原理   Principle

        各種干粉物料從設(shè)備頂部加入，經(jīng)脫氣、螺旋預(yù)壓進(jìn)入兩個平等軋輥，軋輥相對旋轉(zhuǎn)，物料被強(qiáng)制送入兩輥之間，軋輥將物料咬入輥隙進(jìn)行壓縮，物料通過壓縮區(qū)后，物料的表面力和 重力使之自然脫出。脫出后的指條狀團(tuán)塊進(jìn)入碎粒機(jī)由旋轉(zhuǎn)刀排破碎，被破碎的物料進(jìn)入整粒 機(jī)通過滾動刀排使顆粒和部分粉狀物料進(jìn)入旋振篩進(jìn)行篩分。合格品通過輸送機(jī)被送入成品倉。粉狀篩下物料通過輸送機(jī)再次被送回原料倉進(jìn)行二次輥壓，擠壓力的大小不一可根據(jù)造粒操作的需要由液壓油缸的壓力進(jìn)行調(diào)節(jié)。

       通過改變輥面開槽形式，可得到片狀、條狀、扁球狀物料。

Dry material powder is fed from the top of the equipment,de-air,screw-pre-press,enter into the gap between the two rollers that are rotating in opposite direction.The pressed material falls down because of surface tension and gravity when passes through pressing section.The noddles shaped material then enters into breaking machine, been smashed by rotating knife.The smashed material enters into granulator.and then the particles and is part of powder material enters into sieve by the rolling knife, and then the product is separated.The product up to standard Will be conveyed to product silo by conveyor;the material under the sieve should be feedback and should be pressed again.The pressure might adjust by the hydraulic oil cylinder according the requirements of granulation.

Sheet, bar and other shape of product might be procured by choose the relative shape of the groove on the roller.

概述   Description

        GZL系列干法輥壓造粒機(jī)是采用干法擠壓工藝技術(shù)，對含水量10％的粉狀物進(jìn)行壓縮成片，再經(jīng)過破碎、整粒、篩分工藝，使片塊狀物料變成符合使用要求的顆粒狀物料。

        干法輥壓造粒主要是靠外部加壓方式，使物料強(qiáng)制通過兩個反而旋轉(zhuǎn)的輥輪間隙，壓縮成片。在輥壓過程中，物料的實(shí)際密度能增大1.5-3倍，從而達(dá)到一定的強(qiáng)度要求。

Adopts dry pressing technology to pressure material with moisture content of lower than 10％ into sheets and it is processed into required particles through breaking, granules treaming and screening process．

The material is pressed by exterior force, and passes through the gap between the two rollers which are rotating in different directions, and then it pressded into sheets. The mass density of material might increase 1.5-3 times, so to achieve required strength.

特點(diǎn)   Featrures

        物料經(jīng)機(jī)械壓力強(qiáng)制壓縮成型，可以不添加任何濕潤劑，產(chǎn)品純度得到保證。干粉直接造料，無需后續(xù)干燥過程，更有利于現(xiàn)有生產(chǎn)流程的銜接和改造。 

        顆粒強(qiáng)度高，堆積比重的提高較其它造粒方式都更為顯著。尤其適合于增加產(chǎn)品堆積比重的場合。

       可控制環(huán)境污染，減少粉體浪費(fèi)和包裝成本，提高產(chǎn)品運(yùn)輸能力。

        結(jié)構(gòu)緊湊，維修方便，操作簡單，工藝流程短，能耗低，效率高，故障率低，適合原料范圍廣，輥壓力可根據(jù)不同物料自由調(diào)整。

         加料和喂料裝置采用變頻無級調(diào)整控制，自動化程度高，可實(shí)現(xiàn)一人多機(jī)控制，勞動強(qiáng)度低及可長期連續(xù)運(yùn)轉(zhuǎn)等特點(diǎn)。

         主要傳動部件均采用優(yōu)質(zhì)合金材料、不銹鋼材料、鈦材、鉻和其他表面合金制作，大大提高了耐磨損、耐腐蝕、耐高溫及耐壓能力，使該機(jī)具有較長的使用壽命。

The material is forced and to be pressed by mechanical force,without any additional ingredients,so to ensure purity.

The dry material is made into granules directly,no need any further drying process.So it is good for product processing.

The strength of the particles is high,the mass density is increased more apparently compare to other method of granulation,it is especially applicable for to increase the mass density of product.

The pollution of environment is controlled,the wasted powder is reduced,the packaging fee is decreased and the product is easier in transportation.

The structure is compact,the maintenance is convenient,the operation is simple,the process is short,the energy consumption is low,the effciency is high,the probablity of fault is low,the application range is wide,and the pressure of roller might be adjusted freely according to the proerty of material.

The material feeding adopts non-step inverter control,the automation level is high.One operation might control multi-units of machine.The labor intensity is low.and the machine might run continuously in long time.

Adopt high quality alloy,stainless steel,Ti,Cr and other metal for driving parts, the wear-resistance, cossive- resistance,thermo-resistance and pres-sure-resistance is highly increased.The service life is long.

工藝流程   Technological proccess

        原料由加料口通過螺旋輸送機(jī)進(jìn)入斗式提升機(jī)，由斗式提升機(jī)將原料粉末送入振動式原料倉，通過定量加料機(jī)將物料送入變頻式螺旋喂料機(jī)，對物料進(jìn)行預(yù)壓縮，經(jīng)預(yù)壓縮的物料被壓入兩個相對轉(zhuǎn)動的兩對壓輥中間進(jìn)行壓實(shí)，其壓實(shí)力是通過油缸的推力由壓輥傳遞給物料的，被壓實(shí)的片狀物料自動脫槽進(jìn)入破碎機(jī)，將其破碎成大小不均的顆粒體，然后進(jìn)入整粒機(jī)進(jìn)行修整。被修整的顆粒通過帶網(wǎng)孔的篩板被擠壓出來進(jìn)入篩分機(jī)，成品顆粒通過篩分后進(jìn)入斗式提升機(jī)被送入成品倉。篩分下來的粉狀物通過螺旋輸送機(jī)返回原料倉，再次壓實(shí)由此完成一個封閉式循環(huán)。

The material enters into the hopper lifting machine through spiral conveyor from the feeding port,and then it's delivered to vibration material silo. A metered feeder will feed the material into inverter controlled spiral feeder, and the material is then pre-pressed.The pre-pressed material enters into the gap between the two rollers that arerotating in opposite directions,and then it's firmly pressed.The firmly pressing force is transferred to the material through the pushing force of oil cylinder.The firmly pressed material sheet falls into the breaking machine automatically, and been smashed into granules of different sizes,and then enters the granulator to be trimmed.The trimmed granules is squeezed out into the sieve through mesh board.The final product enters into hopper lifting machine,and then it's conveyed to final product silo. The material sieved out should be fed back to the material silo by spiral conveyor,so to perform the next circulation.
