Press From the press data sheet

Plates in the Pack plates

Filtration Area per Chamber m²

Both faces of one chamber, as the data sheet gives it.

Cake Volume per Chamber L

The chamber volume on the data sheet for the cake thickness you run.

Cloths per Plate cloths

Count them as your press is dressed: one cloth over both faces, or one per face.

Cake & Running From a cake sample and the plant log

Wet Cake Bulk Density t/m³

Weigh a known volume of discharged cake.

Dry Solids in the Cake %

Press Cycles per Day cycles

Operating Days a Year days

Cloth Life cycles

Cycles a cloth set lasts on this press and slurry, from your own records.

Dry Solids Discharged per Day

— t/day

Chambers x chamber volume x cake density x cake solids x cycles a day

The press figures come from its data sheet and the cake figures from your own samples; the tool has no typical value for any of them. Chambers are one fewer than plates, because each chamber lies between two plates. Cake per cycle assumes every chamber fills; a press that discharges soft or part-filled cakes makes less, so check the cake volume against a weighed discharge. Solids loading is the dry solids of one cycle spread over the filtration area. Cloth use is the cycles a year over the life your cloths reach, times the cloths in the press, rounded up; it counts worn cloths only, not cloths damaged in handling. **This is plant arithmetic, not press selection: it does not size a press for a slurry or predict cycle time.**
