GM Series high-pressure grinding roller (HPGR) is a new type of equipment developed by applying advanced crushing theory and adapting to the characteristics of metal ores. It is widely used in the crushing process of pellets and various mines, especially in iron, manganese, copper, gold, diamond and other metal mines.
Explain. High pressure roller mill (HPGR) technology is gradually becoming a common grinding tool in iron ore processing. This technology has been widely accepted in the closed-circuit grinding of coarse ore grinding and feed preparation of ball mill, and has shown unique benefits, all the way to the other end of the particle size spectrum of iron ore pellet feed preparation.
High pressure grinding roller (HPGR) has been used for grinding pellets for more than 20 years. In addition to coarse comminution (comminution), HPGR is installed upstream of the ball mill, and there are many flow charts, in which HPGR is used for regrinding or fine grinding after ball milling and dehydration. There is a clear...
The cruf gold mine is one of the largest gold deposits in South Africa. On October 7, 2015, working in the mine at an altitude of 14800 meters, the number of employees was 14800. Since the venterspost mine was put into operation in 1939, the Kloof complex has processed nearly 250 million tons of ore, with an average output of 9 g / T and more than 710 million ounces of gold.
The final feed of HPGR grinding, sobythe HPGR, runs again in the closed circuit of the 8 mm screen. The raw materials were prepared by two-stage crushing method. The feed size was initially 25 mm, but increased to 35 mm after extended operating time. The total amount of HPGR treatment was 188000 TPH, and the final product was 115000 TPH until the final product reached...
HPGR grinds the final feed. The particle size and shape of iron ore pellet feed were studied by ball mill and HPGR 909. Therefore, it is necessary to regrind the concentrate area of 5001600 cm2 g1he to prepare suitable pellet feed. High pressure grinding roller and ball mill are the most widely used.
