中国水泥网年会砂石骨料专场

  随着国内天然砂石资源的枯竭和禁采,基建和房地产的投资加大对砂石骨料需求旺盛的情况下,机制砂石行业迎来了发展机遇。水泥企业由于具备矿山、资金等方面有着先天的优势,近年来水泥行业进入砂石骨料行业日益增多。但是同时我们也发现,水泥企业在进入砂石骨料行业依然存在着大量的问题,这些问题有些是自身局限性造成的,也有观念上造成的。为此,中国水泥网特在“2017中国水泥网年会暨百强榜TOP100颁奖典礼”期间设立了“砂石骨料技术研讨”专场。

中国联合水泥集团总工程师袁亮国

  中国联合水泥集团总工程师袁亮国在报告中表示,目前我国砂石骨料生产线存在规模极其不合理和环保标准不达标等问题,微型、小型产能占83%以上,很多小砂石没有配备应有的收尘设备。但大型骨料生产线又存在工艺流程复杂、扬尘点多(收尘器多达10—15台)、投资高、占地面积大和设备维护费用高等缺点。如何解决这些问题需要更多业界同仁的的智慧和参与。

枣庄鑫金山智能机械股份有限公司总经理裴尚

  枣庄鑫金山智能机械股份有限公司总经理裴尚认为,砂石行业“大”时代已经来临。随着国家对基建的不断投入,市场对砂石骨料需求加大。但同时,政府对砂石骨料线的环保要求愈加严苛,矿山资源不断整合、关小并大的情况下将倒逼砂石骨料行业转型升级。与此同时,大型集团公司进军骨料市场,也将促进行业加快转型升级的进程。

  裴尚表示金山机械行业首倡“一机多用”理念,是指一个破碎主机多种用途,不仅可以用于大型骨料生产线生产骨料,而且可以替代水泥行业的传统破碎设备,节能降耗,降低生产成本,提高效益。将原主机产能加大2-3倍,大幅改进主机内部筛板结构,改造后生产线所生产的混料“质量”大幅提升,生产能耗降低了40%,可同时生产待磨粉原料及骨料,所产细碎原料与石粉供水泥厂内部使用,所产优质骨料对外销售,同时预留机制砂模块接口,以备后期上马机制砂系统。

伟尔矿业(中国)技术部经理付洛林

  伟尔矿业(中国)技术部经理付洛林认为,砂石骨料基地的规划首先需要政府行业策划,合理科学布局;其次,资源综合利用方面要避免环境破坏并且结合市场需求,合理建设规模,鼓励市场竞争,健全行业自律。此外,他还倡导绿色环保杜绝环境污染,扶植优秀企业淘汰劣质公司。

  此外,付洛林还说伟尔矿业所倡导的模块化技术就是将工艺相关的料仓、给料、破碎、筛分和皮带机整合在一起,将这些设备设计在一个组合式钢结构上。所有钢结构在工厂里预组装,全部是螺栓连接,非常便于现场的安装。标准化模块机组,可大幅度的降低现场土建投资、减少建设和调试时间。

枣庄市瑞隆机械制造有限公司总经理李士强

  枣庄市瑞隆机械制造有限公司总经理李士强介绍说,瑞隆重工精品砂石骨料生产线采用一级破碎方式就可以实现传统生产线两级破碎方式的生产方式,免去了购买至少一台设备款,也可以节省相应的土建费用,成功的解决了一些水泥企业资金不足场地限制等问题。

成都大宏立机器股份有限公司销售总经理周杰

  成都大宏立机器股份有限公司销售总经理周杰认为,目前砂石行业普遍还存在着企业平均规模小、产业集中度低、成品质量参差不齐、工艺落后、配置不合理、污染严重、生产安全防护措施不到位等问题,而这些正是水泥企业进军砂石骨料产业的巨大机遇。

  周杰还表示砂石骨料行业对破碎、制砂设备的要求主要是工艺先进、选型合理、配置得当;产能稳定,连续作业能力强;砂石骨料产品粒形好,质量好;生产运营成本低;智能化程度高、操作简单、维修维护少和噪音低、安全、环保。周杰对新型PEV颚式破碎机、单缸液压圆锥式破碎机、反击式破碎机、锤式破碎机、立轴冲击式破碎机和高压辊磨机等破碎、制砂设备进行了介绍。

天津水泥工业设计研究院教授级高工谢宪中

  天津水泥工业设计研究院教授级高工谢宪中表示,水泥企业生产砂石骨料具有资金、资源、矿权、管理、降本、利废的优势,但也存在一些局限性的问题和应该注意的地方。比如,水泥企业的砂石骨料生产线的布局受到石灰岩分布的制约,少数水泥企业用于制作砂石骨料的夹石的抗压强度有一些局限性。此外,还要注意合理规划布局骨料工厂,提高预见性;创新设计高端优质骨料,找准发力点。

  在谈到如何充分利用水泥企业的废石,创新设计高端优质砂石骨料生产线?进而为企业创造新的利润增长点的时候,谢教授表示优质骨料的性能指标一般除重点关注骨料的岩性外,同时关注骨料粒形、骨料的级配等技术指标。而在实际生产应用中,人们把关注的重点往往放在粒形而忽略了骨料的岩性和级配。正因为这样,在砂石骨料生产线设计建设时,在设备选型和加工工艺流程方面,往往没有加以考虑,以致后期要对骨料生产线进行改造才能够生产优质骨料。生产优质骨料看似设备、流程的选择会增加投资和运行成本,其实不然,优质骨料能够围绕以客户需求为中心,帮助混凝土生产施工企业降低成本,提升混凝土品质,这种客户的受益最终会传导到骨料生产企业,因此,可以这么说,砂石加工厂要把生产优质骨料作为创新设计的一条原则加以倡导与推广,旨在实现骨料制造业的优质高效和可持续发展。岩性、加工工艺流程、设备选型、设备制造厂家的实际业绩是影响获得高端优质骨料的主要因素。
