The WRBB Series Horizontal Bagging Baler is engineered for compressing and bagging small-particle loose materials — including sawdust, wood shavings, wood chips, rice husks, rags, cotton fibers, and similar loose waste. Controlled by a PLC system with single-button operation, the machine automatically completes the full cycle of compression, bale ejection, and bagging with a cycle time as fast as 16 seconds. The result is a uniformly sized, bagged bale that is ready for storage, transport, or resale as a recycled material. The WRBB Series is available in three models: WRBB-400, WRBB-600, and WRBB-800.

What Is a Horizontal Bagging Baler?

Horizontal Bagging Baler: A hydraulic machine that compresses loose, low-density solid waste horizontally inside a compression chamber, then automatically ejects and bags the compacted bale into a plastic bag. Unlike vertical balers, the horizontal design allows for continuous material feeding and is well-suited for high-throughput production environments.

The WRBB Series is purpose-built for facilities that generate large volumes of loose waste — pet food factories, animal bedding manufacturers, textile recycling plants, fertilizer factories, farms, and any industrial operation where uncompressed loose material creates storage or logistics challenges. Compressing these materials into consistent bagged bales reduces volume significantly and increases the commercial value of the output as a reusable resource.

Key Features

The WRBB Series is designed around two operational priorities: minimizing manual labor and enabling continuous, uninterrupted baling output.

• PLC Automatic Control: A stored-program controller automates the full sequence of compression, bale ejection, and bagging. The system runs consistently across extended shifts without operator intervention.
• Single-Button Operation: The entire compression and ejection cycle is initiated with one button. Minimal technical training is required, making it straightforward to integrate into existing production workflows.
• Electric Control System: Platen movement and bale ejection are controlled electronically via switches, providing precise, repeatable actuation with low maintenance requirements.
• Optional Automatic Feeding Conveyor: When connected, the conveyor automatically starts and stops based on hopper material level, enabling continuous feeding and maximizing throughput without additional labor.
• Optional Horizontal Cutter on Feed Aperture: For long-fiber materials such as rags and textile scraps, an optional horizontal cutter at the feed opening cuts material before it enters the compression chamber, preventing jamming and ensuring uninterrupted operation.

The WRBB Series Horizontal Bagging Baler is built for demanding industrial environments. The heavy-duty steel frame and teal-finished enclosure house a fully integrated hydraulic system, with the power unit and PLC control panel positioned for easy access during operation and routine maintenance. The optional automatic feeding conveyor — shown in the upper right — feeds material directly into the compression chamber at a controlled rate, eliminating manual loading and enabling continuous production. The close-up of the hydraulic cylinder assembly illustrates the precision-engineered components that deliver consistent compression force across every baling cycle.

Every cycle of the WRBB Series produces a firmly compressed, uniformly sized bale ready for immediate handling, storage, or shipment. The wrapped cotton fiber bale (upper left) and wood shaving bale (upper right) demonstrate the machine’s output across different material types — both compact, dense, and easy to palletize. The lower images show the ejection sequence in action: a wood shaving bale sliding off the ejection platform, and the finished plastic-bagged output standing upright beside the machine. The consistent bale dimensions across all material types simplify downstream logistics and make the output directly suitable for resale as animal bedding, biomass fuel, or recycled fiber.

Applicable Materials

Applicable Material Definition: The WRBB Series is designed for small-particle, low-density loose solids. These materials are difficult to store or transport in uncompressed form due to high bulk volume. After hydraulic compression and bagging, the output bales have a consistent shape and weight, reducing storage footprint and improving logistics efficiency.

The WRBB Series has been applied to the following material types:

• Wood-based: sawdust, wood shavings, wood chips, wood offcuts
• Agricultural: rice husks, straw, peanut shells, cottonseed hulls, rice bran
• Fiber-based: rags, cotton fibers, mineral cotton fibers
• Other: paper shreds, cottonseed meal, and similar loose materials

Industries served include pet food production, animal bedding facilities, textile recycling operations, fertilizer manufacturing, farms, and general manufacturing plants producing high volumes of loose process waste.

Frequently Asked Questions

What materials can the WRBB Series process?

The WRBB Series is designed for small-particle, low-density loose materials including sawdust, wood shavings, wood chips, rice husks, straw, rags, cotton fibers, paper shreds, and similar loose waste. For long-fiber materials such as rags or textile scraps, the optional horizontal feed cutter attachment is recommended to prevent jamming at the feed aperture.

Can the WRBB Series support fully automatic, continuous operation?

Yes. With the optional automatic feeding conveyor, the WRBB Series operates continuously without manual feeding intervention. The conveyor automatically starts and stops based on hopper material level, working in coordination with the PLC control system to maintain consistent output throughout an entire production shift.

What is the difference between the WRBB-400, WRBB-600, and WRBB-800?

The three models differ primarily in compression force and bale output weight. The WRBB-400 operates at a platen pressure of 26.5 kgf/cm² and produces bales of approximately 20–25 kg (wood shavings). The WRBB-600 increases platen pressure to 30.1 kgf/cm², yielding denser bales at 25–30 kg. The WRBB-800 delivers the highest compression at up to 47.1 kgf/cm², with sawdust bales reaching 35–60 kg per cycle — suited for large-volume facilities where heavier bales reduce handling frequency and transport costs.

What routine maintenance does the WRBB Series require?

Standard maintenance includes periodic inspection and replacement of hydraulic fluid, inspection of hydraulic cylinder seals, and — where the optional feed cutter is installed — checking blade wear and scheduling replacement as needed. A detailed maintenance schedule is provided in the equipment manual. Our after-sales engineering team is available to develop a maintenance plan based on your actual operating hours and shift patterns.

Is the bale size fixed, or can it be customized?

Standard bale dimensions for each model are listed in the specification table above. If your packaging or downstream logistics require a non-standard bale size, please raise this during the inquiry stage so our engineering team can assess technical feasibility for your application.
