干法辊压式制粒机原理   Principle

        各种干粉物料从设备顶部加入,经脱气、螺旋预压进入两个平等轧辊,轧辊相对旋转,物料被强制送入两辊之间,轧辊将物料咬入辊隙进行压缩,物料通过压缩区后,物料的表面力和 重力使之自然脱出。脱出后的指条状团块进入碎粒机由旋转刀排破碎,被破碎的物料进入整粒 机通过滚动刀排使颗粒和部分粉状物料进入旋振筛进行筛分。合格品通过输送机被送入成品仓。粉状筛下物料通过输送机再次被送回原料仓进行二次辊压,挤压力的大小不一可根据造粒操作的需要由液压油缸的压力进行调节。

       通过改变辊面开槽形式,可得到片状、条状、扁球状物料。

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.

干法辊压式制粒机概述   Description

        GZL系列干法辊压造粒机是采用干法挤压工艺技术,对含水量10%的粉状物进行压缩成片,再经过破碎、整粒、筛分工艺,使片块状物料变成符合使用要求的颗粒状物料。

        干法辊压造粒主要是靠外部加压方式,使物料强制通过两个反而旋转的辊轮间隙,压缩成片。在辊压过程中,物料的实际密度能增大1.5-3倍,从而达到一定的强度要求。

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.

干法辊压式制粒机特点   Featrures

        物料经机械压力强制压缩成型,可以不添加任何湿润剂,产品纯度得到保证。干粉直接造料,无需后续干燥过程,更有利于现有生产流程的衔接和改造。 

        颗粒强度高,堆积比重的提高较其它造粒方式都更为显著。尤其适合于增加产品堆积比重的场合。

       可控制环境污染,减少粉体浪费和包装成本,提高产品运输能力。

        结构紧凑,维修方便,操作简单,工艺流程短,能耗低,效率高,故障率低,适合原料范围广,辊压力可根据不同物料自由调整。

         加料和喂料装置采用变频无级调整控制,自动化程度高,可实现一人多机控制,劳动强度低及可长期连续运转等特点。

         主要传动部件均采用优质合金材料、不锈钢材料、钛材、铬和其他表面合金制作,大大提高了耐磨损、耐腐蚀、耐高温及耐压能力,使该机具有较长的使用寿命。

 

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.

干法辊压式制粒机工艺流程   Technological proccess

        原料由加料口通过螺旋输送机进入斗式提升机,由斗式提升机将原料粉末送入振动式原料仓,通过定量加料机将物料送入变频式螺旋喂料机,对物料进行预压缩,经预压缩的物料被压入两个相对转动的两对压辊中间进行压实,其压实力是通过油缸的推力由压辊传递给物料的,被压实的片状物料自动脱槽进入破碎机,将其破碎成大小不均的颗粒体,然后进入整粒机进行修整。被修整的颗粒通过带网孔的筛板被挤压出来进入筛分机,成品颗粒通过筛分后进入斗式提升机被送入成品仓。筛分下来的粉状物通过螺旋输送机返回原料仓,再次压实由此完成一个封闭式循环。

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.
