在河卵石砂石骨料廠中，給料機將河卵石送入顎式破碎機進行破碎。顎式破碎機是將河卵石粉碎成小粒度，圓錐破碎機是將河卵石二次破碎，制沙則選擇vsi系列的河卵石制砂機設備。

河卵石是一種純天然的石材，取自經歷過千萬年前的地殼運動后由古老河床隆起產生的砂石山中主要化學成分是二氧化硅，其次是少量的氧化鐵和微量的錳、銅、鋁、鎂等元素及化合物。內含有小石子的卵石，其形成原因是破碎的巖塊，經長距離搬運使棱角消失，形成園形或橢圓形的石子（或稱卵石、礫石），再經膠結的巖石稱為礫石。天然顏色的機制河卵石、雨花石、干粘石、噴刷石、造景石、木化石、文化石、天然色理石米等建筑裝飾材料及室內裝飾用的高級染色沙，無毒、無味、不脫色。品質堅硬，色澤鮮明古樸，具有抗壓、耐磨耐腐蝕的天然石特性，是一種理想的綠色建筑材料。河卵石指像卵一樣的石頭，不論大小。小的如谷粒，大的如西瓜或更大。河卵石完全是自然形成，不存在人工機制問題。河卵石由于地殼的變遷，也不是僅僅存于河道，在丘陵地帶同樣有他們的身影。

河卵石，是一種質地堅硬、耐磨、化學性質穩定的硅酸鹽類礦物，天然的河卵礦石經過破碎、制砂、篩分等一系列加工之后生產成河卵砂，河卵砂是重要的工業礦物原料。

 
河卵石破碎后能用作混凝土嗎?
可以，一般作為沙子加入混凝土。河卵石硬度高，但原料粒度不大，河卵石破碎可以直接用顎式破碎機和制砂機完成破碎制砂。顎式破碎機作為一種適合破碎卵石的設備，主要用于卵石的初級破碎作業，制砂機用來將更碎的石子制成沙子。河卵石制成的砂石骨料廣泛用于工程領域的水利水電、好的級公路、高速公路、高速鐵路、客運專線、橋梁、機場跑道、市政工程、高層建筑的機制沙生產和石料整形。河卵石成砂還被廣泛的用于作為混凝土的骨料。河卵石資源豐富，采集成本相對較低，應用價值高。
 
河卵石移動式制砂機效果如何？
1、經過河卵石移動式制砂機加工后的成品石子，和固定式設備成品基本一致，無明顯差別；2、河卵石移動式制砂機因其移動式和整體裝配式設計，可縮短施工周期和更換作業場地。

河卵石圓錐破碎機在河卵石制砂生產線的應用
河卵石圓錐破碎機將河卵石破碎的成品，明顯具有顆粒優勢，相對石子較圓，適應更高要求的高鐵等市場，成品優勢明顯，成砂率高，廢粉率低。

山東河卵石制砂生產線
山東河卵石制砂生產線一般由顎破，vsi制砂機和篩分設備組成，將河卵石先破碎，然后經vsi制砂機制砂處理，加工成機制砂，目前山東石子制沙主要設備由vsi系列制砂機構成。

河卵石破碎可以使用移動破碎機嗎
可以！河卵石破碎技術河卵石破碎最大的問題是耐磨件容易磨損，因為河卵石中的硅含量很高，這樣我們選擇針對石料破碎難度大專門改善的圓錐破做主機，選擇移動圓錐破碎生產線即可。

河卵石破碎了可以當砂用嗎?河卵石制砂生產線介紹
可以用。河卵石作為一種天然綠色的砂石生產原料，只要經過合理的流程加工，河卵石機制砂完全能滿足粒型完整、粒度均勻、等各項標準，因其主成分為硅，所以品質相當高。
