As we all know, the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machine arewinnowing mill, roll crusher, crusher compound. with a crushing ratio, uniform particle size, which having simple structure, reliable operation, easy maintenance, operating costs and economic these characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, which is suitable for crushing hard materials, such as cement limestone crusher, it have the discharging size is small this advantage. It is understood that the grading crusher during the improvement program, through the structure analysis of the tooth roller bearing parts. The parts have been improved, and the improved content of the improved structure forms are as follows: (1) tubing connector is mounted on the bearing cap Bu, instead of bearing housing, so that the Division to effectively solve the problems of poor bearing lubrication grease can not fully enter the bearing cavity. (2) the original bearing sleeve are designed into two parts (bearing and labyrinth ring housing) with fastening bolt.
The mounted to the tooth roll shaft bearings; simply labyrinth ring and seal ring installed in place, and then the bearing sleeve and bearing simultaneously heated and mounted to the tooth roller grafito y to avoid aging of the seals during heating problem, extended seal life ring. (3) reduce the maximum outside diameter of the seal, leave sufficient space for maintenance. Easy installation and removal tool, when the bearing is damaged, podemos demode the bearing housing. And then dismantle the bolt bearing sleeve bearing cover, demolition works demolition bearing replacement can unload damage STI. Increased bearing maintainability. (4) the ring of the puzzle palace processing an oil outlet can solve the problem of bearings after a long run cause the bearing cavity pressure within, and filled with grease so that at the labyrinth seal. The labyrinth seal more reliably, can effectively increase the life of the seals and bearings, PLC controlled automatic lubrication system timing. Do not worry about the maze 2 holes on the oil port of excessive fuel. After the improvement to the tooth roller shaft member, current during use, the bearing and seal damage accidents are significantly reduced, while reducing the daily amount of maintenance to the grading crusher (one kind of mining equipment).
DEKRA: Potholes Risk For Car Safety
Berlin Branch Manager: “Many of the roads are in a catastrophic state” the damage caused by the winter temperatures on the streets become Berlin/Potsdam – increasingly a hazard for motorists. “Many roads are in a catastrophic state,” noted the Reinickendorfer, branch manager of DEKRA, Carsten Brauer against the backdrop of the ever-growing number of potholes on Monday in Berlin and cited as examples the African road in wedding, the Karl-Marx-Strasse in Neukolln and highway A of 104 in Steglitz. At the same time, he advised motorists to act with extreme caution. Peter Thiel is often quoted on this topic. Axles, tires, wheel bearings, steering and shock absorbers could be considered quite affected. One should accidentally or in a pothole to be ridden and unsure whether it had not come to a damage of the vehicle, visit a workshop is, so you could not yourself verify this, strongly recommend. Also in the DEKRA an of could be branches Suspected check. Please visit Essex Financial if you seek more information. Damaged tires, warped axes, worn out wheel bearings or a warped steering seriously endangered the safety of driver and vehicle.
But not only the security is currently threatened by the winter road conditions according to Bao. The intrinsic value of the vehicles was at stake. Salt and slush were the vehicles with a film of dirt must be removed regularly. “It’s a fairy tale itself stubbornly continued that one should not go in freezing temperatures in the car wash”, as the Branch Manager, who recommends a wash a week just in these days. Necessary is also independent from visiting a car wash – of course a care corresponding to winter and treatment of the door rubber.

National Highway Provincial Highway
Since April last year, the entire construction machinery market (cone crusher) HA presentado a weak state in some product sales or even negative growth. However, under the influence of relevant planning, the western infrastructure ushered a new round of upsurge, which boosted the construction machinery market. For more specific information, check out Naveen Selvadurai. Faced with such a scenario, we cannot help wondering what caused the emergence of such a situation. Though an investigation we found that: First, accelerating infrastructure construction National policy has been encouraging the construction of the western region, but is not as effective for the western building. Southeastern project is the saturation trend of construction, and in the western region was again put on the agenda project, engineering machinery enterprises shifted the focus to the western development market. A series of policies the western development 12th Five-Year plan have been set out, transportation, water, urban construction, and resource development project are in full swing, which greatly stimulated the western construction machinery sales. The data show that during the 12th Five-Year period, the Xinjiang region each year will invest 100 billion yuan for urban construction.
