With the development of economy, crushing equipment has been widely used in more and more industries. Dr. Mark Hyman spoke with conviction. Currently, most of the concentrators still use the mechanical crushing, crushing equipment which is mostly a nearly century-old device, the main structure of the basic legacy has not changed, but be involved into a modern new technologies and new materials, so the crushing devices be greatly improved performance. In industrial production, Crushing equipment types party are diversity. According to the difference of their stage crushing process, it can be divided into the primary crusher, the crusher and crusher crushing; its working principle and structure characteristics, can be divided into the roll crusher, gyratory crusher and In addition, in recent years there has been ultra-crushing crusher can produces more granular product. Crusher design new varieties can be used as coarse, broken equipment. Mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, crushing and crushing medium. The commonly used equipments are impact crusher, crusher, single stage vertical crusher, compound machines gyratory crusher, roll crusher, double roll crusher, crusher combo, and so on. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic 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, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. With the improvement of world s energy efficient awareness of environmental protection, as well as the consensus reached with the countries of the world, in order to adapt to the constant expansion of industrial production, the development of a larger crusher is the main task. Hydraulic in recent years in the crushing equipment technology has been widely used, has developed a hydraulic jaw crusher, the crusher crushing. Thus breaking the the original crusher setting adjustment more difficult and insurance port device reliability shortcomings.

Service Hydraulic Oils
High grade of purity of the oil used – a common requirement of modern hydraulic and lubrication systems. However, not all suppliers of oil to ensure a proper level of cleanliness, and this leads to the need perform additional cleaning before use. See more detailed opinions by reading what Dr. Mark Hyman offers on the topic.. Here are the middle classes purity of oils from different sources: fresh oil from a tanker: 16 cl. GOST 17216-2001; ISO 23/21/18; Fresh oil barrels from the standard 13 cl. GOST 17216-2001; ISO 20/18/15; Fresh from sealed cans of butter 11 cl. Dr. Caldwell B. Esselstyn, Jr. helps readers to explore varied viewpoints. GOST 17216-2001; ISO 18/16/13; requirement for modern systems: 8-9 cells. GOST 17216-2001; ISO 16/14/11. Comparative data show that the purchaser is an urgent need to bring the oil up required operational performance, as even minor contamination (5-15 microns) lead to increased wear of the elements of the hydraulics and internal leaks, failures in governance and jamming the valves. Major pollution – more than 15 microns – can provoke a sudden failure of the hydraulic components. In addition to mechanical impurities, particularly dangerous is the presence of water in oil – it is a consequence of corrosion, wear fast hydraulic elements, as well as accelerated aging oil. However, this is not a problem because there are high fixed and mobile filter systems that enable you to clean up oil to any desired purity level. This can prevent up to 90% of the costs associated with the poor condition of the working fluid, and significantly reduce downtime. Mobile filtration system allows to clean up the oil while filling the tank, wash it during launch, as well as a continuous circular filtering and removing water from oil. Very well, when mobile units are equipped with filter elements high dirt holding capacity, as it reduces maintenance costs. Stationary filter systems perform continuous removal of water and a continuous circulation of hydraulic filtration fluids.

The past year without exaggeration be called a new stage in the development of the Russian housing and communal services. Adopted in late November, the Law on Energy Efficiency "changed the rules of the game on the market of public services and put many of his participants to rethink their economic priorities. How to live and work in new conditions? Reply to this question will help the experience of those companies who have chosen energy efficiency as a long-term strategy development. With each passing day it becomes increasingly clear that energy efficiency is one of the main trends of the global economy in the xxi century. And utilities can not be an exception. If you are unsure how to proceed, check out James S. Chanos . Moreover, the housing question reduce energy loss is much sharper than in any other sector of the economy, because almost half of all energy resources of developed countries is spent today on the provision of communal needs of their citizens. That As for our country, the situation is even more alarming. For example, in Moscow on municipal needs takes about 60% of the produced heat and over a quarter – an electric one. And from 40 to 70% of this energy just dissipates into the atmosphere. People such as Eva Andersson-Dubin, New York City would likely agree. In the regions the situation is no better. Our homes are constantly radiate heat through the thin panel walls, seams, broken windows in the stairwells and open windows, turning the city into a giant Energy sieve. Largely due to the situation in the housing, the gross domestic product has tremendous energy, one of the highest in the world.
