Biological materials, also called biotechnology or biological technology. Applied biology and engineering application of the principle of biological materials, the function of the special living creatures, are directionally formed into a specific traits of biological new varieties of comprehensive science and technology. Biological engineering, in the 70s, developed on the basis of molecular biology, cell biology, including genetic engineering, cellular engineering, enzyme engineering, fermentation engineering and so on, contacted with each other, which are based on genetic engineering. Only through genetic engineering on biological transformation, it will be possible to press the human desire to produce more and better biological products. And genetic engineering achievements can be transformed into products only through the fermentation engineering .There are many cobras in a little hill, they all pace up and down around big stones, which causes the exploring mystery interests of local people. When the night fall, the big stones in this place shone in the light of blue, insects with phototoxic danced over the stones, the frogs jumped out to episite, then the cobras hided nearby were came out to prey on frogs. So, people called these stones as Snake eyes stones, later, the people understood that the snake eyes stones were fluorite ores.
The composition of fluorite is calcium fluoride, also known as fluor. Because it contains kinds of rare elements, it usually presents the color of purple red, viridity and wathet, the colorless transparent is rare and preciousness. Its crystalline forms are cube, octahedron and rhombic dodecahedron. If you put the fluorite ore under the ultraviolet rays, it will shining with a beautiful fluorescence.
Feeder grinding lines, include mining, crushing, grinding, flotation of the ore stones, during the process of which there must result in serious pollution on surrounding environment. although many mines in China have taken active measures for protecting the environment, it may be far enough, China’s mining environment needs to be improved further. Put on the daily production schedule of cleaner mine, the cleaner production  has catched more attention of our state.Mobile crushing station occupies a great proportion in the overseas exportation of our company, for a long time, the great number of the overseas customers’ orders in our company made local logistics index rise sharply, and also improved the local economy.

Cleaner production, in different stages of development or different countries, is called in different ways, for example “waste reduction” and “no waste process”, “pollution prevention”, etc. But their basic connotation is consistent, namely by taking precautions against pollution on the products and the production process, product and service .
Cleaner production essentially, is to take overall preventive environmental strategy in the production process and products, reducing or eliminating their potential harm on humans and the environment, while fully meeting human needs, to maximize the social and economic benefits. Specific measures include: the continuously improving design; using clean energy and raw materials; adopting advanced technology and equipment; ameliorating management; utilizing comprehensively; reducing pollution from the source, increasing resource utilization efficiency; reducing or avoiding the pollutants emission during the process of production, service and product using. Cleaner production is of great importance for implementing sustainable development.
The very first step should always be an analysis of the quarry, and especially the characteristics of the raw material. Of prime importance is the hardness of the material to be crushed. To describe this property the compressive strength, the Los Angeles Index or the Mohs Hardness should be determined and a point load test should be carried out.
The abrasiveness of the material has to be described by its Silica and free quartz content, as well as the abrasion index. Just as important is an expression of the stickiness. For this reason the moisture, the clay content and, in very difficult applications, the handling coefficient (shear test) has to be ascertained. Based on this data an overview of the selection criteria allows a pre-choice of the required crusher.
According to the above overview, one step crushing can be achieved by operating Jaw Crushers or Impact Crushers. These crusher types are fast running machines providing high kinetic energy, resulting in strong impact forces and high crushing ratios. The allowable maximum compressive strength of 320 Mpa is normally sufficient for most of the limestone applications.

At present, there exists many problems in the working process of high strength powder grinding mill, i.e, grinding speed is slow, raw materials are wasted too much and abrading the machine seriously and so on. As we all know, grinding speed determines work efficiency of high strength mill , especially for some difficult-broken materials, such as quartz. How to improve the grinding efficiency of high strength mill, this article will give you a weapon!
To improve work efficiency, firstly we have to see the whole combination of each machine, only if which works perfectly, efficiency certainly would be enhanced naturally. This is one breakthrough to improve the work efficiency of the mill. Besides, according to different raw materials, to choose different machine combination.
For the preparation methods of raw material are different, cement production can be dry (include semi-dry) process and wet (include semi-wet) process. Portland cement ① dry process. Drying all materials at the same time then grinding the material or first drying the grinded raw material powder then feed to the dry kiln and calcine into clinker. However, there is another way, add some water into the raw material powder to make the raw material ball, and then feed to kiln to calcined to clinker, this is called semi-wet process, also belongs to the dry process.
② Wet process, which is generally conducted by filling water into the raw material, grinding the wet raw material into raw slurry, and then feeding it into kiln to burn into clinker. Or dehydrate the wet processed prepared raw slurry into raw lump and then feed it into kiln to burn into clinker, which is semi-wet process, still remaining kind methods of wet process.
After 50 years of development, especially in the beginning of this century, China high pressure micro powder mill has been in “a golden period of development.” The development environment improved significantly, scale of production is growing rapidly, the product types appear initial changes. The stability and service of product improved significantly in Henan mining machinery industry. The production and sales has achieved a marvellous leap from the 25603 units in 2001 to 232409 units in 2010. In the last year of “The Eleventh Project” 2011, the sales of Raymond mill was 193531 units, which made record in domestic sales history. The Chinese market sales had outstripped a quarter of the world’s total sales.

