Characteristics of river gravel:
River gravel's major chemical composition is silicon dioxide, followed by a small amount of iron oxide and small amounts of manganese, copper, aluminum, magnesium and other elements. River gravel with more silica will be harder to be broken. The user should be based on the use of the finished product to research the process configuration.
Use of finished product:
River pebble crusher is widely used in ceramics, precision casting, paper making, abrasion, chemical, monocrystalline silicon, defense and other industries, high-quality materials for highway and railway construction, water purification, sewage treatment, electricity, garden and other projects.
Development prospects:
China has many rivers, so abundant of river pebbles. In most parts, the river sand and gravel resources development are limited to the exploitation of river sand; river gravel crushing, grading comprehensive utilization has not been fully realized. In recent years, with the development of mining machinery , The upgrading of the river gravel Sand made the application of river pebbles more widely, not only used as a concrete aggregate but also road construction level stable layer material. The cost of river gravel mining is lower than blasting rubble, less impact on the ecological environment, and strong government support .Behind its huge potential for economic development, show a huge demand for gravel in the next few years, and investment River pebble sand will form a new investment hot spot.
Configuration program:
1. According to the hard nature of the river pebbles, it is recommended to use the laminating equipment and multi-stage crushing program. Multi-level laminating equipment (jaw crusher and cone crusher based) to maximize the reduction of wear and tear costs for wear parts, while reducing the anti-material after the screening, increase production capacity of the production line. If a production line in the ratio of product returning is too high, will make the final a crusher increase in the excessive and repeated broken, so that the wear loss will be greatly increased.
2. If the customers do not have high requirement for the grain shape of finished stone, you can use the solution of the two broken jaw for production. This configuration is the minimum investment, minimum program of maintenance costs, production costs are the most economic of all programs; However, the disadvantage of this program is the grain shape of the stone is relatively poor, a higher proportion of elongated materials, and the competitiveness is not high in the market, hard to reach the high-grade building grain requirements.
3. If the customer requirement is excellent grain type, and reduce production costs, can use two laminated crusher (jaw crusher + fine broken jaw / cone crusher) and crusher supporting technology programs. This configuration allows the main breakers work from beginning break and second break to complete (laminated broken), then Integer broken by the impact crusher, it can greatly reduce the formation of product returning after screening. If we use jaw crusher impact crusher process configuration, the wear speed of impact crusher's wear parts will be very fast, production costs will increase a lot.
