The rare mineral such as demand, gold dust, platiniferous sand, quartz, rutile, zircon, urdite and ilmeniteetc, rare are enriched in the sand seam of the coastal region, and called sea sand. Sea sand ranks second in shallow sea mineralresources;its value is next to oil and nature gas.

Sand has become a very important mineral for the expansion of society. Not only is it used for glass but more so for making concrete, filling roads, reclamations, building sites, and for renourishing beaches. Each has its own requirements in respect of the quality of the sand.

For drum separator, permanent magnet wet drum separator and electro magnetic drum separator are common.

Hongxing permanent magnet wet drum separators have been beneficiating iron ore and heavy media successfully for decades. In iron ore processing, the wet drum separator separates magnetic iron ore such as magnetite from waste rock - at P80’s commonly down to 28μm. The feed mechanism and separation zone are optimised according to maximum flow principles. By introducing powerful neodymium iron boron magnets, fields of up to 7,000 Gauss can be achieved, meaning Steinert can also offer so-called medium-intensity magnetic separators.

In the early fifties there was a technical revolution. Henan Hongxing built the preheater, a starting point of a new aera of reducing the heat consumption of the clinker pyro-processing system by nearly 50% at this time. Today HXJQ is one of the technical leaders worldwide in this field. The raw meal processed in the kiln first passes through the preheater absorbing the heat content of the kiln.

In mining industry, screw separation machine is widely used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Waste mud or water for ore sand can be separated from the ores. It’s also usually applied to ore washing, desliming and dehydration and so on.

As environmental problems have gradually taken seriously, energy saving, environmental protection has become the theme of development countries, China has started construction waste to provide opportunities for industrial development. In the urbanization process, urban development, construction waste has become a burden, the world is facing many cities surrounded by the city"s garbage situation.

The future development of machinery industry in our country in the direction what is it? Taking Chinese bearing market as an example.

China"s bearing industry to effectively respond to the tremendous impact of the international financial crisis, from the steady rise of the second half of 2009, out of the woods. The industry to seriously implement the "equipment manufacturing revitalization plan" to accelerate the transformation of economic growth, focus on product mix and market restructuring in 2012 to achieve a stable and rapid development.

All sales personnels know that there is a real experience: the customer, especially the terminal customer is the ultimate referee of the machinery market. The user is the most critical referee. In front of the user, all of the commercial magic, development strategy, marketing model and artificial barriers are negligible. Therefore, it is extremely dangerous to ignore the value of the user. The temporary equipment of gravel production is one machine majoring in producing the construction sand and stone, which can stand on the top of the mountain of the same field by depending on the innovation of technology. Creating the special machine with advanced technology can enhance the competiveness of the fiercer market.

As the specialist mining machinery manufacturing company, Henan Hongxing Mining Machinery has almost 30 years’ development and dedicates itself to mining crushing equipment, grinding equipment and ore selecting equipment. Many years, with the technology of perfection with more perfection and after-sales’ service of perfection, Henan Hongxing Mining Machinery wins a great high benefit year by year. As the high quality of mining machinery equipment manufacturing company, we will create benefit for customers with first-rate technology, equipment and service to cooperate and create the national famous brand.

Mining machinery with low energy consumption, superior quality and reasonable price like stone crusher and sand maker are desperately needed in the modern society. As traditional crushing equipment of jaw crusher, it has a widely use in roadway, railroad, mine metallurgy, construction, etc department for its simple structure, reliable performance, easy repairing, etc. Crushing machine has been widely used in various sectors for many decades, such as mine, metallurgy, building materials, highway, railway, water conservancy and chemical industry.