Weakness of China construction machinery industry
In recent years, the industrial structure of China’s construction machinery industry has been rapid escalated, technology and R & D capability has been improved. China’s construction machinery industry products have made great progress. both in the high-end, large-scale or in intelligence The machinery industry analysts believe that although the Chinese construction machinery industry is showing a strong upward trend, the Chinese construction machinery enterprises in the product-level, technical level and technological innovation capability have big gaps with advanced foreign enterprises, many raw materials have to rely on import. In order to show strong competitive in international markets, it is necessary to cross this bridge of technological innovation for China Construction Machinery Industry.
There are three gaps for China’s construction machinery manufacturing industry in independent innovation:
First, problems of the technology source. Engineering machinery manufacturing enterprises generally have a social and public research platform, enterprise autonomy, originality and businesses through the introduction of technology and formed in the digestion and absorption of three sources of technology. Science and technology system reform causes the original part of the public nature of research institutions turn to the industrial sector which have no operating obligations and the ability to engage in the common technology. Moreover, from the point of view the entire innovation system of the construction machinery industry, the common structure is of absence;
Second, the role of innovation entities in the innovation process is obviously inadequate;
Third, at present, the domestic construction machinery R & D expenditure intensity is of small, experimental and testing platform investment is clearly not enough. There are not enough Experiments and data accumulated, there is no database support, and industry can not be innovative.
In short, to solve the problem of China’s construction machinery industry has been not only to explore how to improve the level of key parts, but to actively explore the problem to catch up with the world advanced level for a long time.

In 1980, Hongxing Mining Machinery imported the manufacturing technology of TJ and TH type vibrating screen from American RS Company, which are converted into the domestic models as YA Series circular vibrating screen and ZKX Series linear vibrating screen that are widely used in China. In 1996, Henan Hongxing Mining Machinery introduced the manufacturing technology of the LSK series round vibrating screen and the TISL series linear vibrating screen from Germany. These two screening machines are the improved products from KHD Company in 1980s, in which USL linear vibrating screen is 5 meters wide. This shows that the manufacturing level of the large and medium vibrating screen in China has taken a big step. In addition, Henan Hongxing Mining Machinery introduced the manufacturing technology of HLW vibrating screen from Kobe Steel in Japan, which was transformed to the domestic type as ZK series vibrating screen. The structure of this kind of vibrating screen is compact with light weight. The maximum size of the screening are is up to 27 ㎡, which is the largest liner vibrating screen in China.In the 1980s, small-case mines in China had developed rapidly; the demand for the crushers exceeded the supply. Due to funding limitations, the small mines didn’t want to choose high-price and difficult to maintenance jaw crusher. In order to meet these needs, many crusher manufacturers in China had introduced a wide range of small jaw crushers. The small jaw crusher had larger width which improved the output, and it was easy to match with ordinary jaw crusher. So that it was very popular in the small mines. The design standard and manufacturing level of Henan Hongxing Mining Machinery Company has reached the domestic advanced level. Professor Wang Hongxun and Mr. Ding Peihong designed the KX series of deep-cavity jaw crusher. Hundreds of devices have been in operation, praised by users.
At present, domestic common equipment for iron ore processing include jaw crusher, cone crusher and ultra-crushing impact crusher. The working principles of all kinds of crushers are different and the characteristics of the processing are different. The jaw crusher is mainly used for coarse crushing of raw ore. The iron ore can be made full use through cone crusher, after which the iron ore can be crushed through impact crusher to meet the required fineness of production.

According to different production we set, the production is usually 50-500 tons / h. It can also configure cone crusher or sand maker being based on the different materials.  And they are applied to many kinds of aggregates and artificial sand making operation, such as granite crushing, river gravel sand making, silica crushing, production of construction sand, basalt and limestone.  it is applicable to hydroelectric power, high-speed, building materials, urban construction industry,etc.
The mobile crushing station sets the process of feeding, breaking, conveying as one, it has the performance of excellent rock broken, aggregate production, broken work of open mining through the optimization of the working process, can form a powerful broken exercise automation line and finish various demand of processing work from different types of jointing, It has advanced design, good performance, high production efficiency, convenient maintenance, economic operation, stable and reliable work, compared with stone production line, it just like a small or medium-sized movable broken processing factory, whose working efficiency and operating costs are better than the same level or higher level stone production line.
At present, there are hundreds of PEW jaw crushers in various types of mines. In order to promote this type of product, the Beijing Mining Research Institute has established Beijing Novi Technology Co., LTD and jointed several famous crusher manufacturers to produce this series products. As early as 1930s, the PJ jaw crusher has reached 1500mm×2100 mm. This PJ jaw crusher has almost no significant changes for the late ten years. The PE compound pendulum jaw crusher is heading for the direction of larger-scale. In the 1960s, the maximum size PE crusher was 600mm×900mm. in the 1980s, PE – 750 mm x1060 mm, 900 mm x1200 mm, and 1200 mm×1500 mm series jaw crusher had been used in the large and medium-sized ore beneficiation plants and non-ferrous mine processing plants. “The quality index of the mobile crushing station and construction waste disposal equipment with the brand of our HONGXING machinery has caught up with the international advanced level.” The main director Wang said.

