Chicken Feed Granule Breaker in Oman | RICHI SSLG15*120

Why the Feed Mill Needed a Separate Crumbling Machine

The customer is a medium-sized commercial poultry feed manufacturer serving broiler farms in Oman. Its existing production operation includes the normal stages of ingredient preparation, grinding, batching, mixing, conditioning and pellet production. The immediate limitation is not a shortage of pelleting capacity. It is the lack of a convenient way to turn selected finished pellets into smaller feed particles.

Broiler feed specifications change as birds grow. Larger birds can generally consume conventional pellets, while younger birds may benefit from a smaller, more manageable feed form. A feed mill that supplies different farm sizes and production schedules may therefore need both standard pellets and crumbled feed. Producing only one physical format can limit its flexibility when customers request different grades.

Oman's poultry sector includes commercial broiler production as well as businesses involved in feed supply and poultry integration. Local operating conditions also make practical feed management important: high ambient temperatures, feed storage conditions and the distance between production facilities and farms can influence how feed is handled. For a manufacturer serving several customers, adding a smaller feed grade can be more practical than rebuilding the existing process around a new line.

The purchase was therefore focused on one piece of equipment. The SSLG15*120 is intended to handle only the batches that need crumbling. Standard pellets can continue through the existing packing route, while selected batches are directed to the additional machine. This keeps the project focused on a specific production gap rather than adding unnecessary equipment to a functioning plant.

Selected Model and Main Technical Parameters

RICHI's SSLG15*120 double-roll crumbler was selected for the assumed scale of this application. It has a 5.5 kW drive, two crumbling rolls with a diameter of 15 cm and a roll length of 120 cm. Compared with the smaller SSLG15*50 and SSLG15*80 models, the longer roll provides a different working configuration for a feed mill that needs to process selected batches rather than operate a very small pilot unit.

The model choice is based on the intended product and the customer's requirement for an additional crumbling stage. The supplied model specifications do not state a rated hourly capacity for the SSLG15*120, so a firm throughput figure should not be assumed. Actual output will depend on pellet diameter, hardness, moisture, formula characteristics, roll settings and the acceptable proportion of finished crumbles.

Before finalizing the installation, the factory should provide representative feed samples and confirm the required particle-size distribution. This allows the equipment configuration and operating procedure to be checked against the real material instead of relying solely on nominal pellet dimensions.

What Goes Through the Chicken Feed Granule Breaker?

The incoming material is finished broiler feed pellets made from a balanced formula selected by the customer's nutrition team. Depending on the feeding program and ingredient availability, the formula may contain maize, soybean meal, wheat or other suitable cereal ingredients, vegetable oil, limestone, phosphate sources, salt, vitamin and mineral premixes, and other feed additives. The exact proportions are not fixed by the crumbler and should follow the manufacturer's formulation and nutritional specifications.

For this project, the incoming pellet size is assumed to be around 3–4 mm. The double-roll crumbler reduces the pellets to smaller fragments, with a target finished size of approximately 1.5–3 mm. These figures are proposed operating targets for the case, not a guarantee that every fragment will fall within the stated range.

The distinction between pellet production and crumbling is important. The pellet mill forms the feed into compact cylindrical pellets. The crumbler then breaks selected pellets into smaller pieces. It does not replace grinding of raw ingredients, mixing of the formula or the conditioning process required before pelleting.

The physical properties of the original pellets affect the final result. Pellets that are too hard may require different operating adjustments from those that fracture easily. Moisture, binding characteristics and formula composition can also influence the proportion of acceptable crumbles and the amount of fine material produced. The factory should therefore evaluate the actual feed before fixing its standard operating settings.

Matching Crumble Size to Broiler Growth Stages

The purpose of the new machine is to provide a feed format suitable for selected young-broiler feeding programs. Smaller crumbles can be easier for young birds to pick up than larger pellets, depending on bird age, body size, feeding equipment and management conditions. A target range of approximately 1.5–3 mm gives the manufacturer a starting specification for its proposed product grade.