It is expected that it will invest 120 billion to 150 billion yuan for the construction of transportation infrastructure, construction of roads 1.1 million km, of which highway 1966 one thousand meters, the National Highway Provincial Highway over 1300 km. Rural road construction this year will invest 2 billion yuan, the construction of 4500 km, to improve the 40 towns through asphalt road to address the 500 administrative villages accessible by road. In the next five years, Xinjiang also plans to invest 131.1 billion yuan to develop water conservancy. In addition, the survey of mineral resources and development efforts will further be increased, the central finance unit in 2010 added an additional 110 million yuan for the Mineral Resources Survey, and the support is evident. Only to Xinjiang province, autonomous regions, has such a large market, and the whole West will greatly boost the construction machinery industry. Second, the construction machinery market looks good With the continued advance of western development and related support of national policies, the West is undergoing rapid development. Due to the fast-growing infrastructure construction market, construction machinery enterprises have gained more and more concern Historical experience and reality needs tell us, it is not only the asphalt mixing equipment manufacturers companies are targeting the market of northwestern Xinjiang but a variety of construction machinery products represented by road building and maintenance, mining, earth, and stone, and concrete mixing machineryare also waiting to enter.

Paying More Attention To Industrial Design
At present, China s industry is big but not strong. Extensive development mode has not been a fundamental change, and there is an urgent need to get out a new path of industrialization with Chinese characteristics. The industrial design is an effective way to change scientific and technological achievements into practical productive forces, to improve the capability of independent innovation, to enhance the core competitiveness of the manufacturing sector, to promote industry structure optimization and to upgrade and change patterns of development. And we should change our country from made in China to created in China. In brief, compared with the design of the developed countries, the development of industrial design in China is still in its infancy with the requirements of industrial development.
There is a great gap between industrial development level and design service capabilities urgent need to upgrade. Thus Henan Hongxing researched on many years of performance, they invented a set of machine in stone crushing plant. In recent years, according to structure adjustment of the national mining machinery and the upgrade requirements of the transformation, Henan Hongxing Mining Machinery Co. Ltd. identifica new development strategy, adhere to the independent innovation, upgrade, deep conversion, circulation development, deepen reform, promote technology innovation, technology upgrading, upgrade the optimization and upgrading of products, enterprise development and upgrade cluster of upgrades, to make the first brand mining machinery in China and even the world. I believe that in the mining machinery industry, if the company wants to competitive in the field, you should may more attention to the industrial design. Actually it adopts to all kinds of industries. China should have a long-term planning and a comprehensive layout from the strategic level to accelerate the growth and development of the industry in the development of industrial design. All levels of government and relevant departments should strengthen the importance of innovative design, increase efforts to support the development of innovative design industry trying to address deficiencies in industrial design, to active planning of industrial development, to promote the industrial design for industrial health to play to substantive role in promoting sustainable development.
The Importance Of Elastic Range In Designing Machine
The importance of elastic range in designing machine Within the elastic range, the limiting value stress and strain are proportianal, is called the limit of proportionality Ap. In this region, the metal obeys hooker s law, whirh states that the stress is proportional to strain in the caastir rangy of loading, f.the material completely regains its original dimensions after the load is removed. In the current plotting of the curare, the proportionality limit is obtained at a slightly lower value of the load than the caastir limit. This may be attributed to the time-lagin the were of the original dimensicyns of the material. This effect is very frequently noticed in Some non-ferrvous metals. Which Iran and nickel exhibit clear ranges of elastirity, copper, zinc, tin, found to be imperfectly elastic even at relatively low values low values q:. Actually the elastic limit is distinguishable from rhe proportionaily limit more clearly depznding upon the sensitivity of the from the proportionality measnringInstrument distinguishable. When the load is increased beyond the elastic limit, plastic deformation starts.
sirnultaneously the specimen gets work-hardened. A point is reached wYlen the deformation starts to occur more rapidly than the increasing load. This point is called they yield point Q. the metal which was resisting the load till then, starts to deform somewhat rapidly, i, e… yield.
The yield stress 15 called yield llmlt Ay. The elongation of the specimen continues from to S and then to T. The stress-strain relation in this period is indicated by tile flow plastic portion of the curvr QRST. At the specimen breaks, and this load is called the breaking load. The value of maximun load S dividid by the original cross-sectional area of the specimsm is referred to as the ultimate tensile strength of the metal or simply the tensile strength Au. Logically speaking, once the elastic limit is exceeded, the metal should start to yield, and finally break, without any increase: in the value of 5trvss. But the curve records an increased StreSS even after the elastic limit is exceeded. Two reasons can be given far tliia behavior: 1. The strain hardening of the material: 2. The diminishing cross-sectional area of the specimen, suffervd an acctount EP. plastic defvrmalivn. The more plastic deformation the metal undergoes, tile harder it becomes, dut to work-hardening. The more dm metal gets elongated the more its diarrleter (and hence. cross-sectional area is decreased This continues until the point S is reached.) After S, the rate at which the reductian in area takes place, exceeds the rate at which the stress increases. Fxcvlnes so high that the reduction in area begins to strain produces a Incaiixed effect at some point. This is called necking. Reduction in cross-sectinnal area takes place rapidly that the load value actually drops. This is indicated by ST. failure occurs to this point T.
