On the market, there are many kinds of lubricating oils that can be used by ultrafine mill, and they are mostly similar in nature. But different kinds of lubricating oils are used in different environment, temperature, pressure speed and so on, that is to say, we can select the lubricating oils according to the differences of these factors. In general, when the crushers work with heavy load, the working parts are best to use more viscous lubricating oil. Because when the pressure is bigger, the oil will be extruded from the bearings, which will cause the rise in working temperature. When the rotating speed is small, we suggest to use more viscous oil, conversely, use less viscous oil. If the rotating speed and pressure are bigger, the less viscous oil can't be extruded, which will not cause the rise in working temperature. In winter, the temperature is low, the rock ultrafine mill that works in outdoor is preferred to use less viscous lubricating oil. Because the oil will be coagulated together and quickly harden along with the drop of temperature, which will bring a lot of resistance to the moving parts of ultrafine mills. Therefore, when choosing lubricating oil in winter, you'd better choose the lubricating oil whose temperature is lower 5 to 10 degrees centigrade than the surrounding temperature. If this kind of lubricating oil is lack in practical production, you can use all kinds of addictive’s or infiltrating diesel oil or solar oil so that you can tune into the required viscosity of lubricating oils. When selecting the types of lubricating oils or replacing oils, you should also take the wear degree of ultrafine mill parts into consideration. For example, the wearing parts generally use more viscous lubricating oils. When one kind of lubricating oil is replaced by another kind of lubricating oil, we can adopt according to its main quality indicator-viscosity. When using the lubricating oil in low temperature, condensation temperature of the oil should be considered. Correct and reasonable utilization of lubricating oil is very important to Chinese ultrafine mill and other crushing equipment, which is also one of the main reasons ensuring highly efficient production and proper maintenance of mining machines. The normal operation and efficient production are inseparable from the effect of lubricating oils. Especially for heavy mechanical equipment, the lubricating work of each part should be well done.

For a long time, mining machinery manufacturers are suffering the trouble of that the flotation is not complete, partly because it is difficult to identify some of the ore, and also the ore milling equipment technique is limited, which result in wherever the flotation result is not ideal. SBM mining machinery Co., Ltd, applies the turbocharged technology, the latest technology, breaking through the ore milling equipment's technologic difficulty. Floating mine is no longer a difficult problem, directly leading problem mentioned has been solved. Turbocharging technique is to use the waste gas generated from the operation of Internal Combustion Engine to drive Air compressor. Similar with Super Charger's function, both of them can increase the air flow into the internal combustion engine or boiler, to improve the machine efficiency. Common used in automobile engine, through the heat and flow of the discharging waste gas, turbocharger can improve the power output of internal combustion engine. First what is the turbocharger. Turbocharger's English name is Turbo, generally speaking, when we see Turbo or T in the car tail, namely that the car's engine is the Turbo engine. Believe that everyone in the road has seen many such vehicles, such as Audi A6 1. 8 T, Passat 1. 8 T, the Baolai 1. 8 T, and so on. Pressurization purpose: The main function of the turbocharged engine is to raise the air inflow, thus improving the engine's power and torque, making the ore milling equipment more powerful. When one engine is mounted by turbocharger, its highest power can increase 40% or higher than before. This also means that the same engine can produce more power after pressurization. For instance, the most common 1. 8 T turbo engine, after pressurization, power can reach on the level of 2. 4 L engine, however, fuel consumption is not higher than that of 1. 8, in any case, it improves fuel economy and reduces emissions. Flotation dressing is commonly used in flotation of mineral processing, the ore milling equipment is indispensable, and whose performance affects directly the flotation results. A better-performance ore milling equipment is a necessary hard condition for dressing flotation. If you intend to purchase ore milling equipment or consult on it, please come to the SBM Mining Machinery Company, or dial for consultation.

The rapid development of China's iron and steel industry makes the iron oredemand also grow, so a lot of lean ores whose grade lower than the average levelare mined and used, which leading to the increase of processing cost. Dry typeconstruction waste crusher technology can save energy and reduce the processingcost. construction waste crusher operation is normally taken in the mines, and itspurpose is to throw the tailings and improve the ore grade. Dry-construction waste crushertechnology has five advantages: ①Reduce transportation costs of theore; ②Improve the grade of crude, reduce wet-selectioncosts; ③Beneficiation medium is air without greater requirement of workingconditions; it is much better used in water-scarce areas; ④Tailings aredirectly discharged into the mine, and do not need to build a tailings pond. Inaddition, the tailings after simple treatment can be used for farmlandafforestation without environmental pollution; ⑤Most of the soil and mud arejettisoned with tailings in dry election, more favorable to subsequentsorting. In the beneficiation flow, dry-type construction waste crusher can be divided intopre-crushing pre-selection and pre-milling construction waste crusher. Pre-crushingpre-selection refers to the selection before secondary crushing and three-stagecrushing. It throws away non-magnetic minerals and barren rock that produced inthe last crushing process, greatly reducing consumption and pressure of thefollowing crushing. Pre-milling construction waste crusher refers to the selection betweenfine crushing process and grinding process. After crushing, magnetite materialand gangue are further separated, dry separation then can vastly improveconcentrate grade so that improve ore taste and reduce grinding quantity. Thedry type construction waste crusher has significantly obvious effect; it can greatly improveresource utilization, reduce processing cost, and has been popularized bycrushingmachine productionenterprises.

