Coating calculators
The five sums a coating run actually needs, worked out in the browser. Nothing is sent anywhere, no sign up, and the formula is printed beside every result so you can check it.
- 01Tablet coating weight gain calculatorHow much dry coating material a batch needs at a target percentage weight gain, including process loss.
- 02Coating dispersion and solids calculatorWater or solvent needed to disperse a ready-mix powder at a given solids concentration.
- 03Coating spray rate calculatorSpray rate per gun and total run time from your dispersion quantity and available process window.
- 04Coating pan speed and tangential velocity calculatorTangential bed velocity from pan diameter and RPM, with the range most film coating runs sit in.
- 05Coating drying capacity and maximum spray rate calculatorHow much water your inlet air can actually carry away, and the spray rate that supports.
- 06Coating dispersion vessel and impeller sizing calculatorVessel volume, diameter and impeller size for the dispersion quantity you are making.
- 07Tablet surface area and coating build-up calculatorSurface area per tablet and coating build-up in mg per square centimetre, which is how enteric coats are specified.
These give you a starting point, not a validated process. Every figure needs confirming on your own pan with your own cores, and the published parameters on each grade page are where we would begin.
