The Industrial Revolutionbegan in the late 18th and early 19th centuries and made a major shift in technological, socioeconomic, and cultural conditions. It originated in Britain and spread throughout the world. Revolution started with the mechanization of the textile industries, the development of iron-making techniques and the increased use of refined coal. On the other hand, the introduction of steam power and powered machinery underpinned the dramatic increases in production capacity. The effects of the industrial revolution spread throughout Western Europe and North America during the 19th century, eventually affecting most of the world (Hobsbawm, 2001). In 1850 the first Industrial Revolution merged into the Second Industrial Revolution, when technological and economic progress gained momentum with the development of steam-powered ships and railways. The period of time covered by the Industrial Revolution varies with different historians (Hobsbawm, 2001) .

The causes of the Industrial Revolution were complex and remain a topic for debate, with some historians seeing the Revolution as an outgrowth of social and institutional changes brought by the end of feudalism in Britain after the English Civil War in the 17th century (Kreis, 2007) .There are many theories about the beginning and the causes of the Industrial Revolution. Some thought it began because of the overseas colonies or profits which British gain from its slaves in Caribbean and Africa; however, it is only 5% of the British national income during the years of the Industrial Revolution. In addition, the greater liberalization of trade from a large merchant base may have allowed Britain to produce and utilize emerging scientific and technological developments more effectively than countries with stronger monarchies, particularly China and Russia. On the other hand, Britain's extensive exporting cottage industries also ensured markets were already available for many early forms of manufactured goods. The conflict resulted in most British warfare being conducted overseas, reducing the devastating effects of territorial conquest that affected much of Europe. In addition to the presence of a large domestic market an important driver of the Industrial Revolution should also be considered, particularly explaining why it occurred in Britain (Kreis, 2007).

One of the other theories about the Industrial Revolution is that Britain was able to succeed in the Industrial Revolution due to the availability of key resources it possessed. On the other hand, the stable political situation in Britain from around 1688 and British society's greater receptiveness to change (if to compare with other European countries) can also be said to be factors favouring the Industrial Revolution.

Historians sometimes consider protestant work ethics as an extremely important factor, along with the nature of the national economies involved. This theory presumed that the British advance was due to the presence of an entrepreneurial class which believed in progress, technology and hard work (Kreis, 2007). The existence of this class is often linked to the Protestant work ethics and the particular status of dissenting Protestant sects, such as the Quakers, Baptists and Presbyterians that had flourished with the English Civil War in the 17th century.

It became important and necessary to spread out the knowledge of the innovations by several ways which already spread out by the workers who were specially trained. The technique could move from one employer to another or could be poached. In addition, another method was to make a study tour and gather information. Study tours were common at that time and travle diaries were done. Another means to spread innovations was the network of informal philosophical societies, like the Lunar Society of Birmingham (Hartwell, 1971). These methods of knowledge transfer leaded to periodical publications about manufacturing and technology began to appear in the last decade of the 18th century. Foreign periodicals, such as the Annales des Mines, published accounts of travels made by French engineers who observed British methods on study tours.

In the late eighteenth and early nineteenth century a series of technological advances led to the Industrial Revolution. Because of the Britain's position as the world's pre-eminent, the nation was gifted by some of the world's greatest reserves of coal, the main fuel of the new revolution. It was also fueled by a rejection of mercantilism in favour of the predominance of Adam Smith's laissez-faire capitalism.

In the British economy and society the Industrial Revolution saw a rapid transformation; in the past the factories should be near the rivers or the forests. A new age stared when the use of coal engines spread out that allowed them to be placed in large urban centers. This was the reason for the more efficient production of goods than the cottage industry of a previous era. These manufactured goods were sold around the world, and raw materials and luxury goods were imported to Britain. After the first Industrial Revolution the empire became less important and less regarded. The British defeat in the American War of Independence deprived it of one of its biggest colonies. The formal empire afforded no great economic benefit when trade would continue whether the overseas political entities were nominally sovereign or not. The American Revolution helped to demonstrate this by showing that Britain could still control trade with the colonies without having to pay for their defense and governance (Kreis, 2007).

