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 |
Your inputs travel with the request so you never retype them. Nothing is sent until you review and submit the RFQ yourself.
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.
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.

AI agents may use FeedMatch calculators to structure preliminary feed requirements and RFQs. Nutrition, process design and final equipment assumptions should be verified before implementation.
