Maintenance Technology of Bearing of Sand Maker

The development of artificial sand suits several policies of the govt, and it’s several blessings, for instance, it’s ready to form up for the inadequate provide of the medium and coarse sand within the natural sand resources; it is unnaturally mix the sand grading; the Alimentateur vibrant prix composition of the sand is controlled artificially; numerous tailings and waste stone materials is wont to manufacture the bogus sand. The shortage of sand resources opens wide development space for the popularization and application of artificial sand.
When 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 kiln machine, the grinding mill also plays an important role, so that the correct operation of the grinding mill is also important.
Sand maker is suitable for crushing and reshaping soft, medium-hard and super-hard materials, and it is widely used in all kinds of kiln machine rocks, cement, refractory materials, iron, glasses, artificial sand and stone and all kinds of metallurgical residues, and it has higher production capacity in producing silicon carbide and bauxite and other high-hard and super-hard materials and abrasive-resisting materials. Sand maker is widely used in the pre-phase in the grinding process, and it will produce large quantities of powder rocks and reduce the grinding load whose cost is extremely high. Among the mechanical equipment, it turns to the impacting and grinding effects of the medium and the rocks themselves, makes the granularity of the rocks further small until they are ground to powders.

The size of the sand making equipment and the volume of the oil box in the sand making production line are all small, so that the quantity of the lubricant oil is small, and the temperature of the oil during the working process is relatively high, so that it requires that the lubricant oil has higher heat stability and resistance to oxidation. As for some ore beneficiation equipment, especially for some machines in the mine that is easy to have fire and explosion, it requires lubricant with high non-flame property and the flammable mineral oil can never be used. Because the environment of the mines is very bad, there are a lot of coal dust, rock dust and water; the lubricant will inevitably be polluted by these impurities, so that the lubricant oil has to have better antirust, corrosion resistant and anti-emulsification property.

Integrated Process of Industrial Ore Dressing

Ore mined first by the initial jaw crusher broken by the crusher to a reasonable degree of fineness by the elevator after, even into the mill to the mine machine, crushed ore from theball mill grinding. After cleaning and grading of the mineral mixture in through the magnetic separator, due to a variety of different minerals than the susceptibility through magnetic force and mechanical force to the magnetic material mixture to separate. In the minerals to be separated out, as it contains large amounts of water, subject to the initial concentration thickener, and then by drying machine drying, you can get dry minerals. Iron ore beneficiation process is the most commonly used as a dressing process, relatively coarse ore extraction, the process requires more rigorous and meticulous, iron ore beneficiation technology improved, more conducive to the development of China’s steel industry, producing quality products Enhance the process of steel in the international competitiveness and quality, in addition to technical studies, the device also requires constant innovation, optimization, and create new standards.
The 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.
The product process of raw ores is to sieve the raw ores to the ore fines of 0 to 15mm and ore lumps of over 15mm. the ore fines are sent to the strong magnetic cylindrical ore storage bin by the belt conveyor as the materials of the product of strong magnetic separation. The ore lumps are sent to the bunker in front of the furnace through two-times screening by the belt conveyor as the materials of the roaster.

The process of roast working of the shaft furnace is to send the ores to the shaft furnace to be roasted, which can separate the ores to the waste rocks and valuable ores. The waste rocks are sent to the hillock by the belt conveyor and the winching system, while the valuable ores are sent to the weak magnetic cylindrical ores bin as the product of the materials of weak magnetic separation.
The working process of ore grinding and magnetic separation can be divided into the strong magnetic separation and weak magnetic separation. The primary of the ore grinding system is a closed circuit made by the ball mill and the separator, while the secondary is a closed circuit consisting by the ball mill and the water cyclone. The undersize sieves are embodied in both of the two ore grindings to control the particle sizes feeding the secondary from the first separation. The ore fines or the roasted ores are classified by the classifier after grinded by the ball mills.
To ensure the sorting effect, the pulp must have the certain residence time in each flotation cell and the too long time or too short will result in the loss of useful minerals, reducing the operation recovery. Therefore, the specifications of the flotation machine should be in line with the scale of dressing plant.

