干式造粒工作原理Working Principle:

根据机械挤压造粒工艺原理，将配置好的，具有一定结晶水的干粉状或微细晶体状原料，加压成薄皮，随后经造粒系统，通过筛

网制成所需大小的颗粒。

原料可以通过手工或真空上料机加入料斗，经水平放置的送料螺杆疏松和压缩，被推至两挤压辊轮的咬如口；通过垂直放置的压

辊，将原料加压成薄皮(压辊的速度决定物料在辊压区停留的时间)。

物料所需的压力通过液压装置线性传送给压辊，液压装置可保持一定的预压力，垂直排列的压辊可保持物料密度的一致性。

根据不同颗粒要求，设备造粒系统中的网筛目数大小可相互更换。

It is based on the principle of mechanical squeezing and granulation. Which are usually crystal mixtures or powder mixtures

with some crystal water, are squeezed into flake-shape before they go through the granulation system. The sieve unit is then

used to obtain certain sized final products.

Raw materials are put into the hopper by hａnd or vacuum conveyer. The horizontal screws then deliver the raw materials into

the squeezing unit, which includes vertical compression rollers to squeeze raw materials into flake-shape. How long the raw

materials stay in the squeezing unit depends on the speed of the compression rollers.

There is a hydraulic device transferring pressure linearly to the compression rollers and this device can maintain a certain

level of pressure itself. The vertical arrangement of the compression rollers can keep the consistency of the product's density.

Screen in the screening untie can be changed base on different requirements of the mesh size of final product.

干法造粒优点Merits of GH Series Dry Granulator:

将粉体原材料直接制成满足用户要求的颗粒状产品，无需任何中间体和添加剂，造粒后产品粒度均匀，推积密度显著增加，改善

流动性，即控制了粉尘飞扬，又减少了材料浪费，便于储存，可控制溶解度、孔隙率和比表面积等。

特别适用于传统湿法制粒无法造粒的，湿热条件小不稳定的药物进行造粒。

干法造粒工艺可替代湿法制粒流水线投入，节省人力、物力、财力，是节能环保的新型设备。

Powder raw materials are made into granular product directly based on users' requirements, without any intermedium or

additive. The final product is even granular with good quality of density. During the smooth process, the material dust well the

solubility, porosity and specific surface area are controllable.

It is specialized in the area where traditional wet granulator are not suitable in, and materials are unstable under sticky

circumstances.

GH Series Dry Granulator is energy economic and environmental friendly latest-type equlpment. It is much better than

traditional wet granularors in many aspects, such as saving labors and material resources, and also saving money.
