Weighing, Dosing & Loss-in-Weight Feeding calculator

Feeder Shift Mass Capacity Calculator

Check whether a feeder can deliver the required ingredient mass in a shift. Enter qualified sustained flow, net feeding hours and the required mass.

What this calculator does

  • Check whether a feeder can deliver the required ingredient mass in a shift.

Formula used

  • Shift capacity = Qualified sustained kg/hr × Net feeding hours
  • Capacity margin = Shift capacity − Required ingredient mass

Inputs explained

  • Qualified Sustained Feed Rate: Proven sustained mass flow for this material and setup.
  • Net Available Feeding Time: Scheduled hours after stops that interrupt actual feeding.
  • Required Ingredient Delivery: Ingredient mass needed in the same production window.

How to use the result

  • Best suited to ingredient shift planning, feeder capacity reviews.
  • Does not establish torque, minimum feed rate or short-term dosing accuracy.

Common questions

  • Should hopper refill always be subtracted? Subtract only time that interrupts feeding; continuous-feed refill is already part of a demonstrated sustained rate.
  • Can I use a catalog maximum? Only if it is qualified for your material, screw arrangement and required accuracy.
  • What happens when the qualified rate or available time is zero? Available capacity is zero. Any positive required mass appears as a delivery shortfall; zero required mass gives a zero margin.
  • Can parallel feeders be combined? Sum their independently qualified mass rates when they can operate simultaneously into the same process.
