Introduction
Pengfei roller press grinding technology has rapidly expanded from the cement industry to the mining industry, and the market demand space for roller press in the mining industry is worth looking forward to. In the field of mining, roller press can replace cone crusher or ball mill, mainly used in pre grinding of iron ore and non-ferrous metal beneficiation, and has obvious advantages of energy saving and efficiency. With the continuous improvement of mining resources and production capacity development, it is estimated that from 2011 to 2015, the new demand for roller press in iron ore and non-ferrous metal industry will reach 10 billion yuan to 28 billion yuan, and the demand scale brought by technological transformation of mineral processing industry is about 5 billion yuan.Description of roller press
Roller press is the pre grinding equipment of grinding system in the fields of cement and mine. It has the advantages of reducing power consumption, increasing output, saving investment and simple operation and maintenance. Its advantages of energy saving, environmental protection and convenient development towards large-scale are unanimously recognized by the industry. With the implementation of national energy conservation and emission reduction policies, roller press is widely used in cement industry, especially in the field of mining. The roller press adopts the roller press based on the material layer grinding technology in the grinding system and the matching powder concentrator which integrates breaking, grading and drying. It can cooperate with the ball mill or form a self-contained system to form a variety of technological processes, such as pre grinding, mixed grinding, semi-final grinding and final grinding systems. Due to the change of grinding mechanism, "Pengfei" roller press and its system technology can reduce the power consumption of grinding system by 20-50% and increase the output by 30-70%.Application
In the field of mining, roller press is mainly used to replace cone crusher for fine crushing or ball mill for coarse crushing. Due to the high technical content of the roller press in the mine, the enterprise needs to have strong independent R & D and innovation ability. Pengfei group is committed to providing the best solution of grinding system for cement, mining and other fields, "Pengfei" roller press grinding technology has rapidly expanded from the cement industry to the mining field, making a breakthrough growth in the application of the mining industry.Technical characteristics
Wear resistance of roller surface material is the key factor to determine the application of roller press. With the continuous breakthrough of wear resistance of roller surface material, roller press is gradually expanding from the field of cement grinding to the field of various metal ore grinding. In the field of cement clinker grinding, the proportion of roller press application is about 20%. In the field of mine grinding, the roller press application is just in its infancy. The ore grinding of nearly ten thousand metal mines and metallurgical enterprises in China is the key demand of roller press sales for a long time in the future, and the high-pressure roller mill will be widely used in the mine field. Roller press has obvious advantages in energy saving, consumption reduction and efficiency improvement, which is superior to the traditional production process. Compared with the traditional crusher, the roller press can save 20% - 50% of the power, with obvious energy-saving effect; increase the output by 30% - 70%, improve the production efficiency of the system; save the civil engineering investment, facilitate the transformation of the original grinding system, and facilitate the development of the enterprise to the large-scale direction.Advantages of high pressure roller mill
Flexible configuration: the process system has flexible configuration and strong adaptability. Large crushing ratio: iron ore ≤ 60mm can be crushed to ≤ 3mm. Roll surface wear resistance: high hardness, strong wear resistance and long service life. Large processing capacity: the single processing capacity of high-pressure roller mill reaches 50-2500t / h. Environmental protection and high efficiency: the equipment has low noise, less dust pollution, stable roller operation, and effective utilization rate of more than 95%. Saving power consumption: the ultra-fine crushing process of high-pressure roller mill replaces the traditional crushing grinding process, reducing the total power consumption by more than 50%. Reduction of steel consumption: the ultra-fine crushing process of high pressure roller mill replaces the traditional crushing grinding process, and the total steel consumption is reduced by more than 40%. Wide application: the high-pressure roller mill based on the principle of bed grinding is an ideal equipment for energy saving and consumption reduction, which is conducive to the development of large-scale, high-efficiency, energy-saving and automation of beneficiation technology, and has become the main equipment of ore grinding and grinding system.Characteristic contrast
Compared with the traditional process, the ultra-fine crushing of ore can greatly save the power and steel consumption. The crushing ratio is large, the single unit processing capacity is large, the product particle size distribution is wider, and the fine powder is more. It can effectively improve the recovery rate of extremely poor iron ore and the quality of iron coarse powder. The dynamic rotation rate is high, the operation cost is low, and the production cost is obviously reduced. Compared with the wet mill, the unit power consumption is greatly reduced and greatly increased Adding the specific surface area of iron concentrate, effectively improving the fineness and pelletizing quality of iron concentrate, significantly improving the production capacity, high operation rate, low operation cost, significantly reducing production costs, metal ore dissociation, selective grinding, bed grinding technology to try to squeeze lean ore, greatly improving the recovery rate, a large number of microcracks to promote the entry of leaching liquid and mineral dissociation, which is conducive to gravity separation or flotation Pre dissociation target minerals.Quick Inquiry