The exact feed size should not be treated as a universal recommendation for every broiler farm. Starter-feed requirements vary with the production program and the physical quality of the finished product. The customer's technical team should confirm the final specification with its nutritionist and farm customers before the new crumble grade is marketed.

Consistent particle size matters commercially. Excessively large fragments may not meet the intended starter-feed specification, while an excessive amount of fines can create handling difficulties and lead to uneven feed distribution. The crumbler must therefore be assessed not only by the total quantity processed, but also by the proportion of material that meets the customer's quality requirements.

The new unit gives the factory more control over product presentation. It can continue producing regular pellets for older broilers and process selected batches into crumbles for younger birds. This separation also helps production staff avoid unnecessary crumbling of feed that already meets the customer's required specification.

How the Double-Roll Design Fits This Application

The SSLG15*120 belongs to RICHI's double-roll crumbler range for ordinary livestock and poultry feed. Its design is comparatively straightforward: pellets enter the working area and pass between two rolls that break them into smaller pieces. The machine is intended to provide a practical way of producing crumbled feed without adding a complicated processing stage.

The roll configuration is relevant to this project because the factory is processing finished pellets rather than grinding whole grains or raw protein ingredients. The purpose is controlled breakage, not fine powder production. The roll gap and operating conditions should be adjusted to balance the required crumble size against excessive fines and unwanted large fragments.

For a medium-sized feed mill, the 5.5 kW SSLG15*120 offers a defined equipment option for a dedicated crumbling task. The actual production rate must be confirmed under the customer's operating conditions. The factory should also review the available installation space, the feeding arrangement, the discharge height and the maintenance access needed around the machine.

RICHI's double-roll and three-roll crumblers serve different applications within the wider product range. Standard double-roll models are intended for conventional livestock and poultry feed, while the X-type three-roll configurations are designed specifically for shrimp feed and use finer crumbling teeth. Since this project concerns ordinary chicken feed, the SSLG15*120 double-roll model is the relevant configuration.

Adding One Machine to an Existing Production Line

The customer does not need to replace its feed pellet machine to introduce the new crumble product. The existing line remains responsible for ingredient handling, grinding, batching, mixing, conditioning and pellet formation. The crumbler is installed as an additional downstream machine and used only for selected batches.

Depending on the plant layout, finished pellets can be transferred to the crumbler by a suitable conveyor or feeding arrangement. The discharge can then be directed to the appropriate screening, conveying or packing stage. These connections must be designed around the actual building and equipment arrangement rather than assumed from the model name alone.

Screening may be useful when the product specification requires a controlled size range. The crumbler can produce a mixture of smaller crumbles, larger fragments and fines, so a screening stage may be needed to separate the target fraction. Oversized material may be suitable for reprocessing, subject to the factory's product-quality and feed-safety procedures.

Before installation, the customer should confirm the electrical supply, equipment foundation or support structure, material flow, dust management, inspection access and cleaning arrangements. These checks are especially important when adding equipment to a plant that already has an established production schedule.

This incremental approach helps the manufacturer test market demand for crumbled broiler feed without committing to a complete new line. If the product gains acceptance, production planning can be adjusted around the new machine. If demand remains limited, the equipment can continue to serve selected batches rather than becoming an unnecessary step in every production run.

Quality Checks That Determine the Finished Product

The finished crumble should be evaluated against a defined particle-size specification. The nominal target of 1.5–3 mm is only the starting point; the factory should also establish the acceptable percentage of material within that range, the maximum permitted oversize fraction and the limit for excessive fines.

During commissioning, samples should be taken from the discharge and checked using suitable sieves. The results can show whether the chosen settings are producing the intended grade and whether further adjustment or screening is necessary. The factory should record the test results so that future batches can be produced more consistently.

It is useful to distinguish total throughput from acceptable finished-product output. A batch may pass through the crumbler without interruption but still require screening or reprocessing before it meets the product specification. Measuring both quantities provides a more meaningful picture of the machine's performance.

Durability should also be checked. The process of breaking pellets changes their exposed surface area and can affect the way the particles behave during handling and feeding. The factory should assess the finished crumble for fines generation, storage stability and suitability for the intended feeding equipment.

