Abstract

The invention relates to a high pressure gas fragmentation iron ore test device. The high pressure gas fragmentation iron ore test device comprises a steel drum, a first flange, a second flange, a seal flange, an anti-explosion disk, an annular plate, a connecting rod and a high pressure gas tank. Two ends of the steel drum are provided with the first flange and the second flange respectively. The seal flange is arranged on the second flange, the anti-explosion disk is arranged between the second flange and the seal flange, the annular plate is arranged between the second flange and the steel drum, and the annular plate is connected with the second flange through the connecting rod, so that an inflation cavity is formed between the annular plate and the second flange. The high pressure gas tank (not shown) is connected with the steel drum 1 through a high pressure gas delivery pipe. According to the high pressure gas fragmentation iron ore test device, the characteristics of high density and low viscosity of high pressure gas fluid are utilized, so that the high pressure gas permeates the inside of the iron ore through joint or microcrack of the iron ore itself, and the iron ore containing the high pressure gas generates fracture and fragmentation under high pressure gradient through sudden pressure relief. The high pressure gas fragmentation iron ore test device has an important realistic significance for reducing the crushing cost of the iron ore and improving economic benefits of an enterprise.

Description

technical field [0001] The invention relates to a high-pressure gas crushing iron ore test device. Background technique [0002] my country is rich in iron ore resources, but the iron content is low. Mined ore needs to be processed before it can be smelted. A very important process in the beneficiation process is to carry out coarse crushing, medium crushing, fine crushing and grinding of the blasted ore. The current technology is to use a mechanical crusher to crush the ore. Mechanical crushing requires a lot of electric energy and the wear of mechanical parts (especially the lining plate) is also serious. The average cost of ore pulverization is more than 200 yuan per ton. Therefore, a new ore crushing and pulverization technology and device is proposed, which can save the cost of mineral processing for iron and steel enterprises, and can greatly improve the competitiveness of our country's enterprises. [0003] The crushing and fragmentation of iron ore under high pres...
