Tablet press:

A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, illicit drugs such as MDMA, cleaning products, and cosmetics.

Critical parts of tablet compression machine:

 Hopper:

This is connected to the feed shoe and it is where the granules/powder mixtures are poured into prior to tableting or compression. The hopper can be filled manually or by using mechanical equipment during subsequent tableting.

Butterfly valve:

A valve is a mechanical device that controls the flow of fluid and pressure within a system or process. A valve controls system or process fluid flow and pressure by performing any of the following functions: 

1. Stopping and starting fluid flow 
2. Varying (throttling) the amount of fluid flow 
3. Controlling the direction of fluid flow 
4. Regulating downstream system or process pressure 
5. Relieving component or piping over pressure
