Common problems in the use of domestic dry granulators

There are many developers of dry granulators across the globe. The main granulators may include the oscillating granulator. These granulators are excellent in appearance. They require proper checking and maintenance. However, other types of dry granulators do not require too much checking and maintenance.

When it comes to the common problems in the use of domestic dry granulators, then there are quite a few. Nonetheless, these problems need proper attention. It does not matter what sort of dry granulator you use, like oscillating granulator machine, the problems will remain the same.

The roll is easy to wear and damage

The surface structure of the oscillating granulator roll is easy to damage. The dimensional parameters are the teeth with the circumference. The tooth groove width size and its depth have to be taken into account. There are diverse roller surface structures. Each of them has a pressing effect, depending on the materials. By the characteristics of the material, they could be separated into three-roller forms. These roller forms may include typical medicine form, western material form as well as particular material form. The material of the roll is made up of stainless steel. The entire surface is handled with nitride gas, and the depth of the layer is quite thick. For that reason, the roll’s surface has wear and tear resistance. It can have good resistance from corrosion, which is a huge issue of misalignment of the roll. It is triggered mainly because of high pressure and low development accuracy.  

The cool water is present within the roll of leaking cool water. A sealing device is present onto the static cooling water duct and the rotating roll. Nevertheless, after use, the damage or leakage issue will show up during the high pressure. Right now, there are a few manufacturers who have improved the roll structures. In this way, the cooling water will go to the surface of the roller directly. Not just that, the reduction of the temperature of the roll’s surface will be performed efficiently. Furthermore, the leakage possibility will fall to a minimum.

In simple words, the selection of the materials and technological innovation should be appropriately performed. Both these things play an imperative role when it comes to high-pressure monitoring and roll wearing and damaging.

Large Dust Production

The main issue of the domestic dry granulation is large dust production. There is diverse manufacturers design equipment without considering the problem of dust particles. It has to be updated from the stipulations and ideas of pharmaceutical production. Adjustment should be taken into account. The dust particles generated during the production of medicines must be taken out. Pharmaceutical equipment must be improved to meet the needs and wants.

When it comes to the generation of dust, it is imperative to pay attention to the vibration of the equipment. The vibration can maximize when the large dust particles start producing. Therefore, when manufacturing equipment, the manufacturers must consider the overall structure and manufacturing accuracy. Find the source of the vibration that caused the vibration and reduce the vibration from the dry granulator.
