How does a Cone Crusher works- Mineral Processing
For more mineral processing videos visit my YouTube Channel: http://www.youtube.com/hsrivastav2011/videos Description: The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle Crushers. Cross-section of heavy-duty Symons cone crusher of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal beating below the gyratory head or cone. Power is transmitted from the source to the countershaft through a V-belt or direct drive. The countershaft has a bevel pinion pressed and keyed to it, and drives the gear on the eccentric assembly. The eccentric has a tapered, offset bore and provides the means whereby the head and main shaft follow an eccentric path during each cycle of rotation. Since a large gape is not required, the crushing shell or "bowl" flares outwards which allows for the swell of broken ore by providing an increasing cross-sectional area towards the discharge end. The cone crusher is therefore an excellent arrested crusher. The flare of the bowl allows a much greater head angle than in the gyratory crusher, while retaining the same angle between the crushing members. This gives the cone crusher Head and shell shapes of (a) gyratory,and (b)cone crushers a high capacity, since the capacity of gyratory crushers is roughly proportional to the diameter of the head.The head is protected by a replaceable mantle, which is held in place by a large locking nut threaded onto a collar bolted on the top of the head. The mantle is backed with plastic cement, or zinc, or more recently with an epoxy resin. Unlike a gyratory crusher, which is identified by the dimensions of the feed opening and the mantle diameter, a cone crusher is rated by the diameter of the cone lining. Cone crushers range in size from 559mm to 3.1 m and have capacities up to 1100 t h -1 with a discharge setting of 19 mm, although two 3.1 m Symons cone crushers, each with capacities of 3000t h -1, have been installed in a South African iron-ore plant (White, 1976). The throw of cone crushers can be up to five times that of primary crushers, which must withstand heavier working stresses. They are also operated at much higher speeds. The material passing through the crusher is subjected to a series of hammer-like blows rather than being gradually compressed as by the slowly moving head of the gyratory. The high-speed action allows particles to flow freely through the crusher, and the wide travel of the head creates a large opening between it and the bowl when in the fully open position. This permits the crushed fines to be rapidly discharged, making room for additional feed. The fast discharge and non-choking characteristics of the cone crusher allow a reduction ratio in the range 3-7:1, but this can be higher in some cases.

Storm Over Warlock by Andre Norton
The Throg task force struck the Terran survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. Eye-searing lances of energy lashed back and forth across the base with methodical accuracy. And a single cowering witness, flattened on a ledge in the heights above, knew that when the last of those yellow-red bolts fell, nothing human would be left alive down there. And so Shann Lantee, most menial of the Terrans attached to the camp on the planet Warlock, was left alone and weaponless in the strange, hostile world, the human prey of the aliens from space and the aliens on the ground alike.

Timeline of United States inventions (before 1890) | Wikipedia audio article
This is an audio version of the Wikipedia Article: Timeline of United States inventions (before 1890) Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ You can upload your own Wikipedia articles through: https://github.com/nodef/wikipedia-tts "The only true wisdom is in knowing you know nothing." - Socrates SUMMARY ======= A timeline of United States inventions (before 1890) encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Colonial Period to the Gilded Age, which have been achieved by inventors who are either native-born or naturalized citizens of the United States. Copyright protection secures a person's right to his or her first-to-invent claim of the original invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution, which gives the following enumerated power to the United States Congress: In 1641, the first patent in North America was issued to Samuel Winslow by the General Court of Massachusetts for a new method of making salt. On April 10, 1790, President George Washington signed the Patent Act of 1790 (1 Stat. 109) into law proclaiming that patents were to be authorized for "any useful art, manufacture, engine, machine, or device, or any improvement therein not before known or used". On July 31, 1790, Samuel Hopkins of Pittsford, Vermont became the first person in the United States to file and to be granted a patent for an improved method of "Making Pot and Pearl Ashes". The Patent Act of 1836 (Ch. 357, 5 Stat. 117) further clarified United States patent law to the extent of establishing a patent office where patent applications are filed, processed, and granted, contingent upon the language and scope of the claimant's invention, for a patent term of 14 years with an extension of up to an additional 7 years. However, the Uruguay Round Agreements Act of 1994 (URAA) changed the patent term in the United States to a total of 20 years, effective for patent applications filed on or after June 8, 1995, thus bringing United States patent law further into conformity with international patent law. The modern-day provisions of the law applied to inventions are laid out in Title 35 of the United States Code (Ch. 950, sec. 1, 66 Stat. 792). From 1836 to 2011, the United States Patent and Trademark Office (USPTO) has granted a total of 7,861,317 patents relating to several well-known inventions appearing throughout the timeline below.
