离心选矿机：
离心机选型应注意以下几个方面  1、防腐性能：  离心机所分离的物料一般都具有一定的腐蚀性，与物料接触部分的材质，必须能够达到耐腐蚀的要求，一保证安全使用。结构件材料、密封垫材质、表面处理措施，以及滤布的材质均应在选型时确定。可在选型时将物料的性质（化学性质、分离时温度等）告知我公司，以便我公司能够根据所分离介质的饿特性提出离心机材质选用的建议，并在订单中注明，以确保离心机的防腐要求。 2、防爆性能：离心机所处理的物料中如含有有机溶剂等易燃易爆的物质，则离心机应具有防爆性能。防爆性能视工艺的防爆要求等级确定。以前涉及到的防爆场合，只是提出配制防爆电机，近两年，对于所处理的物料中含有溶媒等有机溶剂的场合，大多都提出痰气保护的要求。实际上，离心机要实现真正意义上的防爆，可在机械、电附件配制方面采取多方面措施，如采用防爆电机，防爆照明灯，防静电皮带，防撞措施，安全连锁装置、氮气保护装置，非接触式能耗制动，静电接地，防爆自动控制等等。因此客户在订货时必须说明所需分离介质的特性、防爆要求和等级。 3、分离性能：  分离性能是一个最基本的功能，包括分离的效果、洗涤效果、处理能力、自动化程度等，因物料性质的差异，包括物料的黏度、密度、料浆的固液比等因素，很难精确的确定最终分离的效果，一般来说，分离因素是影响离心机分离效果的重要因素。分离因素与转鼓的转速和转鼓直径有关，与转鼓的角速度平方成正比关系。 洗涤是指对滤饼的洗涤，对于有的物料，滤饼还需经过洗涤液进行洗涤，有的甚至要经过几次洗涤才能达到要求，这就需要配制洗涤管，洗涤的效果、洗涤的时间与洗涤管孔径、布置位置、结构形式有很大关系。离心机的处理能力与物料的物理化学性质和分离要求有关，一般以一小时的循环次数及单次运行的滤饼质量来估算。 五、离心机的安装要求：1、设备安装前后必须注意保管，注意电机、电控装置、液压系统的防潮及所有零部件的防腐，并注意对机器外表面的保护。 2、安装必须注意安全，以免机器受到碰撞而损坏。 3、与离心机相邻安装的设备及其它装置与离心机之间应有足够的使用和维修空间，在离心机主机的四周要有不小于1米的人行道。离心机主机的上方必须要有2米的装拆维修空间。在对电气控制柜、液压系统进行安装定位时，也必须预留一定的拆装维修空间，以免机器受到损坏或出现异常情况时维修。 4、电气柜应放置在干燥、通风和无腐蚀的环境，并通风良好。操作台应安装在主机旁，以便观察与操作。 5、离心机安装必须水平，基准面为机座平台上平面，浇制基础时，。基础重量约为机器重量的3倍，基础除受机器的静载荷外，还承受机器运转时的动载荷（动载荷约为机器重量的0.5倍）。 6、机器一般为整机安装，不得拆卸，如必须拆卸维修，需由制造厂技术人员进行验收，验收合格后方可投入使用。 7、由于离心机在运转时产生轻微振动，因此与离心机连接的管道（排气管、出水管等）必须使用软连接，连接处应保证密封或绝缘，应使用三相电源，以防止触电事故的发生。 8、外接出液管的直径不得小于离心机出液管口直径，不得有堵塞，且应低于出液口的高度，以便出液流畅。 六、滤布的选用； 1、离心机采用滤布作为过滤介质时，转鼓中装有金属衬网，滤布铺设在衬网上并作固定。由于滤布较软，强度较低，衬网的网孔应小一些，以便有效地支撑滤布、通畅地排出滤液滤布要求有足够的强度、适宜的孔隙大小和孔隙率，对所处理的物料有耐腐蚀性，并有一定的耐磨性。滤布有三种织法，平纹、斜纹和缎纹，平纹的织法最紧密，斜纹次之，缎纹则较疏，孔隙率依次增加。滤布选择应通过试验确定，各种滤布的特性如下、棉布机械强度、耐磨性和耐温性良好，孔隙小，不受冷稀酸的影响。 B、锦纶布抗张强度高，耐磨性特别好，表面光滑，卸渣方便，能抗大多数碱类和任何浓度的有机酸。C、涤纶布强度及耐磨性良好，耐酸性特强，耐碱性良好。D、聚丙烯布耐磨性和耐温性良好，对无机酸有良好的抗蚀性，对弱碱和室温下的强碱有较强的抗蚀性，在浓度低于80%的硫酸不被溶解E、聚乙烯布室温下对于碱和无机酸具有耐蚀性，价格低，但纤维较弱，强度较差。 F、聚氯乙烯布对于各种浓度的强酸和较高温度下的浓碱有良好的饿抗蚀性，表面光滑，便于卸渣。2、滤布过滤目数（型号）按所分离物料直径确定，一般在选择滤布目数时应稍大于所要截留的颗粒直径，在过滤的初级阶段有少量的小颗粒穿滤，当所截留的较大颗粒搭桥形成滤饼层后，就可以消除穿滤现象，有助于提高过滤效率。3、滤布建议采用单丝双层复合滤布，过滤面经砑光处理，以减小滤布堵塞的可能和提高滤布的再生性能。 七、离心机的安全使用要求； 1、选型要正确。2、按规定的范围使用离心机，不可以将一般用途的离心机用于易燃易爆场合和具有腐蚀性的场合、按规定的操作规程运行，不得非正常制动和超负荷运转、超速运转。 4、应及时排除故障，不得运行带故障的离心机，及时报废失效的离心机。 5、按产品使用说明书中的要求安装、使用、维护离心机，不得自行修改离心机的零部件，不得自行提高离心机的转速。6、制定离心机安装、使用和维护等相应的规章制度并严格执行，以达到安全使用的目的。

Centrifugal concentrator:
Selection centrifuge should note the following aspects 1, corrosion resistance: centrifuge separated materials generally have some corrosion, material contact parts of the material and must be able to achieve the requirements of corrosion resistance, a guaranteed safe to use. Structure material, gasket material, surface treatment measures, as well as cloth material should be determined at the time of selection. Available in the selection of the nature of the material (chemical properties, the separation temperature, etc.) to inform my company, so I can make recommendations based on material selection centrifuge hungry media separation characteristics, and indicated in order to ensure centrifuge corrosion requirements. 2, explosion-proof performance: Material processed in centrifuges as containing organic solvents and other flammable substances, the centrifuge should be explosion-proof. Explosion-proof performance requirements depending on the process of determining the grade. Previously involved in hazardous areas, only raised the preparation of explosion-proof motor, the last two years, for the material being processed in a solvent containing an organic solvent such occasions, most have put phlegm protection. In fact, the centrifuge to achieve a real sense of proof, a variety of measures can be taken in the mechanical, electrical accessories preparation areas, such as the use of explosion-proof motor, explosion-proof lighting, anti-static belt, crash measures, safety interlock device, nitrogen protection device Non-contact dynamic braking, static grounding, explosion-proof automatic control and so on. Therefore, customers must specify when ordering the required characteristics of the separation medium, explosion-proof requirements and grade. 