Detailed Account of Hydraulic Jaw Breaker

PE Jaw crusher has many features, such as crushing cavity is deep and there is no dead area, which improves feeding capacity and output, Energy-saving: single machine can save energy by 15% to 30%; the system can save energy by over 30% to 60%; Simple structure, convenient maintenance and use; stable performance, low operation cost; high reduction ratio and so on, it is widely used in mining, building materials, chemical industry, and metallurgy and so on.
During 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. When the oil pressure goes up, the plunger compression spring in the oil pressure adjusting gear will shift to the right side, and drive the plunger injection pump plunger to rotate in the anti-clockwise direction, shorten the effective path of the plunger in order to decrease the oil injection amount and restrict the system oil pressure to go higher. On the contrary, when the system oil pressure decreases, increase the oil injection amount in order to prevent the decrease of the system oil pressure so that the oil pressure of the hydraulic system is kept in the original set state.
When the crusher is working normally, the pressure functioned on the working cylinder by the toggle plate of the crusher is smaller than the thrust of the hydraulic cylinder, and the movement calve is in an upper extreme position, and the toggle plate will not move so that the crusher will crush materials normally.

If some uncrushable materials go into the crushing chamber of the jaw crusher, the crushing force will increase. At this time, the pressure functioned on the working cylinder by the toggle plate of the crusher will be higher than the thrust provided by the hydraulic cylinder, and the oil pressure in the high pressure oil chamber will increase in a second, the throttle valve will drive the movement valve to move, and the system will leak oil in order to limit the biggest thrust of the toggle plate in order to protect the machine.
With domestic infrastructure and the continued development of the national economy, China’s construction machinery market has become the focus of attention of the international equipment manufacturers, crushing machinery industry is no exception, and the entry of foreign capital, further exacerbating the degree of competition in the market, the domestic crushing machinery enterprises in order to tide of competition opportunities,rock crusher the primary problem is to improve the quality of the existing crushing equipment and technical content, to narrow advanced level abroad, to create their own brand to gain market initiative, broken by comparing the domestic and foreign the mechanical gap to mechanical status quo broken at home and abroad.

Velocity of Ball Mill Affects Its Efficiency

The ball mill is composed by simplified cylinder, the hollow shaft and the grinding head parts, simplified cylinder is a long cylindrical tube equipped with a grinding body, cylinder is made of steel, steel grinding body is usually with steel ball, which can be selected according to the granularity of abrasive materials, and material from the mill feed end of the hollow shaft into the cylinder body; when ball mill does simplified rotation, due to inertia and centrifugal force, it is posted near the cylinder liner on the cylinder body and be took away; due to its own gravity it is thrown down to a certain height.
The 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. So the impact of balls is small, the grinding effect is well. Stones are abrasive grinding, but the grinding effects are not very well; when rotary speed is increased, the balls will be promoted to a high level. Out of the cylinder, the ball goes up to a certain height along the whereabouts of the parabolic trajectory.
In the fall-down place, the impact of balls is strong. Stones are grinded by impacting, so the grinding effect is good. When the rotary speed exceeds a certain limit (high speed), without the whereabouts of the ball with the cylinder rotation, balls are in a centrifugal operation state. Now there is no impact on balls, grinding effects is very small role, so that the grinding stops.

Ore and water is continuously fed from feeding port, going through the hollow shaft into the cylinder. When the cylinder works according to the prescribed number of revolutions, the grinding media (steel balls, steel bars or gravel) and ore in the role of the centrifugal force and friction, go along the cylinder wall and rise to a certain height, and then are thrown out off the cylinder wall , then fall and slide down, so that the ore stripping the role of impact and friction constantly being grated, ground ore and water to form slurry, continuously added pressure to promote the formation of ore and water continuously from the exhaust through the hollow journal mine discharge side, the completion of the grinding operation.
In the permitting condition, concentrate the ball mill on the special ball mill chamber and reform the ball mill chamber to a special acoustic booth. The effect of it will be better than that of the sound insulation cover. However, we must pay attention to solve the problems such as the monitoring in the operating of ball mill, the internal heat dissipation and the maintenance of the ball mill.

