The Development of Mining Machinery

2010-12-17
 

The mining machinery industry is highly dependent on mining activity in the China and the world. When demand for mined materials is high, mine operators order new machinery; when demand is low, orders fall off. Mining machinery manufacturers are cushioned somewhat from demand cycles because different kinds of mines use similar machinery. Thus a decline in coal mining, for example, may be offset by a boom in salt mining.

The market share divisions within this industry were split among several categories. Underground mining machinery claimed 30.9 percent of the industry in 1997, up from 15.4 percent in 1995. In 1997, crusher mill, pulverizing, and screening machinery held 21.6 percent of the market, a jump of over 10 percent from 1995. Drills and other mining machinery, not elsewhere classified, controlled 5.3 percent of the market, down from 9.4 percent two years earlier. The remaining categories accounted for the other 42.2 percent.

The mining machinery industry draws its supplies from a variety of sources. Mill shapes and forms made from carbon alloy, stainless steel, copper, and aluminum are the most highly consumed materials. Castings from gray and malleable iron, steel, aluminum, and copper, and forgings from iron and steel are also heavily consumed. Fabricated structural metal products, speed changers, gears, industrial high-speed drives, and roller bearings constitute other significant materials consumed by the industry.