3, the separation performance: the separation performance is a basic function, including the effect of separation, washing effect, processing power, automation, etc., because of differences in material properties, including viscosity material, density, slurry of solid-liquid ratio and other factors it is difficult to accurately determine the ultimate effect of separation, in general, the separation factor is an important factor affecting the centrifuge separation effect. Separation factor and the rotational speed of the drum and the drum diameter related to the relationship between the square of the angular velocity of the drum. Washing refers to washing cake, for some materials, the cake needs to go through the washing liquid washing, some even after several washing to meet the requirements, which requires the preparation effect washing pipe, washing, washing time washing tube aperture arranged location, structure of a great relationship. Centrifuge and the material handling capacity of the physical-chemical properties and requirements for separation, generally one hour cycles and cake quality in a single run to estimate. V. centrifuge installation requirements: 1, before and after the installation must take good care, pay attention to the motor, corrosion and moisture electronically controlled, hydraulic system and all components, and pay attention to the protection of the outer surface of the machine. 2, the installation must pay attention to safety, to prevent the machine from being damaged by the collision. 3, should be installed between adjacent centrifuge equipment and other devices with the use and maintenance of the centrifuge enough space around the centrifuge host should have not less than one meter of the sidewalk. Top centrifuge host must have two meters of assembly and disassembly repair space. When the electrical control cabinet, the hydraulic system installation location, you must also set aside some space for disassembly and maintenance, in order to avoid damage to the machine or repair abnormal situation. 4, electrical cabinets should be placed in a dry, ventilated and non-corrosive environment and good ventilation. Console should be installed next to the host, in order to observe the operation. 5, centrifuge installation must be level, datum plane as the base platform, when casting basis. The basis weight of about 3 times the weight of the machine, the machine base being subject to static load, but also to withstand dynamic loads during operation of the machine (dynamic load of about 0.5 times the weight of the machine). 6, the machine is generally the whole installation, do not remove, such as maintenance must be removed, the need for acceptance by factory technicians put into use only after acceptance. 7 centrifuges in operation due to a slight vibration, so the pipe is connected with the centrifuge (exhaust pipe, outlet pipe, etc.) must use the soft connection, the connection should ensure sealing or insulation, use a three-phase power supply to prevent electrical shock accidents. 