We are know, regardless of is building also is road and bridge building, cannot be separated from gravel aggregate of application, but they for stone has himself of requirements, is not as long as broken Hou on can reached standard of, stone of quality include two a aspects: a is resources characteristics is gravel of mechanical strength, durability, and chemical stability, surface characteristics and the is exists bad impurities,, according to technology specification asphalt surface layer with rough set material should meet of quality requirements; II is processing characteristics, main include particles size and level distribution, and particles shape, and Consistency of the particle size, cleanliness and 0.075mm particle concentration, and so on. After General Crusher stone, its needle Flake particle more, unable to meet the needs of concrete stone, does not meet its standards, and by a new stone shaping features for VSI sand making machine processing, full compliance. Freeway pavement construction in our country from the mixture, spreading to rolling by adopting advanced production equipment, achieving mechanical construction, only raw materials are still in the backward situation. Emergence of sand and stone processing technology has taken a big step forward, currently on the crushed stone production not only in quantity, quality requirements meet Expressway construction, but also to meet the demands of mechanization construction.
Vipeak Heavy industries launched production of new type VSI sand making machine is the use of high-speed movement of materials between themselves broken and the friction between material pieces. Passed "stone stone" "stone blacksmith" two broken forms, reducing needle flake, the stone to achieve standards available, widely applied metal and Nonmetal ores, materials, artificial sand and various metallurgical slag crushing and shaping, meet strict control of needle Flake purposes
