...Essay Thesis: Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. In our world today we have many problems. Problems that we are facing are environmental, social, and economic issues. This is due to the fact that traveling to work has become a hassle and when your using your car it also causes environmental damage. When people travel in their cars they have to fill it up with gas, which we have seen, gas prices increasing tremendously. This causes social problems because people dont want to travel because its too expensive. The environmental problems we have are the fact that CO2 emissions are polluting over environment and causing harm to everyone. The result of this is global warming which is affecting our environment and society. Economic issues are the fact that importing and exporting oil is expensive. This is why we need to find an alternative. Thats why Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. Maglev trains use electromagnets, which make the train levitate. This causes the train to cause no friction and may be a travel solution of the future. This means that it doesnt cause any noise pollution, which is great for ecosystems living around the track and also benefits society because then they dont have to here the noise of the train, which most people find annoying. Personally I live right by the GO......

...Presentation On Magnetic Levitation Trains For [pic] ABSTRACT Imagine a train that doesn't touch its track and think of the potential for lower guide way maintenance costs as a result. Imagine a train that speeds along much faster than anything on the highway with a ride as smooth as silk. Imagine that train being capable of speeds higher than any other ground-based transportation system. Maglev can provide this speed and compete directly with airline travel. As stated by American Maglev, "Maglev means magnetically levitated and propelled vehicles. The advantage of maglev is that it can achieve very high speed and acceleration/deceleration performance because the vehicles essentially "fly" at very low altitudes - unlike trains or cars; there is no surface contact or "friction" to slow them down. More speed = more passengers." Only when we have real revenue-producing systems in operation will be able to prove whether this is true or not. In Maglevwhich is short for MAGNETIC LEVITATIONhigh speed vehicles are lifted by magnetic repulsion, and propelled along an elevated guide way by powerful magnets attached to the vehicle. The vehicles do not physically contact the guide way, do not need engines, and do not burn fuel. Instead, they are magnetically propelled by electric power fed to coils located on the guide way. Indeed this is the beginning of the......

...Many are inefficient compared to other possibilities. Maglev trains have great potential for our fast paced world we live in; they can provide cheap and efficient transportation if further developed. This paper will demonstrate how maglev trains work with electromagnets. We will provide information about the history of early electromagnets. We will also provide information on the locomotion process, which is done through the generation of an electromagnet field by the rotor around the stationary magnet causing the torque from the magnet to pull or push it [1]. The paper will describe how each part of the electromagnet works. There are projects that we will discuss that helped further the development of electromagnets. Well inform the reader of current working models around the world. As well as describing the train and how it functions and various examples of the types of systems. We will also give information about the ethics behind the train. New technologies in todays world must not only perform in the short term but also into the foreseeable future. Sustainability is one of the most important factors to be considered before adopting any type of new technology, and Maglev trains are no exception. Luckily for maglevs the way they work leads to high sustainability. This paper will talk about sustainably as well. Through this paper one will gather greater knowledge about electromagnets and maglev...

...The B&O Railroad By: Jaime Lewis For: Professor Knutson November 26, 2013 CON 101 Abstract The construction of the Baltimore and Ohio Railroad started in July of 1828. The city of Baltimore came up with the idea to build this railroad from Baltimore to Ohio because of the competition throughout the popular seaports in the United States. Baltimore was already a popular city, but adding a train that could carry people as well as goods would make more people travel to Baltimore, and other places along the trains route, bring goods into Baltimore, and help keep Baltimore alive. The B&O railroad was always expanding. The railroad is best known for being the first railroad in the United States that used a steam locomotive. B&O Railroad Why was there a need for the Baltimore and Ohio Railroad? The Baltimore and Ohio Railroad was built due to competition throughout the main seaports in the United States. Due to the fact that Baltimore is at the top of the Chesapeake Bay, it had many advantages over other ports. Another way for goods to be transported from Baltimore all they way to Ohio was a great idea for Baltimore, therefore causing the plan for the B&O Railroad. During this time Baltimore was flooding with business. They constantly had ships coming into the harbor as well as trucks riding the highways. Baltimore was (and still is) such a popular and thriving city, so the railroad made sense to help keep business, and the city, alive. Baltimore had......

