The Lubrication Device of the Ball Mill

The lubrication device is very important of the ball mill. When the main bearing of the ball mill works, the stale lubrication device is very necessary. The large scale ball mill often uses the oil pump for forced circulation lubrication. The lubrication of the main bearing of the ball mill can use the dynamic pressure and static and dynamic pressure. The hydrodynamic lubrication can be divided into the oil pump and the oil ring with oil. The main bearing of the ball mill is composed of the bearing cap, oil scraper plate, platen, eyehole, thermometer, bearing, spherical watts and the oil level hole. Lubrication of these expensive, large open gear systems presents a unique challenge due to the harsh environmental considerations, as well as heavily loaded conditions. Grinding or pulverizing mills are exposed to cement dust, mineral dust, coal dust, temperature extremes and heavy loads. These severe conditions magnify the need for superior lubricating products. Each slide ring runs in a bearing with two self-aligning and hydrodynamically lubricated slide shoes. One of the slide shoes at the drive end holds the mill in axial direction. In the others, the slide rings can move freely in axial direction to allow for longitudinal thermal expansion and contraction of the mill body.
The lubricating oil enters the bearing from the inlet pipe and the oil is injected into the hollow shaft. Then the oil is sent to the bearing bush. The lubricating oil in the bearing housing flows back from the oil return pipe and forms the closed loop fuel supply system through the filtration device and cooling device. The lubricating effect is very good. The oil level hole is used to check the amount of the oil in the fuel tank. Since the rotating speed of the milling machine is too low, the oil film generated by the hydrodynamic lubrication is very thin, which can not reach the liquid friction lubrication but the semi-liquid friction lubrication. The spare oil ring is installed in the milling machine for better stability and safety. The large and small ball mill uses the oil circle with oil lubrication.

Cause and Solution for Temperature Rise of Ball Mill

The rising temperature of the sliding shoe of the ball mill may make the viscosity of the lubricating oil reduce and make the carrying capacity reduce. The rising temperature of the sliding shoe of the ball mill may even cause the dry friction. Seriously, the bush may be burned. The rising temperature of the sliding is mainly from large amount of heat generated between the inner grinding body of the milling machine and the sliding. Part of the heat is taken away by the materials and the gas. The other part of the heat sends out through the cylinder. The heat of the cylinder body transfers to the sliding ring so that the temperature of the sliding shoe increases. In addition, the temperature of the environment is also a very important factor affecting the temperature of the sliding shoe.
In the design process, we can take some technological measures to reduce the temperature of the sliding shoe of the ball mill.
First, install the sprinklers in the ball mill can reduce the temperature inside the mill.
Second, lay the insulation materials under the liner of the end of the ball mill. The temperature rising in the mill comes from the guide of the heat in the mill. The temperature of the cement at the end of the mill is the highest, as a result, we should lay a layer of insulation material with impact resistance and high strength to cut off the heat transfer to the milling machine and reduce the temperature rising of the sliding ring.
Third, increase the amount of lubricating oil for the lubrication system and increase the cooling area of the cooler. The lubrication of the bearing of the sliding shoe uses the high and low pressure oil supply. Generally, before the start of the milling machine and after the stop of the milling machine, high pressure system is used for oil supply. After the machine is in normal operation, low pressure system is used for the oil supply. The low pressure system piping can be designed to three ways.

Hongxing Impact Crusher Is Favored by Sand Plant

The iron ore resources are very rich in China, and China has the largest ore classification, such as the hematite, limonite, sand iron ore, pyrite, ilmenite, phosphorus, iron ore and other varieties. The mining mineral processing equipment for beneficiation can maximize the grade of the iron ore as China's iron and steel manufacturing raw materials. When the iron ores are in the crushing process, the crusher machine is firstly used to complete the crushing operation. The common equipments include the jaw crusher and impact crusher. The impact crusher produced by Henan Hongxing Mining Machinery is made of the casting steel shell and the steel plate. The structure is durable, which is more suitable for the installation of the plate hammer.
The impact crusher is a kind of crusher machine which uses the impact energy to crush the materials. The impact crusher has very wide use, which is one of the indispensable equipments in stone production line. In the crushing process of the impact crusher, the limestone is wrapped by the wet materials so that the dust reduces. The viscosity of the mixture of the gravel and the wet soil reduces and the mobility increases, which can reduce the blockage of the materials. The mixed crushing process of the impact crusher can reduce the stripping of the surface soil of the limestone. The use of the ore resources becomes full. The processing of the two materials can reduce the construction and running costs of a set of processing system. The cement mixed crushing process can ensure the requirements of the discharging particle size of the materials to prevent the clogging phenomenon of the whole crushing cavity to ensure the smooth running of the whole system.
As the professional crushing equipment for crushing the iron ores, the quality of the impact crusher directly impacts the quality of the impact crusher so that the shell of the impact crusher is durable. There is liner installed in the crushing cavity which can effectively protect the crushing cavity of the impact crusher. The liner is made of the most advanced and durable manganese steel.

