0.8–1 T/H Grain Mill for Chicken Feed in Ireland

From Purchased Feed to On-Farm Grain Processing

Previously, the farm purchased finished feed from local suppliers. This arrangement was convenient, but it offered limited flexibility when ingredient prices changed or the owner wanted to adjust the feeding program. Buying whole grain and processing it on-site introduced another option: the farm could separate grain purchasing from feed preparation and decide when to grind according to its actual consumption.

The planned production volume was approximately 3 tons of ground grain per day. That requirement did not justify a large industrial grinding system operating continuously. Instead, the customer needed a machine that could process the daily batch within a manageable working period and leave sufficient time for mixing, pelleting, cleaning and routine maintenance.

A single animal feed hammer mill also reduced the scope of the initial investment. The farm could continue using its existing equipment while gaining control over the grinding stage, which directly affects the consistency of the mash entering the mixer and the pellet mill.

SFSP56*40 Hammer Mill Selected for the Farm

RICHI recommended the SFSP56*40 water-drop-type hammer mill for the customer's grain preparation requirements. Its high-speed rotor drives replaceable hammers against the incoming material, reducing grain size as the particles pass through the selected screen. The machine is suitable for dry cereal ingredients commonly used in poultry feed formulations.

Actual throughput depends on the grain being processed, its moisture content, screen aperture and the fineness required. The rated output should therefore be treated as a selection reference rather than a guaranteed rate for every material. For a farm processing around 3 tons daily, an indicative throughput of 0.8–1.0 T/H provides a reasonable basis for planning several hours of grinding, subject to commissioning tests and operating conditions.

Making Better Use of Irish Grain Supplies

Barley and wheat are familiar ingredients in Irish livestock feeding, and both can form part of poultry diets when properly formulated. Maize may also be used, although its availability and price can depend on supply arrangements and imports. The farm's purchasing strategy therefore combines locally available cereals with other ingredients obtained through established feed suppliers.

• Barley provides starch and other nutrients but contains more fiber than maize, making particle-size control important.
• Wheat is a useful energy ingredient and can be ground to suit the intended feed form.
• Maize contributes energy and can be incorporated when commercially and nutritionally appropriate.

The hammer mill focuses on these cereal ingredients. Protein meals, oils, mineral sources and vitamin supplements are handled separately and added during mixing. This arrangement avoids unnecessary grinding of materials that are already supplied in a suitable form.

For the farm, the benefit is not that every ingredient becomes cheaper automatically. Rather, the owner gains another purchasing and processing option. Whole grain can be bought when quality and price are favorable, stored under suitable conditions and ground in batches according to the feeding schedule.

Particle Size: Matching the Grinding Setting to the Feed

The customer initially focused on a particle-size range of approximately 1.5–2 mm for the cereal fraction used in grower and finisher feed. This was a starting target, not a fixed setting for every formulation. Broiler starter diets may require finer grinding in some production systems, while older birds can benefit from different particle distributions depending on the complete ration and whether the feed is supplied as mash, pellets or crumbles.

The SFSP56*40 uses a replaceable screen to control the size of particles leaving the grinding chamber. Selecting a suitable screen requires balancing three factors: the desired particle distribution, the throughput needed and the characteristics of the grain. A finer screen may increase grinding resistance and reduce output, so the smallest possible particle size is not necessarily the best commercial choice.

After grinding, the cereals are mixed with protein ingredients, oils and a properly formulated vitamin-mineral premix. If the mash is subsequently pelleted, particle uniformity can support more consistent mixing and pellet formation. The final diet must still be balanced by a qualified poultry nutritionist; grinding alone does not establish nutritional adequacy.

How the Grinder Fits into the Existing Feed Setup

The farm deliberately retained its mixer and small pellet mill. The new grinder was introduced upstream, giving the operator a more controlled route from whole grain to prepared mash.

