Conventional wisdom holds that if one has nothing to hide, one has nothing to fear. The increasing ubiquity of unsleeping electronic eyes demonstrates that we all have something to hide, whether or not we believe it. Much of our daily lives could, when scrutinized without context, appear sinister or eccentric. This lesson has been learned the hard way by a still-anonymous (at time of writing) citizen of a town of France’s Maine-et-Loire region. A camera car operated by Google Street View, photographing the burg in question, happened to catch our man urinating in his front garden. The image has subsequently gone viral.

At this point, the only proper response is juvenile tittering, followed by sympathy. Such misfortune could have befallen any of us. Everybody-come on, we’re all grownups here-has taken relief in a location without a roof. In France, it’s indeed a cornerstone of the culture: This is the nation that gave us the purpose-built outdoor convenience called the pissoire impact crusher and professional sand maker. The sensible course for Street View’s inadvertent victim, who wasn’t the first, would have been to sportingly absorb the ribbing of his friends and wait for the online mob to be distracted by the next theremin-playing cat. Instead, incredibly, he has retained counsel and is seeking to force Google to remove the image. No matter that his face is blurred and that no one who didn’t intimately know the town of 3,000 people could possibly recognize him. He also wants €10,000 ($13,115) by way of compensation, which seems a low price to put on dignity, even for that of a Frenchman.

This appears an elementary failure to heed the Streisand Effect-the law which holds that attempting to suppress online information will inevitably result in its widespread dissemination. (The principle is named for Barbra Streisand, whose efforts to remove pictures of her Malibu home from the Internet made it one of the most famous dwellings in California). Perhaps the plaintiff is playing a cannier game. Before Street View’s car drove past, he was just a middle-aged Frenchman; had he not made a fuss, which is what he would have remained. However, in a world limitlessly willing to confer gratifying and profitable celebrity upon unlikely candidates, he might yet parlay this apparently idiotic lawsuit into chat show appearances, a reality show, and a branded range of bathroom appliances. From village idiot to global village idiot. He may not have known it at the time, but he was aiming at the stars.

Vertical mill is a large ideal grinding machine, and is widely used in cement industry, electric power, metallurgy, chemicals, and non-metallic mineral industry. It can grind coal, marble, granite, kaolin, hard coke etc. So it is also called vertical coal mill or vertical cement grinder.

When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.

Compared with ball type mill, what"s advantages of vertical coal mill ?

1. Low Investment Cost
This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.

2. Low Operation Cost
A. High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%.
B. Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime is long.

3. High Drying Ability
As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with diffirent humidity.

4. Simple and reliable operation
A. It is equipped with automatic control systems, so remote control makes it easy to operate.
B. It is equipmented with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.

5. the stability of product quality
As the material stays in the mill for a short time, the Raymond mill is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.

6. Maintenance convenience
By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.

7. Environmental protection
It is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state Environmental Protection.

The first requirement for a successful mine operation is a market for the product, metallic or nonmetallic. The second requirement is to deliver a quality salable product to that market for payment in an amount exceeding the cost of the operation. There are a vast number of mineral products, literally from A to Z, and there are an infinite number of ways to get them out of the ground and delivered in a form acceptable at the marketplace.

One may start by looking at what a particular industry needs, such as silica for glass or cement manufacture. Low-iron silica is desperately needed for making glass, and at least one California cement company would dearly love to see a prospector walk in the front door with samples from his nearby silica claims.

Another example, also nonmetallic, is bentonite clay, the water impervious material commonly mandated to line the floors, walls, and caps of landfill disposal sites. This material, which swells when wet, is extensively used in oil drilling mud. It frequently occurs along earthquake faults and it was along the Garlock Fault in Kern County that Joe Mathewson, a Los Angeles area resident, searched for the commodity in the 1980s. He found a suitable deposit on land next to Red Rock Canyon State Park east of Mojave. The swelling-type calcium clay was tested by independent laboratories and was determined to meet the low permeability specifications for landfill use.

Mathewson purchased the land, which had been actively mined during its pre-WWII years as the source of Old Dutch Cleanser kitchen and bath scrubbing powder. Over 120,000 tons of white, high-quality had been mined underground. It occurs as a layer over the pumicite, in places very close to the surface. The exposed edge of the clay overlooks Last Chance Canyon for thousands of feet. The layered beds in this portion of the Ricardo Formation dip twenty degrees northeast and plunge beneath Highway 14 to the north.

Mathewson had the pumicite tested for a variety of uses, such as an abrasive, a filler product, a pesticide carrier, and as a Portland cement additive. Investigations performed at the Mineral Research Laboratory, with the assistance of the Materials Testing Laboratory at California State Polytechnic University at Pomona, showed an increase in concrete strength using pumicite, but at an unacceptable cost.

Applications for a conditional use and operating permit for surface mining were submitted to Kern County and State of California officials in 1988 and after several revisions were approved in 1989. The Kern County Department of Planning and Development Services issued a Conditional Use Permit containing 46 major conditions required before, during, and after operating on the property. For several years truckload shipments were sent to an eastern market, but interest was weak. Meanwhile, the owner, determined to avoid capital expenses for equipment, located a contractor who would perform the necessary stripping and reclamation operations as needed, and truck the raw product to a distant mill for fine grinding. Removed overburden had to be carefully spread to conform to the existing topography and ground surface characteristics. In order to meet landfill specifications another contractor was hired to dry, crush, and vibrating screen by way of hammer crusher the on-site using a portable plant.

