Gravel crushing production line commonly used method

Former White Mercury Mining Process production line operations, the mountain broken ore needs to a certain size. By a variety of transportation equipment shipped to the job site gravel production line. Different ore crushing stone molding method may cause problems, ore crusher manufacturers to choose the correct method is particularly critical. The first explosion broken using dynamite or other explosives tremendous energy released instantaneously crushed rock, currently the most widely used and most effective. Second, mechanical crushing, sub-cutting, caulking, crushing, grinding four ways. When broken rock, rock-breaking tool into the rock, the rock movement of the tool in front of the body, appears dense core. In dense nuclear generating chipping body around larger pieces. Mechanical crushing hard rock not widely applied in the main reason is a serious tool wear. The wear depends on the degree of the hard rock minerals (mainly quartz) content and particle size.

Third, water jet broken, Talc Powder Machinery Production divided low pressure high flow and small flow of two high pressure. The former pressure does not exceed 2 × 107Pa, used for hydraulic mining or mining; the latter pressures up to hundreds of millions of Pa (Pa) or more, used to cut rock. It also developed a pulse jet technology, can effectively crush solid rock without great power. The highest instantaneous pressure has reached 5.6GPa. High-energy high-pressure water jet breaking rock, mechanical structure is more complex, as the current multi-boring machines and open-air rotary drill broken rock adjunct. Fourth, thermal broken rock formation in vivo in a high temperature gradient, and use each component of the thermal expansion coefficient different rocks, the formation of thermal stress, the rock crushed flake or crisp. Quartz containing rocks make this method more effective. Modern heating methods thermite, flame spraying, plasma flame, microwave, infrared radiation, high-energy electron beam, a strong breakdown current, laser. But in addition to the flame spraying method (fire drill), other are in the experimental stage.

Firstly, according to Bentonite Mining Processing Plant mining conditions, proper arrangement of mining engineering; determining ore mining process, including the approach layout and mining sequence, filling materials and ratio, rock blasting process. After mining approach, square into the filling stage of preparation. After a review of data we found that the best way is to take effect filling direction several times along the route is filled, then the filling into the road to ensure top. Filling the preparatory work to do before filling stope, including erection of the filling, the exhaust pipe, build retaining wall filling. In order to increase the rate of filling the top pick, the process has taken the following measures: 1, after filling the slurry flow has slope 3 ° ~ 5 ° of about 1 this filling into the path length control in less than 15m, 30m above approach to implement more point cutting; cutting tube to pick up at the top of 0.5 ~ 1m, filling pipe erected at the intersection into the highest point from about 8m to ensure filling top pick; 2, by adding naphthalene superplasticizer increase the filling concentration, get higher then the top rate, reducing the displacement.

Generally speaking, when to use the mining equipment vibrating feeder, jaw crusher, impact crusher, cone crusher, impact crusher (sand making machine), vibrating screen, ball mill, high frequency screen, Jigger, bucket elevator and other equipment. In the quarry aggregate processing production, crusher, sand making equipment are not usually used alone, but with a reasonable, designed to be combined into a production line of stone or sand production line, sand and gravel together to complete efficient production. The major production processes are required to use a suitable mechanical equipment, in order to obtain the best economic results.
