干式造粒工作原理Working Principle:

根據(jù)機械擠壓造粒工藝原理，將配置好的，具有一定結(jié)晶水的干粉狀或微細晶體狀原料，加壓成薄皮，隨后經(jīng)造粒系統(tǒng)，通過篩

網(wǎng)制成所需大小的顆粒。

原料可以通過手工或真空上料機加入料斗，經(jīng)水平放置的送料螺桿疏松和壓縮，被推至兩擠壓輥輪的咬如口；通過垂直放置的壓

輥，將原料加壓成薄皮(壓輥的速度決定物料在輥壓區(qū)停留的時間)。

物料所需的壓力通過液壓裝置線性傳送給壓輥，液壓裝置可保持一定的預(yù)壓力，垂直排列的壓輥可保持物料密度的一致性。

根據(jù)不同顆粒要求，設(shè)備造粒系統(tǒng)中的網(wǎng)篩目數(shù)大小可相互更換。

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.

干法造粒優(yōu)點Merits of GH Series Dry Granulator:

將粉體原材料直接制成滿足用戶要求的顆粒狀產(chǎn)品，無需任何中間體和添加劑，造粒后產(chǎn)品粒度均勻，推積密度顯著增加，改善

流動性，即控制了粉塵飛揚，又減少了材料浪費，便于儲存，可控制溶解度、孔隙率和比表面積等。

特別適用于傳統(tǒng)濕法制粒無法造粒的，濕熱條件小不穩(wěn)定的藥物進行造粒。

干法造粒工藝可替代濕法制粒流水線投入，節(jié)省人力、物力、財力，是節(jié)能環(huán)保的新型設(shè)備。

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.
