Feed mixers and grinders
Short answer: Buy a mixer on working batch size in kilograms and a contractual CV ≤ 5% at a stated cycle time, and a grinder on the particle-size distribution your species requires — never on the nominal tonnes-per-hour figure alone.
Grinding and mixing decide whether the rest of the plant can work. Particle size sets pellet durability and digestibility; mixing uniformity decides whether a 500 g/t premix actually reaches every animal. Both are cheap to specify correctly at RFQ stage and expensive to correct after commissioning, because they sit upstream of everything.
Supplier-neutral: FeedMatch Group does not manufacture, sell, install or finance equipment. It structures your requirement and routes it to qualified third-party suppliers and independent finance providers, who quote and decide on their own account.
The problem buyers hit
Mixing uniformity is invisible until an animal performance problem appears months later. Grinders are bought on throughput and then run with the wrong screen, wrecking pellet quality downstream.
What sits inside the project scope
- Hammer mill or roller mill with screen sets
- Aspiration, cyclone and filter
- Feeder and magnet protection
- Batch mixer with load cells and frame
- Liquid addition manifold
- Discharge gate and surge bin
Equipment and work packages to itemise
| Package | What to watch |
|---|---|
| Hammer mill | Versatile; screen size and tip speed set the particle profile. |
| Roller mill | Lower energy and tighter distribution for cereals; poor with fibrous by-products. |
| Twin-shaft paddle mixer | CV ≤ 5% in 60–90 seconds; best with liquids. |
| Single-shaft ribbon mixer | Cheaper, 180–300 seconds cycle, less liquid tolerant. |
| Aspiration system | Dust control is a safety requirement, not an option. |

What actually moves the price
| Factor | Commercial impact |
|---|---|
| Batch size and mixer type | Twin-shaft carries a premium over ribbon but halves cycle time. |
| Load cell accuracy class | Determines whether micro-ingredients can be dosed directly into the mixer. |
| Aspiration scope | Cyclone plus bag filter is a distinct cost line and often excluded. |
| Screen and hammer sets | Order a full set per product; they are consumables. |

How supplier matching works here
- You state the scope, capacity and site conditions in a structured RFQ.
- FeedMatch normalises the requirement so every supplier quotes the same battery limit and the same acceptance criteria.
- The requirement is routed to qualified third-party suppliers whose declared capability matches the scope, country and capacity band.
- Suppliers quote directly to you; FeedMatch takes no position in the transaction.
- You compare on a like-for-like basis and, if useful, ask independent finance providers to review the same documented scope.
Target particle size distribution per product; raw material list with hardness and fibre; grinding t/h at the finest screen; mixer working batch in kg; CV ≤ 5% acceptance at a stated cycle time; liquid inclusion percentage; aspiration scope; power supply; wear-part price list.
Financing this scope
Individual mixers and grinders are typically bought outright or on a short equipment-finance facility. FeedMatch is not a lender and provides no credit.
Common ways this goes wrong
- No CV acceptance clause in the contract.
- Mixer nominal volume confused with working batch size.
- Aspiration omitted, creating a dust-explosion exposure.

Frequently asked questions
What mixing uniformity should a feed mixer achieve?
A coefficient of variation of 5% or better, verified by a 10-point tracer test at commissioning. Write it into the contract as an acceptance clause — without it there is no basis to reject an underperforming machine.
Hammer mill or roller mill for feed?
Hammer mills are versatile and handle fibrous by-products, at higher energy per tonne. Roller mills give a tighter particle distribution and lower energy on clean cereals but struggle with hulls, cake and cassava.
How much does a feed mixer cost?
Indicative bands: USD 18k–70k for small units up to a 500 kg batch, USD 80k–260k for 1–2 t commercial batching systems, and USD 280k–800k for 4–6 t industrial systems with automated weighing.