On those seldom-seen days in this region when the sun comes out, the inside passage of Alaska displays rare vistas that have been obscured by fog for weeks. Rainfall reaches 200 inches in some years. Sunny days thus would prompt me to lock the doors to the Alaska Territorial Assay Office and to venture alone into the far wilderness in my boat at high speed in my life-long search for gold.

Earlier years had been spent preparing for the quest, studying and working at the assaying, mining, and metallurgy of the precious metal in well-known mines and colleges of the American West. Alaska"s frontier became the forge which shaped my skills and individuality. The challenge to produce something useful to society from untouched regions went hand in hand with a concern for the undefended vastness and the impact mining activity might have on its grandeur.

My boat trip led from Ketchikan to all the land I could quickly reach by water. The arc of blue sky above me, the green adorning the land around me, the silvery darkness of the sea split by the arrow of the boat"s white wake, lured me far from my home port. The forests I reached had no human footprints or memory of them. Deer and black bear roamed these woods. The gray wolf was present but seldom seen. Sounds were of wind whistling through tall treetops, of water rushing to reach the sea, of the loon"s cry from its watery home, and of waves lapping against rocky beaches.

My only companion on these journeys was Duke, a Mackenzie husky of unfettered eagerness. With the boat beached or anchored nearby, Duke and I examined the exposed geology and rock along the shoreline. Inland exploration was hampered by the thick carpet of muskeg covering everything, including rock outcrops. The muskeg was a dense tangle of roots, vines, plants, bushes, leaves, and evergreen needles.

The banner year, the year of my find, was one of gradual, step-by-step success. The first indication was a pathfinder to gold rather than the mineral itself. I found pieces and chunks of white quartz on one bank of a river flowing into the salt water. Little vugs crushed by sand maker in the whiteness had a story to tell of former occupants long oxidized out of existence, departed metallic compounds often found with gold.

A mile into the Sitka spruce rain forest from the river, through devil" s club thorny growth and fallen five-foot-thick rotting trees, I found pieces of native gold lying on the rock shelf beside a log-cluttered stream. The loose nuggets and flakes and jaw crusher had washed down from the hillside or from upstream. Pieces of accompanying white quartz identical to those along the river let me know a vein existed someplace between the two waterways.

This mill is a kind of widely used mining equipment. The whole grinding mill is of a standing structure, features small occupying space and strong integration capacity. Raymond grinder is main part of the whole grinding machine; it is collocated with jaw type crusher, elevator, hopper, electromagnetic vibrating feeding machine, main unit, classifying equipment, collector, cloth deduster and high-pressure blower. Different Raymond grinder mills have different rollers, so the finished size is also different. Raymond grinder is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 Mesh to 325 Mesh according to requirements. The product size is adjustable in the range of 80-325 (600 the largest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.

Maintenance of this equipment:

1. Staff who should be responsible for milling machine must have a certain level of technology. Before operating milling machines, the operator must carry out the necessary technical training so that they understand the principles of performance milling machine, and are familiar with the operating regulations.

2. In order to make mill powder machine normal work, should develop "the safe operation of equipment maintenance system", it can guarantee long-term security mill operation.

3. When Raymond mill powder machine has been used for a period of time, the overhaul should be carried out, while the Roller Mill Central blade repair, and other vulnerable parts replacement processing, roll grinding equipment in use around the nut on the bolt should be carefully examined to see whether there is a loosening phenomenon Lubricants whether additional foot.

4. When the mill powder machine grinding roll device use time is more than 500 hours, replace the grinding roll, Inner rolling must be cleaned, damaged parts of should be replaced timely.

How is it operated?

When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then ball mill revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.

As we everyone knows, in the using progress of screening machine, it"s necessary to maintain this equipment. Then what"s its maintenance, how will it have a long life? Here, engineers of Hongxing Machinery will give you some tips for its maintenance.

1. When disassemble the surface of precision parts, should be especially careful to protect these parts of surface to avoid damage.

2. Open the machine parts of surface which would be rust and intend to be stored outside of machine more than a few hours, must be well protected and coated with oil, or coated with rust inhibitor.

3. Disassemble the machine parts with bearing surface and machined surface, should lay a wooden plate on the ground to prevent a direct contact between precision work surfaces and ground.

4. Before equipping parts on screening machine should be cleaning and oiling in advance.

5. Percussion of hammer direct to parts is not allowed when loading and unloading process, there must be copper stick or other pad between hammer and parts. It should be special attention to the damage and cracks of casting parts because of percussion. Sometimes the cracks of these parts would exist after operation heating only.

6. When the bearing is damaged, it is best to replace two of bearing at the same time. If due to limited condition, can not replace both two of bearing, should disassemble all the bearing, clean them and then do the installation.

7. When install a new vibrating screen mesh, must make the connection between screen mesh and screen box angle steel or groove steel firmed, and tighten them.

Main characteristics of this equipment:

1. The side plate and the beam of ZSR hot ore vibrating screen are made of high quality and heat -resisting stainless steel and they are connected firmly by ring groove rivet. That"s all for the high temperature of those materials under screening.

2. Special equipment is designed to fix the screen plate in order to make it work normally under high temperature. It is characteristic by the firm structure, the stable performance, the low noise and the high efficiency

The above are the suggestions to the maintenance of vibrating screen for mining use.
