First, the application of river pebbles
River gravel is a hard, wear-resistant, chemically stable natural stone, very high value. Rich river gravel resources, not only stored in the river, the hills have their presence. Natural river gravel crushing, sand, and other series of production after screening processed into gravel aggregate, it can be widely used in water utilities, highways railways, bridges, airports, municipal engineering, high-rise buildings and other projects and concrete Mechanism aggregate sand and stone shaping production.
Second, the river gravel production technology
1. The material is fed into the jaw crusher for primary crushing;
2. After crushing of materials transported by conveyor to a crusher crushing second job;
3. After crushing the material into the shaker, the separation of the two stones of different size requirements;
4. Sand to meet the size requirements of the feed into the crusher sand stone, the other part is returned crusher again broken;
5. After entering the Sand stones made of sand, then sand Jingxi sand cleaning of finished products.
Third, the river gravel crusher
Commonly used in river gravel crushing equipment production line of jaw crusher and impact crusher.
1. jaw crusher commonly used in river gravel crushing part of the first stage, the major works by the movable jaw and static jaw two jaw plate crushing chamber to simulate the movement of animals two jaw crusher complete material crushing operation machine. Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and bulk materials of medium-grained broken. The maximum compressive strength of the material to be broken for 320Mpa.
2. The crusher is used for crushing river gravel second stage segment, is a new high-efficiency crushing equipment, small size, simple structure, broken, less than the energy consumption, production capacity, uniform particle size and other features, and selectively crushing effect. But the device back plate special hammer and easy to wear, especially crushing hard ore, wear is more serious, need frequent replacement. The use of new wear-resistant materials to extend the service life of back-breaking.