...Now a new transportation mode has occurred that can clearly compete with planes in both speed and safety. They are called MAGLEV trains. The full form and the basic working principle of MAGLEV are called magnetic levitation. Many believe this mode of transportation holds great promise and offers considerable advantages. These trains use far less energy than other types of transportation and do not pollute. They can run at an average speed of 250mph that can climb much higher. The beauty of MAGLEVS is that they travel on air. The consequent elimination of friction means much greater efficiency. Hence this gives an advantage over a regular train because there is no friction between wheels and the track. 2. WORKING PRINCIPLE The principle of magnetic levitation is that a vehicle can be suspended and propelled on a guidance track made with magnets. The vehicle on top of the track may be propelled with the help of a linear induction motor. Although the vehicle does not use steel rail they are still referred to as trains by definition they are along chain of vehicles which travel in the same direction. This is the definition of magnetic levitation (MAGLEV) train. As the frictional parts are minimum in this type of technology, the MAGLEV trains are known to have more speed, smoothness and less sound. The...

...in the development of a novel maglev vehicle concept. This prototype demonstrates many of the key advantages of the technology which uses permanent magnets for levitation and does not require any moving parts in a track bifurcation. Key design features and performance characteristics of the prototype are described: the control system for stable levitation, the linear synchronous motor for propulsion and the method of track switching. Alternative system configurations and other applications of the technology are also briefly discussed. 1 INTRODUCTION The repelling forces resulting from bringing like poles of two magnets together is a commonly experienced phenomenon. The use of this repelling force to levitate a vehicle was considered early in the exploration of maglev vehicle technologies (Pollgreen 1964, Olsen 1965), but was largely discarded due to poor performance of the magnetic materials available at the time. As SmCo materials became available, the approach was revisited but again set aside by most due to the materials high cost (Sinha 1987). In the 1980s and 90s NdFeB materials began to be developed as a low cost alternative and have steadily improved over time. Today, NdFeB magnetic materials offer a very economical option with more than adequate performance for use in maglev vehicles and their tracks. LaunchPoint Technologies, in collaboration with Applied Levitation and Fastransit Inc., has been developing a permanent magnet maglev vehicle concept which......

...PROJECT TITLE: TEAM MEMBERS : Datta TEAM MENTORS: BASIC AIM: Maglev Rahul Agrawal , Chirag Gagrani , Akhil Lohia , Sohum RP Suman , Sachin Agarwal Our project is to build a miniature working model of MAGLEV, or more specifically, we will make a car that can be instructed to move forward or backward on a short magnetic linear track by means of magnetic levitation. BACKGROUND: Magnetic levitation (maglev) is an innovative transportation technology. It is sometimes said to be the first fundamental innovation in the field of railroad technology since the invention of the railway. A high speed maglev train uses non-contact magnetic levitation, guidance and propulsion systems and has no wheels, axles and transmission. The replacement of mechanical components by wear-free electronics overcomes the technical restrictions of wheel-on-rail technology. Compared with traditional railways, maglev systems have features that could constitute an attractive transportation alternative: 1. High Speed 2. High Safety 3. Less Pollution 4. Low Energy Consumption PROJECT MOTIVATION: Magnetism has fascinated humans for centuries. So we were looking for a project based on the concept of magnetism. The idea for this project came after discussing with the coordinators and reading a Scientific American Article that described proposed maglev systems around the world and their potential for future travel. THEORY OF OPERATION: Maglev is defined as a family of technologies in which a......

...INTRODUCTION MAGNETIC LEVITATION TRASPORT, OR MAGLEV, IS A FORM OF TRANSPORTATION THAT SUSPENDS, GUIDES AND PROPELS VEHICLES VIA ELECTROMAGNETIC FORCE Air flights are and will remain beyond the reach of a major section of society, particularly in India. Moreover there are problems of wastage of time in air traffic delays and 2 growing safety concerns. Trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles. Besides, increasing pollution levels from automobiles, depleting fuel resources, critical dependence on the fuel import and due to a limited range of mobility of buses and cars the need for fast and reliable transportation is increasing throughout the world. High-speed rail has been the solution for many countries. Trains are fast, comfortable, and energy-efficient and magnetic levitation may be an even better solution.Development of magnetic levitated transport systems is under progress in developed countries and it is just a matter of time they make inroads to India as well. Therefore, it will be interesting to know about the science and technology behind mass ground transport system known as "magnetic flight". A LITTLE HISTORY In 1922 a German engineer named Hermann Kemper recorded his first ideas for an electromagnetic levitation train. He received a patent in 1934 and one year later demonstrated the first functioning...

