Although US originate this idea‚ most of later period development is done by USSR + Bulgaria. Japanese explore the technology for polishing purpose. Other countries in this field are: India‚ CIS‚ England‚ France‚ and Germany etc. Process details: • In MAP‚ w/p is kept between the two magnets & the air gap in-between the w/p & the magnet is filled with Magnetic Abrasive Particles (MAPs)

according to the magnetic source‚ the magnetic separator can be divided to permanent magnetic separator and electromagnetic separator. 2‚ according to the strength of magnetic field‚ it can be divided into: (1) Weak magnetic separator‚ the surface magnetic strength HO=72-136 KA/m‚ magnetic force HgradH= (2.5-5.0) 1011 A/m. (2) Middle magnetic separator‚ the surface magnetic strength HO=160-480 KA/m; (3) Strong magnetic separator‚ the surface magnetic strength HO=480-1600 KA/m‚ magnetic force HgradH=

Nuclear disasters From Wikipedia‚ the free encyclopedia The list of the worst disasters at nuclear power plants and other facilities all over the world is presented below: During the 2011 Fukushima nuclear emergency in Japan‚ three nuclear reactors were damaged by explosions. Following an earthquake‚ tsunami‚ and failure of cooling systems at Fukushima Daiichi Nuclear Power Plant in Japan on March 11‚ 2011‚ a nuclear emergency was declared. This was the first time a nuclear emergency had

Nuclear Weapons Non-Proliferation is a limitation of production such as the Nuclear Non-Proliferation Treaty. The big five: United States‚ Britain‚ France‚ China‚ and former Soviet Union agreed to dismantle arsenals and signatory nations would not possess nuclear weapons (Conn). Although North Korea has become the world’s ninth nuclear power‚ they withdrew from the treaty in January 2003. Since then‚ North Korea processed enough plutonium for five nuclear bombs (Norris). America should and does

What is Nuclear Proliferation? Nuclear Proliferation is the spread of nuclear weapons‚ fissile material‚ and weapons-applicable nuclear technology and information‚ to nations which are not recognized as “Nuclear Weapon States” by the Treaty on the Nonproliferation of Nuclear Weapons; also known as Nuclear Proliferation Treaty or NPT. The purpose of the treaty was to help avoid the spread of nuclear weapons to those countries that have not been recognized as nuclear weapons states. NPT has

Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant‚ the fission process is used to generate heat for producing steam‚ which is used by a turbine to generate electricity. Nuclear energy usually means the part of the energy of an atomic nucleus‚ which can be released by fusion or fission or radioactive decay. What are the Benefits of Nuclear Energy Nuclear energy is the world’s largest source of emission-free energy. Nuclear power plants

The Benefits of Nuclear Technology Concerns about the disastrous event in the past make people to look into nuclear technology in a very negative perspective. For example‚ the 1979 partial meltdown of a reactor at Three Mile Island and the Chernobyl disaster in 1986. On that note‚ the most recent international event regarding nuclear technology possession‚ where Iran falls under probation for using nuclear technology for non-peaceful purposes (Iran entitled to use peaceful nuclear technology: EU

“Nuclear Technology is the leading international publication reporting on new information in all areas of the practical application of nuclear science.” (American Nuclear Society) Today‚ nuclear technology is used for a variety of reasons that include weapons‚ medicine‚ food and agriculture‚ smoke detectors‚ and environmental protection. However‚ many people see nuclear technology as a destruction that could eventually kill us all. In addition‚ people believe that if scientists keep developing and
