Pulverized coal molding process can be divided into cold press molding and hot press molding, which is dominated by cold press molding. Coal press molding is also divided into binder forming and no binder forming, which is dominated by binder forming. According to national conditions of our country, pulverized coal molding more uses cold press molding which is adding binder, medium and low pressure and without drying.
At present, people do take the protection of the environment very seriously and the "environmental law" has been released by all nations government. At the same time, the environment protection regulations are getting more and more rigorous. But in many cold areas, due to the need to burn a large number of coal each year and the annual emissions of soot and sulfur dioxide are more, these places have become the hardest hit by air pollution. Many countries have begun to rectify the polluted coal boilers, dismantle heavily polluted large chimneys massively, promote the use of clean fuel and develop the central heating and the use of briquette. The burning of coal will be gradually canceled.
In that case then, the role of coal briquette machine is thus more important than ever before. All things equal, the finished coal briquettes of coal briquette machine will improve coal economization efficiency, the ratio up to 30% ~40%. They enjoy the features of long combustion time, less dust and coal ash and full burning and so on. The soot emissions can be reduced by more than 90%, the particulate emissions reduce 80%, sulfur dioxide emissions reduce more than 70%, nitrogen oxide emissions reduce 30% -50% or more and carcinogens emissions reduce 60% -90%.It is especially effective in saving energy and environmental protection and fully in line with industrial policy which is advocated by various countries in the world.
Coal Briquette Machine can be used to press pulverized coal, coking coal, aluminum, iron, iron powder, carbon powder, coal powder, slag, gypsum, tailings, sludge, kaolin, clay, activated carbon and various kinds of powder, waste and waste residue in refractory materials, power plant, metallurgy, chemical industry, energy, transportation, heat supply and other industries.
The pressed materials of this pulverized coal briquetting machine is of energy conservation, environmental protection and easy transportation. It improves utilization rate of waste materials and has good economic and social benefits.

production steel slag crushing plant. Steel slag crushing machine innovation the steel slag crushing machine is a new upgrade and skill development for the multicylinder hydraulic cone crusher it was launched in minutes in the sales in the market have been all the same and the users reputation has soared it is called quotthe crushing expert of the stone production
Successful briquetting is not restricted to hydraulic piston presses. The process parameters (necessary pressure and temperature) can also be realized with roller briquetting machines. Hot briquetting at 350 MPa and 800 C of Midrex residues without sponge iron pellets is an option for recycling them in the Midrex shaft furnace.
an additional briquetting plant could be dispensed with and the existing roller press could be used for hot briquetting. Two pro-cedures are considered for adding the residues to DRI pellets during hot briquetting. The rst procedure feeds hot reduced pellets and dry, cold residual materials into the roller gap of

Steel slag briquette machine is a machine used for pressing the powdery materials into pellets. All the waste and auxiliary materials in the metallurgy that need to be placed into the furnace need to be pelleted with ball press machine including fly ash, pool mud, sinter, steel slag, iron finemeal, iron powder, aluminum ash powder, silico .
GY high pressure briquetting machine is a kind of pelletizing machine which can feed various kinds of dry and wet powder through the preliminary pessure device compulsorily into the roll press area and make into high bulk density ball.It is mainly applied in the coal, mining,metallurgy,fire-resistant materials,construction materials and other light metal industries.Our briquetting machines have been widely applied in China and abroad.
Since the first large high-pressure briquetting machine GY 750-300 was finished trial-manufacture in1989 ,We have formed three series, more than twenty models after mant tears of research,tests and improvements.The structure ,performance ,quality and service life of products have reached a world-advanced level.
The pre-pressing spring in the device will force the materials into the inter-space between the double rollers, then the materials shall be pre-pressed and transited to the arch groove of the pair-rollers.
The roller pits with the same shape are distributed evenly on the rollersurface. The 2 pair-rollers shall rotate at constant speed reversely through engagement drive. The rollers will suck the materials at the entry into the groove and forcibly compress them.
With the continuous rotation of the pair-roller, the ball shall be taken off by the elastic force and gravity. The roller rotates to compress and form the materials periodically with the continuous operation of the motor to realize the batch production.
As we know, waste from production is a considerable cost factor for plants. Economic solutions are in demand for handling these materials derived from industries of coal, mining, metallurgy, fire-resistant materials, construction materials, and other light metal industries, etc.And ZHONGYUAN briquetting machines are the best answers.
ZHONGYUAN briquetting machine could be applied in the materials, such as Iron Fines,Aluminum Ash,Magnesium Powder,Quicklime,Bauxite,Laterite Ore,Dolomite,Fly Ash,Flourite Powder,Manganese,Nickel,Sodium-Cyanide,Magnesium Hydroxide,Activated Carbon, etc.
Zhongyuan Briquetting Presses can be designed for different briquette shapes and sizes on the application. A variety of briquette shapes, such as elliptic, round, elliptic, pillowed, squared, and bread shape or other singular shapes are all available.
The size-range varies between 0 and 2 mm, according to the available fraction selected by the producer to produce the briquettes. The choice between very fine fractions (below 200-300 m) can have important consequences on press operating parameters, particularly regarding the method used to feed the moulding rolls. The ideal size-range would combine some coarser crystals to finer particles (< 100 m) in order to optimize the mix compacity and form a strong briquette.
Its moisture is generally below 0.3 %. Salt is very often fed hot to the briquetting press (40-60C) and this helps briquetting allowing a better combination of crystals. Salt can also be briquetted cold but this does require a higher pressure level.
Thewater softener salt, also known as ion exchange resin regenerate. Which the mainingredient issodium chloride, is used to reduce the hardness of water (Calcium, magnesium and other water based impurities).It helps the water clean, keep the pipeline unobstructed and free of scale.
A lot of the salt briquette used for industrial boiler cause too much industrial boiler scale can cause explosion, It is also widely used in industry like electronic power industry, metallurgical industry, and medicine industry, chemical industry, food and beverage industry, hotels, restaurants, heating stations, pots furnaces, office buildings, cold storage, shopping malls, air-conditioning, etc.
Hydraulic roller briquette press machine plays a good role in softner salt briquette making. Its high pressure makes the briquette steady and a long service time for water treatment.It also has a large choice for the shape of the briquette salt and varies in capacity.
The animal mineral lick briquette or licking stone is used to supply a number of minerals for animals for optimal growth and reproduction.For all the animals which are fed in the farm, salt briquette is needed every day. Like the cows, they need it to make milk which contains a lot of sodium and chloride. When they dont have enough salt, they will lose appetite and weight. If this thing goes on, they even get odd materials such as dirt, rocks and wood to satisfy their instinctive taste for salt.
Hydraulic briquetting machine supplies a very big pressure for making all kinds of briquette include the animal mineral lick salt briquette. The briquette machine brings you briquette with uniform size and quality. The lick salt with high density wont break and with a long service life. These briquettes with the same shape and size are easily packed incartons to sell and transport.Get in Touch with Mechanic
