DH系列干法滚压造粒机   DH Series Dry Roller Pressing Granulator
概述 Descriptions
粉体造粒技术作为粉粒体过程处理的一个***主要分支，随着环保需求和生产过程自动化程度的提高，其重要性日益彰显。“粉状产品颗粒化”已成为世界粉体后处理技术的必然趋势。对粉状产品进行颗粒的强度加工，其意义主要体现在三大方面：
Powder granulation technology as a main branch of the powder process, with the increase of environmental protection requirements and the degree of automation of production process, its importance is increasingly evident. "Powder products" has become an inevitable trend in the world of postprocessing technology. The strength of the powder product is processed, and its significance is mainly reflected in three aspects:
一、降低粉尘污染，改善劳动操作条件。
One, to reduce dust pollution, improve labor operation conditions.
二、满足生产工艺要求，如提高孔隙率和比表面积，改善热传递等。
Two, to meet the requirements of production process, such as improve the porosity and specific surface area, improve heat transfer, etc..
三、改善产品的物理性能（如流动性、透气性、堆密度）避免后续操作过程（干燥、筛分、计量）和使用过程（计量、配料等）出现偏析、脉动、结块、架桥等不良影响，减少污染、改善外观、改善流动性、便于贮存和运输、控制溶解度、控制孔隙率和比表面积等等，为提高生产和使用过程的自动化以及密闭操作创造了条件。
Three, to improve the physical properties of the products (such as liquidity, permeability, bulk density) to avoid subsequent operation process (drying, screening and measurement) and use process (measuring, mixing, etc.) segregation, pulsating, caking, bridging adverse effects appear, reduce pollution, improve the appearance, improve the liquidity, easy storage and transportation, solubility control, to control the porosity and specific surface area and so on, create the conditions for improving the production and use of process automation and closed operation.
DH系列干法辊压造粒机是采用干法辊压工艺技术，对含水量≤5%的粉状物料进行压缩成片或块状，再经破碎整粒、筛分工艺，使片块状物料变成符合使用要求的颗粒状物料。干法辊压造粒主要靠外部加压方式，使物料强制通过两个相对旋转辊轮间隙，强制压缩成片块状，在辊压过程中，物料的实际密度能增大1.5~3倍，从而达到－定的颗粒强度要求。
DH series dry rolling granulator is the dry rolling technology and compressed into tablets or block the content is less than or equal to 5% of the powdery material containing, crushing granulation and sieving, massive materials into in accordance with the requirements of granular materials. Dry rolling granulator mainly rely on external pressure, the material is forced through the gap between two relatively rotating rollers, forced compression block into a film, in the rolling process, the actual density of material can be increased 1.5 times, in order to reach the demands of granular strength.
 
工作原理Working principle
原料经定量加料器均匀送入喂料斗, 压实机利用带有穴眼孔的成对轧辊，彼此留有一定间隙，两者以相同的转速作反向旋转。其中一组轧辊轴承座在机架内不动，而另一组轧辊轴承座则在机架导轨上游动，藉助液压缸施压使彼此紧靠。轧辊表面上有规则地排列许多形状、大小相同的穴眼孔，且波谷对准波谷。而此时干粉状物料从两轧辊上方连续均匀地靠自重及强制喂料进入两轧辊之间，物料先作自由流动，进入咬入区后被轧辊逐渐咬入波谷。随着轧辊的连续旋转，物料占有的空间逐渐减少而被逐步压缩，并达到成型压力***大值。随后则压力逐渐降低，所压得之型块因弹性回复加之自重而脱落穴眼孔而进入碎整粒、筛分装置，所得成品为粒状合格产品，进行过秤包装。而粉料口出来的细粉料和不合格的超大颗粒则由返料绞龙重新进入提升机加料口随同新鲜物料混合加入预加料斗而进入下一轮工艺流程。
Raw materials by quantitative feeder evenly into the feeding hopper, compaction machine is used with a hole of the eyelet pairs of rollers with each other to leave a gap, both with the same speed as reverse rotation. One group of roller bearing housings is not moving in the frame, while the other group of roller bearing housings are moving on the rack guide rail, and the hydraulic pressure cylinder is pressed to close the other. Roll on the surface arranged many shapes, the same size and alignment hole eyelet, trough trough. But this time dry powder material from the top of the two roller continuous evenly by gravity and forced feeding into the two rollers, the material to flow freely, in bite zone is roll gradually bite into the trough. With the continuous rotation of the roll, the space of the material possession gradually decreases and is gradually compressed, and reaches the maximum value of the molding pressure. Then pressure decreases, the pressure type block due to elastic recovery coupled with the weight off hole eyelet into pieces of whole grain, a screening device, the resulting refined granular qualified products, weighing packaging. The fine powder material and the non qualified super large grain are from the back to the ground to the lifting machine feeding port with the fresh material mixed with the pre feeding hopper and enter the next technological process.