...the 1970s that Japan and Germany showed interest in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be levitated above its track, or guideway, and propelled forward. Wheels, contact with the track, and moving parts are eliminated on the Maglev train, allowing the Maglev train to essentially move on air without friction. [pic] FIGURE[1] BASIC PRINCIPLE OF MAGLEV TRAIN Maglev can be used for both low and high speed transportation. The low speed Maglev is used for short distance travel. Birmingham, England used this low speed transportation between the years of 1984 and 1995. However, engineers are more interested in creating the high-speed Maglev vehicles. The higher speed vehicle can travel at speeds of nearly 343mph or 552 km/h. Magnetic Levitation mainly uses two different types of suspension, which are Electromagnetic Suspension and Electrodynamic Suspension. However, a third suspension system (Intuctrack) has recently been developed and is in the research and design phase. These suspension systems are what keep the train levitated off the track. PROPULSION SYSTEM ELECTRODYNAMIC PROPULSION IS THE BASIS OF THE MOVEMENT IN A MAGLEV SYSTEM. THE BASIC PRINCIPLE THAT ELECTROMAGNETIC...

...Intrpduction : Maglev systems are becoming a popular application around the globe. Maglev trains are popular in transportation stations in big countries like Germany, China, Japan and the United States of America due to the demand for high-speed transportation, as the general public transportation services become more congested with increase of population. Maglev trains are magnetically levitated trains that traverse in a very high speed, with only electricity being its main source of energy. The train propels forward without any friction from moving mechanical parts. It has many advantages with minor drawbacks. The basis of maglev trains mechanisms are magnetic levitation. This is achieved with the principal of repulsion and attraction between two magnetic poles. When two magnets have the same poles, it will repel with each other and when it has different poles, the result would be otherwise. There are currently three known maglev suspension systems. In this project report, we will be covering the basic principals of Electrodynamic Suspension Systems (EDS), Electromagnetic Suspension Systems (EMS) and Inductrack. The three suspension systems each have different characteristics and special features. While EDS and EMS both use only the interaction of magnets and superconductors, Inductrack uses coils on the track underneath the train body. All three suspension systems work under the same principal of magnetic levitation covered in this project report. The maglev......

...ABSTRACT Maglev has been a long standing dream of railway engineers for the past century. These engineers envisioned a train that could float above its tracks. They saw the enormous potential for a train like this. The research on magnetic train which called maglev train was started in the beginning of the 1990 century. This concept lay dormant for about60 years. Then Japanese started their research on maglev train in the beginning of 1970 & constructed their first test line in 1997. German also started their research on maglev train in early 1970. It took them ten years to complete their first test line. The train works on the principle of electromagnetic effect. In this there is no friction between the train and track. The electromagnet on the underside of train pulls it up to the ferromagnetic stator on the track & levitates the train. The magnet on the side keeps the train from side to side. A computer changes the amount of current to keep the train 1 cm from the track. This means there is no friction between track & train. As it is high speed train compare to other types of train also noise level due to this train very less & energy consume is less, it is very convenient & beneficial to use. CHAPTER 1:-INTRODUCTION 1.1 History:- Magneticlevitationis the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard, an American Rocket scientist, created......

...How works a Maglev train? A brief review of magnets will help explain how maglev (magneticlevitation) trains work. Every magnet has a north pole and a south pole. Similar poles of two magnets repel each other; opposite poles attract each other. These principles govern the levitation of maglev trains. Permanent magnetsare always magnetic.Electromagnetsare magnetic only when an electric current flows through them. The north and south poles of an electromagnet are related to the direction of the current. If the direction of the current is reversed, the poles are reversed. In maglevs that levitate by magneticrepulsion, the train lies over the guideway. Magnets on top of the guideway are oriented to repel similar poles of magnets in the bottom of the maglev. This pushes the train upward into a hovering position. This system is designed for maglevs that contain groups of extremely powerful superconducting electromagnets. These magnets use less electricity than conventional electromagnets, but they must be cooled to very low temperaturesfrom 269 degrees Celsius to 196 degrees Celsius. In maglevs that levitate by magnetic attraction, the bottom of the train wraps around the guideway. Levitation magnets on the underside of the guideway are positioned to attract the opposite poles of magnets on the wraparound section of the maglev. This raises the train off the track. The magnets in the guideway attract the wraparound section only strongly enough to raise the train a few......