When the Industrial Revolution took place, the revolution itself included many industry fields such as mining, metallurgy, chemicals, steam power, textile manufacture, factories, machine tools, gas lighting, transport in Britain, navigable rivers, coastal sail, canals, roads and railways.

The coal mining in Britain, particularly in South Wales started early. Before the steam engine, pits were often shallow bell pits following a seam of coal along the surface which were abandoned as the coal was extracted. The introduction of the steam engine greatly facilitated the removal of water and enabled shafts to be made deeper, enabling more coal to be extracted. These were developments that had begun before the Industrial Revolution (Hartwell, 1971).While the major change in the metal industries during the era of the Industrial Revolution was the replacement of organic fuels based on wood with fossil fuel based on coal. On the other side, the British iron manufacturers had used considerable amounts of imported iron to supplement native supplies. An improvement was made in the production of steel, which was an expensive commodity and used only where iron would not do, such as for the cutting edge of tools and for springs. The supply of cheaper iron and steel aided the development of boilers and steam engines, and eventually railways. Improvements in machine tools allowed better working of iron and steel and further boosted the industrial growth of Britain.

The stationary steam engine was an essential early element of the Industrial Revolution; however, for most of the period of the Industrial Revolution, the majority of industries still relied on wind and water power as well as horse and man-power for driving small machines. This era started in 1712 when Thomas Newcomen invented the first successful machine. It was the atmospheric engine, a low performance steam engine which was spread out after his death to France, Germany, Austria, Hungary and Sweden. It work was fundamentally unchanged until James Watt succeeded in making his Watt steam engine in 1769 which incorporated a series of improvements, especially the separate steam condenser chamber. This improved engine efficiency by about a factor of five saving 75% on coal costs (Hartwell, 1971).

Usage of the spinning wheel and hand loom restricted the production capacity of the industry, but incremental advances increased productivity to the extent that manufactured cotton goods became the dominant British export by the early decades of the 19th century. India was displaced as the premier supplier of cotton goods. In the middle of the 18th century the Roller Spinning machine and the flyer-and-bobbin were patented by Lewis Paul and John Wyatt of Birmingham for drawing wool to a more even thickness. In 1743 a factory was opened in Northampton; fifty spindles turned on five of Paul and Wyatt's machines proving more successful than their first mill and operated until 1764. Other inventors increased the efficiency of the individual steps of spinning so that the supply of yarn increased greatly, which fed a weaving industry that was advancing with improvements to shuttles and the loom or 'frame'.

The Industrial Revolution could not have developed without machine tools, for they enabled manufacturing machines to be made. Machines were built by various craftsmen and carpenters made wooden framings, and smiths and turners made metal parts. A good example of how machine tools changed manufacturing took place in Birmingham, England, in 1830. The invention of a new machine by William Joseph Gillott, William Mitchell and James Stephen Perry allowed mass manufacture of robust, cheap steel pen nibs. The small metal parts were readily made by this means, but for large machine parts, production was very laborious and costly. In the first decade of the 19th century the first large machine tool was the cylinder boring machine used for boring the large-diameter cylinders on early steam engines. Although the milling machine was invented at this time, it was not developed as a serious workshop tool until during the Second Industrial Revolution. The machine tools manufacturing had many changes and development till the first third of the century when James Fox of Derby had a healthy export trade in machine tools. The industrialization also led to the creation of the factory. While the factory system was largely responsible for the rise of the modern city, as workers migrated into the cities in search of employment in the factories.

