Roll Compactor Machine for Dry Granulation

Lodha International LLP 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. Roller 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 the roll compactor equipment. This process compacted micro-powders into solid compacts or sheets, sometimes known as chips or flakes, are then transferred 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 a 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 optimising 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 optimisation of the granulation process for the tablet section equipment. It helps in producing dust-free pellets that fulfill export needs.

Salient Features of Lab Roll Compactor:

• Adheres to current good manufacturing practices.
• All contact parts, except for the rollers, are made from S.S. 316.
• Extremely portable, with options for plain, water-jacketed, and flameproof versions.
• A variable frequency AC motor drives the feed screw, equipped with a safety clutch between the transmission and the feed screw.
• Compacting rollers are constructed of tool steel, hard-chromed, and polished to a mirror finish, also known as electroless nickel plating (ELNP).
• twin-shaft gearbox drives the rolls, connected to a separate drive unit to synchronize the torque applied to each roll.
• The pre-compression container allows things to roll without sliding or leaking.
• The pre-densifier screw, which is produced from highly finished AISI SS-316 stainless steel, can be rectangular or cylindrical.
