With the energetic research and development of energy saving Raymond grinding equipment, this series of mining machines that are really used in the manufacturing and production have not been popularized or promoted. What on earth are the factors that lead to this situation? One of the main factors that is restricting the development of energy-saving Raymond grinding mill is the traditional grinding machines are not all out of service. Of course, if you want the energy saving one combined perfectly with the previously invested machines, the mining machinery manufacturing companies need to pay attention to the beneficial combination of the receiving and improvement of the existing Raymond grinders.

Because the investment and application of the not-energy-saving equipment lead to serious environmental pollution, then now we can conclude from it that we cannot only focus on industrial manufacturing but not care about what is going on in the outside world. According to the materials that collected by the research and development department in Hongxing Machinery, the engines that are configured in the existing old crushing engineering products are fit out on the product the moment that the new machines get down from the assembly line, the emission amount of carbon dioxide from the jaw type crusher is much higher than the existing industrial standard. The hydraulic system that is used in the old mechanical products has the problems of gas release and oil leakage which is also one of the factors that lead to environmental pollution and resources waste. Although these ancillary parts can be changed, if the customers dismantle and overhaul all the hydraulic system, the cost will be extremely high.

In fact if we carefully analyze this, we can find that if we completely change the spare parts that cause pollution in the working process, it cannot fundamentally save the cost. The relevant technicians of the research and development and engineering department of Hongxing Machinery analyzes that if we want to fundamentally solve this problem, we will have to solve the emission problem and begin from the driving system which has not yet got any attention from the crushing equipment manufacturing companies. The sales amount of engineering products is high, but compared with the whole engineering industry, it is actually not very important. For this reason, the research and development focus of jaw crusher manufacturing companies should be put on the engineering industry where the working environment is relatively stable. So, if we want to solve the energy saving and consumption reduction problem of engineering equipment, we can only succeed with the cooperation of two or more industries.

Experts from this industry stress that on the energy saving and consumption reduction problem, all companies should actively think wide and should not pursue blindly with the plan of compound driving force. After all, the engineering equipment is not a crushing toy, relying on power operation is just a expedient, and every way that is able to promote the energy saving and energy consumption is worth to be encouraged. Hongxing Machinery believe that if the mining machinery manufacturing companies want to gain more benefit margins, the energy-saving series Raymond mill is your perfect choice.

Japanese festivals revolve primarily around celebrations with family though there are certain occasions where men and women come together to celebrate. Some of the popular festivals celebrated in Japan are as follows:

• New Year"s Day: New year"s day is the most widely celebrated festival in Japan and is a complete family affair. People travel to visit their families during this time and all shops are shut to celebrate this time of the year. A lot of families also travel abroad at this time of the year as part of their yearly vacation, though the holiday period is only three days. Families also visit shrines to pray for health, wealth and overall well-being.

• Coming of Age Day - Seijin No Hi: This is another widely celebrated festival in Japan that falls on the second Monday of every January, where all young adults who have come of age, i.e. turned 20 that year, come together. Young women are dressed in extravagant kimonos that cost several thousand yen. They go with their families to Shinto shrines and pray for their well-being. This is a very popular festival and one of those rare occasions where you will see so many young girls dressed in their traditional outfits.

• Valentine"s Day: Just like in most parts of the world, Valentine"s Day is celebrated in Japan with great fervor. However, the Japanese Valentine"s day is a little twisted because here, only women are expected to profess their love for men by giving those gifts, mainly chocolate. There is another occasion where men do the same for women (White day - March 14). Valentine"s Day in Japan is symbolic of a deep commitment and not something that is celebrated for the heck of it. However, on this day women also gift the other men in their lives such as friends and male members of their families.

• Girl"s Day - Hina Matsuri: Popularly known as the doll festival, Hina Matsuri falls on March 3 each year. On this day parents of girls display dolls of an ancient Imperial couple in their houses, and in some cases, dolls of the couple"s courtesans and other servants along with peach blossoms and rice cakes are displayed at multiple levels to make one huge display. These dolls are displayed to take away bad luck from the girls of the house so that good fortune prevails. At the end of the day, i.e. midnight, the dolls should be put back into their boxes; else it is believed that the daughters of the house may never get married.

Iron ore fell to its lowest level of the year and copper plunged more than 6 per cent as Chinese investors led a wave of selling across industrial commodities markets amid concerns of a global economic slowdown.

The sharp falls came as the eurozone debt crisis entered a crucial week of negotiations. At the same time, however, investors are concerned by the possibility of a hard landing in China, which accounts for more than 40 per cent of demand for many industrial metals. Those fears have been exacerbated by the sharp drop in spot iron ore prices. Benchmark Australian iron ore " with a 62 per cent iron content " delivered to China, which had been relatively stable amid the commodities sell-off over the past few months, fell to $145 a tonne, down 20 per cent from an early September peak of $183. Duncan Hobbs, analyst at Macquarie, said the fall in the iron ore spot price was "reinforcing perceptions of a slowdown of the Chinese economy" and was affecting sentiment of other industrial metals in spite of bullish supply and demand fundamentals, especially in copper. China this week reported GDP growth of 9.1 per cent in the third quarter " the lowest in two years.