8, the external diameter of the tube is not less than the diameter of the nozzle centrifuge the solution, not a blockage, and should be less than the height of the liquid outlet so that the fluid flow. Six cloth selection; a centrifuge using cloth as the filter media, drum lined with metal mesh, cloth laid on the Internet and make fixed lining. Since the filter cloth softer, lower strength, mesh lining sites should be smaller, in order to effectively support the filter cloth, the cloth smoothly discharged filtrate requires sufficient strength, a suitable pore size and porosity of the processed materials are resistant to corrosion and has some wear. There are three weave cloth, the most closely plain, twill and satin, plain weave, twill, followed by a satin are more sparse, followed by increased porosity. Choose the filter cloth determined by experiment, characteristics of various filter cloth follows, cotton mechanical strength, excellent abrasion resistance and temperature resistance, low porosity, cold dilute acid from the impact. B, high tensile strength nylon cloth, wear resistance particularly good, smooth surface, easy to remove slag, resistant to most alkalis and acids at any concentration. C, polyester fabric strength and good wear resistance, particularly strong acid, alkali resistance is good. D, polypropylene fabric abrasion resistance and good heat resistance, inorganic acids have good corrosion resistance of alkali weak base and strong room temperature corrosion resistance, at concentrations of less than 80% of the sulfuric acid is not is dissolved E, at room temperature for polyethylene cloth having a base and an inorganic acid corrosion resistance, low price, but the fibers is weak, poor strength. F, polyvinyl chloride cloth for various concentrations of strong acids and concentrated alkali at higher temperatures there is good hungry corrosion resistance, surface smoothness, ease of dumping slag. 2, cloth filter mesh (models) diameter determined by the separation of materials, generally choose cloth mesh should be slightly larger than the diameter of the particles to be trapped in the filter of the primary stage of a small amount of small particles through the filter, when compared with the retention After the formation of large particles bypass cake layer, the phenomenon can be eliminated through filtration, helps to improve the filtration efficiency. 3, monofilament filter cloth is recommended double-layer composite fabric, the filtering surface by calendering, to reduce the possibility of filter cloth clogging and improve the regeneration performance of the filter cloth. Seven, centrifuge safety requirements use; 1, the selection should be correct. 2, according to the scope of the provisions of the use of centrifuges, can not be used for general purpose centrifuge explosive situations and corrosive applications, follow the rules and regulations of operation, not a non-normal braking and overload, speeding operation. 4, timely troubleshooting, not run the centrifuge with failure, failure promptly scrapped centrifuge. 5, according to product specification requirements for the installation, use and maintenance of centrifuges, centrifuge parts may not modify themselves, not on their own to improve the speed of the centrifuge. 6, to develop appropriate rules and regulations, such as the centrifuge installation, use and maintenance and strictly enforced, in order to achieve the purpose of safe use.
