1.概述

本机为干法辊压造粒机组，是吸收国外造粒机新技术的改进型产品。该机结构特点是：安装了带有机械震动装置的预连续加料器与强制喂料螺旋加料斗相结合的喂料系统 ，保证了喂料的连续性、充分性与均匀性，这是至关重要的一步。在成对轧辊上刻有均布弧槽，有利于物料咬入轧辊，工作时形成弧槽密封腔（带），也有利于物料的压实，降低了机组成形压力与主机负荷，提高了轧片生产率。 该机还配置了轧片成形液压自动补偿加压装置，视镜窗等。粉状物料经斗式提升机后，从加料、螺旋脱气输送、轧片、切碎、筛分至粒状产品，可以一次性完成全过程。 该机利用成对轧辊，彼此留有一定间隙(可调)，两者以相同的转速作反向旋转。其中一组轧辊轴座固定，另一组轧辊轴座滑动，以助于液压缸施压彼此紧靠。轧辊表面有规则地排列许多形状、大小相同的弧槽，根据物料对象压缩比的不同，选择采用一轧辊弧槽的波谷正好对准另一轧辊的波谷。两轧辊呈现水平平行状态，粉粒状物料从两轧辊上方连续、均匀地靠自重和强制喂入两轧辊之间，当物料进入咬入去后逐渐被轧辊咬入，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，并达到成型压力的******值，随后，则压力逐渐降低，所压得之团块，因弹性回复加其轧片自重而脱落轧辊弧槽，接下来进入切碎装置并筛分至粒状产品。 特点： 无需任何添加剂，干粉直接制粒。 ▲颗粒强度可以调整。通过调节轧辊的压力，控制成品强度。 ▲循环操作，实现连续生产。 ▲成品产量高。无干燥工艺,常温造粒,一次成形。成套设备、布局合理、技术先进。 我们为用户提供总体设计、技术指导、成套供货、设备调试、试车投产一条龙服务。 适用物料： 肥料：硫酸钾、氯化钾、俄罗斯红钾、NPK复混肥、氯化铵、硝酸钾、磷酸一铵、磷酸二铵、硫酸铵、碳酸氢铵。 2.粉体材料：草酸铁、氰脲酸三聚氰胺、抗氧剂、溴氯海因、氰化钠、二氯异氰尿酸钠、三氯异氰尿酸钠、氰尿酸、漂粉精、氧化锌、氧化铅、碳酸钾、碳酸锶、氯化钙、磷酸氢钙、偏硅酸钠、正硅酸钠、冰晶石、氟化铝、刹车粉、橡塑助剂、白炭黑、活性炭、铝酸钙、重钙、普钙、光卤石、磷矿粉、金属粉末、填料、饲料添加剂、砒虫啉、烟酸、烟酸胺、医药中间体、炼钢助剂、融雪剂、环保材料等。

2.设备概况

◆轧片机：是对原料施加压力，经两平行轧辊转动将原料轧制成片，提高了原料的堆比重。上、下两轧辊间用齿轮啮合传动，轧辊对物料施加的压力经液压系统完成。

◆脱气槽：是暂存原料定时排出脱气的部分。搅拌桨绕脱气槽的中心线旋转，以排挤出原料中的空气，破除原料的起拱现象。

◆螺旋送料器：是给轧片机强制送料的部分，其作用是在轧片机前对物料进行预压缩，提高体积比重，以满足轧片机的 需要。

◆碎粒机：是对片状物料进行粉碎的部分，粉碎机有旋转齿和固定齿，经过粉碎，片状物料就变成了不规则粒状和粉状的混合物。

◆整粒机：分一次和二次整粒。一次整粒使不规则粒状物料成形，颗粒大小趋于一致。二次整粒对筛分后大于成品的颗 粒进行二次成形。

◆振荡筛：是对经过一次整粒的粒、粉混合物进行筛分的过程，符合要求的成品进入成品仓。第一层筛的筛上物进入二次整粒机，整粒后进入成品仓，第三层筛下物经过刮板式输送机送回脱气槽。

3.造粒原理

各种干粉物料从设备顶部加入，经脱气、螺旋顶压进入对辊，在对辊极大的挤压力作用下使物料产生塑性变形而被压缩成片状。片状物料在经过破碎、整粒、筛分等过程，得到颗粒状产品。通过改变辊面开槽形式，可得到片状、条状、扁球状物料。挤压力的大小可根据造粒操作的需要由液压油缸的压力进行调节。

1.Descriptions

This series of dry roll compacting granulator is first developed by our company,using an advanced dry granulating technique. Through the physical process of com pressing, crushing and screening, powder materials of low density and poor fluidity will be made into granules of high density and good fluidity, meeting different stand ards without dust pollution. This set of equipment has filled in the gaps of technology in our country. Now, according to different requirements and different materials,we can supply complete sets of equipment , single machine , or fittings of different specifications . Besides , we offer varieties of services such as granulating test for different materials, special designs, installation assistance, debug direction and so on. We can also granulate the materials for customers.

