5–6 T/H Goat Feed Grinder in Bangladesh

Why the Feed Mill Added One Dedicated Goat Feed Grinder

The customer already had most of the equipment needed to manufacture commercial goat feed. Ingredients could be received, weighed and mixed, and an existing pelletizing section was available for the final forming stage. The weak point was size reduction. The older grinder required more interruptions when fibrous material was introduced, while inconsistent preparation made it harder to maintain a stable feed rate to the mixer and pellet mill.

Replacing only the grinder was therefore more practical than rebuilding the plant. The SFSP66×60 gives the customer a 5–6 T/H grinding section that can work with both conventional concentrate ingredients and properly preprocessed dry forage. This capacity also leaves enough margin for batch preparation without forcing the machine to run continuously throughout the entire working day.

Under the customer's normal production arrangement, the grinder can operate for approximately four effective hours during a production day. At 5–6 T/H and about 300 operating days per year, this provides a theoretical annual grinding availability of approximately 6,000–7,200 tonnes. Actual annual output depends on the proportion of fibrous ingredients, product schedule, screen selection and maintenance time.

SFSP66×60 Grinder Configuration and Capacity

The 5–6 T/H capacity is the reference range used for this project rather than the 1–1.5 T/H figure appropriate to much smaller equipment. Actual hourly throughput still depends on the raw-material mix. A batch dominated by maize or other relatively dense feed ingredients can behave differently from one containing a high proportion of low-density chopped straw or dried grass. Forage-rich batches can move toward the lower end of the operating range because fibrous material occupies more volume and creates greater feeding resistance.

Bangladesh Raw Materials Used in Goat Feed

The customer's raw-material plan reflects feed resources that are actually available in Bangladesh. Rice production generates large quantities of rice straw and rice-milling by-products, while Napier grass is cultivated as a ruminant forage. Commercial feed manufacturers can also use maize, rice bran or polish, mustard meal and other approved protein, energy and mineral ingredients according to formula requirements and market availability.

For this project, the grinder primarily handles dried Napier forage, dry rice straw and cereal ingredients requiring size reduction. Rice bran and other already fine ingredients may bypass intensive grinding when their incoming particle condition is already suitable for mixing. The objective is not to send every formula ingredient through the hammer mill regardless of physical condition.

Water hyacinth is not treated as a routine commercial ingredient in this project. Although aquatic plants can appear in feed research or local feeding practices, moisture, contamination, composition and collection conditions vary widely. A commercial goat feed mill requires a more controlled raw-material system, so the customer's main fibrous ingredients are dried forage and agricultural residues with known sourcing and preparation.

Fresh Napier Grass Cannot Go Directly into the Hammer Mill

One important distinction in this Bangladesh project is the condition of the Napier grass. Freshly harvested Napier can contain a large amount of water and long fibrous stems. Feeding it directly into an SFSP hammer mill designed for dry feed preparation would create unstable grinding, high energy consumption and material buildup around the screen.

The forage used for pellet-feed production is therefore dried to an appropriate storage and processing condition first. Baled dry forage is opened, twine and foreign material are removed, and long stems are reduced to approximately 15–40 mm through a bale breaker or coarse chopper. Only then does the prepared material enter the SFSP66×60.

Rice straw follows the same basic principle. Long straw is not pushed directly into the fine grinding chamber. It first passes through coarse preparation so the hammer mill receives a controlled material length. This staged size reduction reduces feed surges and helps the 55 kW grinder operate more consistently.

From 15–40 mm Chopped Forage to 2–5 mm Ground Material

The grinder's job is clearly defined by the material entering and leaving the machine. Dried Napier grass and rice straw arrive at the hammer mill at approximately 15–40 mm after coarse chopping. Inside the SFSP66×60, rotating hammers repeatedly impact the material until particles can pass through the selected screen.

For the fibrous portion of this goat-feed project, the customer targets approximately 2–5 mm ground material before mixing. The exact particle distribution is broader than one single number because a hammer mill does not produce perfectly identical particles. Screen aperture, hammer condition, rotor speed, forage moisture and aspiration all influence the result.

Cereal ingredients such as maize can be ground more finely, generally into an approximately 1–3 mm range where required by the formula and downstream pelletizing conditions. Different screens can therefore be installed according to the ingredient being processed instead of forcing straw and maize through one permanent setting.

This size control serves a processing function. Properly reduced ingredients mix more evenly and feed more consistently into the pelletizing system. The grinder itself does not increase nutrient content or automatically improve digestibility; those outcomes depend on the complete feed formulation, animal requirements and feeding management.

Why Long-Fiber Material Needs Controlled Feeding

Fibrous roughage creates different feeding problems from grain. Low-density chopped straw or hay can form an irregular bed above the grinding chamber, and excessively long pieces can bridge in the feeding system. Increasing motor power alone does not solve this problem if the hammer mill is receiving material inconsistently.

The customer therefore controls the upstream flow after coarse chopping and uses magnetic separation before grinding to reduce the risk from ferrous contaminants. A stable feeder meters material into the SFSP66×60 instead of allowing an entire batch of loose forage to fall into the chamber at once.

Aspiration is also important. Airflow helps move ground particles through the screen and away from the chamber while supporting dust collection. If aspiration is insufficient, fine material can remain around the screen longer than necessary, reducing practical capacity and increasing recirculation inside the grinding chamber.

This means a 5–6 T/H goat feed grinder should be evaluated as part of a feeding, grinding and air-handling section rather than as an isolated 55 kW motor.

