To analyze the change of grinding mill consumption per unit of China’s iron ore concentrator from 1986 to 1995, it is easy to see that it dropped O l7 kg / t. Calculated as 246 million tons in 1995 iron ore production for China’s iron ore concentrator ball consumption of steel by 41 860 t. Value of 1.2558 billion yuan. During this period due to the iron ore concentrator emphasis on reducing consumption of steel, generally carried out the testing and promotion of the grinding media, has made great achievements. , Anshan Iron and subordinate concentrator 1986 to 1995 10 years, average ball consumption decreased by 023%; especially Donganshan the concentrator ball consumption decreased most significant, are shown in Table 53-6. To sum up 1981 and 1995, the progress of the grinding media has taken two big step First, forging, casting, heat treatment, a significant reduction in the unit consumption of grinding media; the implementation of low-chromium alloy the low quality of ball gradually out of the market.
10 years in the late 20th century to the early 21st century. A large number of annual handling capacity of below 500 000 t of small iron ore dressing plant growing generally abandoned the concept of grinding media cost-effective, energy saving affect the iron ore concentrator. However, China’s former subordinates focused on iron ore concentrator still insist on the use of high-quality grinding media for many years and new varieties of research, development and promote the use of the dominated. Mainly in the following aspects. Iron ore beneficiation factory of Angang Group mining company Qidashan from the United States with three large grinding equipment, ball mill size of φ5 49 m × 8.83 m ball mill 6, is the nation’s largest mill. Order to reduce the grinding media consumption, further improve the grinding efficiency, Anshan Iron Mine wear-resistant materials, the company developed a low-chromium Alloy cast iron segments, and industrial test in Qi Dashan iron ore beneficiation factory.

Shougang Mining Company over the years for some ball mill has been used billet production of Shougang 97 mm substandard the ordinary φ127m ball. After several improved wear resistance of the ball, but due to poor billet material, the 1998 ball consumption of 0.99 kg / t, nearly l-fold higher than the domestic advanced level. Shougang Corporation for the continuous casting billet rolling process transformation, processing ball materials will be finished billet 97 mm substandard billet is changed to 120 mm, facing the ball prices to rise. In this context, the Shougang Mining Company, organized in the old waterworks concentrator plant bainite ball and ball industrial production and application tests. Bainite ball with ordinary ball, ball consumption decreased by 0 67 kg / t to 0.45 kg / t, lower 0.22 kg, / t,. And did not appear cracked and peeling, with a high hardness, toughness, good wear resistance, and loss of roundness characteristics. In the shape remodeling of grinding media, since we launched rod ball (also known as the column ball capsule ball) in 1983, the rod mill has had a wide range of application in the second and third sections of the iron ore concentrator ball mill. The remodeling of grinding media in China has gone ahead at the international forefront.

The integrated circular vibrating screen mainly consists of the screen box, screen cloth, vibrator and damping spring. The vibrator is mounted on the side panel of the screen box, through belt-driven by the motor rotation, the centrifugal inertia force, forcing the vibration of the screen box. If there are no special requirements, YA, and 2YA type of textile screen surface, YAH-punching the screen surface, can meet all kinds of screen surface. Circular Vibrating Screen is used for resins, paints, industrial chemicals, cosmetics, paints, mining and other wide range of industries. In addition, the nuisance handling a wide range of applications such as waste oil, waste water, dyeing and finishing wastewater, additives, activated carbon characteristics such as industry.
Shaker vibrator screen box, the isolation device, gears and other components, with a rectangular mesh is installed on the screen box, sieve boxes and screens in the role of the vibrator will produce different vibration trajectory, often have round, oval or linear trajectory. Since the vibration of the screen surface to the screen surface material layer loose and toss to leave the screen surface, so that the fine grade material through the whereabouts of the material layer and discharged through the sieve and card vibration of particles in the sieve, with the exception of produce screening effect, and the material forward movement of the vast majority of the applications present in the quarry in a circular vibrating screen, it has a circular trajectory inertial motion, also known as single-axis shaker. Circular trajectory inertial shaker can be used for a variety of screening operations, screen surface materials continue to flip and loose, and have the opportunity to move to the lower material layer when the fine grade material discharged through the sieve. Stuck in the mesh material by vibration and out of, so you can prevent the clogging of the sieve.
Another outstanding performance is high screening efficiency, and the inclination can be changed according to demand, either changes the material velocity along the screen surface, thereby enhancing the handling capacity. Spindle reverse hard screening materials, so that the vibration direction of the opposite direction with the movement of materials to improve the quality of screening. From the appearance point of view, the simple structure compared with other mining equipment, Vibrating Screen, Removable screen surface is convenient. As a result of the cylinder eccentric shaft vibration exciter and partial block help to adjust the amplitude, and easy maintenance. High-quality spring steel woven mesh or punching sieve, so that the equipment and long service life, easy to block the hole. Rubber isolator spring, a long life, low noise, over the resonance region is stable also the advantage of the characteristics of the device is commendable.

