The coal briquetting machine is used to press materials with little water content including coal, mineral powder and refractory matter.
High pressure grinding mill has high-pressure springs inside, which can improve the grinding powder to 1.2 times higher. If roller ring is worn out, we can adjust the length of springs to keep the grinding pressure.
Jaw crusher machine, also named jaw crusher for short, is the earliest crusher.
The Compound cone crusher(Symons cone crusher) is suitable for crushing materials with medium hardness or above.
The mineral powder enters the furnace directly by enhancing its added value.
Different ores have different magnetic coefficients. Magnetic separator is just the machine that uses magnetic and mechanical power to separate the ores from mixers.
Lime briquetting machine is also known as lime briquette machine, lime pressure ballmachine, or lime ball press machine.
Superfine Grinding Mill fine grinding is a new product with high technical level developed by our company for the development of the grinding industry, absorbing the new grinding technology and concept at home and abroad.
ABSTRACTThe energy sector in India is highly dependent on coal as a fuel. At present, most of the domestically produced thermal coal is burned raw or after minimal beneficiation. This practice often results in higher operating and maintenance costs, poorer utilization efficiencies, and increased greenhouse gas emissions. To improve the prevailing conditions, the Government of India is taking ...Read More

IGCC plants can be configured to facilitate CO 2 capture. On average, IGCC plants produce CO2 at a rate of about 1.85 lbkWh, while the conventional pulverized coal-fired power plants yield about 2 lbkWh. 3 However, with an IGCC plant modified to produce hydrogen, a CO2 discharge rate of 1.2 lbkWh may be able to be achieved. 3Read More
