For the waste stone generated by the mine, the utilization rate is very low.Only iron ore resources, because the recycling rate is too low, lose at least hundreds of billions of yuan every year.In many open-pit mines, the amount of waste stone produced every year is huge, and it is basically piled up in the waste stone field, which has caused a large amount of land to be occupied, which is a very serious waste.And waste stone itself is a kind of resource, not only has it not been well used, but it has also become a source of pollution, which is a pity.
Mine waste stone becomes rich sand and gravel in seconds
Mine waste stone is mainly divided into main rock and surrounding rock. The mine waste stone is broken and processed into sand and gravel aggregates. The sand and gravel production line is used to break the mine waste stone into round stones of standard size and shape, and the mine waste stone is reused. It not only saves land resources, reduces environmental pollution and damage, and can solve the sand problem in the sand and gravel industry, which well reflects the main thrust of resource recycling in a conservation-oriented society and an environmentally friendly society.
1. Crude concrete aggregate. As an important raw material for concrete, sand and gravel aggregates, due to the use of aggregates processed from mine waste stones, the utilization rate of mine waste stones has been improved, pollution has been reduced, and the shortage of concrete materials has been solved. The problem.However, not all mine waste stones can be used for coarse aggregates. The physical and chemical composition of the rocks need to be considered, as well as the degree of weathering and the degree of fracture development.
2. Railway/highway slag. Railways require a considerable amount of road slag, and many mine waste stones can be broken into stones to be used as railway road slag, such as limestone, basalt and other ore materials.Compared with railway road slag, highway road slag has lower requirements for waste stone, so waste stone is more widely used in highway road slag.
3. is used as a raw material for cement. Adding an appropriate amount of mixed materials to cement can not only improve certain properties of cement, but also save material consumption. At present, blast furnace slag and fly ash have become commonly used cement active mixed materials, as well as some tailings. The same is true.
Mine waste stone processing production line
When processing waste stone, the selection of equipment is very important. If you want a good finished material, you must make a reasonable equipment configuration. The waste stone production line of Liming Heavy Industry is mainly composed of feeder, crusher, vibrating screen, conveyor and other equipment.The waste stone material is transported by the feeder into the cone break for the initial crushing, the coarse broken aggregate is transported by the tape conveyor into the cone break for the secondary crushing process, the broken aggregate is sieved by a vibrating screen, and the aggregates that meet the requirements of the finished material are transported into the finished product pile, and the aggregates that do not meet the requirements are returned to the cone break for crushing again.
The crushing equipment adopts a new type of production technology, which is high-efficiency, energy-saving and environmentally friendly, and has the advantages of large crushing ratio and rounded grain shape of the finished product. The cone crusher is the best choice for the production and processing of sand and gravel aggregates.If you are interested in our products or have any questions, please feel free to call us at any time 0371-67999188 or click“ business Through ” For consultation, our customer service staff will provide you with detailed answers and thoughtful service.
