Mining machinery is a mechanical and equipment used directly for minerals and mining preparations. It mainly includes mining machinery mining machinery and non -metal ore mining machinery; coal mining machinery for mining coal; oil drilling machinery for oiling oil.Lets introduce it below!
What are the types of open -air mines
From the perspective of equipment level, my countrys open -air mineral equipment can be roughly divided into three types:
(1) Small mine equipment is single, small, and uncomfortable; some processes have been working on manual work so far.
(2) The degree of mechanization of medium and individual large -scale minerals is high, but the equipment is old and the efficiency is not high.
(3) A few large mines use imported or domestic modern equipment, such as dental rigs, electric wheel cars, Dourong excavators, high -power bulldozers, etc., forming a set of work lines, which is efficient.
Introduction to mining machinery
The first typhoon coal mining machine was designed by British engineer Walker, which was successfully manufactured in 1868; in the 1880s, hundreds of oil wells in the United States were successfully chisen with steam drilling;Drill oil wells and natural gas wells with a tooth wheel drill, and has been used for open -air mines from 1937.
What is the difference from the standard type
The length of the LRs arms is more than 8 meters long than the standard type, and the length of the hip rod exceeds 18 meters is nearly 6 meters than the standard, so the excavation radius reaches 34.7 meters (the standard type is 26.8 meters), but 19Cube of cubic meters of fighting less than half of the standard model!In terms of power, the power of the bucket and the rotary motor seems smaller than the standard.
The XPA version of 5700 has a fighting capacity of more than 60 square meters and a working weight of nearly 2,000 tons. It is the worlds largest double track shovel that has so far.
