A cone crusher is generally used as a secondary crusher in a crushing circuit.
Industry is the ailing sector of the Brazilian economy, with production falling 2.7 percent in 2012 in spite of government incentives, and in contrast with the strong expansion of retail trade and the lowest unemployment rate in history.
The enigma of a stagnant economy that nevertheless has symptoms of growth that is happening too fast for the country to handle, including a shortage of labour and rising inflation, appears to be explained in several recent publications.
Some of the causes mentioned by economists are a fall in the number of young people joining the labour market and accumulated excess inventory.
The slowing of manufacturing activity is the chief concern of the government of President Dilma Rousseff and economic operators, because it accentuates a trend that calls into question the future of the country. Deindustrialisation, recognised years ago by industrialists and a few economists, is now hard to ignore.
Improved forecasts for this year are raising expectations. But low levels of investment, reflected in the 11.8 percent fall in production of capital goods in 2012 and the surge in inflation, which may cause the Central Bank to take measures to curb demand, do not support the promise of a vigorous recovery.
Results at the close of 2012 were "a bucket of cold water," frustrating hopes of resuming the path of growth and indicating that "the crisis is deeper" in Brazilian industry, and not just a circumstantial effect attributable to the severe problems facing the global economy, said Julio de Almeida, a consultant at the Institute for Industrial Development Studies (IEDI).
Brazil "has not kept up with the development of global industry" in the last 20 years, as China, South Korea and India have done, he told IPS. As it has not developed the most dynamic sectors, like electronics and the pharmaceutical industry, it has not advanced enough in technological innovations, either, he added.
For the past 15 years, industry and certain "organised services" have also been suffering from an accumulation of costs, whether logistical, financial or energy-related, which have harmed their competitiveness, he said.
To cap it all, wages have increased in the last five years at a rate much higher than productivity. Only last year they rose by an average of 5.8 percent, while productivity fell by 0.8 percent, according to IEDI.
It is possible for less competitive countries to survive if the world economy is growing at a good rate, but problems appeared with the crisis that broke out in 2008 in the United States and then spread mainly to Europe, which "shrank the industrial market" worldwide and created intense competition in the domestic Brazilian market, de Almeida said.
In spite of it all, de Almeida believes that this year there may be some recovery, thanks to government measures to reduce electricity costs, cut taxes for some industrial sectors, lower interest rates and stabilise exchange rates, as well as its announcement of large forthcoming investments in transport infrastructure.
However, it will be necessary to boost productivity by investing heavily in technological innovations, especially because Brazil's industrial base is "aged," he said.
In fact, the mechanical engineering industry, especially the automotive industry, is increasingly predominant in the country.
With its long production chain, ranging from automobile parts to agricultural machinery, the automotive segment represented 21 percent of industrial production in 2011, according to the National Association of Automobile Manufacturers (ANFAVEA).
This proportion has doubled in the last 20 years, while the contribution of manufacturing as a whole to GDP has declined, falling to 14.6 percent in 2011. In other words, the importance of automobiles in the Brazilian economy is still rising.
As a result, the main government measure to reduce the recessionary effects of the international financial crisis was to cut taxes on vehicles, from December 2008, after three months of a sharp decline in sales. The strategy had been used before in other crises.
Oil and steel are also key elements in Brazilian efforts to reverse deindustrialisation.
Recovery is being sought in the shipbuilding industry, taking advantage of the oil discovered under a salt layer deep below the sea bed of the Atlantic ocean, close to the Brazilian coast.
In order to bolster national production, legislation was designed to demand variable and increasing proportions of Brazilian-made components, that may reach up to 70 percent of every ship, platform, depth sounder and other equipment constructed for oil extraction.
All these state interventions, such as tax or financial incentives for specific sectors and measures seen as protectionist, including customs barriers and requirements for a high national content for products like automobiles, as well as oil tankers, are rejected by many free market analysts, who have a keen following among operators and media specialised in economics.
Deindustrialisation is not necessarily a "sickness," since "industry is doing badly, but Brazil is doing very well," with high employment and high wages, said economist Edmar Bacha in interviews last year when he announced a book he edited, titled "O Futuro da Indústria no Brasil" (The Future of Industry in Brazil), published in February 2013.
According to the book, the manufacturing sector in Brazil lost competitiveness mainly due to the rise in wages, which drove up costs.
