Pelletizin

2、g is an increasingly important process for fine grain ore concentrates. One condition for economical pelletization of wet or dry ground ore concentrates is a uniform, agglomeration-free mix with additives. This pre-treatment of ore concentrate is a vital step for downstream pelletizing in particular

3、 where bentonite and /or other additives are intermixed, and where liquid components are added.礦石為地面的精礦，作為選礦用，在采礦過程中產(chǎn)生的礦粉塵必須在熔煉之前壓縮。粒化是精鐵礦的重要過程。濕或者干的地面精礦經(jīng)濟(jì)?；囊粋€(gè)條件是均一，有添加劑的無團(tuán)狀物的混合。精鐵礦的預(yù)處理是接下來?；闹匾A段，特別是彭潤(rùn)土和/或者其他添加劑的混合，其中有液體成分的添加。Solution of Ploughshare mixer for iron ore concentrate犁鏵式混合機(jī)在鐵精礦領(lǐng)域的解決方案T

4、he ore concentrate, with dry or liquid additives, is charged continuously to the mixer. The high speed rotating mixing tools, in coordination with the filling level, create an intense motion of the material and rapid dispersion of the particles. The rubbing effect caused by this action assures accur

5、ate dispersion of the liquid additives and prevents the formation of agglomerations or undesirable water spots. The Ploughshare mixing tools have been designed especially for ore mixing. The mixing tools disperse the product, create a rubbing effect and return the product in axial direction, which i

6、s essential for accurate mixing. A long wear life of the exchangeable mixing tools is assured by the special hard metal reinforcement.干的或者帶有液體添加劑的精鐵礦，連續(xù)裝于混合機(jī)。高轉(zhuǎn)速的混合工具，與填料水平相符合，產(chǎn)生物料的強(qiáng)力運(yùn)動(dòng)和顆粒的迅速分散。這種運(yùn)動(dòng)所產(chǎn)生的物料運(yùn)動(dòng)效應(yīng)應(yīng)確保液體添加劑的準(zhǔn)確分散，阻止球團(tuán)的形成和不必要的滴水斑點(diǎn)。犁鏵式的混合工具為礦石混合特殊設(shè)計(jì)混合軸分散物料，產(chǎn)生物料運(yùn)動(dòng)效應(yīng)，再把物料帶回軸的方向，這對(duì)精確的混合是很必要的。易更換

7、的混合工具的長(zhǎng)時(shí)間耐磨壽命是通過特殊硬質(zhì)金屬的加固來保證的。Technical advantage 技術(shù)特點(diǎn)Homogeneous mixing and moistening without the formation of agglomerations or wet spots.均一的混合和濕度，沒有球團(tuán)或者滴水斑點(diǎn)的產(chǎn)生。Assured moisture distribution within a limited range of specified tolerances.在特定的公差限定范圍內(nèi)確保濕度分布。Bentonite savings due to precise and unif

10、tems 犁鏵式混合機(jī)在鐵精礦領(lǐng)域比垂直式的優(yōu)勢(shì)Continuous flow and continuous product discharge because of the defined mixing distance in a horizontal drum between inlet and outlet of the mixer. Every particle has the same retention time.由于混合機(jī)水平滾桶的入口和出口有確定的混合距離，因此混合機(jī)可以實(shí)現(xiàn)連續(xù)混合，并連續(xù)卸料。每個(gè)顆粒都有相同的混合時(shí)間。According to the design of

11、a vertical mixing system, this can not be granted.垂直混合系統(tǒng)的設(shè)計(jì)不具有這種功能Ploughshare mixer guarantees a constant, and continuously discharge to the afterwards Pelletising unit. A like grade and quality of the green pellets is granted.犁鏵式混合機(jī)可以保證為下游的造粒系統(tǒng)提供連續(xù)不斷的物料.并保證每個(gè)生球團(tuán)具有同樣級(jí)別和質(zhì)量On a vertical system the dis

12、charge will be controlled by the weight of the batch; means a constant and unchanging quality can not be granted. 對(duì)于垂直式系統(tǒng)，卸料是由分批重量控制的,這就意味著該系統(tǒng)不能保證連續(xù)不變質(zhì)量.According to the form and arrangement of the mixing elements there is a continuous back mixing of the iron ore particles in a mechanical generated

13、fluid-bed. These back mixing effect (3 steps in direction to the discharge; 2 steps back to the feeding) gives more safety to compensate fluctuation of the dosing systems. The material gets in a three-dimensional movement at the same time there is a axial transport to the discharge.根據(jù)混合機(jī)部件的形式和布置,混合鐵

14、礦石顆粒時(shí)在機(jī)械產(chǎn)生的流化床部分有一個(gè)連續(xù)的回流混合過程.這種回流混合過程(3步是卸料的方向,2步是向入料的方向)將會(huì)更安全的補(bǔ)償定量給料系統(tǒng)的波動(dòng).材料將會(huì)得到三維立體的運(yùn)動(dòng),同時(shí),也會(huì)沿軸向運(yùn)動(dòng)以便卸料.These in a ploughshare mixer generated mechanical fluid bed enlarge the surface of the ore concentrate this promotes uniform mixing of all the individual particles with Betontit and other dry or i

Vertical s

16、ystems are in need of much more height.由于混合機(jī)采用了水平設(shè)計(jì)的混合滾桶,因此,重量輕.而垂直系統(tǒng)則需要更大的高度.Ploughshare mixer for heavy duty application is robust and wear resistance designed.有專門為重型機(jī)械行業(yè)設(shè)計(jì)的犁鏵式混合機(jī)具有堅(jiān)固耐磨的特點(diǎn).The mixing drum and endplates are equipped with a rubber lining (screwed segments-easy to exchange, thickness

17、 32mm); this reduce a build up of the material on the drum as well as vibration. The body of the drum and endplates are protected against wear.混合滾桶和端板里面有橡膠的襯板(螺絲連接且分塊容易更換,厚度32mm);這就減少了材料在滾桶的堵塞和振動(dòng).桶體和端板是被保護(hù)的,耐磨的.Mixing elements are high protected against wear by special and proven coating of tungsten

18、 carbide with high lifetime.混合部件表面是一層高耐磨的特殊材料碳化鎢并具有很長(zhǎng)壽命.Ploughshare mixer ensure a long lifetime and reliable in operation in compare to low maintenance work and costs for the mixer and control. 犁鏵式混合機(jī)確保使用中的長(zhǎng)壽命，和可靠的，同時(shí)混合機(jī)和控制的低維護(hù)工作和費(fèi)用The Ploughshare mixer is a single shaft mixer equipped with heavy d

19、uty bearings in a housing outside of the mixing drum. Only 1 drive with a fixed speed is required. The mechanical discharge controls the filling level, retention time and the throughput of the material by means of adjustable segments. 犁鏵式混合機(jī)是單軸混合機(jī)，在混合桶的機(jī)殼外表面裝有重型軸承。只需要1個(gè)固定速度的驅(qū)動(dòng)。機(jī)械的卸料控制進(jìn)料水平度，混合時(shí)間，通過調(diào)節(jié)可調(diào)單元來控制產(chǎn)品的產(chǎn)量。In compare to a vertical system no we
