500 KG Feed Mixer in Nigeria

Why a 500 kg Batch Mixer Fits the Oyo Feed Plant

The customer's annual broiler-feed requirement is approximately 3,000 tonnes. A much larger one- or two-tonne-per-batch mixer would have increased installation height, supporting conveyor capacity and batch inventory without solving an immediate production requirement. The 500 kg SLHJ1A fits the existing grinder, manual ingredient preparation and small-scale bagging arrangement more closely.

At 500 kg per batch, every two completed batches equal one tonne of mixed feed. In a practical 1–2 T/H production line, the customer handles approximately two to four batches per hour once ingredient weighing, loading, active mixing, discharge and downstream handling are considered. Across an eight-hour production day, this corresponds to roughly 8–16 tonnes of plant throughput, or about 2,400–4,800 tonnes of theoretical annual capacity at 300 operating days.

The plant's approximately 3,000 T/Y target therefore falls within a realistic operating range without requiring the mixer to run continuously at its maximum possible batch frequency.

SLHJ1A Project Configuration

The 500 kg figure refers to material weight per batch rather than a universal volume-based fill level. Bulk density changes between maize meal, wheat by-products, soybean meal and groundnut cake, so the mixer should be loaded according to both batch weight and usable working volume. Overfilling can reduce material movement even when the motor still turns normally.

Feed Ingredients Used in the Oyo Project

The customer produces one main product through this mixing section: broiler mash feed. The formula changes according to raw-material prices and nutrient specifications rather than following one permanent percentage combination.

Maize is used as an important energy ingredient, while soybean meal and properly tested groundnut cake can supply part of the protein requirement. Wheat bran or wheat offal may be incorporated where the formulation permits, together with vegetable oil, limestone, phosphate, salt, amino acids and vitamin-mineral premix.

This raw-material profile fits the Oyo feed sector, where maize, soybean products and other locally traded feed ingredients are readily relevant to poultry production. The mixer does not determine the nutritional formula; its job is to distribute the ingredients selected by the nutritionist as uniformly as the process allows.

From 1–3 mm Ground Grain to a 500 kg Batch

Whole maize and other ingredients requiring size reduction first pass through the existing hammer mill. For this broiler mash project, major ground components are generally prepared to an approximately 1–3 mm particle range before entering the batching section.

Macro ingredients are weighed first. Smaller ingredients and premixes are dosed separately to improve measurement accuracy. Where a micro-ingredient represents only a very small fraction of the 500 kg batch, the customer can prepare a carrier preblend before adding it to the main mixer. This reduces the risk of placing a very small quantity directly into a large mass of coarse material and expecting instantaneous distribution.

If oil is included, it should be sprayed or distributed through a suitable liquid-addition arrangement rather than poured into one location. Heavy localized liquid addition can form wet agglomerates and increase residue on the mixer wall or paddles.

Mixing Time Is Not the Same as Complete Batch Cycle

The SLHJ1A is designed for rapid paddle mixing, so the active mixing stage is much shorter than the 10–12 minutes associated with some slow vertical mixers. For this project, active mixing is normally evaluated in an approximately 1–3 minute window after the required ingredients are loaded.

However, the complete production cycle is longer. Ingredient weighing, conveyor transfer, manual micro-dosing, liquid addition, mixer discharge and bagging all take additional time. This is why a 500 kg mixer can fit naturally into a 1–2 T/H feed line even though the paddles themselves complete the actual mixing action in only a few minutes.

Final mixing time should be confirmed through production trials rather than extended automatically. Mixing for longer does not necessarily continue improving uniformity and, with some ingredients, unnecessary handling can contribute to segregation.

How the Plant Checks Mixing Uniformity

Visual appearance alone cannot prove that a feed batch is uniformly mixed. Maize meal and protein meals may look evenly distributed while salt, minerals or premix still vary between samples.

The customer therefore uses periodic sampling from discharged batches and can evaluate an appropriate tracer or nutrient marker when validating the mixer. Sample position, number of samples and laboratory method need to remain consistent if results are to be compared over time.

RICHI does not use one unsupported uniformity percentage as proof for every formula. Actual mixing performance depends on batch filling level, ingredient particle size, density differences, liquid addition, loading sequence and equipment condition.

Raw-Material Quality Matters Before Mixing

The mixer machine cannot correct poor raw materials. Maize and oilseed cakes arriving at the Oyo facility need inspection for moisture, mold, foreign material and storage condition before they are accepted into feed production.

This is especially important for maize and groundnut-derived ingredients because warm, humid storage conditions can create significant mycotoxin risk. A perfectly mixed batch containing contaminated material is still an unsuitable feed batch.

The customer's operating procedure therefore separates raw-material quality control from mixing control: acceptable ingredients first, accurate weighing second, controlled mixing third and finished-feed sampling after discharge.

Integration with the Existing Grinder and Bagging Section

The SLHJ1A is installed between the existing batching section and the customer's mash-feed bagging equipment. Ground ingredients move into weighing and dosing, enter the 500 kg mixer, and discharge into a receiving hopper before packaging.

This arrangement allows the customer to retain usable equipment rather than purchasing a complete feed mill. It also makes future expansion easier to evaluate. If production later exceeds approximately 1–2 T/H, RICHI would first review grinding capacity, ingredient weighing, mixer batch frequency, conveying and bagging before recommending a larger mixer.

Simply replacing the SLHJ1A with a one-tonne mixer would not double plant production if the grinder or bagging system remained the actual bottleneck.

Shipping the 500 Kg Feed Mixer to Oyo State

The 500 Kg Feed Mixer in Nigeria is prepared for export from Qingdao, China, with Lagos Port Complex at Apapa used as a practical container gateway before inland delivery toward Oyo State.

Before shipment, RICHI checks the feed inlet height, mixer support structure, 11 kW electrical connection, upstream weighing arrangement, discharge hopper and downstream bagging interface. Because the customer is installing one mixer in an operating workshop, matching these interfaces is more important than replacing equipment that remains suitable for the 1–2 T/H plant.

A 500 Kg Feed Mixer in Nigeria for a 1–2 T/H Feed Plant

This 500 Kg Feed Mixer in Nigeria project uses one RICHI SLHJ1A with an 11 kW motor, 1 m³ effective volume and approximately 500 kg batch capacity. Maize and other major ingredients are generally ground to approximately 1–3 mm before weighing and mixing, while micro-components are dosed separately. The mixer supports an existing approximately 1–2 T/H broiler mash feed system with an annual production target of around 3,000 tonnes.

For another feed producer selecting a 500 kg mixer, RICHI Machinery needs the formula ingredients, bulk densities, percentage of micro-additives, liquid-addition requirement, required batches per hour, existing grinder capacity, weighing method and downstream discharge arrangement. These details determine whether the SLHJ1A is correctly matched to the complete plant rather than selecting a mixer from batch weight alone.
