In 1955, Russell and Einstein published the famous "Russell-Einstein Declaration", and eleven famous scientists signed the signature, including ten Nobel laureates, including Bonn, Jolio Curie. Wait. The Declaration warned that the outbreak of nuclear war would bring devastating disasters to mankind and called for restrictions on the research and use of nuclear bombs. However, the scientists who published the "Declaration" at the time did not seem to expect that the nuclear bomb, a tool that was originally used as a weapon, would be used peacefully.
Several countries have carried out peaceful applications of nuclear explosions. The Soviets have fully exploited the characteristics of the daring of the fighting nation and opened their minds. First, they applied nuclear explosions to the mining of mines. If the conventional ordinary explosives are mined and the 1 million tons of ore rock is crushed, it is necessary to excavate the roadway of 2 to 4 kilometers, drill a well of 10,000 meters deep, and use 50 to 600,000 tons of explosives. The cost is about It should account for 30% to 40% of the value of minerals. If a nuclear explosion is used, it will save money and save time.
Nuclear explosion mining saves time and money compared to explosives. If the explosives are used to crush tons of ore rock blocks, it is necessary to drill a kilometer roadway, drill a 10,000-meter-deep well, and put tons of explosives. The value consumed is about 30-40% of the mineral value. If a nuclear explosion is used, it will be much more economical.
In 1969, the Soviet Union conducted a test evaluation of the technical possibilities and economic rationality of using nuclear explosions to crush ore. They conducted two tests in the ore section of the ore body about 30 meters in length and more than 200 meters in length in the northern part of Kirovsk.
In 1972, a single-head nuclear explosion with a power of about 2.1 kilotons was carried out, and the volume of the crushed ore section was 50×50×50 meters;
In 1984, a double-warhead combination explosion of 75 meters was carried out, each of which was 1.8 kiloton equivalents, the crushed ore section reached 50 x 125 x 90 meters, and the amount of crushed ore exceeded 1.55 million tons.
The engineering test evaluation proves that it is technically and economically feasible, and the seismic and radiation effects are also safe. Because of the thousands of tons of nuclear explosions, the seismic waves are not strong and are not far away; nuclear fuels are used sparingly, and radioactive products with a long half-life are left less, and the effects of radiation are even smaller in a large amount of ore and soil.
If the Soviet Union is still a test, then Australia can be practical. In the development of famous Australian Pilbara iron ore, on the use of the bomb blast assist.
SR series Single shaft shredder is a crushing machine with perfect design. It`s wide used and qualified to shred various waste materials such as plastic block & pipes, woven bags, cable, wood, paper, domestic rubbish, electronic waste and so on. The suitable screen can be chosen according to fed materials and the next processing requirement. The output material discharged by the shredder could be directly reused or further shred into small pieces. SR series shredder can be equipped with many different rotor and its rotor process requirements of cooling system, bead weld & wearing layer can also be additionally added according to customers` requests for disposing various waste materials.
