Feed mill planning tool

Feed Mill Capacity Expansion Calculator

Enter current and target tonnes per hour, operating hours and utilisation. See current theoretical and actual annual output, target annual output, incremental tonnes per year and the capacity increase percentage.

How much extra feed can an expansion actually produce?

Convert both the current and the target rate into annual tonnage using the same operating hours, operating days and utilisation assumption, then subtract. The gap between theoretical and actual output is usually larger than owners expect, which means part of a capacity target can sometimes be met by raising utilisation rather than by buying equipment. The percentage increase this tool returns is the figure that should drive the technical capacity review of every process stage, storage system and utility.

Systems requiring capacity review at this step

System	Why it is in scope	Confirm with
Grinding	Rate scales with throughput and falls on fine screens	Measured t/h per screen
Batching & weighing	Cycle time can cap the line before machinery does	Full cycle time log
Mixer	Batch size and cycle time set the feed rate to the press	Batch size ÷ cycle
Pelleting / extrusion	Rate depends on diameter, recipe and conditioning	t/h at your hardest recipe
Cooling	Often limits sustained output in hot, humid conditions	Air volume and ambient case
Conveying	Transfer rates rarely scale automatically with capacity	Rated vs peak transfer
Raw-material silos	Cover days fall in proportion to consumption	Days of cover at new rate
Finished-feed storage	Buffer and dispatch cap sustainable hours	Buffer hours vs shift plan
Packing / bulk load-out	Dispatch rate becomes the ceiling once silos fill	Loading rate and window
Electrical power	Peak demand and transformer rating may not have headroom	Measured peak demand
Steam	Conditioning temperature drops when boiler output is short	Pressure at conditioner

What this tool calculates

Converts current tonnes per hour into theoretical and realistic annual output.
Converts the target tonnes per hour into target annual output at your expected utilisation.
Returns incremental tonnes per year and the percentage capacity increase.
Shows how much of the target could be met by utilisation improvement alone.
Hands the capacity basis to the growth planner and the RFQ.

What it cannot do

It does not size equipment and does not state which machine is undersized.
It does not price the expansion or estimate CAPEX.
It does not confirm that storage, steam or electrical capacity can support the target rate.
It assumes the target rate is achievable at your recipes; that requires technical review.

Who this is for

Established producers whose plant has become the bottleneck
Owners deciding between higher utilisation and new capacity
Teams building the business case for a Phase 2 expansion
Buyers preparing a capacity basis for a manufacturer RFQ

Input definitions

Current capacity (t/h): Entered by you. Default used for the worked example: 8 t/h.
Target capacity (t/h): Entered by you. Default used for the worked example: 15 t/h.
Operating hours per day (h): Entered by you. Default used for the worked example: 16 h.
Operating days per year (d): Entered by you. Default used for the worked example: 300 d.
Current utilisation (%): Availability, changeovers and rate losses combined.
Expected utilisation after expansion (%): Entered by you. Default used for the worked example: 82 %.

Methodology

Theoretical annual output = tonnes per hour x operating hours per day x operating days per year. Actual output applies the utilisation factor. Incremental tonnage = target actual output minus current actual output. Capacity increase = (target t/h - current t/h) / current t/h. Utilisation headroom = current t/h x hours x days x (expected utilisation - current utilisation).

Assumptions

Utilisation covers availability, changeovers, cleaning and rate losses in one factor.
The same operating schedule applies before and after the expansion unless you change the inputs.
Tonnes per hour are entered at your real recipe mix, not at a supplier reference product.
No allowance is made for ramp-up time after commissioning.

How FeedMatch builds and reviews its calculators

Worked example — 8 t/h plant targeting 15 t/h

Inputs

Current 8 t/h, target 15 t/h
16 operating hours per day, 300 operating days per year
Current utilisation 72 percent, expected utilisation 82 percent

Outputs

Current theoretical output 38,400 t/year; current actual about 27,648 t/year
Target actual output about 59,040 t/year
Incremental output about 31,392 t/year
Capacity increase 87.5 percent
About 3,840 t/year available from utilisation improvement alone

How to read it. An 87.5 percent capacity step means every stage, plus storage and utilities, needs a technical capacity review — not just the press. Roughly a tenth of the additional tonnage could come from raising utilisation, which is usually the cheapest tonne on the table.

Limitations

Planning arithmetic only. It is not an engineering study and not a performance guarantee.
A percentage increase says nothing about which stage must be upgraded; run the bottleneck calculator for that.
Storage and utility capacity frequently cap the achievable rate before the process line does.

All figures are indicative planning estimates for budgeting and supplier discussion. They are not quotations, guarantees or professional engineering, nutritional, legal or financial advice. Have results reviewed by the responsible professionals before you commit capital.

Frequently asked questions

How do I calculate a feed mill capacity increase?

Take the difference between target and current tonnes per hour, divided by the current rate, for the percentage step. For annual tonnage, multiply each rate by operating hours, operating days and a realistic utilisation factor, then subtract. Using nameplate rates without a utilisation factor overstates both the current baseline and the expansion benefit.

Is higher utilisation cheaper than more capacity?

Almost always, where the headroom exists. Reducing changeovers, raising availability and extending shifts add tonnes with little or no capital. This tool shows how much of your target that route could cover before equipment is considered.

Does this calculator tell me which machine to buy?

No. It quantifies the capacity step and lists the systems that require a technical capacity review. Which stage limits your plant is established by the bottleneck calculator and confirmed by measured production data and supplier engineering.