The average wage in Brazil grew 14.4 percent a year between 2006 and 2011, a global record seconded at a great distance by Australia, which had nine percent wage growth, according to co-authors Beny Parnes and Gabriel Hartung.
Bacha, who took part in previous governments that implemented more free market economic policies, maintained that competitiveness is not built by protectionism, but by more open trade, allowing integration into international production chains. Mexico is cited as an example.
Taking a broader range of expert views, the only point of agreement about the loss of industrial capacity is that it is caused by lack of competitiveness. But there are broad differences in interpretations of its origins and solutions.
Analysts in the commodities sector, for instance, question the primacy attributed to industry as the driver of progress and innovation. They argue that agriculture today adds a great deal of technology and knowledge, involving scientific research and mechanisation.
But the Brazilian government is led by so-called "developmentalists," for whom economic growth is paramount, and chief among them is President Rousseff herself.
It is ironic, then, that industrial decline continues while the country is administered by leaders who prioritise the sector and, to recover its competitiveness, have adopted measures accused of being overly interventionist by the partisans of free market solutions.
A cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks. It has the advantage of reliable construction, VSI sand maker high productivity, easy adjustment and lower operational costs. The spring release system of a cone crusher acts an overload protection that allows tramp to pass through the crushing chamber without damage to the crusher.
For the most part advances in crusher design have moved slowly. Jaw crushers have remained virtually unchanged for sixty years. More reliability and higher production have been added to basic cone crusher designs that have also remained largely unchanged. Increases in rotating speed, have provided the largest variation.
According to the basic research of the cone crusher of the domestic and foreign experts, the experts of Henan Hongxing Mining Machinery will do the researches from different angles in aspect of the working mechanism and working performance of the crushers. The engineers of Henan Hongxing Mining Machinery will do meticulous research in terms of the laminated crushing theory of materials, the calculation of the production capacity of the cone crusher, laminated cavity type model, cavity type design planning, and the particle size distribution of the crushing products, the crushing cavity type and other multi objective optimization designs.
The largest advance in cone crusher reliability has been seen in the use of hydraulics to protect crushers from being damaged when Inscrutable objects enter the crushing chamber. Foreign objects, such as steel, can cause extensive damage to a cone crusher, and additional costs in lost production. The advance of hydraulic relief systems has greatly reduced downtime and improved the life of these machines.
The shape of the crushing cavity, the production capacity of crusher, power, sand washing machine consumption, lining board life, and size and shape products plays an important role, so crushing cavity technology, also called the crusher of core technology. Stone crusher And the main parameters of crusher eccentricity and eccentric set of speed and the shape of the crushing cavity are closely related.
Mineral washing machine is widely used to rough and select manganese, in particular best for the manganese ore particles buried in the soil. Its handing capacity is greater and is the ideal equipment for the businesses that are required for great productivity of ore and stone cleanliness.
In the mineral processing plant, the mineral washing machine plays an important role in it. The mineral washing machine also has a standard level working principle. When the mineral washing machine is working, the electric motor runs slowly with the impellor after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some low-weight wastes from washing launder. Through the above process, the washing function is finished. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impellor to finish the washing task.
Mineral washing machine is applied for washing applications in mineral processing plant, concrete batching plant, and industries like building materials production, transportation, chemistry, water conservancy, etc. Our mineral washing machine is a highly efficient machine which is designed on the basis of the detailed washing needs in mining industry and comes with features like good washing effect, reasonable structure, large capacity, and less materials loss during washing process. The transmission part of mineral washing machine is isolated from water and specific material, which could greatly reduce the error rate of the machine.
Irock Crushers, a Valley View, Ohio-based manufacturer of mobile screening and crushing equipment, has introduced the TS-409 Open Style Feeder Track Screening Plant.

What are the ill-effects of filter sand on buildings?
Filter sand is the term used for the material taken from the bottom of the lake or man made trough like ponds. This is not sand but washed mud with high levels of silt, mud and other chemicals, which has corrosive effects. Silt and mud are enemies of concrete. It means that we need to add more cement to increase the strength of the concrete and the danger is that it will lead to cracks in structure reducing the compressive strength and life of the structures.Single Stage Hammer Crusher Manufacturers
What is the alternative?
Manufactured sand is the alternative for river sand. Manufactured sand can now be produced in a stone crushing plant by implementing Vertical Shaft Impactors (VSI) and washing plant like the Ortner.
