Lodha Machine is a leading manufacturer and exporter of roll compactor machines, completely designed for use in the pharmaceutical industry and other sectors like food, chemical, cosmetics, pesticides, biotech, herbal, and nutraceutical industries. Our roll compactor machines are built to meet the various needs of these industries, assuring high efficiency and quality in the dry granulation process.
The dry granulation procedure mainly depends on roll compactor equipment. This process compacted micropowders into solid compacts or sheets, sometimes known as chips or flakes, then transferred them between two counter-rotating rolls of material. After compaction, the size of these chips or flakes is reduced to the desired granule size using machines like the oscillating granulator machine, multi machine, communicating mill, or sizing machine. Choosing the appropriate filter size is important for preventing the occurrence of unused particles, and the final granule size is decided by the sieve used. Screening machines may also be employed to remove dust from the granules, improving their quality. Additionally, the roll compactor machine allows for the re-compacting or recycling of separated fines.
Fine or crystalline powder is loaded into the stainless steel roll compactor machine's charging hopper at the beginning of the compaction process. From there, the powder is fed through a pre-compacting chamber into the compacting zone of the compacting rollers using a vertical feed screw. The powder is forced to pass precisely between the rollers at an adjustable speed, controlled by an AC variable frequency drive (AC VFD). This results in the formation of hard chips or flakes from the fine powder. By optimizing the roller and feed screw speed for the desired quality of flakes, increased production can be achieved while maintaining a consistent speed ratio.
The specific qualities of the powder or substance determine the roller surface to use in your tablet section machine. Our technical team, which has wide expertise in roll compactor machines, may suggest the best roller surface for a particular product. We provide the chance to perform trials with your material in our facility to help in product development, evaluation, and optimization of the granulation process for the tablet section equipment. It helps in producing dust-free pellets that fulfill export needs.
Operating a roll compactor machine is characterized by its efficiency and simplicity. The stainless steel roll compactor machine's charge container is initially filled with fine or crystallized powder. The vertical feeding screw transports the powder from a preliminary compression chamber into the compacting zone, where it is compressed between the compacting rollers. An AC Variable Frequency Drive (AC VFD) precisely controls the feed screw's speed, maintaining optimal feeding and constant pressure delivery.
Once the powder enters the compacting rollers, it undergoes controlled compression at an adjustable speed, effectively forming firm chips or flakes. Adjusting the speed of both the rollers and feed screw allows for optimal production of high-quality flakes. The compacting rollers, coated with electroless nickel plating, assure a smooth and efficient compression process while preventing rust and extending the machine's lifespan.
After the initial compaction, the chips or flakes are further reduced to the desired granule size using machines like the oscillating granulator, multimill, communicating mill, or sizing machine. The appropriate sieve selection is valuable in determining the final granule size, while screening machines help remove any dust, improving the overall quality of the granules. The roll compactor machine also allows for the re-compacting or recycling of separated fines, maximizing efficiency and minimizing waste.
In conclusion, Lodha Machine's stainless steel roll compactor machines are designed to deliver exceptional performance, reliability, and efficiency in the dry granulation process. Whether used in the pharmaceutical industry or other sectors, these machines produce high-quality granules that fulfill the high requirements of current production processes.
