Wear-resistant composite materials promote industrial efficient production Investment potential remains to be tapped
Mineral resources are an important material basis for national economic and social development. According to the statistics of the Ministry of Land and Resources, China's solid ore mine output increased from 5.2 billion tons in 2005 to 9 billion tons in 2010 during the “Eleventh Five-Year Plan” period, a net increase of 3.8 billion tons; iron ore production from 21,701 in 2001 Ten thousand tons increased to 1,306.73 million tons in 2012. with an average annual growth rate of 19.69%. According to the "National Mineral Resources Planning (2008-2015)" issued by the Ministry of Land and Resources, in 2015 China's iron ore mining volume will reach more than 1.1 billion tons, copper ore will reach more than 1.3 million tons, and lead and zinc will reach 7 million tons. the above.
In the mine ore mining and beneficiation process, the hammer head of the crusher, the teeth of the boring machine, the lining plate and ball of the ball mill, the steel wire rope and the liner of the hoisting machine, and the blades of the ventilator are all parts that are easy to wear. These worst-wear parts are also where wear materials are most needed.
In 2009, China's iron ore consumption ball mill wear-resistant material is about 1.2 million tons, non-ferrous metal ore consumption ball mill wear-resistant material is about 275,000 tons; in 2011, China's iron ore industry crushed ore consumption of ball mill wear-resistant material is about 148 Million tons; alumina industry crushing bauxite ball mill wear-resistant material is about 32,000 tons.
