subject: Analysis Of Sand Aggregate Processing System [print this page] Sandstone aggregate processing system can be divided into two basic types of artificial aggregate processing systems and natural aggregate processing system, mainly near the main project of the source material to establish what form of sand and gravel aggregate processing system for the natural bone adequate source of feed material, and level with a more appropriate general use of natural sandstone aggregate processing system; insufficient natural aggregate material sources or source material sufficient graded big difference between the abandoned high capacity generally use artificial aggregate processing system.
The process of natural aggregate handle oversized or artificial aggregate of coarse crushing section, the general directly under stope incoming, its duration should be consistent with the stope harvesting system, the handling of oversized or coarse crushing (jaw Breakers) choice, its load factor is desirable from 0.65 to 0.75; screen wash (shaker) and broken (crusher), crushing (cone crusher) workshop in general two-class system, the desirability of its equipment load factor 0.75 0.85; rod mill sand, product gradation and stability, it is appropriate continuous three-shift work system, its equipment load coefficient can be 0.85 to 0.9.
Natural aggregate production process: oversized stone processing and gradation adjustment screening sand and gravel washing supplementary artificial sand Water Recycling and Sewage Treatment; lack of natural aggregate amount of sand or natural the gradation of the sand can be used to excess coarse aggregate sand to supplement or adjust the gradation. Artificial sand and natural sand are generally mixed in a rod mill, spiral classifier, can also be used in conjunction with stockpiling, respectively, in proportion.
Typical artificial aggregate production process: the semi-finished production gravel production sand Water Recycling and Sewage Treatment. Artificial aggregate of semi-finished products refers to the blocks (eggs) obtained after coarse crushing of stone raw materials, products, and the maximum diameter of the general control allow less than the maximum feed particle size in the crusher.
