5 TPH feed mill: what the capacity really means before you request quotes

Nominal capacity versus real average output

A rated capacity is valid only against the conditions it was measured under. Change any one of these and the real rate moves:

Plan the plant on effective tonnes per operating hour, not the nameplate rate, and record that assumption in the RFQ so suppliers answer against your basis.

• Recipe: high-fibre, high-fat or high-inclusion-by-product formulas pellet slower than a standard maize-soya broiler ration
• Pellet diameter: small diameter (2–3 mm) pellets reduce throughput sharply against 4–6 mm
• Conditioning: steam quality, retention time and target conditioning temperature all shift the achievable rate
• Grinding fineness: a finer grind ahead of the press moves the bottleneck upstream to the hammer mill
• Cooling and drying: the cooler, not the press, sets the sustainable rate in hot and humid climates
• Changeovers, flushing, batching gaps, cleaning and planned maintenance

Annual tonnage at 5 TPH

Annual output depends on shifts and uptime far more than on the rated figure. Use the same basis for every proposal:

• One shift, moderate uptime: around 12,000 tonnes per year
• Extended shifts and higher uptime: up to about 30,000 tonnes per year
• State planned operating hours per day, days per week and weeks per year in the RFQ
• Reserve headroom for growth, seasonal peaks and future product ranges before fixing the capacity

Process line scope at this size

A 5 TPH line is usually a compact tower or semi-tower layout: intake and cleaning, a single hammer mill, one batch mixer, a pellet press with conditioner, a counterflow cooler, crumbler where crumbles are produced, screening and bagging or bulk load-out. Liquid addition is often limited to a mixer-stage fat line. Automation is typically batch control with manual micro-ingredient addition unless medicated feeds require otherwise.

Raw material and finished feed storage

Raw material storage at this size is frequently a mix of flat storage and a small silo battery. Decide days of cover per key ingredient before layout: maize and soya cover drives most of the civil cost. Finished feed storage should reflect delivery frequency and the number of simultaneous products held.

Utilities and connected load

Connected load is modest relative to larger plants but grid stability matters more than headline capacity. Confirm supply reliability, backup generation and steam source early — an unreliable supply invalidates the whole design and is a common cause of underperformance after commissioning.

Staffing and operating model

Commonly a small operating team per shift with combined roles across intake, production and dispatch. Quality control is usually a basic on-site laboratory plus external analysis, and maintenance is largely in-house with supplier support for the press.

Budget framing

Budget framing at this size is dominated by scope, not by the press. Civil works, steel, storage, electrical supply, installation and commissioning routinely exceed the process equipment package. Ask each supplier to price the same scope boundary so the comparison is meaningful.

What your RFQ must state for this capacity

• Reference recipe (or recipes) the capacity is measured against
• Pellet diameters and the share of production per diameter
• Mash, pellet, crumble and any post-pelleting treatment volumes
• Operating hours per day, days per week, weeks per year
• Guaranteed capacity at the reference condition, and expected derate on the hardest recipe
• Grinding, mixing, pelleting, cooling and load-out capacities as separate figures
• Ingredient intake rate and finished-feed dispatch rate
• Automation level, weighing accuracy and batching cycle time
• Connected load, installed power and expected specific energy consumption
• Exclusions: civil works, steel, electrical supply, installation, commissioning, spares