Gas lighting was another major industry of the later Industrial Revolution. The first gas lighting utilities were established in London in 1812-1820. Gas lighting had in impact on social and industrial organization because it allowed factories and stores to remain open longer than with tallow candles or oil. The Industrial Revolution improved Britain's transport infrastructure with a turnpike road network, a canal, and waterway network, and a railway network (Hartwell, 1963). In addition, the major rivers of the United Kingdom were made more navigable during the Industrial Revolution. The Severn, in particular, was used for the movement of goods to the Midlands which had been imported into Bristol from abroad, and for the export of goods from centers of production in Shropshire such as iron goods from Coalbrookdale (Hartwell, 1963). The major international seaports such as London, Bristol, and Liverpool were the means by which raw materials such as cotton might be imported and finished goods exported. Canals began to be built in the late eighteenth century to link the major manufacturing centres in the Midlands and north with seaports and with London, at that time the largest manufacturing centre in the country. Before the Industrial Revolution, most of the original British road system was poorly maintained by thousands of local parishes, but from the 1720s turnpike trusts were set up to charge tolls and maintain some roads. Increasing number of main roads was turnpiked from the 1750s to the extent that almost every main road in England and Wales was the responsibility of some trust (Hartwell, 1963). Also chemicals were an important development during the Industrial Revolution especially when the Englishman John Roebuck invented the first of these was the production of sulfuric acid by the lead chamber process. Besides, the production of an alkalion a large scale became an important goal as well. The development of bleaching powder revolutionized the bleaching processes in the textile industry by dramatically reducing the time required from months to days. There is no doubt that the revolution made in the railways helped Britain's trade enormously, providing a quick and easy way of transport. However, no one can deny that the transition to industrialization was not wholly smooth. For example, a group of English workers known as Luddites formed to protest against industrialization and sometimes sabotage factories.

CNC lathe machines are generally run with coolant directed at the work piece as well as the cutting tools; this enables the work piece from getting too hot during the machining process and at the same time extends life of the cutting tools such as drills, reamers or carbide inserts. While there are certain cases where dry machining is practiced, the majority of CNC machining still takes place under a coolant flooded environment. It is therefore imperative that the CNC machine coolant lines be properly maintained to ensure consistent and uninterrupted coolant flow.

CNC machine coolant line maintenance begins with keeping the coolant line filters clean. Generally two filters are provided, the first one is a coarse filter that traps the coarse and larger chips and the second one being a fine filter that traps the smaller and finer chips. These filters need to be cleaned often, preferably once a day to enable smooth coolant flow. Additionally, to keep the lines and the coolant motor cleaner, it has been found that wrapping a fine mesh metallic wire cloth once around the coolant motor intake traps any fine debris that may have escaped the filters that come with the CNC lathe machine tool.

Secondly, coolant blocks that are usually at the end of the coolant line must be taken apart and cleaned at predetermined frequencies to remove any debris that may be clogging the fine holes that are built into them. When these holes get clogged, coolant flow will get affected. O-rings that are part of the coolant block assembly must be replaced in order to reduce or eliminate mixing of coolant and hydraulic fluids.

Thirdly, most CNC lathe machine shops use water miscible coolants and over time, these coolants tend to form a slimy material that starts to adhere to the coolant line hoses, thereby reducing the internal diameter of these hoses; this will also reduce coolant flow. One way of removing these slimy deposits is to remove the coolant block and unscrew the coolant hose from the coolant pump so the coolant hoses alone are isolated and blow off the slimy deposits using shop air at about eighty to ninety psi. Ensure that all safety precautions are taken when performing this step.

Thus by performing proper routine maintenance on cnc machine coolant lines, you can ensure reproducible coolant flow and coolant pressure that is important to effective metal cutting.

Hammer Mill

Techno Wings Hammer Mill (Screen type Machine) is more efficient. The grinding chamber consists of a serrated liner on top and screen at the bottom, At times due to higher oil content in spices, there are chances of the screen getting clogged with spices, thus chocking the grinding chamber. The material passes through the blower and gets discharged through the cyclone through a one way valve. The air generated in the grinding chamber passes out through the cyclone outlet on top. A Polyester dust bag can be fitted above the cyclone working like a dust collector, or we can offer you a totally enclosed dust collector (manually shaken type) or a pulse air type dust collector, the choice we however leave it to your kind decision. The attached illustrated catalog will also brief you about the type of machine manufactured by us.

Hammer Mill's Operation

The materials to be ground into the crushing chamber of hammer mill from feed hopper by gravity or through an auto feeder (optional) the beaters / blades inside the crushing chamber accelerate the material to a very high speed to the toothed liner placed at the upper half of the crushing chamber. Shearing pulverizes the material. The ground materials continuously sucked by a centrifugal blower through screens placed at the bottom periphery of the crushing chamber and conveyed through a pipe into the cyclone dust collector for bagging. Excess air filtered through a cotton balloon. Particle size varied using screens with different size hole.
