Sand washing machine are mainly used in building site, gravel plant, concrete dam building site of hydropower station, etc., and are used for washing away the stone powder and impurity in the sand made by the Sand Making Machine, to increase the sand quality, is an equipment to wash sand in coordination with the sand making machine.

To make sand making line run smoothly, sand washer must be chosen and used correctly. Henan Hongxing's sand washer and other sand making machines are in good quality and advanced technology.The sand washer has the features of reliable structure, convenient maintenance, big capacity, low power consumption, high cleaning level. The new sealling structure, totally closed oil bath type drive device and adjustable overflow weir plate promises that the machine works efficiently. The impeller drive device is seperated with water and the watered materiel avoiding that the bearing is damaged by deeping in water, sand, or contamination. The medium and fine sand are washed away less. The washed costruction sand's gradation and modulus of fineness can get the standard which is regulated in national ' construction sand' and ' construction scree and gravel'.

Working principle of Sand Washing Machine:

When the machine works, through the V belt and the speed reducer, the electrical machinery makes the gear reduction and then drives the impeller rotate slowly. The gravel flows into washing launder from the feeding launder, rolls with the impeller and grinds each other to rid impurities and destroy water vapour layers cladding on the gravel. At the same time, the water vapor level surrounding sand and crushed stone is distructed thus favors the dehydration. Meanwhile, adds water to create a strong water flow, promptly carries off the impurity and the small proportion foreign matters, and discharge from the overflow port tank washer, completes the cleaning action. The clean sand and crushed stone is carried off by the leaf blade, and is finally poured into the discharge chute from the revolving impeller, completes the cleaning action.

Mining machinery industry,a pillar industry in China’s economic construction and social development, plays an important role. With development of economy & technology, competitions in this field are getting more and more fierce. For the mining machinery industry trends in 2011, running the machines and keeping them going was a tough and expensive business, and in the end it proved more productive to break the mining operation into about mining equipment and mining new technology.

The overall level of mining machinery and the international advanced level there are still gaps. Mining machinery manufacturing power towards the journey, the opportunities and challenges. The soul of the manufacturing product design, product structure, function, quality, cost, delivery time and manufacturing ability, maintainability, scrap processing and post-human, Machine and environment relationship, in principle, are in the product design stage decision. Design capacity of product innovation has become a deciding competitive position in the global primary factor.Along with social progress and national economic development, human resources and increasing demand for energy, while China is a relatively resource-poor countries. As resource development, mining depth increased gradually extending to the ocean from land, resources, deteriorating mining conditions and safe exploitation of the situation is becoming increasingly serious; coal mining in China has reached the depth of 1000m, metal ore concentration 1380m, deposits increased mining depth , groundwater, gas, high stress, geological structure greatly increased difficulty of exploitation of resources.

There has been much discussion in the press and here, among other places, on the growing conflict between the growth of crops for food, and those for fuel. One now is starting to enter a time, when the energy cost of mining production may well fall under the same sort of scrutiny.Chinese Mining Machinery industry has started a praiseworthy effort to look at the energy costs of various methods for producing fossil fuels, and it in the past, tried to explain that there are ways to look at getting rock out of the ground that change the energy cost depending on the way in which mining company actually mines the rock – mining it in very small pieces, for example, costs more energy than pulling it out of the ground in big bits. But I think we have to go beyond that and look at the overall process, and consider that there might be alternate ways of mining that change the overall balance of the energy costs. Mining operations must consider many factors in choosing the equipment, and the mining methods that they use since they must plan on getting the most value from the operation, with a minimal cost.

To sum up, Due to the global rapid expansion requirements for iron ore, coal and ore, mining raised new development boom all over the world. The mining industry association predicted that, driving China and India needs expansion, global minerals price rise continuously and thus push the speed of the merger process of mining companies. Those mining machinery companies which hold excellent Research & Development Team and possess advanced technologies can survive forever in the competitive era.

Domestic Heavy Industry notices that, the only standard to measure products’ quality is to research and produce, meet clients’ demands according to markets’ demands. Insisting on improving product quality and meeting client visible and invisible demands have been Chinese primary goal in Heavy industry.

Competition in Chinese heavy industry shows new trends. Facing to this trend, all companies work hard to improve methods and technology, so as to raise comprehensive competences.

In 2011, domestic heavy machinery industry keeps running highly, and the import is supposed to be 15% increase above, while export 20% increase. But it will take a long period to recover its economic status i.e. 13.42 billion US Dollars before Financial Risk.

In June 2011, the month-on-month producer price indexes for the industrial sector maintained the same level over the previous month, or it was up by 7.1 percent over the same month last year. The month-on-month purchaser price indexes for the industrial sector was 0.2 percent up while the year-on-year growth was 10.5 percent. Not only changes of mining industry in Chinese market, but also there are tough changes in South Africa.

South Africa may strengthen mining laws because companies are compromising worker safety as they accelerate production amid rising commodity prices. South Africa, where Anglo American Plc (AAL), BHP Billiton Ltd. (BHP) and AngloGold Ashanti Ltd. (ANG) operate, is the world’s largest platinum producer and Africa’s biggest gold producer. Its mines are among the world’s deepest, and labor-intensive methods have made them some of the most dangerous. About 76 people died at South African mines from Jan. 1 to Aug. 15, compared with 79 a year earlier, government data show.

The ruling African National Congress is studying nationalization of mines following calls by its youth wing. Shabangu has resisted such a move, saying it may threaten investment in the industry. “I am surprised that while globally there is real concern about the state of the world economy, with all countries chasing investments to shore up their economies in a bid to drive growth and create sustainable jobs, we are grappling with a debate about nationalization,” she said. “We have seen some of the mining investments going to other mining jurisdictions.”

Of course, it happend many times in China. So we can consider that how important to choose mining machine with good quality, high satety and advanced technology. Henan Hongxing Mining Machinery Co. specializes in Jaw crusher, Impact crusher, Combination crusher, Sand maker, Flotation machine, High-strength raymond mill and other mining machine.
