现有技术的雷蒙磨在工作时，将需要粉碎的物料从机罩壳侧面的进料斗加入机内，依靠悬挂在主机梅花架上的磨辊装置，绕着垂直轴线公转，同时本身自转，由于旋转时离心力的作用，磨辊向外摆动，紧压于磨环，使铲刀铲起物料送到磨辊与磨环之间，因磨辊的滚动碾压而达到粉碎物料的目的。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
在磨辊向外摆动，紧压于磨环时，磨辊会与磨环接触，导致磨辊与磨环过早地磨损，使得雷蒙磨的整个工作周期相对较短，而且需要经常维护，不利于高效率研磨细粉料。

请再次参考图1，多个压紧轴套4的靠近磨辊主轴2侧42的上端还分别设置有一向上延伸的压紧耳片43，压紧耳片43与压紧轴套4优选为一体式结构，但并不以此为限。
请再次参考图1，多个限位支座5与多个压紧耳片43对应设置于压紧支座3上，并位于多个压紧轴套4的远离磨辊主轴2侧，各个限位支座5优选为单耳式结构，以减轻具有磨辊加压限位装置的雷蒙磨1整体重量，同时还可以保证其具有足够的强度，但并不以此为限。请参考图3，其示出了本发明一实施例的限位支座5与压紧支座3连接的示意图。本实施例公开的多个限位支座5是通过至少两根连接螺栓13以及第一螺母组件14固定于压紧支座3上，以确保各个限位支座5与压紧支座3具有足够的连接刚度和强度,但并不以此为限。本实施例进一步公开的多个限位支座5是固定于U型连接支撑11上，但并不以此为限。
请再次参考图1，多个带螺纹拉杆6对应设置于多个限位支座5与多个压紧耳片43之间，并与多个限位支座5及多个压紧耳片43对应连接，本实施例公开连接方式是，多个带螺纹拉杆6的一端穿过与其对应的多个限位支座5与多个限位圈17对应连接，并通过多个限位圈17卡紧于多个限位支座5，多个带螺纹拉杆6的另一端穿过与其对应的多个压紧耳片43与多个第二螺母组件18连接，但并不以此为限。
请再次参考图1，多个压紧轴套4的靠近磨辊主轴2侧通过多个压紧耳片43、多个带螺纹拉杆6及多个限位支座5与压紧支座3连接，多个压紧轴套4通过压紧支座3带动而以磨辊主轴2为轴心转动。
请再次参考图1，多个弹簧7设置于多个带螺纹拉杆6上，并位于限位支座5与压紧耳片43之间，多个弹簧7呈复位状态，并且当 多个压紧轴套4以磨辊主轴2为轴心转动时，多个弹簧7呈拉伸状态，通过多个弹簧7拉伸多个压紧轴套4，以保证与其连接的磨辊轴8在磨环101内保持一定的距离，最终确保固定在磨辊轴8底部的磨辊9与磨环101之间具有一个不接触的间隙(第二间隙),这个不接触的间隙始终大于零，进而保证磨辊9与磨环101不接触地研磨磨辊9和磨环101之间的物料，最终保证磨辊9与磨环101不接触磨损，提高这两个关键以及重部件的使用寿命，最终提高了具有磨辊加压限位装置的雷蒙磨1的使用寿命。
多个磨辊轴8的顶部与多个压紧轴套4对应连接，多个磨辊轴8通过多个压紧轴套4与压紧支座3连接，多个磨辊轴8通过多个压紧轴套4带动而以磨辊主轴2为轴心转动。
在一优选实施例中，请再次参考图1，多个压紧轴套4的上端还对应设置有多个压紧盖15，多个压紧盖15的设置方式可以是通过螺栓对应安装于多个压紧轴套4的上端，但并不以此为限。多个压紧盖15用于密封多个压紧轴套4的上端，但并不以此为限。
多个磨辊9与多个磨辊轴8的底部对应固定连接，多个磨辊9通过多个磨辊轴8带动而以磨辊主轴2为轴心转动。请再次参考图1，本实施例公开的多个压紧轴套4的下端还依次设有倒扣喇叭形连接部45和收紧轴套46，以保证整个压紧轴套4和磨辊轴8的上下位置平衡，同时可以增强磨辊轴8的旋转稳定性，收紧轴套46压紧在磨仓10上，以密封磨辊9。
请再次参考图1，磨仓10具有多个与多个磨辊9对应的磨环101， 多个磨辊9对应设置于磨环101内，并与其对应的磨环101之间具有第一间隙。
当多个磨辊9以磨辊主轴2为轴心转动时，多个弹簧7呈拉伸状态，并对多个磨辊9产生一拉力，通过该拉力拉紧多个磨辊9，使多个磨辊9与磨环101之间具有第二间隙，也即磨辊9与磨环101之间具有一个不接触的间隙，第二间隙小于第一间隙。
在一优选实施例中，请再次参考图2，多个U型连接支撑11的数量为四个，四个U型连接支撑11沿着磨辊主轴2的周向呈间隔均匀设置于压紧支座3的端部，同时，与四个U型连接支撑11对应的还设置有四个压紧轴套4、四个磨辊轴8及四个磨辊9，即一共设置有四根磨辊9和四个磨环101，使整个具有磨辊加压限位装置的雷蒙磨1的研磨效率最高，且研磨稳定性最强。
本实施例的具有磨辊加压限位装置的雷蒙磨1在研磨物料时，驱动机构驱动磨辊主轴2转动，通过磨辊主轴2依次带动压紧支座3、多个压紧轴套4、多个磨辊轴8及多个磨辊9以磨辊主轴2为轴心转动，由于离心力的作用，使多个磨辊9向外(磨环101)靠近，第一间隙减小，多个弹簧7呈拉伸状态，起到了很好的加压和缓冲作用，拉伸多个压紧轴套4，进而拉伸多个磨辊轴8及多个磨辊9，进而对多个磨辊9起到加压和缓冲作用，减小具有磨辊加压限位装置的雷蒙磨1的振动。
同时，多个弹簧7还使多个磨辊9与磨环101之间具有第二间隙，也即多个磨辊9与磨环101之间具有一个不接触的间隙，防止多个磨 辊9与磨环101接触磨损，提高这两个关键以及重部件的使用寿命，最终提高了具有磨辊加压限位装置的雷蒙磨1的使用寿命。
上述说明示出并描述了本发明的若干优选实施方式，但如前所述，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施方式的排除，而可用于各种其他组合、修改和环境，并能够在本文所述发明构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