Summarizing Development Trend of Flotation Machine

Flotation machine is equipment that directly finishes the flotation process, in flotation process, flotation-cell.html' flotation separator inflatable, mixes for the prepared slurry; particles selectively attached the bubble, so as to achieve separation of minerals from gangue. According to the mineralization of flotation industrial experience, bubble theory and study on the hydrodynamics of flotation, we make the following basic requirements for flotation machine:
Since the number of refractory ores in our country is quite large, and the contradiction between the ore dressing equipment and the separating technology is outstanding (the technology in the beneficiation reagent and the beneficiation craft is advanced in the domestic), with the flotation column being the most promising equipment, people should pay more attention to the follow-up study to surpass the advanced level of the world and do research the equipment adjusting to the characteristics of resources in our country. The main development directions of flotation machine include medium filling (create static environment and improve the efficiency of mineralization), microvesicle, combination of the disorganized flowing high efficient mineralization and the static split. The applying areas of this equipment is expanded day by day, e.g. to pre-eliminate the organics in the electrolyte to stabilize the electrolyte process, to float and eliminate the sediment of the ions as Cu, Pb, Hg, Fe, Zn, Cd in the waste water, to float the leaching ions in the polluting soil of the heavy metal ions, to void the pulp and to separate oil and water. Though we are just to start in these area, the future of the market is bright, which will bring opportunities to the research and application of the new type flotation equipment.

Though the structures and forms are of different degrees of development, the main aspects are as follows:
1. Bubble generator. Most of the bubble generators are improved by the susceptible to plugging built-in generators in the 1960s and 1970s, with some more advanced built-ins. The foaming manners are of great numbers, more advanced and more reasonable. The main types are the spiral bubble generator, venturi tube bubble generator, online mixer, efficient pneumatic hydraulic model inflatable device, CESL type ultrasonic generator in Canada, gas bubble dissolved air bubble generator and jet type bubble generator.
2. Filling Medium. Recently, the various types of filling mediums and medium beds have been appeared, which have solve the problems of the susceptibility to plugging if the filling mediums in the alkaline ores pulp and improve the stability of the ores pulp in the column and the segregating homogenization of the bubbles.
3. Height of the column. The height had been lowered by several meters. The height-diameter ratio has been decreased gradually. Even the height of the large flotation column is below 5m.
There are many reasons that can affect the flotation efficiency of iron ore concentrator, such as the granularity composition of the materials, the feeding size, the inflatable degree, the scrape of bubbles of fine ore, the content of drug, and the flotation flow.

Sand Maker Makes More High Quality Artificial Sand

In recent years, with the rapid development of the economic and social sciences, China’s housing construction, road building and infrastructure will usher in the peak period of development, which brings the perfect opportunity for the development of the mining machinery industry. Sand making equipment as the necessary equipment to obtain various construction materials, contributing a lot in the process of China’s infrastructure construction and has been the hero of the construction process. There are many manufacturers investment it in the domestic to start building sand making industry, and its sales lie in the competitive situation in the market.
Nowadays, sandstone industry gradually becomes the basic industry which supports the modernization program of our country. With the rapid development of the construction industry, regardless of the quality or number, the natural sand cannot meet the distensible demand of the sand market. However, as the indispensable gravel aggregate in construction industry, people began to turn their attention to the artificial sand industry.
The most commonly used equipment in artificial sand industry is sand maker. The grain size and the granular composition of the artificial sand can be adjusted, so it has a broad market prospect. In recent years, the evil consequence caused by the destruction of the ecological balance is more and more obvious. Our country vigorously promotes the environmental protection work and ecological balance protection work. The support policies on the sand and gravel industry also greatly stimulate the development of artificial sand industry. The boom of artificial sand will drive the development of crushing industry.

In the background of the promoting of infrastructure construction, Henan Hongxing mining machinery as the leader of mining industry produces the newest sand maker. It not only meets the requirements of the quality of building sand, but also compensates the technical defects of sand making industry. According to the different technology requirements and the different combination of equipment, we can meet customer's different process requirements.
The rapid development of the future economic puts forward new requirement on the artificial sand machine. The artificial sand machine will continuously upgrade with the customer's requirement. So, if the sand making industry want to catch the development opportunity in domestic, they should improve their own level and improve the independent research and innovation ability to enhance the international competitiveness of crusher product.
China’s construction industry has been in rapid development stage, which has the growing demand for gravel, but also the requirements for quality of the sand and gravel are increasingly high, such as railway construction has particularly high demand for sand and gravel. The demand of adverse natural sand rough appearance and shape for such a request is a constraint: the rough appearance and no round shape caused an adverse impact on liquidity in the concrete pouring; this poor liquidity will cause the voids in concrete, and directly have impact on the quality of the project. Therefore, the demand for artificial sand came into being, and it gets a great promotion and reuse.