How Grinding Connects with the Existing Mixing and Pelletizing System

After grinding, the different ingredients move to the existing batching and mixing section. Ground forage does not automatically constitute a complete goat feed. It is combined with energy ingredients, protein sources, minerals, vitamins and other components according to the feed mill's formulation.

The customer produces compound goat feed rather than simply compressing pure rice straw or pure Napier grass into pellets. Formula composition can vary according to whether the feed is intended for growing animals, breeding stock or another production stage. These nutrition decisions are handled separately from grinder selection.

The prepared mixed feed then enters the existing pelletizing system. For this project, the downstream equipment produces approximately 4–6 mm goat feed pellets according to the selected product specification. The SFSP66×60 therefore has to maintain enough grinding capacity to prevent the 5–6 T/H preparation section from becoming a bottleneck ahead of mixing and pelletizing.

If the pellet mill operates at a lower hourly rate than the grinder, ground material can be accumulated in intermediate bins and processed in scheduled batches. This is common in feed plants where grinding, mixing and pelletizing do not have identical instantaneous capacities.

Dust Control and Maintenance for Dry Forage Grinding

Dry Napier hay and rice straw generate considerably more airborne fibre and dust than many dense grain ingredients, so dust control is part of the grinding system. The customer uses enclosed conveying where practical together with aspiration and dust collection around the hammer mill. This reduces uncontrolled dust release but should not be described as creating a completely dust-free workshop.

Hammer and screen condition directly influence both capacity and output particle distribution. As hammer edges wear, impact efficiency decreases and more material can circulate inside the chamber before passing through the screen. A worn or damaged screen can also change the particle profile entering the mixer.

The customer therefore inspects hammers, screens, fasteners, bearings and rotor condition according to actual operating hours and feedstock condition. There is no fixed wear-life promise because clean maize and dusty field-collected rice straw can produce very different wear rates. Soil and sand contamination in straw are particularly important because abrasive mineral material accelerates component wear.

Why the 5–6 T/H Capacity Fits This Bangladesh Feed Mill

The selected capacity fits a medium feed operation better than the 1–1.5 T/H figure initially associated with this machine. At 5–6 T/H, four effective grinding hours per production day provide approximately 20–24 tonnes of ingredient preparation capacity. Across 300 operating days, this corresponds to about 6,000–7,200 tonnes of theoretical annual grinding availability.

This does not mean the company must manufacture 7,200 tonnes of finished goat pellets every year. Some ingredients may bypass grinding, the grinder may support different formula batches, and planned downtime must be considered. The annual figure describes the available grinding capacity under the stated operating schedule rather than a claimed sales result.

The customer also retains flexibility to extend grinding hours if demand increases. Before increasing annual output, however, the mill needs to confirm that upstream coarse chopping, batching, mixing, pelletizing, cooling and packaging equipment can all accept the additional production load.

Shipping the Goat Feed Grinder to Bangladesh

The SFSP66×60 Goat Feed Grinder in Bangladesh was prepared for export from Qingdao, China, with Chattogram used as the destination seaport before inland delivery toward the Dhaka-area feed mill. The route matches the customer's location and Bangladesh's main international machinery import channel.

Before shipment, RICHI reviews the grinder installation position, motor and electrical requirements, inlet and outlet elevation, existing feeder, aspiration connection and downstream conveying arrangement. This interface work matters because the machine is being inserted into equipment already operating at the customer's plant rather than being installed inside a completely new RICHI animal feed production line.

The customer therefore retains its existing mixer and pelletizing equipment while the SFSP66×60 replaces the weak point in ingredient preparation.

What to Confirm Before Selecting a Goat Feed Grinder

• Required capacity: This project uses an explicit grinding range of 5–6 T/H.
• Forage condition: Fresh Napier is not fed directly; dry forage is opened and coarsely chopped first.
• Input size: Dry Napier and rice straw are approximately 15–40 mm before fine grinding.
• Output size: Ground fibrous material is targeted at approximately 2–5 mm, while grain can be approximately 1–3 mm depending on the formula.
• Moisture: Feedstock must be sufficiently dry for stable hammer-mill operation and storage.
• Raw-material mix: Maize, rice by-products, mustard meal and forage create different grinding loads.
• Existing equipment: Bale breaking, chopping, mixing, pelletizing and dust collection should be checked before the grinder is integrated.

A 5–6 T/H Goat Feed Grinder in Bangladesh

This Goat Feed Grinder in Bangladesh project uses one RICHI SFSP66×60 with a 55 kW main motor to upgrade the ingredient-preparation section of an existing compound feed mill near Dhaka. The machine provides a clear reference grinding capacity of approximately 5–6 T/H for suitable prepared feed materials, with a theoretical annual grinding availability of approximately 6,000–7,200 tonnes under the customer's four-hour-per-day, 300-day operating arrangement.

Long fibrous materials are prepared before they reach the hammer mill. Dried Napier grass and rice straw are opened and chopped to approximately 15–40 mm, then reduced through the SFSP66×60 to an approximately 2–5 mm target range. Grain ingredients can be ground to approximately 1–3 mm where required. The prepared ingredients then enter the customer's existing batching, mixing and pelletizing system for production of approximately 4–6 mm compound goat feed pellets.

For another feed mill evaluating a goat feed grinder, RICHI Machinery needs the raw-material list, percentage of forage versus grain, fresh or dry material condition, bale type, chopped feed size, required ground particle range, required T/H, operating hours, existing bale breaker or chopper, mixer machine capacity, feed pellet machine capacity and dust-control arrangement. These parameters determine whether the SFSP66×60 is correctly matched to the plant or whether another grinding configuration is required.
