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

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

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。高轉(zhuǎn)速的混合工具，與填料水平相符合，產(chǎn)生物料的強力運動和顆粒的迅速分散。這種運動所產(chǎn)生的物料運動效應(yīng)應(yīng)確保液體添加劑的準確分散，阻止球團的形成和不必要的滴水斑點。犁鏵式的混合工具為礦石混合特殊設(shè)計混合軸分散物料，產(chǎn)生物料運動效應(yīng)，再把物料帶回軸的方向，這對精確的混合是很必要的。易更換

10、tems 犁鏵式混合機在鐵精礦領(lǐng)域比垂直式的優(yōu)勢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.由于混合機水平滾桶的入口和出口有確定的混合距離，因此混合機可以實現(xiàn)連續(xù)混合，并連續(xù)卸料。每個顆粒都有相同的混合時間。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.并保證每個生球團具有同樣級別和質(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)混合機部件的形式和布置,混合鐵

14、礦石顆粒時在機械產(chǎn)生的流化床部分有一個連續(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)將會更安全的補償定量給料系統(tǒng)的波動.材料將會得到三維立體的運動,同時,也會沿軸向運動以便卸料.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.由于混合機采用了水平設(shè)計的混合滾桶,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.有專門為重型機械行業(yè)設(shè)計的犁鏵式混合機具有堅固耐磨的特點.The mixing drum and endplates are equipped with a rubber lining (screwed segments-easy to exchange, thickness

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.桶體和端板是被保護的,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. 犁鏵式混合機確保使用中的長壽命，和可靠的，同時混合機和控制的低維護工作和費用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. 犁鏵式混合機是單軸混合機，在混合桶的機殼外表面裝有重型軸承。只需要1個固定速度的驅(qū)動。機械的卸料控制進料水平度，混合時間，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
