Adjustment parameters Dry granulation efficient machine dry granulation suitable for use in a variety of materials, so the high pressure dry granulator, the feeding, compression, crush, whole speed can be adjusted, so that the operation efficiency of dry The requirements of the granulator will be higher. Generally, the manufacturer will provide a relative parameter before leaving the factory, but in actual use, it should be adjusted according to the material characteristics and the required degree of particle solidity and particle size. Generally speaking, the liquidity is better. For good materials, the feeding speed can be slower, and the pressure on the easy-to-form material can be smaller. For the larger particles, the crushing speed can be slower, as long as the screen mesh is not blocked. You can adjust one parameter as appropriate to change other parameters. In short, to adjust the parameters, as long as the meaning of each parameter can be grasped, in the actual operation according to the specific circumstances of the adjustment, it is also to continue to test and sum up experience, to achieve good results.
DRY yield of the granulator: high dry granulating machine principle is directly dry compressed into a sheet and then pulverized and sieved, so the dry granulation in high yield and low, the first material has a direct formulation The relationship between the yield of the compressible material is high; the strength of the pressed piece and the tool structure of the granulation and the speed of the pulverization have a great relationship. The strength and pressure of the tablet and the feeding, The pressing speed is related to the feeding process. The feeding process is also a pre-pressing process and a degassing process. If the air in the material is exhausted as much as possible, and the material has a pre-staying zone, the pressed piece will not be intermittent, so that In other cases, the yield will be relatively increased; the granulated tool structure will directly affect the yield of the granules. If the pressed granules are pulverized in the granulation box, this will also reduce the yield, and the pebbles Referring to the foreign granulation method, the rolling type is adopted, so that the material is quickly rolled out from the screen, and the yield is improved, and the slower the pulverization speed, the higher the yield of the granule, and the case where the mesh is not blocked. Slow down as much as possible. Domestic standards as long as the yield rate of 30% efficient dry granulator has met the requirements. (Based on starch as standard 20-60 mesh) Material color change during granulation: the color of the general material will be different from the original powder after dry granulation, because the surface area of ​​the powder is larger than the surface area of ​​the particle, so the reflection of light It is also different. After the pressed particles increase the bulk density of the original powder, the color of the particles will also deepen. Under normal circumstances, the pressure on the pressure roller will become darker and the color will become deeper. The pressure is not only the pressure of the oil pump, but also the feed speed and the tableting speed. Under the condition of constant pressure and tableting speed, the faster the feeding speed, the greater the pressure acting between the pressure rollers, and vice versa. The pressure is slower when the pressure and the feed speed are constant, and the pressure acting between the pressure rollers is larger, and vice versa. Therefore, when using the high-efficiency dry granulator, the user should select a good pressure and speed according to the actual conditions of the material, so as to improve the yield of the product on the basis of ensuring the performance of the product.
Roundness of dry granulated granules: The roundness of dry granulated granules is slightly worse than wet granulation, but the roundness of dry granulation and the thickness of the granules and the form of pelletizing knives There is a certain relationship (in addition to the material itself), the roundness of the particles can be increased by changing the thickness of the sheet. Generally, the thickness of the pressed sheet can be appropriately adjusted according to the particle size, so that the roundness of the particles after the whole grain is adjusted. To be better, the structure of the whole knife can be improved, and the roundness of the particles can also be improved. In short, I hope that before choosing the high-efficiency dry granulator, the customer can send us some materials. Let's do some experiment to see if the particles can meet the customer's needs, because each material and every recipe will be There are different results, so that customers can choose the more suitable equipment.
