What industries can roll dry granulation machines be widely used in?
Date: 2025-10-09Read: 3
The roll type dry granulation machine is a mechanical equipment that adopts the dry extrusion granulation process. Its core feature is to form a dense cake material by double roll extrusion of dry powder material, which is crushed and screened to make particles. The entire process does not require the addition of adhesives or wetting agents. This device has been widely used in multiple industries due to its unique technological advantages. The following is a detailed analysis of its main application industries:
1. Pharmaceutical industry
In the pharmaceutical industry, roller dry granulation machines are widely used for producing tablet pellets and capsule filling pellets. Its advantage lies in the fact that the entire granulation process does not require the use of water or organic solvents, making it particularly suitable for pharmaceutical raw materials that are sensitive to moisture and heat. Through roll pressing technology, drug powder and excipients are compressed into flakes without liquid binder, and then crushed into particles with good flowability. This process not only ensures the purity of the drug, but also avoids the drug degradation problems that may occur with traditional wet granulation. In addition, the particle density of dry granulation is uniform and the disintegration is good, providing ideal material preparation for subsequent tablet pressing or capsule filling.
2. Chemical industry
The chemical industry is another important application area for roller drying granulators. This device is used to produce particles of various chemical products such as catalysts, pigments, detergents, etc. Its dry process is particularly suitable for chemical raw materials that cannot come into contact with water or solvents, such as certain easily hydrolyzed compounds. By rolling granulation, the bulk density of chemical powders can be significantly increased, thereby improving the storage and transportation performance of materials. In addition, the equipment can process more than 20 types of chemical raw materials such as ammonium nitrate, urea, and ammonium chloride, and can customize non-standard equipment to generate multiple product combinations. In chemical production, the dry granulation machine not only improves production efficiency, but also reduces subsequent drying costs by 30% -50%.
3. Food industry
In the field of food processing, the roller drying granulator is mainly used for producing granules for food manufacturing and seasoning granules. Its dry process avoids the risk of microbial contamination that may be introduced by traditional wet granulation and meets food hygiene requirements. This device can make various food ingredients such as milk powder, seasonings, plant extracts, etc. into particles of the required mesh size, significantly improving the flowability and solubility of the materials. It is worth mentioning that the drying granulator performs well in the production of tea granules, capable of compressing tea powder into uniform granules, which not only maintains the original flavor of tea, but also facilitates brewing and use.
4. Other potential application areas
In addition to the main industries mentioned above, the roller dry granulation machine also has potential applications in plastic pellet manufacturing, feed processing, and other fields. Its dry process is particularly suitable for materials that cannot be processed by wet methods, such as certain thermosensitive plastic raw materials. With the continuous advancement of technology, the application scope of this device is expected to further expand.
The roller dry granulation machine has become an important granulation equipment in industries such as pharmaceuticals, chemicals, and food due to its characteristics of no need to add wetting agents, short process flow, low energy consumption, and high particle strength. Its application not only improves production efficiency, but also reduces production costs, providing strong support for product upgrades in various industries.
