可以。天然砂、水洗砂、機(jī)制砂有何區(qū)別?用什么制砂設(shè)備加工生產(chǎn)好?
機(jī)制砂可以利用各種尾礦、建筑廢棄物制砂,受到國家和各地政府的支持。 機(jī)制砂系統(tǒng)是根據(jù)市場需求并結(jié)合國內(nèi)外生產(chǎn)技術(shù)和多年生產(chǎn)經(jīng)驗(yàn)設(shè)計(jì)研發(fā)的干式骨料優(yōu)化系統(tǒng),結(jié)合各類礦石的品質(zhì)，構(gòu)建生產(chǎn)線系統(tǒng)，機(jī)制砂經(jīng)水洗后也成為水洗砂，品質(zhì)更佳，含泥量更低。天然砂以河沙為主，海砂黃河面砂等不符合相關(guān)規(guī)范。加工機(jī)制砂一般選擇制砂機(jī)，如vsi，pcl制砂機(jī)等，也可以選擇顎破或者反擊破來小批量生產(chǎn)機(jī)制砂。

固廢變砂,黑龍江省兩項(xiàng)涉及尾礦機(jī)制砂地方標(biāo)準(zhǔn)公開征求意見
1月10日據(jù)悉，黑龍江省市場監(jiān)督管理局發(fā)布2023年黑龍江省地方標(biāo)準(zhǔn)公開征求意見，此次公開征求意見的標(biāo)準(zhǔn)中兩項(xiàng)涉及采石尾礦機(jī)制砂，分別是《采石尾礦機(jī)制砂質(zhì)量及檢驗(yàn)方法標(biāo)準(zhǔn)》及《采石尾礦機(jī)制砂混凝土砂漿應(yīng)用技術(shù)規(guī)程》

三明 南平 龍巖等福建省資源型地區(qū)如何發(fā)展?機(jī)制砂石來助力
機(jī)制砂由人工開采的巖石經(jīng)機(jī)械破碎、篩分而成，利用其替代天然砂，既環(huán)保又經(jīng)濟(jì)。2022年度福建省重點(diǎn)項(xiàng)目名單中就包含有多個(gè)機(jī)制砂石項(xiàng)目：龍海建筑用碎石及尾礦機(jī)制砂項(xiàng)目、福能新材華安機(jī)制砂項(xiàng)目、永安宏億建筑用機(jī)制砂生產(chǎn)項(xiàng)目、邵武市朱山礦區(qū)建筑用花崗巖礦（機(jī)制砂用）生產(chǎn)基地項(xiàng)目等多個(gè)項(xiàng)目。
 
鐵尾礦砂和機(jī)制砂復(fù)摻制備高性能混凝土
鐵尾礦砂不同摻量對(duì) C30 高性能混凝土抗壓強(qiáng)度影響的試驗(yàn)結(jié)果見表。 從表可以看出,隨著鐵尾礦砂摻量的不斷增加，C30 高性能混凝土的柔和性先逐漸變好而后逐漸變差，流速先逐漸變快而后逐漸變慢，黏度由差變好后變大，石子包裹性由差逐漸變好，含氣量變化不大，都在 2.0%~4.0% 之間（正常范圍內(nèi)）。綜合鐵尾礦砂與機(jī)制砂復(fù)摻對(duì) C30 高性能混凝土工作性能（柔和性、流速、黏度、石子包裹性等）和含氣量的影響，鐵尾礦砂的最佳摻量應(yīng)控制在 15%~25% 范圍內(nèi)。

2022年濟(jì)南市機(jī)制砂產(chǎn)品質(zhì)量市級(jí)監(jiān)督抽查結(jié)果機(jī)制砂是以巖石、卵石、礦山廢石和尾礦等為原料，經(jīng)除土處理，由機(jī)械破碎、整形、篩分、粉控等工藝制成的，集配、粒形和石粉含量滿足要求且粒徑小于4.75mm的顆粒。
