Description

适于高水分物料的组合式水泥粉磨系统及方法 技术领域
本发明涉及一种物料粉磨系统，尤其涉及一种集烘干、选粉与粉磨功能于一体的适于高水分物料的组合式水泥粉磨系统及方法。
背景技术
在建材业尤其是水泥粉磨领域，球磨机尽管粉磨效率低，但磨制的水泥性能是其它粉磨设备难以替代的，所以目前水泥粉磨系统多数还是采用球磨机或以球磨机为主来制备水泥。为了提高球磨机系统产量，降低系统粉磨电耗，往往采取降低入球磨机物料粒度的方法，在球磨机前加高效的研磨装置，目前以加辊压机、外循环立磨等高效料床粉磨装备为主，大大提高了系统产量、降低了系统电耗。但随着资源的日益紧缺，磨制水泥的缓凝剂与混合材逐步被工业废渣所取代，进而脱硫石膏、冶金废渣等工业废渣获得大量应用。然而目前很多工业废渣以湿排为主，含水率较大，其作为水泥原料后水泥原料的综合水分随之增加，原料较大的含水率会带来以下问题：
(1)料床粉磨预粉磨装备不能适应高水分物料。
(2)高水分物料进入球磨机，造成球磨机糊球、糊磨、堵篦缝等问题，使得球磨机不能正常运行。
(3)当高水分缓凝剂与混合材参与配料时，在配料皮带上、斗提机里与熟料混合，会导致部分粉状熟料提前水化，降低水泥强度，增加熟料配比，增加生产成本。
(4)当熟料温度较高时，高水分物料与熟料混合，会导致水汽在入磨前的输送过程中蒸发出来，与扬尘一起进入收尘器，造成收尘器糊袋。
解决以上高水分带来的问题，往往采取烘干的措施，将这些高水分物料单独烘干后再进入原料库或原料仓，此措施尽管较好地降低了原料水分，使得问题解决，但需要消耗的热耗较高。在粉磨系统的选粉装置中同步实现烘干与粉磨，不但能耗较低，也能起到较好的烘干效果，但是若用一条配料皮带机直接将配好的所有物料均喂入选粉装置，实现物料先烘干选粉再粉磨是个不错的方法，但会大幅增大选粉装置的规格，也增大了选粉风机的规格，进而增加了系统粉磨电耗。
再者，工业废渣往往颗粒较细，直接喂入料床粉磨料床粉磨装置，会导致料床粉磨设备的稳定性变差。
发明内容
为了克服现有技术的不足，本发明提供了一种适于高水分物料的组合式水泥粉磨系统及方法，其根据物料的性能，将物料进行干湿分类、粗细分类来处理，对于细粉物料与高水分物料采取先烘干选粉再粉磨的方式，对于水泥熟料与块状低水分物料采取先粉磨再选粉的方式，简单有效的解决了以上难题。

参照图3，本发明优选实施例3提供一种适于高水分物料的组合式水泥粉磨系统，与实施例1所不同的是，所述选粉装置由V型选粉机4-1与精细选粉机4-2串联组成，其中所述V型选粉机4-1的粗料出料口与料床粉磨装置2的喂料口相连，料床粉磨装置2的出料口通过所述循环斗提机3与V型选粉机4-1的进料口相连，第二皮带机5的出料端同样与V型选粉机4-1的进料口相连；所述热风装置10与V型选粉机4-1的进风口相连，V型选粉机4-1的细料出料口与精细选粉机4-2的进料口相连，精细选粉机4-2的细料出料口与所述除尘器的进料口相连。
系统风路走向：热风依次经过热风装置10、V型选粉机4-1、精细选粉机4-2、收尘器6、风机7，最后由风机7的烟囱排向大气；料路设备：料床粉磨装置2、选粉装置4、球磨机9组成联合粉磨系统，物料A从料床粉磨装置2进入粉磨系统，物料B从V型选粉机4-1进入粉磨系统，精细选粉机4-2选出的细粉通过斜槽8全部喂入球磨机9，即可实现联合粉磨系统功能。
实施例4
参照图4，本发明优选实施例4提供一种适于高水分物料的组合式水泥粉磨系统，与实施例3所不同的是，所述精细选粉机4-2为三分离选粉机，其细料出料口与所述除尘器6的进料口相连，中粗料出料口与球磨机9的进料口相连，粗料出料口与料床粉磨装置2的进料 口相连；除尘器6的出料口通过斜槽8与球磨机9的出料口相连。即本系统中料床粉磨装置2、选粉装置、球磨机9组成半终粉磨系统。
需要说的是，无论是实施例3还是实施例4，物料的水分烘干与选粉均在V型选粉机4-1、精细选粉机4-2里依次进行。
本专利应用于水泥粉磨领域，也可应用于其它粉体物料的粉磨制备。
实施例5
本实施例提供一种基于实施例1所述组合式水泥粉磨系统的高水分物料粉磨方法，其特征在于，将熟料与块状低水分物料经过第一皮带机输送至料床粉磨装置进行粉磨，研磨后经过循环斗提机喂入选粉装置；细颗粒物料以及水分较大的物料经过第二皮带机直接送至选粉装置；选粉装置中细粉被选出并经过收尘器收集后喂入球磨机，粗粉返回料床粉磨装置进行循环粉磨。
以上所述的仅为本发明的优选实施例，所应理解的是，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想，并不用于限定本发明的保护范围，凡在本发明的思想和原则之内所做的任何修改、等同替换等等，均应包含在本发明的保护范围之内。
