一种球磨机衬板组件及其安装方法 技术领域
本发明涉及的是一种球磨机衬板，尤其是一种球磨机衬板组件及其安装方法。
背景技术
球磨机是矿山、水泥、电力、化工等行业使用的主体粉磨设备，到目前为止，球磨机衬板仍以金属为主，部分二、三段工况下采用橡胶，据统计全国每年消耗的金属衬板大概在60万吨左右，其中金属主要原料是铁，铁是人类拥有的有限资源，尤其是在中国，铁矿贫瘠，开采成本高，环境污染严重；金属衬板的主要问题是重量大、磨损严重、金属消耗大、运营成本高、球磨机运行能耗高、工作环境恶劣、维修工作量大；金属衬板生产能耗高，在生产过程中有废砂废气等环境污染，在水泥行业中，金属衬板磨损带来的金属夹杂物会降低水泥品质，在食品和医药行业中，金属衬板会带来重金属污染，危害极大；在矿山行业中，金属衬板的使用和维修是影响产量和生产成本的主要因素之一；少数工况下使用的橡胶衬板虽然降低了部分成本，但其使用寿命低于金属衬板且由于橡胶的弹性造成球磨机产量下降10％；因此亟需研制一种球磨机衬板组件及其安装方法，以解决上述存在的问题。
发明内容
本发明提出了一种球磨机衬板组件及其安装方法,克服了现有技术中的不足和问题，提高了使用寿命、研磨效率、减少了能耗和成本。
申请人提出球磨机衬板组件涉及的球磨机是研磨设备，不是破碎设备，少破多磨理论是提高生产效率、减少磨损的根本解决方案。随着预粉碎技术的应用，破碎工段放在磨前，入料粒度降低，球磨机逐渐作为专业研磨设备工作，而传统理论中磨球级配及大直径用于破碎的磨球和球磨机破碎仓段为提高生产效率、降低磨损带来了非常大的负面影响。申请人经过研究发现传统球磨机级配中的大尺寸磨球(直径大于40mm)对有磨前预粉碎技术的球磨机入料颗粒(直径在1mm或以下)无法产生有效的研磨作用，但对衬板造成了严重的破坏作用；由此，申请人提出了一种球磨机衬板组件，因为有之前的预粉碎工艺，且磨球尺寸设置为40mm以下，因此为陶瓷衬板的使用提供了可能，本发明可以极大的提高磨机衬板使用寿命，降低磨机衬板更换维修量，提高企业生产率，有效降低球磨机运行能耗；在水泥行业，陶瓷材料的应用可以避免金属衬板带来的金属污染，有助于提高水泥的品质。
本发明的技术问题是通过下面的技术方案解决的：

进一步设计在于：还包含安装模块，所述耐磨衬板呈与球磨机筒体内壁相适应的圆弧形，与筒体内壁相贴合的侧面为光滑表面或镂空表面，其另一侧面为作业面，作业面整体呈沿筒体圆周向分布的波浪形并且沿筒体轴向均匀设置有若干个用于导向研磨球体运动的沟槽；多个自固衬板在球磨机筒体圆周向上通体均匀间隔设置，两相邻自固衬板之间填充设置有一组耐磨衬板、安装模块，自固衬板和耐磨衬板沿筒体圆周向的同向端面分别设置有两个凸台形成凸台端，两者与凸台端相对的侧面均为平面；安装模块一侧与耐磨衬板的平面端相连接，自固衬板与耐磨衬板有凸台的一端相连接，自固衬板的凸台端与安装模块的另一侧面相抵；耐磨衬板、自固衬板通过各自的凸台端与各自相邻的自固衬板、安装模块形成两点挤压接触连接，使得衬板之间稳定配合；各自固衬板与安装模块之间设有过盈插接有硬质的垫片，使得耐磨衬板、自固衬板、安装模块之间充分挤压接触，并且安装模块避免了垫片对自固衬板过盈挤压造成的破坏。
进一步改进在于：自固衬板上设有螺孔。
进一步改进在于：凸台沿球磨机筒体轴向方向两侧有斜角或圆弧。
进一步改进在于：使用安装模块，由低碳合金钢或钢板制成
进一步改进在于：自延展性材料为低碳合金钢或者碳钢。
一种球磨机衬板组件安装方法，包括如下步骤：
首先用自固衬板沿球磨机筒体圆周向将筒体分成适当几个区域，利用球磨机筒体已有螺孔将自固衬板固定。
将耐磨衬板圆周向放入球磨机筒体自固衬板划分的区域内；
在自固衬板凸台上方放入安装模块，使其与自固衬板凸台端相接触并与耐磨衬板无凸台端接触；
用楔铁插入自固衬板与安装模块之间的空隙，并用锤击打楔铁使两侧衬板沿圆周向紧固，并将垫片嵌入自固衬板与安装模块之间的空隙中，以使整个区域内衬板之间实现紧密配合，然后抽出楔铁。
本发明使用陶瓷材料取代金属，适当调整球磨机中磨球最大尺寸的工况下，陶瓷衬板可以可靠稳定地应用在球磨机上。陶瓷衬板使用寿命可达金属衬板的4-6倍，极大地提高了企业生产效率，降低生产成本，陶瓷密度只有金属的38.5％，整套衬板重量只有金属衬板的40％左右， 陶瓷衬板的应用可降低球磨机运行能耗；在水泥行业，陶瓷材料的应用可以避免金属衬板带来的金属污染，有助于提高水泥的品质。陶瓷衬板的使用可以有效的改善工人的工作环境，显著降低噪音。陶瓷衬板生产过程中可以消除传统金属衬板生产造成的废砂、废气等环境污染，大大降低生产能耗，同时极大的避免了大量金属和昂贵合金元素的消耗，陶瓷材料的应用将极大的降低国家环境及能源成本；本发明在极大提高企业生产效率的同时将带来巨大的社会效益，节约资源。
本发明使用球磨机衬板组件安装方法，可以有效的使衬板之间紧密配合，并避免压紧过程中的陶瓷衬板断裂。
本发明采用无螺栓设计及组合的安装形式，避免螺孔成为衬板应力集中点，造成陶瓷衬板出现裂纹或衬板开裂情形，在解决衬板应用高硬度低韧性耐磨材料难题的同时，也解决了传统有螺栓衬板断螺栓、漏粉漏料、停工、污染环境和繁重复杂的安装方式等问题，大幅度降低传统有螺栓衬板维修量，进一步提高了企业的生产效率和工作环境。
