背景技术：
目前成熟的磨矿技术是干式破碎+湿式磨矿，所有设备均是平放在地平面上，占地面积非常大，设备的土建基础也非常复杂，建设难度大；另一方面，同时需要大量用水进行磨矿，所以水消耗量大，同时尾排水造成水污染。现有技术的磨矿是通过钢球砸向矿物来破碎的，在钢球砸向物料的同时有大部分钢球并未砸中矿物，而是砸中钢球，所以现有技术的磨矿过程中约有50％的无用功，增加了功耗。
中国专利CN102489373B中公开了一种铁矿石加工选矿工艺，在该专利文献中提到了干式磨矿的工艺步骤：即1.提升机将破碎后粒度＜30mm的粗矿提升到高处的第二皮带输送机上，由第二皮带输送机喂入无动力风选机中；2.无动力风选机将粗矿石和细矿粉分离开，粒度＞1.5mm的粗矿石在自重的作用下进入下方的稳流仓中，粒度≤1.5mm的细矿粉在风的作用下被选出，并通过风力送入动力风选机中。本领域技术人员根据此专利文献设计出如图1、图2和图3所示的磨矿系统。但是，根据该专利文献做出的生产系统中仍普遍存在以下问题：
1、占地面积大。按小时处理量70吨的生产规模计算，图1、图2和图3所需占地面积约为1200平方米。
2.物料的输送受皮带机的爬升角的限制，若要实现将物料输送到一下台磁选机的入料口，则皮带机的最短长度应不小于L(计算公式：L＝h/tan(α)，其中：h为磁选机入料口的最低高度，α为皮带机的最大倾斜角)；同时当磁选机的数量越多，所需要的皮带机就越多，皮带机的安装地盘就越大，皮带的耗费就越大。
3.按小时处理量70吨的生产线计算，图1、图2、图3需要至少5台皮带机，皮带的耗费按处理80万吨总量计算，则需要10套皮带。按小时处理量70吨的生产规模计算，每小时会耗费23度电，会导致巨大的能耗。
4.现有技术的磨矿所得到的细粉，细粉中的金属矿物颗粒与脉石矿物颗粒的粉碎是相同的，当磨矿细度太粗时，则会降低精矿品位，因金属矿物颗粒未得到 完全解离，因此选出的精矿中夹带脉石，品位低；当磨矿细度太细时，则会增加磁选难度而选不出金属矿物颗粒。

有益效果
1.本发明的磨矿系统充分利用空间资源，极大的优化了系统的整体构造，不仅物料流动更加顺畅，而且节省了占地面积，按小时处理量70吨的生产规模进行计算，本系统占地只需400～350平方米甚至更少，与现有技术相比减少占地71％以上，而且本系统物料传输距离只有150～70米，与现有技术相比减少传输距离62～80％。同时整个系统不用水，节约了设备成本和水资源。
2.本发明磨矿效果好，一方面，经本系统处理后的矿料品质好，经磨矿系统处理后，矿粉的粒径在-200目55％～95％范围内可调控，产品粒度的调节范围宽，可 根据用户的实际生产需求进行选择。另一方面，经磨矿系统处理的矿石，配合料床形式，矿物颗粒按结晶体形成面自然解离磨碎的，即使那些未完全解离的矿物颗粒在其内部也存在许多微裂纹，为再次的磨碎更加容易，因此可提高处理量以及效率，按小时处理量70吨的生产线比较。现有技术的磨矿能力为70t/h，而相同规模下本系统的处理能力可达到84～105t/h，磨矿的产量可提高20～50％、效率提高20～30％。
3.本发明按小时处理量70吨的生产规模进行比较，需18～13度电，节电20～43％。
4.本系统的整体构造、装置间的位置和连接方式等，极大的减少了矿选过程中对空气造成的污染。空气排放的粉尘含量小于20mg/Nm3，优于国家标准规定的粉尘排放要求不大于30mg/Nm3的环保要求，无大气污染。
5.本系统磨矿、分级、筛分过程物料流动顺畅，不会出现物料淤积堵塞现象，不仅保证了产品的品质，同时提高设备的使用寿命，降低维修成本。
6.在本磨矿系统处理粗矿的过程中，所做的功得到充分利用。矿石以料床形式在压力的作用下进行挤压粉磨磨碎的，矿物颗粒之间相互挤压而破碎，外力施加压力所做的功得到全部利用。
7.经本磨矿系统处理后的细粉更适合于后续的磁选，矿物颗粒是按结晶体形成面自然解离磨碎的，金属元素与脉石矿物得到完全解离，为后续的磁选过程中更容易选出金属矿物颗粒。
8.本发明的矿选系统降低了投资成本，现有的矿选系统需要建立尾矿坝来处理磁选后产生的废水和废料，而本矿选系统只需收尘系统将其产生的干式粉尘进行收集并回填就能解决废料的问题。按日处理量1700吨的生产规模进行比较，现有技术在尾矿坝上的投入成本约陆仟万元，而后期的维护成本也非常高，每年需要约贰仟伍佰万元的费用；而本发明不需要建尾矿坝，只需将收集的尾粉进行回填，因此在尾矿的处理上只需要约壹佰万元即可，可节约支出染、捌仟万元。
9.本发明的矿选系统综合能耗低，本矿选系统在工作过程中的能耗低于中华人民共和国黑色冶金行业标准——《矿山企业采矿生产能耗定额标准第2部分：铁矿石选矿YB/T4417.2-2014》中规定的磁选流程、浮选流程的单位原矿选矿综合能耗的一级标准30％。
