FLOWCHART OF R SERIES PENDULOUS ROLLER MILL PROCESS (RAYMOND MILL)
R系列摆式磨粉机工艺流程示意图（雷蒙机）
近年来随着非金属矿物质在超细粉体应用领域的广泛发展，下游企业对非金属矿产品的要求越来越高。特别是对产品细度有了更高的要求，这使得传统雷蒙磨显得力不从心，传统雷蒙磨存在的先天不足一直困扰着矿物加工企业和设备制造厂家。
In recent years, with the extensive development of nonmetallic minerals in the application field of ultrafine powders, downstream enterprises have increasingly high requirements for nonmetallic minerals. In particular, there are higher requirements for the fineness of products, which disenables the traditional raymond mill to meet these requirements. The inherent deficiencies of the traditional raymond mill have been perplexing mineral processing enterprises and equipment manufacturers
其中主要问题表现在： / The main problems are embodied in the following aspects:
●产品细度低，普通雷蒙磨细度一般在500目一下，这些设备只能占领较低端的粉体应用市场。
Low product fineness. The fineness of ordinary raymond mill is generally below 500 meshes. Such devices can only occupy the lower-end powder application market.
●机械故障率高、耗能大、噪音大、排放污染大。
High mechanical failure rate, high energy consumption, high noise and high pollution emitted.
●系统效率低产品的收集系统分离效果不理想，大量的细粉得不到有效的收集而在系统内重复循环造成动力浪费。
The separation effect of the collection system for products with low system efficiency is not ideal, and a large amount of fine powder is repeatedly circulated in the system rather than being effectively collected, resulting in power waste.
●主机风箱风道设计存在欠缺，进入研磨区物料中的较大颗粒和未来得及研磨碎的颗粒经常被跑进风箱聚集在蜗箱尾部，并不断向前延伸，使过风量逐渐减少，易造成塞车、不出粉或少出粉的现象，影响产量。
There are deficiencies in the air duct design of the main engine bellows. Larger particles and particles that have not been ground in time in the grinding area for materials often run into the bellows, gathering at the tail of the worm case and extending forward continuously, which gradually reduces the air volume, causes blocking with no powder or less powder easily, and affect the output.
经过我公司多年的设计、生产雷蒙磨机的经验，自主研发出的XR高细雷蒙磨粉机解决了这一难题，并获得了高新（号0052871.1）
For years of designing and producing raymond mill as a roller mill, XR high-fine raymond mill independently developed by our company has perfectly solved such problems and obtained a high-tech patent. (Patent No.: 0052871.1)
技术优势和特点/ TECHNICAL ADVANTAGES AND CHARACTERISTICS
对主轴和梅花架进行了有利于稳定运行的结构改造，使其运行平稳，中心轴区无摆动。将分析机由腔内拖式，改为腔外垂吊传动腔内旋转两隔离，增强了工作的稳定性、耐用性。在粉碎区部，使待研磨物料始终聚集在研磨粉碎区进行有效加工，提高了研磨效率。还对磨辊结构进行了更新，使磨辊轮和磨辊轴可以互补运转，在自转的同时也可以公转，使其功效和耐用性更强，并能在更大的研磨力和更高的运转速度下工作。在通风部分，将风箱和风道均有原水平底改为向中心倾斜，形成斗状，确保风箱、风道始终畅通无堵塞，从而使风量始终不会衰减，主机磨能够一直处于高值。分级机采用叶笼式分级系统，打打提高了产品细度。
采用新式雷蒙机可以对方解石、白云石、滑石、高岭土、重晶石、石英石、萤石等费经书矿物进行超细研磨。经实践检验，选用进料尺为25mm的方解石进行研磨，当细度调整到1250目（10um）时，产量可达到800-2000kg/h，比传统雷蒙磨机具有更高的性价比。
The spindle and star rack have been restructured in favor of stable operation, so that the operation will be more stable without swing in the central shaft area. The analytical engine is changed from towing in the cavity to hanging out of the cavity & rotation in the cavity, thus enhancing the stability and durability of the work. At that crush area, materials to be ground are always gathered in the grinding area for effective processing, to improve the grinding efficiency. The structure of grinding roller has also been updated, so that the grinding roller wheel and shaft can operate complementarily, and revolve while rotating, to improve their efficacy, durability and ability to work under greater grinding force and higher running speed. In the ventilation part, the original horizontal bottom of the bellows and air duct is changed to incline to the center and form a bucket shape to ensure that the bellows and air duct are always unblocked and free from blockage, so that the air volume will not reduce and the main mill can always operate at a high value. The classifier adopts a lantern-pattern classification system, which improves the fineness of the product.
The new raymond mill can be used for ultrafine grinding of calcite, dolomite, talc, kaolin, barite, quartz, fluorite and other nonmetallic minerals. The practice suggests that the selected calcite at a feeding size of 25mm for grinding. When the fineness is adjusted to 1,250 meshes (10um), the output can reach 800-2,000kg/h, which has higher cost performance than the traditional raymond mill.
