15 July, 2012Has overcome the defect of easy-vibration and easy-abrasion, the vertical mill has gradually become the principal force of processing micro slag powders. The specific surface area of the micro slag processed by this machine is 420~450m2/kg which greatly satisfies the demands of the customers.
12 July, 2012In 2012, the GDP growth is expected to target in 7.5% but it does not mean that our government will reduce the investment in infrastructure construction. The United States currently is still not out of the financial crisis and debt crisis in Europe continues to ferment, the entire world is looking forward to seeing China drive the development of international economy.
10 July, 2012The rapid development of China’s GDP does not mean that our state will reduce investment in infrastructure construction. On a global scale, China’s rapid economic development is also desirable.
08 July, 2012With the constant development of science and technology, cement has been one of the major building materials in human construction and been widely used in the industry, agriculture, water conservancy, transportation, electric power, technology and urban.
05 July, 2012The newly developed Hongxing Sand Making Machine takes advantage of the strengths of reaction crusher, impact crusher, cone crusher and hammer crusher . And it exploits the crushing principle of stones-crush-stones, replaces the property of Vertical Crushing Machine and realizes operation with high productivity, high quality and low cost.
03 July, 2012As the most common material and valuable non-renewable resources, the ore processed by the crushing machine or stone production line will be applied to various field.
01 July, 2012The ball mill designed special for cement paste is the key factor of ensuring the quality of cement paste and realizing cement paste production upsizing. At present, there is no such modular cement paste ball mill at home and abroad so that many countries have been constantly researching and exploring.
28 June, 2012According to the whole process of theory and research about vibrating screen, we can find out the following problems existing in the research of vibrating screen:
27 June, 2012The two stages of rock breaking and grindings are the most composing part of all the other operations in the ore beneficiation plants so that they are highly valued and emphasized.
24 June, 2012The flotation with the advantages of high concentration ratio, high recovery ratio, low cost and easy to control is suitable for dealing with the fine particles. Through several years’ research and develop, the flotation has been widely accepted all around the world to separate various ores and coal.
22 June, 2012The rotary speed of ball mill directly determines the state of motion of the cylinder body of the grinding media and grinding operations effects. The lifting height of the balls in the ball mill is small when the speed is low. Because the gravity of the balls themselves, balls fall from the top as spilling off the state.
20 June, 2012During the working process of the jaw crusher, the rotary of cam gear drives the plunger type injection pump to supply high pressure oil to the system. The oil pressure of the system will be determined by the rating nut of the oil pressure adjusting gear according the biggest crushing force allowed for the crusher.
17 June, 2012The production of ore dressing is a complex process, with the transition and transformation of substance and energy. It has the characteristics of time-variation, large lag, complex mechanism and lots of affecting factors, with the performance of consecution in large range, nonlinearity and tight coupling, which is complex and indeterminate.
15 June, 2012When the sand maker is working, the possible reasons why the bearing becomes warm are lack of oil, dust in the machine and damage of the bearing. The elimination methods are to add oil or cleanse the bearing and change new bearing. After the fine crushing of the sand maker and the drying process of the dryer machine, the grinding mill also plays an important role, so that the correct operation of the grinding mill is also important.
12 June, 2012The selection standard of proper crushing equipment includes selection according to the difference of the hardness of all kinds of rocks, and according to the requirements for the shape, granularity and uniformity of fineness of the crushing products.
06 June, 2012Usually it’s in the form of copper metal and copper alloys. Copper ore is kind of very important metal materials to the national economic construction. It is generally believed that the number of copper mine consumption and uses often reflects the level of a country's industrialization.
04 June, 2012The lubricating oil goes into the cone crusher by two paths. One goes in from the bottom oil hole of cone crusher, and then divides into three directions to the inside and outside of the hollow eccentric shaft, the middle oil hole of the main bearing and the bowl type bearing, going through the hole lubricating big and small gear, and then the oil will return from the bottom oil returning hole of the small bevel gear.
03 June, 2012Generally speaking, the crushers are used to crush the stones. If the hardness of the materials is not very high, a relatively low-grade crusher can be chosen; if the hardness is a little comparably high, a crusher of high quality can be chosen.
02 June, 2012The crushes are widely used in mining, smelting, materials-building, road-building, water conservancy and chemistry and other industries, whose development is depended on by the fast development of economy.
01 June, 2012It is becoming more and more important for mining machinery manufacturing companies to research and develop new types of grinding machines during the grinding operation process and developing large sized, energy-saving and fine and super fine grinding mills is a developing tendency of the grinding machines.