...electricity, gravity etc. have been a constituent of earth science. The spinning of the earth and things like gravity force etc. is due to the earths magnetism property. Here we are introducing asimple DIY science project for studentsor hobbyist Maglev Train. Magnetic suspension, Maglev and Magnetic levitation are an approach by which a thing or any object is hanging without any support apart from the magnetic fields. This magnetic levitation approach is utilized for designing this simple maglev train. Actually the original maglev trains are very complex in design, but here we try to design a simple maglev train, which uses some permanent magnets, cardboard or wooden boards etc. Working Principle of Maglev Trains: The basic principle behind the magnetic levitation is to use the magnetism property to levitate any objects. Magnetism is a part of our elementary science, and the principle is that the like/same poles repel each other but the unlike/opposite poles attract each other. Actually our Maglev Train works on this principle of magnetism. The train floats on the guide rail due to this principle of magnetism that the magnetic forces.

crusher efficiency calculations

crusher efficiency calculations

The following example demonstrates a method of selecting the components of an aggregate plant. Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it does involve common crusher and screen units often used in aggregate plants.

Quarry rock of 12 in. maximum size is to be handled in a two-stage crusher plant at the rate of 70 tons per hour. The maximum size of output is to be 1 in., and separation of materials over 1 in. size and the minus 1 in. in the output is required. Select a jaw crusher like those included in this table.

The screens to be considered are a 1-in. screen with an estimated capacity of 2.7 tph/sq ft and a 1-in. screen with a capacity of 2.1 tph/sq ft. The solution will include the selection of adequate and economical crushers for the two stages and the sizes of screens between them and below the secondary stage.

For the primary crusher a jaw crusher will probably be most economical. A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizeswill have to be selected overloading the secondary crusher.

A grid chart or curve for the selected crusher shows that, for a 2-in. setting, 54% of the material will pass a 1-in. screen, or 46% will be retained (this is like Jaw Crusher capacity table abovewhere 48% passes a 1 in. screen). The 46% of 70 tph gives the 32 tph fed to the secondary crusher shown in Figure below as a roll crusher.

A twin-roll crusher is selected, like those given inthe Roll Crusher capacityTable above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in theRoll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough. The maximum size of feed coming from the discharge of the primary crusher with a setting of 2 is about 3 in. as may be found in this Table.

Considering a 30-in. diameter roll crusher the maximum size particle that can be nipped with the roll crusher set at 1 in. according to this Equation is F = 0.085(15) + 1.0 = 2.28 in. <3 in. feed. It will take larger than a 40-in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1 in., then a roll crusher from the Roll Crusher capacityTable above could be used. If the output of this crushing process should have less material of the +1-in. size, the larger crusher could be operated with a closed circuit. That is, the oversize in the output could be recirculated through the roll crusher without exceeding the rated capacity of the crusher. Then all material leaving that crusher with a 1-in. setting would be of a minus 1-in. size.

Another possible solution to this problem would be to use a gyratory crusher for the primary crushing stage. A gyratory like Telsmith model1110 could be set at 1 in. in an open circuit with a capacity for 260 tph. The maximum size of stone in the output is estimated to be approximately 2 1/8 in. Then all the output from the primary crusher could be nipped by a 40 in. diameter twin-roll crusher with a 1-in. setting according to the Roll Crusher capacityTable above. The specifications and manufactured limitations, rather than economy, generally govern the selection of crushers.

To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1-in. screen under the jaw crusher is the top deckno deck correction factor will be necessary. Therefore, the 1-in. screen will need to be at least 70/2.7 = 29.9 sq ft in area. It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft.

The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft. For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft. A 4-ft by 10-ft 1 in. screen should be satisfactory.
