B9000型破碎机的特性及在人工砂生产中的应用

Characteristic of Crusher Model B9000 and Its Application in Artificial Sand Production

随着我国基础设施建设的持续发展和对环境保护的重视，现有的天然砂资源已不能满足工程需要，使用人工砂已成为今后的发展趋势。在传统的砂石料工厂，生产出＜５ｍｍ的石屑呈尖角、粒型差、针片状多，传统混凝上行业、沥青行业不采用这些人工砂。寻找生产成本低、产品质量好的人工砂生产工艺和性能可靠的设备已势在必行。

Natural sand source in China hasn' t met the need of construction engineering with continuous development of fundamental construction engineering and environment protection. It is development trend to use artificial sand. The sands and stone chips with size < 5mm produced by traditional stone factory are always sharp angle, needle shape and thin piece. They can' t be used in asphalt industry. It is unavoidable to find out low cost and reliable equipment to produce the best quality artificial sand.
