Rotary<\/span> tablet<\/span> machines<\/span> (RTM),<\/span> unlike<\/span> eccentric<\/span> ones,<\/span> have<\/span> a<\/span> large<\/span> number<\/span> of<\/span> matrices<\/span> and<\/span> punches.<\/span> The<\/span> matrices<\/span> are<\/span> mounted<\/span> in<\/span> a<\/span> rotating<\/span> matrix<\/span> table.<\/span> The<\/span> pressure<\/span> in<\/span> the<\/span> RTM<\/span> increases<\/span> gradually,<\/span> which<\/span> ensures<\/span> a<\/span> soft<\/span> and<\/span> uniform<\/span> pressing<\/span> of<\/span> the<\/span> tablets.<\/span> rTMS<\/span> have<\/span> high<\/span> productivity<\/span> (up<\/span> to<\/span> 0.5<\/span> million<\/span> tablets<\/span> per<\/span> hour).<\/span>\nThe<\/span> technological<\/span> cycle<\/span> of<\/span> tableting<\/span> on<\/span> RTM<\/span> consists<\/span> of<\/span> a<\/span> number<\/span> of<\/span> sequential<\/span> operations:<\/span> Filling<\/span> the<\/span> matrices<\/span> with<\/span> tableted<\/span> material<\/span> (volumetric<\/span> dosing<\/span> method).<\/span> Actually<\/span> pressing.<\/span> Ejection.<\/span> Dropping<\/span> pills.<\/span> The<\/span> operations<\/span> are<\/span> performed<\/span> sequentially<\/span> in<\/span> automatic<\/span> mode.<\/span> The<\/span> upper<\/span> and<\/span> lower<\/span> punches<\/span> slide<\/span> along<\/span> the<\/span> guides<\/span> (caps)<\/span> and<\/span> pass<\/span> between<\/span> the<\/span> pressing<\/span> rollers,<\/span> exerting<\/span> simultaneous<\/span> pressure<\/span> on<\/span> them.<\/span> The<\/span> pressure<\/span> increases<\/span> and<\/span> decreases<\/span> gradually,<\/span> which<\/span> leads<\/span> to<\/span> uniform<\/span> and<\/span> soft<\/span> pressing<\/span> of<\/span> the<\/span> tablet<\/span> from<\/span> above<\/span> and<\/span> below.<\/span> Depending<\/span> on<\/span> the<\/span> type,<\/span> such<\/span> machines<\/span>

this<\/span> time,<\/span> since<\/span> the<\/span> matrix<\/span> hole<\/span> 7<\/span> has<\/span> come<\/span> under<\/span> the<\/span> funnel<\/span> \/.<\/span> The<\/span> RTM<\/span> loading<\/span> device<\/span> consists<\/span> of<\/span> a<\/span> hopper<\/span> loading<\/span> funnel<\/span> and<\/span> a<\/span> feeder<\/span> dispenser,<\/span> fixed<\/span> motionless<\/span> on<\/span> the<\/span> machine<\/span> bed.<\/span>\nThe<\/span> hopper<\/span> ensures<\/span> the<\/span> continuity<\/span> of<\/span> the<\/span> flow<\/span> of<\/span> the<\/span> tableted<\/span> material.<\/span> For<\/span> uniform<\/span> supply<\/span> of<\/span> poorly<\/span> bulk<\/span> materials<\/span> to<\/span> the<\/span> feeder,<\/span> hopper<\/span> funnels<\/span> can<\/span> be<\/span> equipped<\/span> with<\/span> agitators,<\/span> augers,<\/span> agitators.<\/span> The<\/span> feeder-dispenser<\/span> is<\/span> designed<\/span> for<\/span> directing<\/span> and<\/span> dosing<\/span> the<\/span> tablet<\/span> mass<\/span> into<\/span> the<\/span> pressing<\/span> zone.<\/span> Pressing<\/span> operation.<\/span> As<\/span> soon<\/span>

The<\/span> lower<\/span> punch<\/span> is<\/span> also<\/span> slightly<\/span> raised<\/span> and<\/span> pushes<\/span> the<\/span> tablet<\/span> out<\/span> of<\/span> the<\/span> matrix.<\/span>
