serious wear problems, thus shortening the gold ore crushers service life. What’s more, too high revolving speed will damage the normal grinding function of the gold ore crusher and widen the discharging port of the equipment, thus causing too much load for the classifier and making finished products own unqualified grain size. At the same time, if the gold ore crusher revolves too fast, it will enlarge the consumption quantity of the lining plate and steel balls. Above all, we may learn much about the importance of the gold ore crushers normal revolving speed in the ore beneficiation production line.

Approaches to improve the performance of ore milling equipment

With the rapid development of highway construction cause, mechanical construction is overwhelmingly dominant in the road construction. The pros and cons of the performance of ore milling equipment greatly restrict the quality, progress and cost of the highway project. During the usage of the mechanical equipment, the pros and cons of the mechanical equipment is directly influenced by the three factors: human being, machine and environment. In order to improve the performance of mechanical equipment, you have to strengthen the management of the human being, machine and environment. The fundamental way for improving the performance of ore milling equipment is to strengthen the humanity management. Since the constant development of the scientific technology and the extensive usage of the new technology, new material and new process, the demands for the mechanical operators is relatively higher because of its various function and complicated structure. Therefore, it is essential to enhance the skills training of operating personnel in order to make them master the principle, performance, composition and operating skills and grasp the abilities of faster fault diagnosis and maintenance skills.

Import and export situation of ultrafine mill equipment

With the healthy development of the domestic economy, ultrafine mill equipment market is more popular. The output value of ultrafine mill can increase about ten billion average annual; the market share in domestic is also higher and higher. For a long period of time, due to the domestic producers have not mastered the technology to design and manufacture large-scale and high-end ultrafine mill equipment, the market share of foreign equipment in the domestic market is relatively high. However, with the more and more emphasis on research and investment in technology in the past few years, the quality of China's ultrafine mill products has obvious changes. There have emerged a large number of large scaled and advanced products with the independent intellectual property rights which greatly narrow the technological gap with the advanced countries. With the accumulated experiences and the support of the national policy, we can compete with the advanced country in the international trade by virtue of the price, service and the quality. Because of the above reasons, China's ultrafine mill products have appeared gratifying situation of trade surplus. The dependence of import equipment of China ultrafine mill market is more and more small. In the further development process, the general trend of ultrafine mill industry is that the exports will further expand, while imports will gradually decrease, the narrowing trend of import and export deficit will become increasingly evident. But the domestic ultrafine mill should continuously research the new technology. If the mining industry wants to narrow the import and export gap, they must do technical innovation, improve the mineral utilization, and change high pollution and high consumption situation of mineral processing. Only by realizing the qualitative change from the quantitative change can the ultrafine mill industry remain invincible.

Tooth plate structure of ore milling equipment

Tooth plate, which is also called lining board, is the spare that that directly contacts the ores in a crushing machine. In spite of its simple structure, it has influences on the production capacity, energy consumption, product granularity composition and particle shape and the crushing force, especially the last three items. Tooth plate has to sustain huge impact and squeezing force, for this reason, its abrasion is very serious. To extend its service life, we can study from two aspects: first, adopt highly wear resistant materials; second, reasonably design structural shape and physical dimension of tooth shape. The commonly used tooth plate by ore milling equipment is ZGMn13 whose features are that under the impact load, the surface of the materials is hardened, thus forming hard and wear-resisting surface, and at the same time, it can maintain the original tenacity of the inner metal, for this reason, it is a commonly used wear resistant material in ore milling equipment. The main disadvantage of the common high manganese steel is that in the using process, the material will be out of shape. In recent years, the commonly adopted material is high chromium white iron in the domestic and foreign market and its service life is much longer than that of the high manganese steel. To ensure product granularity and shape, it is advisable to choose V-shaped or ladder-shaped lining board.
