具体实施方式
实施例1
以下将结合附图所示的各实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本发明的技术解决方案为：一种高耐磨性高效碾磨系统。
需要说明的是，本实施方式中所提到的“第一”、“第二”并不代表结构或者功能上的绝对区分关系，而仅仅是为了描述的方便。
参图1，介绍本发明的高耐磨性高效碾磨系统一具体实施方式。在本实施方式中，该碾磨系统10包括磨辊11以及与其配合的磨盘12，磨辊11与磨盘12相对设置，磨辊11悬浮于磨盘12的上方，磨盘12可以由电机驱动绕其中心旋转，其中，磨辊11与磨盘12之间配合形成有物料空间13。
磨辊11上凸设第一耐磨层，第一耐磨层包括凸设的若干条凸棱和/或若干凸柱111，；磨盘12上凸设第二耐磨层，第二耐磨层包括凸设的若干条凸棱和/或若干凸柱121，该凸棱或凸柱111和121分别均匀地分布在第一耐磨层上和第二耐磨层上，其中，第一耐磨层与磨辊11共同构造有第一容料空间112，第二耐磨层与磨盘12共同构造有第二容料空间122，第一容料空间112和所述第二容料空间122至少构成物料空间13的部分。
当高耐磨性高效碾磨系统在工作过程中，物料14从喂料口(图中未示出)散落到旋转磨盘12的中央，形成物料料层，在离心力与甩出的过程中被悬浮于磨盘12上方的磨辊11碾压粉碎，在此过程中，物料空间13中充满物料14，其中，部分细小的物料141被填充在第一容料空间112和第二容料空间122中，大颗粒的物料142被磨辊11和磨盘12碾压时因为磨辊11和磨盘12上凸棱111和121的形状，增大了碾入角a，使大颗粒物料142在碾压过程中有稳定的保持力，增大扒料力度，不容易打滑，提高碾磨效率。
具体地，部分细小的物料141被填充在第一容料空间112和第二容料空间122中，相当于在磨辊11和磨盘12之间形成有效料层，使得碾压过程中，物料14先接触细小的物料141和凸棱111和/或121，这对磨辊11和磨盘12是个有效的保护，减少对磨辊11和磨盘12的磨损。下面的图表为同一台年产30万吨的矿渣立磨在传统工艺和增加了耐磨层的状态下的生产情况对比：
Figure PCTCN2014093098-appb-000001
Figure PCTCN2014093098-appb-000002
从图中可以清楚的看到，增加了耐磨层的碾磨系统的磨辊和磨盘的损耗明显低于传统工艺下的损耗，可以为企业降低生产成本，增加磨辊和磨盘的使用寿命。
在此值得一提的是，磨辊11和磨盘12上的凸棱或凸柱111、121可以呈现多种形状，例如：交错呈网格状设置(参图2)；彼此平行设置(参图3)；呈波浪形设置(参图4)；呈人字形设置(参图5)；呈错位设置(间断一字型)(参图6)；呈点型设置(参图7)。无论哪种形状的凸棱或凸柱，其所起的作用都是保护磨辊11和磨盘12，防止磨辊11和磨盘12过早磨损。磨辊11和磨盘12上的凸棱或凸柱的形状可以设置为相同，也可以设置为不同，在本实施方式中，其上磨辊11和磨盘12上的第一耐磨层和第二耐磨层的形状优选地设置为不同，以提供更好的扒料力度，以及对物料更好的碾磨粉碎效果。
第一耐磨层和第二耐磨层可以是与磨辊11和磨盘12一体成型，也可以是采用电弧焊接或铸造或镶嵌或喷焊或机械加工形成在磨辊11和磨盘12。
本发明通过上述实施方式，具有以下有益效果：通过在磨辊和磨盘之间设置对于物料有稳定保持力的物料空间，可以有效地避免磨辊和磨盘的过快磨损，并且，物料空间可以增大磨辊碾入角，增大扒料力度，增大摩擦力，提高磨辊和磨盘的耐磨性，提高立磨的总产量。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