The grinding system consists of seven production lines, except the first production line, the other six production lines are identical. The first production line grinding system: The first production line grinding system including: SAG mill (including the feed chute, screen cylinder lubrication system); semi-autogenous mill and ball device; grade flow at the mine pump pool (including guitar frequency conversion to mine pump); classification cyclone Group at once; first magnetic separation; ball mill (including the feed chute, cylindrical sieve, lubrication system); second grade flow to the mine pump pool (including the frequency conversion to the mine pump); grade flow group; secondary magnetic separation; ball mill and ball device; stand mill; third grade flow to the mine pump pool (including the frequency conversion to the mine pump); third grade flow group; three magnetic election; mill stand and ball device.
Broken ore sent to the SAG mill feed chute via the feed belt conveyor installed in the chute on the level detector, when the material level reaches the upper limit set value, will give the computer control system to send alarm signals; material level reaches the high limit setting value, will the computer control system to send chain signal to stop the running of the SAG mill feed belt conveyor. In order to make a half since the mill to maximize grinding efficiency, and ensure the grinding quality, must ensure that the appropriate concentration of the semi-autogenous mill grinding. Humidity of the ore, return the amount of sand and return sand moisture changed little, according to the set in a half since the mill to the Division belt conveyor belt scale to measure the actual amount of ore to determine the semi-autogenous mill to the water Scaling in half since the mill’s water supply valve to adjust the SAG mill pulp density remained constant. SAG mill load, improve the efficiency of the SAG mill grinding, by the power transmitter and load sensors installed in the mill right half from the mill power and fill rate measurement, to measure the actual power and fill the slaughter and expectations compared to adjust the difference between the two semi-autogenous mill ore, to prevent the SAG mill overload or under load the phenomenon, semi-autogenous mill to The amount of ore to adjust the tape transport systems and stockpile.
Through the semi-autogenous mill cylinder screen to screen qualified pulp sent grading cyclone group to the mine pump pool sieve on large pieces of ore from the back to feed tape machine to return to the SAG mill to the ore chute re- grinding. Returning materials on the tape machine to set the speed of the belt conveyor detection, deviation switch, check blocking switch, Pull-wire emergency stop switches to complete the monitoring of the belt conveyor. The control system will provide remote and local are two control modes.

As for the ultrafine ball mill in milling equipment, the fineness of the powder determines the performance of the ball mill accessories. Thus, the qualified ball mill is the mill equipment that can guarantee long-term processing of fine powder. When purchasing milling equipment, customers must be particularly concerned about the fineness of the mill processing.
The fineness of the powders determines the performance of the ball mill, and the qualified ball mill is a strong guarantee of the powder fineness. Fineness test is an experimental work to specify powder fineness property characteristics through instruments and methods. Different applications requires variously to the characteristics of powder. And among all the indicators that reflect the characteristics of the powder, the fineness distribution draws the most attention.
According to statistics, there are hundreds of types of powder fineness tests. Sedimentation method, laser method, screening method, the image method and resistance method are the five commonly used methods. In addition, there are several commonly used test methods in specific industries and areas. The accuracy of the fineness test is higher and higher, which mainly due to the efforts of equipment manufacturers.
The fineness of the powder produced by Hongxing ball mill can reach to D97 ≤ 5μm in one time. On matter you choose which ball mill, the processing fineness can be adjusted freely between 300-3000 mesh, and 97% materials can go through the sieve. The grinding chamber of ball mill is with innovative design inside which without bearings and screws, which avoids the problems of fragility of bearing and its seal, and destruction of the machine caused by loosening screws.

