There are many kinds of environmental problems. In sum, there are two kinds of them. One is original environmental problem caused by nature evolution or natural disaster, which is also called the first environmental problem. The other one is secondary environmental problem caused by human activities, which is also called the second environmental problem. Environmental problems can also be divided into two kinds, which are environment pollution and environment disruption. The operation rate of the mineral processing equipment made by Fote Heavy Machinery is high, which can be beneficial to our environment.
So far, the metal mining of our country has been struggling for energy conservation and increasing economic benefit. To crush more and grind less is our basic principle. The main advance of the crushing equipment is the research and application of the original and practical crushing equipment, such as the new-type jaw crusher, double-cavity jaw crusher, double-cavity rotary crushing machine, impact crusher, and so on.
In fact, with current technology and economy condition, few minerals can be exploited, processed, and utilized. Recently, the iron ores which can be processed by the domestic mineral processing equipment mainly are magnetite and hematite. Among them, in the output of iron concentrate in our country, the output of magnetite concentrate accounts for 3/4. Besides, most of the domestic iron ore processing technology revolution focuses on these two kinds of ores.
However, the high-pressure roller mill developed in our country, which can replace the fine crushing machines and the common coarse grinding machines, recently is being done the industrial test in mining. Besides, the cylindrical grinding machines have been applied to some mining in our country. It is of energy conservation, which can increase the output of the mineral processing equipment system by more than 30%-50%. And the operation rate of it is high, which only affects environment a little.
But, in recent years, the domestic iron ore processing technology has been improved because of the introduction of the advanced foreign equipment. Especially, we have introduced many new-type high efficient equipment in crushing, grinding, separation (including gravity separation, magnetic separation, flotation separation), dehydration, filtering, and so on. And they have been applied successfully, which offers the equipment guarantee to the improvement of the mineral processing technology.