Our company has cooperation with Zambia cooper and cobalt production Mines Company in mining industry. During cooper and cobalt mining, crusher and industrial grinding mill from our company have made a huge role in ore crushing process. Our main products are crusher Used Mining Equipment For Saleand grinding mill such as jaw crusher, impact crusher, cone crusher, ball mill, vertical mill, Raymond mill, MTM medium speed trapezium grinding mill, MTW European trapezium grinding mill, MSB coarse powder grinding mill, SCM super thin grinding mill and so on. Also, we can supply some other optional equipment such as vibrating feeder, vibrating screen, belt conveyor and sand washing machine. And in recent years, our company has developed a new mining crushing machine named mobile crusher and it's welcomed in mining industry. Our bauxite crushing plant is widely used in bauxite beneficiation plant in Guinea, Vietnam,Jamaica,Brazil,Guyana,India,Iran, China, Australia,Greece, Suriname, Kazakhstan, Venezuela, Russia, United States etc. Bauxite crusher plant Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade or can be improved by a relatively simple and inexpensive process of removing clay. In many bauxites, clay is removed by some combination of washing, wet screening and cycloning, even by hand picking or sorting. Granite Crusher Granite go through vibrating feeder Stone Quarry Machines For Sale into jaw crusher for primary crushing, after primary crushing, the marble stones fall into impact crusher and cone crusher for fine crushing. The final materials can be screened out the suitable marbles using for buiding materials through screening machine. The unsuitable granites return to the crushing process for re-crushing. Granite Crusher Machine The main application of granite is Roadstone used in road bed, building blocks and raw materials for cement making. So granite crusher is used for crushing granite stones into suitable size.

The above-mentioned area theory, volume theory and fracture theory were proposed before the 1950s, surface grinding (grinding grain size 200-1000 mesh) and ultra-fine grinding (grinding grain size below) is 70 years later Appears, so the three power theory put forward can not consider the grinding mill and ultra-fine grinding of the power consumption. In front of the study of Hooke has been confirmed in the fine size of the grinding and ultrafine mill, that is, the use of area theory is not suited to calculate the error is too large. Therefore, must be in the three existing power theory and then in-depth look for fine grinding and ultra-fine grinding of the power consumption. The current mining project, the ore material crushing method is basically a mechanical crushing method dominated. Because the broken material has the following characteristics: (1) the tonnage is huge. Even a small concentrator, every day to break hundreds of tons of ore material, the election plant every day to break a few tons to tens of thousands of tons of ore. Which requires grinding equipment production capacity; (2) mineral hardness, wear and tear on the grinding equipment serious, which requires grinding equipment should be rugged and reliable; (3) high energy consumption, high material consumption, and the treatment of ore is cheap ore material, therefore. Broken cost is almost a decisive factor in the choice of crushing methods, and the fragmentation of low crushing methods is viable. The reason why the mechanical crushing method dominates because of its low cost. Although the mechanical crushing method has the disadvantages of high energy consumption, high material consumption and poor product characteristics, it can meet the requirements of the ore material for crushing. Present and future will remain the main method of broken ore.

Ball mill and a variety of other quarry crusher comparison has the following advantages: (1) has the advantages of simple structure; 2) operation is more reliable, occasionally fall when the metal is safe; (3) be good mixing effect of the ground material; 4. Get to the fineness of grinding, can grind all kinds of hardness of the material. The disadvantages of ball mill: electrical energy consumption; 2 dimensions, body is very heavy; third, large starting torque, work noise; ground water rate and the material with larger, especially turn the soil material when the material is easy to slay attached in ball mill, so the moisture content of the material rate is generally less than 3%. Cage quarry crusher is widely used in brick and tile factory. The reason is that the efficiency of the cage quarry crusher is high, and the fine powder particles (<=0.2mm) are high, which is beneficial to the brick forming. Maintenance is relatively large, but the failure rate is low, the water content of raw materials is not strict, generally within 12% will not affect the efficiency of fragmentation. Cage type crushing machine is suitable for crushing of soft brittle materials, such as industrial slag, dry Bo soil, shale, anthracite Bang stone, not suitable for crushing hard material. Also cage broken machine but also to on the edge of various raw materials doped with mixed edge broken, such as shale fly ash, industrial slag mixed with coal gangue, drilling soil mixed with fly ash, can achieve very good results. The roller crushing ratio general 3--15, material granularity can not great, the general should not exceed 25 m, available in the production line of medium crushing and fine crushing, if the raw material is medium hardness or soft cat material is the roller machine is suitable, such as coal gangue, shale, silt, and slay soil, slag and other raw materials are available to roller machine broken. To roll machine is the biggest drawback is the outer surface of the roller is easy to wear, the wear caused by the gap between the two rollers increase, can not guarantee that the aggregate size requirements, use often measured clearance and maintenance. In general, the molten night and grinding. At present, foreign advanced roller roller sheath of the special wear-resistant material production, the wear life is several times the ordinary materials, greatly improve the working efficiency and prolong the service life of the roller machine, our country hasn't been solved, in this direction. Wheel grinding machine is divided into wet and dry type two kinds, dry grinding wheel grinding machine requirements are broken raw material moisture content, generally around 6%, so rarely used. Wheel grinding machine has the advantages of simple structure, reliable operation, easy replacement of the worn parts, suitable for grinding various size of hard materials and ensure the grinding particle size. Wet wheel grinding machine in a brick factory is mainly used for the raw material grinding Lianzeng plastic, in order to facilitate the next step extrusion molding, especially high content fly ash brick, must use wheel grinding machine to ensure the molding material. The disadvantage of wheel mill is that it is of great weight and is not easy to transport and install.