As we all know, sand is indispensable in construction, modern reinforced concrete buildings and flat road cannot be separated from the tremendous contribution the sand industry has made for the economic construction. Sand industry is an industry with long history. Till today, it has become one of the basic industries supporting national modernization. Along with the continuous technological progress, industrial production is increasingly dependent on the efficiency and convenience brought by machinery, particularly in sand production.
China’s economic development has been lagging behind. In the past, the traditional production of sand is very backward, the economic policy was more tightening, the infrastructure construction was in a stagnant stage, so the demand for sand was not very high demand. The natural sand resources are more abundant, but it was difficult to exploit them. With the pursuit of production efficiency in the modern society, people increasingly focus on the benefits of the mobile crusher in the production of sand. The traditional river sand is replaced by artificial sand which has more advantages. Artificial sand could achieve a unified specification in accordance with the demands, which avoids the waste in the use of traditional river sand. Therefore, the market demand for artificial sand is very broad.
In recent years, due to the more and more obvious adverse effects on the ecological balance of the destruction caused by of economic development, our state vigorously promotes environmental protection and the protection of ecological balance, and the supporting policies to sand industry greatly stimulate the development of the sand. The development of mining machinery will definitely drive the prosperity of the artificial sand. From the development trend of sand industry, in order to grasp the mechanism of sand in this vast market, Chinese mining crushing industry, should also start from improving their own level, make good use of the opportunity of our nation to support the machinery and equipment manufacturing, improve self-research and innovation capabilities. Only in this way, China could improve the competitiveness of the crusher product in the international arena.

2012 cement industry status quo cannot be fathomed. On the one hand, the declining demand leads to business losses; on the other hand, the national policy planning supports the extension of industrial chain and the implementation of the transformation and upgrading, which has stimulated competition between crusher enterprises. But the infrastructure construction will expand the market demand for aggregate and reverse the situation of intensified competition in crusher industry.

At present, to extend the cement industry chain and to promote enterprise upgrading have become a new profit growth point in the cement companies. Cement companies also entered the downstream industry chain such as gravel and concrete. So the demand for rotary kiln, mobile crusher, impact breaker which are related to cement production and concrete materials increases.

With the depth of energy saving and environmental protection and waste comprehensive utilization, the construction garbage crusher is increasingly needed in the processing of the materials of brick, sand tailings, slag, and calcium carbide slag crushing. And mobile crusher, dedicated slag crusher, tailings sand production line, waste crushing equipment will become a major research and development focus of crusher manufacturers. According to the prediction of relevant personnel, construction waste crushing equipment is expected to become the new darling of the crushing equipment in the next 3-5 years, and energy saving and environmental protection equipment draws more and more attention.

With the rapid development of world economy, the social demand and scale of production of various metals, non-metallic, chemical, mineral, as well as cement and building materials are widening. Crusher plays a very important role in its development and becomes the pillar equipment, and cone crusher as the key crushing equipment achieves good development.
The wave of the world economic crisis has passed and all the countries are moving to meet a beautiful spring. Mining industry is no exception. Various mining industry manufacturing enterprises have been belligerently ready to develop their own advantages and make their own company to succeed in more areas.
So in the beneficial stage for the development of crushing industry, we mining machinery manufacturers should do the following.
1. to innovative the equipment, to use efficient and energy saving equipment in order to raise labor productivity and reduce production costs.
2. to improve scientific prospecting work and increase prospecting efficiency and results. 3. to strive to improve the metal recovery, reduce mining dilution and loss rates and improve the comprehensive recycling. To enhance the technological content of products.
4. to unify with the mining technology service unit and to jointly do a good job in the mining technological innovation and new project development.
5. to spend certain amount of money train workers, work and improve their technical quality. Only when enterprises have a number of talents good at business techniques and specializing in modern management, and a large number of skilled workers, the enterprises could improve the management level and promote the progress of mining enterprises prospecting, mining, beneficiation and smelting technology.
