Material analysis:
River gravel is a natural stone, the main chemical composition is silicon dioxide, followed by small amounts of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. They have different colors, such as red for iron, copper blue, purple is the manganese, the yellow translucent for the silicon dioxide colloid chalcedony, Emerald color contains green mineral and so on.
River pebbles in the process of breaking the biggest problem is wear-resistant parts subject to wear, this is because the content of Silicon in river pebbles are very high. With river pebbles stone as raw material plant, crushing process must be carefully studied. As Crusher manufacturer, in the case of customer conditions allow, we recommend as much as possible using laminating equipment and multiple broken package. Multilevel laminating equipment (mainly by broken jaw and cone Crusher) to maximize the cost of reducing the wear of wear parts, and can reduce the screen anti-to increase production capacity of.
Broken design team:
If customers don't depend on type of finished stone high levels broken jaw programme can be used for production. This is the lowest investment, maintenance and repair of the simplest solution, production costs are also the most economical in all programmes. However, the disadvantage of this scheme is the type of stones are relatively poor, higher percentage of needle and plate materials, which leads to the stone's not competitive in the market, because a number of high level architecture needs type excellent stone.
excellent for required product particle size, also hope to reduce the cost of production of the customer, we recommend to use two laminated Crusher (broken jaw + fine broken jaw and cone crushers) and impact crusher support process. This configuration allows the main fragmentation header break completed and two broken (broken laminated), only integer by the counter broken broken. This configuration allows the main fragmentation header break completed and two broken (broken laminated), only from counterattack broke the whole type broken, formed after this configuration process can greatly reduce the screen back. If a production line in the material too high, will make the last crusher is increased too much repetitive breaking work, also makes the wear parts of the corresponding losses will increase significantly.
River gravel as raw material for stone materials factory, if only with broken jaw and back breaking process configuration, then wear of wear parts of the back breaking speed is very fast, the production cost will increase a lot. Therefore, as Crusher manufacturer we do not recommend the use of the process.
