Ore Crusher Shines in Environmental Protection | Teaching and ...

Henan Hongxing?s Jaw Crusher , cone crusher and other crushing equipment has given a hand to environmantal protection.Throughout the economic situation at home and abroad, as low carbon, energy saving, environmental protection of China?s stone has broad prospects, but also more difficult task. Ore is one of precious non-renewable resources given by nature. After artificial processing, ore add brick to people?s homes. With the development of infrastructure, ore is used more and more widely. Therefore, we must implement the scientific concept of development put forward by the central authorities into stone processing industry, improve industry production and management of the scientific and technological level as soon as possible, to promote the harmonious development of the industry, utmost appreciation for mineral products, make the full use of the stone resources in ore processing process, energy-saving environmental protection.

It mainly displays in: (1) under the influence of the international financial crisis, the international economy is in a slow recovery and growth. As the world?s largest iron ore exporter, the development of mineral industry faces a bigger challenge. The mineral enterprises should recognize the situation, ?face danger fearlessly?, and turn the crisis into an opportunity to realize the healthy development of industries and enterprises. (2) Due to disorderly competition in domestic ore machinery industry, domestic stone machinery manufacturing enterprises are also facing a huge impact and pressure in the market, price, talent, quality and delivery time, and less able to compete with imported stone machine.(3) there is a big gap compared with foreign iron ore industry of developed countries.

Stone material industry in China still exists generally low product class, low production efficiency and process management, and site management can?t keep up with common problems. Compared with advanced countries, the gap is still large. Under the leadership of mining machinery industry association, we keep positive coordination of relevant industries encourage policy issued by NDRC, and give preferential tax policies in terms of equipment and technological transformation to encourage enterprises to be active in equipment technical reform, improve the skill level of the ore crushing process.

As the pacesetter of mining crushing machinery industry, Henan Hongxing heavy industry, mine equipment leader, will continue to enterprise, innovate, and realize the industry overall level of improvement and the modernization of the ore crushing machinery industry in China. Our production, jaw crusher, cone crusher, Raymond Mill and so on all marketing at home and abroad, has obtained the customer consistent high praise.

LOS ANGELES (AP) ? Dwayne Johnson is home after hernia surgery.

The 40-year-old "G.I. Joe: Retaliation" star tweeted a photo of himself in a hospital bed Tuesday. He's flexing his muscles while wearing a Superman shirt and a hospital bonnet.

Johnson wrote that the doctor repaired three hernia tears. Johnson's publicist, Alan Nierob, says the actor is now recovering at home.

Johnson's latest film, "Pain & Gain," opens Friday. He can also been seen in "Fast & Furious 6" next month.

9 Materials That Will Change the Future of Manufacturing [Slide Show]

Researchers are developing cutting-edge foams, coatings, metals and other substances to make our homes, vehicles and gadgets more energy efficient and environmentally friendly

The future of manufacturing depends on a number of technological breakthroughs in robotics, sensors and high-performance computing, to name a few. But nothing will impact how things are made, and what they are capable of, more than the materials manufacturers use to make those things. New materials change both the manufacturing process and the end result.

Scientific American?s May special report ?How to Make the Next Big Thing? presents several new materials under development to help inventors and engineers deliver next-generation technologies. These ingredients include superinsulating aerogels for spacesuits, flexible concrete cloth for construction projects and complex natural polymers that could replace toxic plastics.

Yet this lineup of advanced materials merely scratches the surface. Carmakers, for example, are developing porous polymers and new steel alloys that are stronger and lighter than steel, ostensibly making vehicles both safer and more fuel efficient. And environmentally savvy entrepreneurs are growing fungi-based packing materials to provide a biodegradable alternative to Styrofoam.

The following slide show presents these and several other substances that manufacturers could someday us to make many of the things we use.

View a slide show of these cutting-edge materials.

Iran's leader accused of manipulating public views

TEHRAN, Iran (AP) ? Iran's armed forces joint chief of staff is accusing President Mahmoud Ahmadinejad of trying to manipulate public opinion.

It is the latest exchange of harsh rhetoric between outgoing Ahmadinejad and his conservative opponents ahead of the June election.

The conservative Khabaronline news website on Tuesday quoted Gen. Hasan Firouzabadi as saying that recent remarks made by Ahmadinejad were "unacceptable."

On Monday, the Iranian president ? without naming names ? complained that some people in power had tied the "hands and feet of his administration," while expecting it to work properly. Then on Tuesday, Ahmadinejad promised to disclose more against his opponents in the future.

Under Iranian law, manipulating public opinion is punishable by up to two years in prison.

Doctor: Dead bomb suspect had wounds 'head to toe'

BOSTON (AP) ? A doctor involved in treating the Boston Marathon bombing suspect who died in a gunbattle with police says he had injuries head to toe and all limbs intact when he arrived at the hospital.

Dr. David Schoenfeld said 26-year-old Tamerlan Tsarnaev was unconscious and had so many penetrating wounds when he arrived at Beth Israel Deaconess Medical Center early Friday that it isn't clear which ones killed him, and a medical examiner will have to determine the cause of death.

The second bombing suspect, 19-year-old Dzhokhar Tsarnaev, was in serious condition at the same hospital after his capture Friday night. The FBI has not allowed hospital officials to say any more about his wounds or condition.

Schoenfeld lives in the Boston suburb of Watertown and heard explosions from the shootout between the two brothers and police early Friday. He called the hospital to alert staff they likely would be getting injured people, then rushed in to coordinate preparations.

"We had three or four trauma teams in different rooms set up and ready," unsure of whether they would be treating a bombing suspect, injured police or bystanders, Schoenfeld said.

The older Tsarnaev's clothes had been cut off by emergency responders at the scene, so if he had been wearing a vest with explosives, he wasn't by the time he arrived at the hospital, the doctor said.

"From head to toe, every region of his body had injuries," he said. "His legs and arms were intact ? he wasn't blown into a million pieces" ? but he lost a pulse and was in cardiac arrest, meaning his heart and circulation had stopped, so CPR, or cardio-pulmonary resuscitation, was started.

Schoenfeld did not address police's assertion that Tsarnaev was run over by a car driven by his brother as he fled the gunfire.

The doctor said he couldn't discuss specific treatments in the case except to say what is usually done in such circumstances, including putting a needle in the chest to relieve pressure that can damage blood vessels, and cutting open the chest and using rib-spreaders to let doctors drain blood in the sac around the heart that can put pressure on the heart and keep it from beating.

"Once you've done all of those things ... if they don't respond there's really nothing you can do. You've exhausted the playbook," he said.

After 15 minutes of unsuccessful treatment, doctors pronounced him dead.

"We did everything we could" to try to save his life, Schoenfeld said.

How did the medical team react to treating the bombing suspect?

"There was some discussion in the emergency room about who it was. That discussion ended pretty quickly," Schoenfeld said. "It really doesn't matter who the person is. We're going to treat them as best we can."