2.Components

◆ Compactor: With certain pressure , the materials will be rolled into slices under the action of double rollers . Thus the bulk density of the materials will be increased. There being the gear drive between upper and lower rollers, the pressure will be given to the materials through hydraulic system.

◆ Deaerating tank: It's used for removing the gas in the materials. The propeller rotates around the center line of the deaerating tank in order to remove the gas contained in the materials. So there's no phenomenon of materials pushing up.

◆ Screw feeder: It's used for feeding the materials into the compactor. The function is to pre-compress the materials before they enter the compactor. Thus the bulk density of the materials will be increased so as to meet the need for the compactor.

◆ Crushing equipment: It's used for crushing the slice materials . There's rotating gear and fixed gear equipped on the compactor . So after the crushing process, the slice materials will be turned into the mixture of irregular granules and powders.

◆ Granule reorganizing equipment: There's primary reorganizing process and secondary reorganizing process . Through the primary reorganizing process, irregular materials will be shaped into granules of similar size . Then , after a screening process, there will remain a small amount of granules which have a larger size than required. These granules will be given a secondary reorganizing process.

◆ Vibrating screen: It's used for screening the mixture of granules and powder after the primary reorganizing process . Granules that can meet the requirements will enter the finished product tank . The remaining granules of a larger size on the first layer of screen will be given a secondary reorganizing process , after which they will also enter the finished product tank. After falling off the third layer of screen , the granules of a smaller size will be sent back to the deaerating tank through the flight conveyor to be mixed with the raw powder materials.

3.Principle

Dry powder materials will be spirally pressed from the top into the gaps between the double rollers after gas removing . Then under the action of the huge extruding power from double rollers , the materials will be compressed into slices . Then after the processes of crushing , reorganizing and screening ,slice materials will be turned into granules or pellets. Different shapes of materials such as slices,strips, oblate balls etc. can be achieved by changing the groove forms of the roller surface. The extruding power can be adjusted by hydraulic cylinder according to different requirements.

4.Features

◆ 1.Powder materials are compressed into granules through mechanical force without adding any moisture so as not to destroy the chemical features of the raw materials . The whole process will not reduce the effective content of the materials . So the purity of the product can be ensured.

◆ 2.The whole technological process is very simple with low energy consumption and large output . Cycling operation makes process automation possible. So it's fit for large-scale continuous manufacturing.

◆ 3.Powder materials can be compressed into granules directly without any follow-up process. So it's good for joining and reforming the present manufacturing processes.

◆ 4.Compared with other granulating methods, this set of equipment can achieve products with high intensity and high bulk density. So it's especially fit for those materials whose bulk density is to be raised. The product intensity can be adjusted by adjusting the rollerpressure.

◆ 5.The whole process is adjustable with a large scale of application. The extruding power can be adjusted through hydraulic cylinder.

◆ 6.The whole process is enclosed without adding any additive . Powder materials can be turned into granules directly . So high purity of the product can be achieved. Besides, there's little dust pollution.

◆ 7.In the whole set of equipment , all the parts contacting materials are made of stainless steel or titanium alloys . So good antiseptic function can be achieved.

◆ 8.PLC control available

（ 注：以上参数只作参考，具体参数有待针对具体物料而定。 ）

GZL-X 型造粒机和 GZL-M-X 型造粒机的区别如下(X=1,2,3,4,5,6,7,8)：

GZL-X 型造粒机从料仓加料后，物料会进入横向的螺旋挤压送料，轧辊是上下摆放的，螺旋正对上下两轧辊的中心，将料强制挤入轧辊之间。经过轧辊的挤压，成片状从轧辊的另一侧出来，进入破碎、整粒、过筛、包装过程。

GZL-M-X 型造粒机从料仓加料后，物料直接进入一对横向摆放的轧辊之间，经过轧辊的挤压，从轧辊的下面出来片状物料，进入破碎、整粒、过筛、包装过程。

(Notes:The figures above are for reference only.According to different materials to be granulated,the technical parameters may be different. )

The difference between GZL series dry granulator and GZL-M series dry granulator is as follows:

GZL series: Dry powder materials are spirally pressed into the gaps between the double rollers, which are fixed vertically. Then the materials will come out in the form of slices from the other side of the double rollers before they are crushed, reorganized, screened and packed.

GZL-M series: Dry materials are directly fed into the gaps between the double rollers without being spirally pressed. The double rollers are fixed horizontally. Then the materials will come out as slices from under the double rollers before they are crushed, reorganized, screened and packed.
