玄武巖破碎制砂方案的工藝設計一般采用多層破碎方案，該方案實現了砂石同出，能效高，廢料少，低污染，成為主流工藝設計。

1.在好的個破碎步驟中，選擇顎破。顎破給料粒度大，破碎能力強，可一次性將大塊玄武巖破碎至中等粒度。

2.鑒于玄武巖硬度高，二次破碎需要圓錐破碎設備。為了提高破碎效率，可以多增加一道破碎工序，單缸液壓圓錐破碎和多缸液壓圓錐破碎相結合，可以打破玄武巖破碎產量低的瓶頸。

玄武巖是一種基性噴出巖，其化學成分與輝長巖或輝綠巖相似，SiO2含量變化于45%～52%之間，K2O+Na2O含量較侵入巖略高，CaO、Fe2O3+FeO、MgO含量較侵入巖略低。礦物成份主要由基性長石和輝石組成，次要礦物有橄欖石，角閃石及黑云母等，巖石均為暗色，一般為黑色，有時呈灰綠以及暗紫色等。呈斑狀結構。氣孔構造和杏仁構造普遍。

玄武巖，是生產"鑄石"的好原料。"鑄石"是將玄武巖經過熔化鑄造、結晶處理，退火而成的材料。它比合金鋼堅硬而耐磨，比鉛和橡膠抗腐蝕。玄武巖還在一種鑄鋼先進工藝中，起到"潤滑劑"的作用，可以延長鑄膜壽命。同時，玄武巖還可以抽成玻璃絲，比一般玻璃絲布抗堿性強，耐高溫性能好。

玄武巖是修理公路、鐵路、機場跑道所用石料中最好的材料，具有抗壓性強、壓碎值低、抗腐蝕性強、瀝青粘附性玄武石，玄武石具有耐磨、吃水量少、導電性能差、抗壓性強、壓碎值低、抗腐蝕性強、瀝青粘附性等優點，并被國際認可，是發展鐵路運輸及公路運輸最好的基石。

玄武巖是一種相對堅硬的石頭。由于其抗壓能力強、壓碎值低、抗腐蝕性強、瀝青粘附性好，在國際上被公認為是用于修建公路、鐵路和機場跑道的石料中的優良材料。不僅如此，玄武巖還是高層建筑輕質混凝土的更好骨料。由于其多孔、堅硬的特性，將其摻入混凝土中，可以減輕混凝土的重量，但卻很牢固。同時還具有隔音隔熱的優點，受到各大建材市場的青睞。