1. Whole cereals are inspected for foreign objects and unsuitable moisture before entering the grinding process.
2. Barley, wheat or maize is fed into the hammer mill in controlled batches.
3. The ground material is transferred to the existing mixing equipment.
4. Protein sources, oils, minerals and premixes are added according to the approved feed formulation.
5. The prepared mash is used directly where appropriate or transferred to the existing pellet mill for further processing.

This sequence keeps the new machine's role clear. It does not replace mixing, pelleting or cooling equipment, and it does not independently produce complete poultry feed. Instead, it improves the preparation of the grain fraction on which those downstream operations depend.

Before installation, the farm needed to check the available floor space, electrical connection, material-transfer route and dust extraction arrangements. A preliminary layout should allow space for the grinder, inlet and discharge connections, dust-control equipment and access for screen and hammer replacement. The final footprint and foundation details should follow the approved equipment drawings rather than a generic floor-area estimate.

Power, Staffing and Daily Operation

The selected machine has a 37 kW main motor and requires an electrical supply suitable for the motor's starting method and operating load. The farm's electrician needed to verify the existing three-phase supply, protective devices, cabling and control arrangements before commissioning. Any connected conveyors and dust-collection equipment must also be considered when checking the total installation load.

For a small on-farm setup, one trained operator can generally supervise a grinding batch while following the site's material-handling and safety procedures. Depending on the farm's workflow, the same employee may also undertake other feed-preparation tasks when the grinder is not running. Actual staffing depends on how grain delivery, mixing, bagging and poultry-house feeding are organized.

Dry grinding does not normally require process water. Raw-material moisture nevertheless needs attention because excessively wet grain can impair flow, affect grinding performance and create storage problems. The operator should monitor motor current, unusual vibration, bearing temperature, screen condition and hammer wear. Regular inspection helps identify changes in performance before they disrupt the feeding schedule.

Because cereal dust can be combustible under suitable conditions, dust collection, housekeeping, electrical protection and ignition-source control are essential. The installation must comply with the applicable Irish and European workplace and machinery safety requirements.

What Changed for the Farm

The main operational improvement was greater control over the timing and consistency of grain preparation. The owner could grind a batch when it was needed rather than depending entirely on deliveries of pre-ground ingredients. This made it easier to coordinate grain purchasing with the farm's consumption and available storage.

The existing mixer and feed pellet machine remained useful, avoiding the cost and disruption of replacing equipment that could still perform its intended functions. The farm also gained the flexibility to test different grinding settings and ingredient combinations without committing to a fully automated feed factory.

The owner estimated that producing part of the feed in-house could reduce costs by around 18% under favorable purchasing and operating conditions. That figure should be assessed against the complete cost of production, including whole-grain prices, electricity, labor, maintenance, storage losses and the costs of other feed ingredients. Savings will vary with market prices, formulation and equipment utilization; they are not guaranteed by the grinder alone.

Shipping to Ireland and Installation Assistance

The equipment was shipped from China by sea, with the Port of Dublin serving as the planned entry point before onward road transport to western Ireland. The customer coordinated local delivery and prepared the installation area in advance, reducing the work required after the machine arrived.

RICHI provided equipment documentation and remote technical guidance to support installation by the farm's technician. The work included checking the machine's position, confirming the motor connection, reviewing the feeding and discharge arrangements and preparing the operating procedures.

Before routine production, the operator needed to run the machine under controlled conditions and verify the resulting particle distribution and throughput using the actual grain supply. This commissioning stage was important because screen selection and material characteristics can affect the result more than a nominal capacity figure alone suggests.

Why a Standalone Grain Mill Made Sense

For this Irish poultry farm, the purchase was a measured step toward greater control over feed preparation rather than an attempt to replicate a large commercial mill. The SFSP56*40 gave the farm a dedicated grinding stage while preserving the value of its existing mixing and pelleting equipment.

Other farms may require a different configuration. A smaller operation with limited daily consumption may be better served by a lower-capacity machine, while a commercial feed manufacturer running multiple shifts may need a larger grinder, automated conveying and integrated dust collection. Grain type, target particle size, annual feed demand and operating hours should all be considered before selecting a model.
