conditions have cohesive properties and be compressible for example addition of a binder and or adjustment of the amount of binder may be used to facilitate compressibility in an exemplary embodiment the active agent s is pre blended with a diluent binder and other excipients in a mixing vessel such as for example a v blender upon mixing the resulting blend may be fed typically by gravity to the hopper of a roller compactor in a typical roller compaction process a vertical feed screw i e a u201c vfs u201d facilitates feeding the blend into the compactor by deareating the blend and forcing it between the rolls a horizontal feed screw i e a u201c hvs u201d within the hopper feeds the material to vfs the feed screw speeds rpm of the vfs and hfs may be adjusted to optimize the amount of blend going into the roll nip region of the roller compactor in one exemplary embodiment the ratio of vfs hfs speed is about 3 1 the blend is densified and granulated as it passes between two high pressure rolls that compress the blend controlling and monitoring roll speed which impacts dwell time for the material to be compacted by the rolls roll pressure which is the pressure applied to the rolls and or roll gap which is a function of the pressure applied to the rolls and the material passing between them facilitates maintaining uniformity and batch to batch reproducibility the compacted material is collected and passed thru a mill for particle sizing once sized the compacted material may be tableted directly or blended with additional ingredients and tableted roller compaction is exemplary.
