A useful pellet plant proposal begins with useful project information. If a buyer sends only a target capacity such as “5 tons per hour,” the supplier has to guess raw-material conditions, pellet specifications, operating hours, utilities, site constraints, storage, packaging, and automation. Those assumptions may produce a quotation quickly, but the quotation can change substantially once the real project is understood. Preparing a structured project brief before requesting proposals makes different suppliers easier to compare and reduces redesign later.
1. Define The Raw Materials
List every raw material you expect to process, not just the main one. For wood and biomass projects, identify sawdust, chips, shavings, bark, straw, agricultural residues, or mixed materials. For feed projects, list grains, meals, bran, minerals, liquids, and other ingredients. For fertilizer projects, identify the main organic or mineral inputs.
Describe whether materials arrive individually or already blended. If the composition changes by season or supplier, explain the expected range. The process can only be designed correctly when the supplier understands what enters the factory.
2. Provide Moisture Information
Moisture strongly affects drying, grinding, pelleting, cooling, storage, energy demand, and finished-product quality. Provide measured moisture values where possible rather than estimates. If moisture changes during the year, give the typical minimum and maximum.
A dry sawdust line can be much simpler than a line receiving wet wood chips. The difference can determine whether a dryer, fuel system, larger dust collection, and additional storage are required. Moisture information should therefore be available before the supplier prepares a serious proposal.
3. Describe Raw-Material Size And Form
Tell the supplier whether material arrives as logs, chips, shavings, coarse fiber, powder, meal, granules, or another form. Provide the approximate maximum size and the normal size distribution. Photographs with a scale and representative samples can be useful for unusual materials.
This information determines whether chipping, crushing, hammer milling, screening, magnetic separation, or other preparation is needed before pelleting.
4. Define The Finished Pellet
State the target pellet diameter, length range, moisture, density, durability, fines level, and any relevant customer or market standard. If several sizes will be produced, identify each one and estimate the production share. The pellet specification affects die selection, conditioning, cooling, screening, and changeover planning.
Also explain the final use. Fuel pellets, animal feed pellets, fertilizer pellets, and other pellet products can have very different process requirements even when the requested diameter is similar.
5. State Capacity In More Than One Way
Hourly capacity is important, but annual production target is equally useful. Tell the supplier the desired tons per hour, planned operating hours per shift, number of shifts, days per year, and expected utilization. A 5 t/h plant operating one shift has different storage, labor, maintenance, and utility planning from a 5 t/h plant running continuously.
- Target hourly output
- Expected annual production
- Hours per shift
- Shifts per day
- Operating days per year
- Expected seasonal peaks
These figures help the supplier judge whether redundancy, buffer storage, or larger equipment is justified.
6. Explain Product Mix And Changeovers
If the factory will produce several formulas, raw-material combinations, pellet diameters, or packaging formats, explain how often changes are expected. Frequent changeovers can influence bin quantity, cleaning requirements, recipe control, die changes, screen changes, and production scheduling.
A proposal for one stable product may not be suitable for a factory that changes product several times per shift. Flexibility should be designed intentionally.
7. Provide Site Dimensions And Building Information
Send an accurate site plan or building drawing when available. Include length, width, clear height, column positions, doors, floor levels, pits, existing foundations, roof structure, and access roads. Mark areas that cannot be used and identify any existing equipment that must remain.
If the building has not been constructed, provide land dimensions and local height or planning restrictions. This allows the supplier to compare vertical and horizontal layouts before civil design begins.
8. Confirm Electrical Supply
Provide voltage, frequency, phase, available transformer or service capacity, and any known limitations on motor starting. If the site has an existing transformer, give its rating and current loads. Large pellet plants can have substantial installed power, and electrical conditions can affect motor and control-panel selection.
For international projects, do not assume that the supplier will guess local standards correctly. Electrical information should be confirmed before manufacturing.
9. List Available Utilities
Depending on the process, the plant may need steam, compressed air, water, fuel, hot air, thermal oil, or other utilities. State what is already available and what must be supplied as part of the project. For steam, provide pressure and capacity if known. For drying, identify available fuel types and local fuel costs where possible.
Utility information affects both equipment selection and operating cost, so it should not be left until installation.
10. Define Storage Requirements
Tell the supplier how many days of raw-material storage and finished-product storage you need. Explain whether materials arrive by truck, bag, bulk container, loader, or conveyor. Identify whether separate raw materials must remain segregated.
Storage is often a major part of plant footprint and investment. If it is omitted from the first proposal, the final layout may need substantial changes later.
11. Specify Packaging And Dispatch
Provide bag size, big-bag requirements, bulk loading needs, desired bags per hour, palletizing expectations, and labeling requirements. If multiple products use different packaging, identify each format. Packaging can become a plant bottleneck when it is selected after the pellet line capacity has already been fixed.
Also explain how finished products leave the factory. Truck loading, warehouse staging, container loading, and bulk dispatch all affect layout.
12. State The Desired Automation Level
Explain whether you want manual local control, central PLC control, recipe management, automatic batching, production reports, remote diagnostics, or integration with existing systems. Automation should match labor availability, operating complexity, quality requirements, and budget.
Do not simply request “full automation” without defining what operators should and should not do. A good proposal should describe the control philosophy in practical terms.
13. Describe Local Environmental And Regulatory Conditions
Tell the supplier about ambient temperature, humidity, altitude, dust restrictions, noise limits, emissions requirements, fire rules, seismic conditions, wind loads, and any local standards that could affect equipment or structures. These conditions can change motor selection, enclosure protection, ventilation, dust collection, building design, and safety systems.
If requirements are not yet known, identify that uncertainty so it can be resolved before final engineering.
14. Define Your Scope And Budget Priorities
Explain which parts of the project you expect the supplier to provide: process equipment, steel structures, electrical panels, boiler, compressor, storage, packaging, installation, commissioning, and training. Also identify where you prefer local supply, such as civil construction or field cabling.
If there is a realistic budget range, sharing it can help engineers choose between alternatives instead of developing a technically attractive solution that is financially impossible. The supplier should still explain the trade-offs rather than reducing scope silently.

The more complete the information at the beginning, the more useful the first process design, equipment list, layout, and budget will be.
What If Some Information Is Not Available Yet?
It is normal for early-stage projects to have unknowns. Mark them clearly instead of guessing. A professional supplier should identify which unknowns are critical before quotation, which can remain assumptions for a preliminary proposal, and which must be confirmed before manufacturing. This allows the proposal to develop in stages without pretending that uncertain inputs are final.
For example, a preliminary layout may be possible before the final building drawing, but manufacturing should not begin until critical dimensions are confirmed. Early transparency is safer than late redesign.
Final Recommendation
Before asking for a pellet plant proposal, prepare a concise project brief covering raw materials, moisture, particle size, pellet specifications, hourly and annual capacity, product mix, site dimensions, electrical supply, utilities, storage, packaging, automation, local conditions, scope, and priorities. Attach drawings, photographs, laboratory data, or samples where they add useful information.
A detailed brief does not lock you into one design. It gives suppliers the same starting point so their technical and commercial proposals can be compared fairly. It also exposes which suppliers ask intelligent follow-up questions and which ones simply send a standard quotation. That alone makes good preparation one of the most valuable steps in a successful pellet plant procurement process.
