The production of products is the basic task of the use of instruments and equipment, to a certain extent, improve the product yield and molding rate will effectively improve the processing efficiency of the machine, thereby improving the economic benefits of the entire manufacturer, the roller dry granulator is mainly used for pharmaceutical, word material and other industries granulation needs, the selection of high-quality alloy materials made of, Compact structure, convenient maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate, then how can we use to improve its yield?
1. Material formula.
The principle of the roller dry granulator is to directly press the dry powder into thin sheets and then crush and grain, so the high and low yield in the dry granulation process is mainly directly related to the material formula, and the yield of the material with good compressibility is higher.
2. Tablet strength.
There is a great connection with the strength of the pressed sheet and the structure of the granulation and the speed of crushing, the strength of the pressed sheet is related to the size of the pressure and the feeding and pressing speed, the feeding process of the dry granulator is also a pre-pressing process and degassing process, if the air in the material is drained as much as possible, and the material has a reservation area, so that the pressed sheet will not appear intermittently. In this way, under the condition of other conditions unchanged, the yield will be relatively improved.
3, granulation knife structure.
The granulation structure will directly affect the particle yield, if the pressed sheet in the granulation box frequency crushing, this will also reduce the yield, dry granulation machine with rolling type, so that the material quickly rolled out of the screen, and improve the yield, the slower the crushing speed the higher the particle yield, in the condition of not blocking the mesh as slow as possible.
4. Discoloration problem.
The color of the stock material will be different from the original powder after granulation. Because the surface area of the powder is larger than the surface area of the particle, the reflection of light will be different. In addition, the accumulation degree of the pressed particles will be increased compared with the original powder, so the color of the particles will be deepened. The pressure acting on the press wheel is not only the pressure of the oil pump, but also related to the feed speed and the press speed, under the condition that the pressure and the press speed are certain, the faster the feed speed, the greater the pressure between the press wheels, the smaller the vice versa, the slower the press speed is under the same condition that the pressure and the feed speed are certain, the greater the pressure between the press wheels, and the smaller the vice versa. Therefore, the user should choose a pressure and speed according to the actual condition of the material when using the antisilver dry granulator, so as to improve the product yield on the basis of ensuring the product function.