Impact Crusher Brings Development for Cement Industry

Some analysts have pointed out that as the domestic economy has stabilized, the cement industry in the first half of 2013 is expected to usher the profitability of the industry. According to the statistics, the total investment plan of the cement industry nationwide project investment amounted to 294.3 billion yuan in first 10 months in 2012, which decreased of 3.8%. The cumulative investment in new projects amounted to 63.9 billion yuan, which decreased of 38%. The cement investment in fixed asset is 114 billion yuan in first 10 months, which decreases of 4%. From the different areas, the cumulative year-on-year growth rate is 17% in northwest region. The cumulative year-on-year growth rate is 24% in southwest region. With the acceleration of the Development and Reform Commission about investment projects, such as infrastructure and steel industry and the advance of urbanization and western development strategy, this series of favorable factors will open market space for development of the cement building materials industry in China. In addition, the cement industry is closely related to the crusher machine industry. Affected by expanding market demand, the crusher industry's sales market will be opened. In the cement production process, the limestone has become the most commonly used material for the enterprises. Most of the limestone should be crushed and grinded before it is used to make cement. In the general crushing process, large amount dust will be usually generated, which will cause by environmental pollution. Since the cement enterprises are faced with the pressure from the Ministry of Environmental Protection, the quality requirements on the cement production equipment are higher. In addition, the silicon content in the limestone raw material for the production of cement has strong attrition for the hammerhead of the crusher machine. If the content is abnormal, the crushing process will become more difficult. As a result, the cement plant should choose the crushing equipment with high-tech content, high throughput and fine environmental protection. The crushing equipment should not only greatly reduce the running cost of the cement production line, but also should provide a favorable protection for the efficient production for the cement enterprises.
To deal with the upcoming market demand and alleviate the environmental pressure of the cement enterprises, Henan Hongxing Mining Machinery has introduced a lot of mining machines with novel design, stable performance, easy operation, long service life, low energy consumption and low emission.

How to Correctly Select the Beneficiation Process

Before the ore beneficiation process, the beginning stage of the test work is the most difficult. The research on the composition characteristics of the ore materials can help experimenters faster and more safely choose the beneficiation method and process. At the start of the study in the laboratory stage, it is best to adopt the effective methods in industrial production. When the sorting indicators are not satisfying, it is worth the potential of new technology to develop applications.
The first step for processing the ore is the crushing process, grinding process and the related sieving and grading operations. For most of the ore, the purpose for crushing and grinding is to achieve the dissociation of the mineral particles monomer. If the ore needs to be finely ground, any conventional method or process can be used to crush the samples into the feeding size of the laboratory grinding machine. Conversely, if the mineral ore gathers sufficient amount of particles with coarse particle size, the gravity concentration is very necessary. The crushing and grinding processes should adapt to the sorting process. In addition, the over crushing phenomenon should be avoided.
If the useful mineral particles are too coarse and there is great density difference compared with the gangue, you should firstly consider the gravity concentration. The most commonly used gravity concentration equipment is the heavy media beneficiation machine, jigger and the shaker. Only some sand deposits may use the long chute centrifugal concentrator, the cross-flow belt chute and other fine gravity concentration equipments. The entire process is based on the gravity concentration. In addition, in order to reduce the influence of the particle size and choose different devices according to the different granularity, the grading operation is very necessary before the gravity concentration.
Flotation can be seen as a universal principle. Almost all industrial minerals can be recovered by flotation. The separation efficiency for the symbiotic mineral is also not comparable. For the ores which are difficult to depend on the gravity concentration, the flotation test should be arranged. The scope of application of magnetic separation is very easy to make a clear judgment according to the magnetism of the minerals and the magnetic tape granularity. For example, the wet weak magnetic field magnetic separation method is mainly used for the recovery of magnetite and the pyrrhotite.