Maintenance and Routine Operation

Regular inspection of the rolls, drive components, feeding arrangement and discharge area helps maintain stable operation. A change in the crumble-size distribution, unusual noise or abnormal vibration may indicate that the machine needs adjustment or inspection. Maintenance intervals should follow the manufacturer's instructions and the actual operating conditions.

Cleaning is also important when the factory handles multiple feed formulas. Residual material should be managed according to the plant's feed safety and product-changeover procedures. The machine should be positioned so that operators can access the relevant inspection points without obstructing adjacent equipment.

Wear-part life will depend on operating hours, feed characteristics, roll condition and maintenance practices. Rather than assuming a fixed replacement interval, the factory should monitor the condition of the working surfaces and document changes in product quality over time.

Why RICHI Was Considered for the Upgrade

For this project, the main selection criteria are the machine's suitability for conventional poultry feed crumbling, its straightforward operating principle and its ability to be added to an existing chicken feed production line. The SSLG15*120 provides a specific configuration for the intended application without requiring the customer to replace its established pellet-production equipment.

Technical support is particularly valuable when a single machine is integrated into an existing plant. Before dispatch, the model, electrical requirements, feeding and discharge connections, installation dimensions and maintenance access should be reviewed. The customer can also provide representative pellets and its required crumble specification so that the application can be assessed before the equipment is put into regular service.

During commissioning, the factory should record particle-size distribution, acceptable-product yield, fines generation and the adjustments needed to achieve a repeatable result. These observations help establish an operating procedure for the production team and provide a factual basis for evaluating the investment.

For other feed manufacturers considering a similar upgrade, useful information to prepare includes the current pellet diameter, the target crumble size, the required production schedule and the available installation space. These details help RICHI Machinery assess the application and recommend a suitable model rather than selecting equipment on power rating alone.

Shipment to Oman

The planned sea shipment is from Qingdao Port in China to Sohar Port in Oman. Sohar is a major commercial port serving the country's import and industrial logistics needs. The final shipping schedule and cargo arrangement should be confirmed according to the machine's packing dimensions and the freight forwarder's booking.

Before dispatch, the receiving site should confirm unloading access, the installation area and the required electrical connections. The factory should also prepare the intended material-flow route so that the crumbler can be connected to the existing production process without avoidable installation delays.

Equipment documentation and installation information should be reviewed before the machine arrives. Preparing these details in advance helps the customer organize the installation and plan the initial operating tests.

Customer Feedback and Project Acceptance

The main acceptance question for this project is whether the new crumbler can produce the intended broiler-feed crumble grade without disrupting conventional pellet production. The customer should evaluate the finished particle distribution, the amount of fines, the proportion of acceptable crumbles and the ease of switching between product batches.

The production team should also assess the practical benefits of adding a standalone machine. If selected batches can be processed without changing the main feed pellet mill settings or rebuilding the line, the factory gains a more flexible way to supply different feed formats. The commercial value will ultimately depend on the quality of the finished product, actual operating performance and demand from poultry customers.

Any direct testimonial or statement attributed to the customer should be based on feedback actually collected after installation. For this case, acceptance is best documented through measured operating results and the customer's confirmed evaluation rather than an invented quotation.

A Targeted Investment in Chicken Feed Crumbling

The chicken feed granule breaker in Oman project is designed around a defined production requirement: adding a smaller crumble-feed option without purchasing a complete new poultry feed production line. One RICHI SSLG15*120 double-roll crumbler is selected to process finished broiler feed pellets measuring approximately 3–4 mm into a target crumble size of around 1.5–3 mm.

The selected machine has a 5.5 kW drive, two rolls measuring 15 cm in diameter and 120 cm in length. Its final operating performance must be verified using the customer's actual pellets, with particular attention to the acceptable crumble fraction, oversize material and fines generation.

The value of the investment lies in adding a dedicated processing step to equipment the factory already owns. For poultry feed manufacturers planning a similar upgrade, RICHI Machinery can review the feed specifications, confirm the machine configuration and help prepare the installation plan. Providing the incoming pellet size, required crumble range and expected operating schedule is a practical first step toward selecting equipment that fits the factory's real production needs.