Analysts said large steel mills in China were reporting declining orders and that aggregate steel output should probably be reduced in the short term. Negative sentiment in China also weighed on industrial metals. Copper for delivery in three months at the London Metal Exchange, the bellwether of the base metals markets, fell as much as 6.5 per cent to a low of $6,710 a tonne. That was slightly more than a 14-month low of $6,635 touched this month, and the lowest close since July last year. Prices of copper and steel on the Shanghai Futures Exchange " seen as the clearest indicator of sentiment in China " have fallen even more sharply than global market prices in recent days. SHFE rebar " a form of steel bar used in construction " for delivery in three months has tumbled 20 per cent since September"s start, and on Thursday fell to within reach of a two-year low. Nicholas Snowdon, base metals analyst at Barclays Capital in New York, noted that Chinese companies and investors, who were ready buyers of metals only a few weeks ago, had turned sellers: "There has been growing pessimism over the possibility of a hard landing in China. It"s clear there have been some production cuts in the Chinese steel sector. It"s something a lot of hedge funds have pointed to as a sign of weakness in China."

Marius Kloppers, chief executive of BHP Billiton, the world"s largest mining company, told investors that the group had seen customers "behave conservatively in the light of global uncertainty". He added that companies were keeping a close watch on inventory levels, in light of "the potential need to tailor their plans if the global economic uncertainty continues". As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station. We also supply individual jaw crusher and Raymond mill as well as spare parts of them.

With the developing of economic, the social quantity demand and production size of various non-metal ore, cement, building material, etc. is expanding with the rapid increase of material crushing and grinding. Henan Hongxing Mining Machinery mainly supplies the crushing and grinding craft. The ore exploited from the ore mountain need the process of crushing, which can make the big sized material into some dimensional small granule. And this crushing process needs the jaw, cone and impact type crusher and other mining equipment. The crushed small granule is delivering via belt conveying machine into grinding mill to achieve the grinding with the mesh from 30 to 400. If it is specially required, the fineness granule can reach 2000-3250 mesh, which increases the manufacturing capacity and ore selecting efficiency rapidly.

Portable type series mobile crushing plant is developed according to novel series stone crushing equipment’s design idea, which expands the concept field of coarse crushing and fine crushing. This series crusher really supply simpler, higher efficient lower cost machines for clients. Its design idea is based on the client’s requirements, which clears faults of the crushing place, surroundings and the complex basic configurations. It has the advantage of reasonable matching, unobstructed discharge all line, reliable working, convenient operation, high efficiency and saving energy. Especially the mobility is very good, so it can extend with the raw material places or the construction place, and it can also make multiple matching, get to different product requirements.

Komatsu developed its first mobile crushing plant in 1991 – 12 years ago. Since then, giving due consideration to the current environmental problems and market needs, the company has put on the market a good number of new mobile crushing plants which are capable of finely crushing debris from demolished concrete structures and processing the crushed debris into reusable aggregates. The newly-developed portable impact crusher is equipped with an entirely new impact-type crusher that can crush concrete debris into aggregates of desired size more efficiently than the conventional crusher. On the basis of the above findings and to offer new functions that can easily be used even by the users of construction equipment, we set the following aims of development for a new moveable crusher.

(1) The new mobile crusher shall be of such size that it can be transported within the United States without any of its parts disassembled.

(2) In order to enable it to carry an exceptionally large work load, a crusher having as large a capacity as possible shall be newly developed.

(3) The maintainability of the new machine shall be as good as that of ordinary construction equipment.

In short, the development concept was a new crusher that can be mobiled easily which is equipped with a crusher having a very large capacity and which can be transported without any of its parts is assembled. This has made it possible for the company to add a powerful new model to its series and offer optimum crushers according to specific customer needs.

This mill is a kind of widely used mining equipment. The whole grinding mill is of a standing structure, features small occupying space and strong integration capacity. Raymond grinder is main part of the whole grinding machine; it is collocated with jaw type crusher, elevator, hopper, electromagnetic vibrating feeding machine, main unit, classifying equipment, collector, cloth deduster and high-pressure blower. Different Raymond grinder mills have different rollers, so the finished size is also different. Raymond grinder is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 Mesh to 325 Mesh according to requirements. The product size is adjustable in the range of 80-325 (600 the largest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.

Maintenance of this equipment:

1. Staff who should be responsible for milling machine must have a certain level of technology. Before operating milling machines, the operator must carry out the necessary technical training so that they understand the principles of performance milling machine, and are familiar with the operating regulations.

2. In order to make mill powder machine normal work, should develop "the safe operation of equipment maintenance system", it can guarantee long-term security mill operation.

3. When Raymond mill powder machine has been used for a period of time, the overhaul should be carried out, while the Roller Mill Central blade repair, and other vulnerable parts replacement processing, roll grinding equipment in use around the nut on the bolt should be carefully examined to see whether there is a loosening phenomenon Lubricants whether additional foot.

4. When the mill powder machine grinding roll device use time is more than 500 hours, replace the grinding roll, Inner rolling must be cleaned, damaged parts of should be replaced timely.

How is it operated?

When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then ball mill revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.
