黑龍江哈爾濱花崗巖破碎生產(chǎn)線案例深度報道
項目背景

哈爾濱賓縣賓西鎮(zhèn)作為黑龍江省省級改革試點鎮(zhèn)，充分發(fā)揮其得天獨厚的區(qū)位優(yōu)勢與礦產(chǎn)資源儲備優(yōu)勢：

礦產(chǎn)資源儲量豐富：石灰石（儲量約3億立方米）、建筑用石（儲量近3億立方米）、陶粒頁巖及黏土（總儲量超2億立方米）、鉛鋅礦（已探明儲量1.5億立方米）

交通物流便捷：毗鄰哈爾濱主城區(qū)，哈同高速、哈佳鐵路貫穿全境，大宗物料運輸好的
    產(chǎn)業(yè)政策支持：享受省級工業(yè)園區(qū)稅收優(yōu)惠及基礎(chǔ)設(shè)施配套補貼

2017年完成的破碎生產(chǎn)線升級改造項目，采用全套液壓圓錐破碎設(shè)備，成為東北地區(qū)首批實現(xiàn)智能化控制的現(xiàn)代化砂石骨料生產(chǎn)基地，年均供應(yīng)高品質(zhì)建筑骨料超200萬噸，服務(wù)周邊300公里范圍內(nèi)的高速公路、鐵路及商混站建設(shè)需求。
