Tablet Press Dwell Time Calculator
Calculate the actual dwell time of a tablet press based on compression parameters, optimize tablet quality, and ensure consistent tablet strength.
The final thickness of the compressed tablet.
Please enter a valid thickness.
The force exerted by the tablet press cam on the punch.
Please enter a valid force value.
The radius of the tablet press punch head.
Please enter a valid radius.
The angular extent of the compression zone in the cam.
Please enter a valid angle.
The radius of curvature of the tablet press cam profile.
Please enter a valid radius.
The rotation speed of the tablet press turret or main shaft.
Please enter a valid speed.
Calculated Dwell Time
Enter values above to calculate.
Formula: Dwell Time = (Cam Angle / (360 × Shaft Speed)) × 60
