We are professional factory specializing in the production of granulation machine. One is DH series granulator, for this kind, the final granules shape is 2-4mm irrgelar shape granules. The other kind is DG model, the final granules shape is Oblate shape around 5.1mm. DH series has the hydraulic system, so DH has the larger pressure of press. But they have the same working principle which is using the double roller to make the powder materials into granules. DH series granulator machine is suitable for almost kinds of dry powder with moisture less than 1%. But DG model machine is only suitable for some crystal , single-formular with moisture2-3%, such as ammonium sulfate, ammonium chloride, salt , etc. Please can you tell me the moisture of your raw material? 1. We have different models of granulator,please tell me your capacity(t/h) and the granule size. Then according to your capacity, i will suggest you our suitable model. 2. According to your Raw materials---- I need to know the details of your raw materials, Such as raw material mositure,density and so on. If you can send us 25kg of sample for test, it will be great!! 3.About our granulation line working principle, I will introduce you the whole granulating process (it takes DH650 for example): 1). We use mixer to the raw material for more uniform feeding.---Mixer 2). We use bucket elevator lift the material up to the silo.----Bucket elevator and Silo 3). The DH650 granulator compress the raw material by double rollers, it mainly depending on the mechanical pressure to compress the dry powder, so the hardness of granular is very high.---------DH650 granulator (including three parts: dosage screw feeder, forced feeder and flaking machine.) 4). Then we get the bar shape products, just as following: Hello, Please tell what is your raw material and what capacity you need?
