6. TOP LID

Top Lid available on RMG mixing chamber for close or seal properly mixing chamber during entire Dry mixing-Wet Mixing-Kneading process.

Top lid is operable by hand with the help of balancing weight. It can also be operated by means of air cylinder instead of using balance weight. Top lid consist of Food Grade Gasket which assure proper seal of machine from top to avoid any loss during binding process.

Mixing bowl top lid has two openings, one for addition of binder and other for viewing granulation process. An air vent is provided to release pressure which rise during entire process in the mixing chamber during mixing and granulation by a filter of approx 5 micron. It is easily washable for dedicated as per product or used deposable bag.

 

7. Discharge point

 

The discharge port is mounted horizontally into the mixing chamber with vertical downward opening. Granules are unloaded in the FBP container through the discharge port or direct to FBP cell by vacuum transfer system. Opening of discharge port is operated by pneumatic cylinder (compressed air cylinder) that requires approx 3-5 kg/cm² pressure of compress air.

Discharge point in some RMG open only when FBD/FBP container placed at lower of discharge point and container touch with discharge point sensor available at RMG near to discharge point.

 

8. Purging Air

Purging air coming from gasket presents at the impeller and chopper at pressure of 5-6 kg/cm² to preventing contamination. If Purging Air stopped or below than set pressure, then machine will stopped with alarm and chances are Material can enter inside that from where purging air coming it will result in cross contamination.

Purging air is used to flush the industrial process equipment with clean air. Purging Air helps to keep the surfaces of RMG (Granulation Machine) clean and help in maintaining its effective performance.

 

9. Filter Assembly 

Filter assembly is fitted on the top of LID, in this vent air filter is placed which allows the purging air to leave the Mixing chamber and retains the granules inside.

For air vent filter Product dedicated bag, disposal bag or SS Filter (5 to 10 micron size) used as per Product or as per industry or machine model.

 

10. Co-mill

Co-mill fitted at end of discharge point (as per model of RMG). Co-Mill is used for high speed SHREDDING, SIZING, and GRINDING of wet Granules. Its speed and size of screen use as per product specification. Generally size of screen used in co-mill for wet granules 6 mm to 10 mm.

Online CO-Mill on the discharge port that reduces the oversized lumps. It results in a reduction of drying time. As the lumps are small products, they can be uniformly dried at lower temperatures. Hence providing it a longer shelf life and eliminating casing & capping of tablets due to improper drying.