The status quo of construction machinery maintenance
Construction machinery is an important tool for construction projects; it is an important mean to achieve high-speed, high-quality, high efficiency, and low-cost production. Ensuring the construction site and construction machinery keep in good condition, increasing the efficiency and prolong life, is an important part of construction enterprises to enhance economic efficiency and enhance competitiveness. The main problems of engineering and mechanical maintenance at this stage:
1, Market imperfections
(1) The market system of construction machinery ( sand maker, belt conveyor )maintenance and the facilities are inadequate; each maintenance and management enterprise has always been in decentralized parallel tracks of the situation.
(2) Maintenance mode unreasonable. Different equipment and different components (lines) have different working environment and different reliability requirements, uniform maintenance mode will inevitably lead to the maintenance of excess or lack of maintenance.
(3) China’s construction machinery maintenance market is lack of unified management department.
(4) China’s construction machinery maintenance market is lack of a comprehensive maintenance and identification of standards, the maintenance quality of different maintenance company is uneven, which is difficult to control.
Maintenance system and management mode backward
(1) Do “regular mandatory maintenance, planned preventive repair” project is expected to overhaul the system is the major maintenance system.
(2) To develop the law of warranty period and operating content has big gap with the current status of construction machinery, easily resulting in the maintenance of excess or lack of maintenance.
(3) Low implementation level of maintenance and management of the rules and regulations causes weak maintenance and management.
3, lack of technical capacity
(1) The increasing in imported and domestic equipment and update technical requirements ask for equipment management, operation, maintenance personnel to improve the existing staff quality but which can not meet the development needs, resulting in equipment maintenance and management lag behind to meet the requirements and can not use construction machinery.
(2) Fault repair detection technology is backward. The judgment of the engineering and mechanical failure relies on the senses, which is of low accuracy.
(3) Poor maintenance, mechanical maintenance is still scattered and backward state in the manual operation.

Nobody in this planet has the perfect job. Including you. Here are the jobs that everyone, including you, should try at least once in their lives.
Waiter
It is one of the most basic of jobs and, in fact, quite a number of people (like Lady Gaga and Jen Aniston) have actually done this at some point of their lives. As you wait on tables, you learn qualities like patience, humility and subservience. The best part is that you earn more in tips that would make your salary look tiny.
Baby sitter
It might be justified if you wouldn’t want to associate yourself with what you consider a girl’s job. However, this job deserves at least one go because it might help you in your later life, apart from helping you make some extra bucks. Before marriage, men usually find kids extremely annoying and even repulsive to a great extent. When you opt for baby-sitting as a job, you learn how to deal with the very babies that made you cringe before. This could, in fact, be the first step you could take towards fatherhood and would be a great thing to do before you plan to start your own family. Even Anne Hathaway was a baby sitter before she hit it big time in Hollywood (if that’s any consolation).
Salesman
For the thrill of convincing someone to pay you money for something they don’t need. The more you succeed in it, the more your feeling of awesomeness. Learning the tricks of the selling trade, for example ,selling a n impact crusher, not only adds to your smartness but also to your inherent ability to manipulate others. Also, there certainly is some charm to a job that was Jerry Seinfield’s first.
Customer Service Representative
This particular job is more like stepping into somebody else’s shoes. To be more precise, all those customer care reps you have yelled your lungs out at, at some point of your life. You’ll realize that being a customer service executive is, indeed, a job much tougher and challenging than any other desk bound job that you might opt for. Hopefully, after this stint, you’ll stop holding the customer care rep. responsible for every fault of his employers.
Driver/ Chauffeur
You’re a man and there’s no thrill better than getting behind some nasty wheels. While driving a taxi might not exactly be as thrilling, getting yourself a job as a chauffeur of high profile businessman or a celebrity might just be the start of a fantastic experience. While you whisk them around the city, you also get to be a part of their everyday dealings, albeit indirectly. As you gain knowledge about the things they do, you might be able to incorporate them into your life and, perhaps, create your own success story. Even Brad Pitt drove his way right into Hollywood while chauffeuring a limousine.
