The Pengfuda disc-type root shredder is a heavy-duty machine specially developed for biomass power generation and large-scale material crushing applications. It can efficiently process a variety of materials, including large tree roots, large-diameter logs, formwork, bark boards, branches, and straw. The core model series includes the 3300 and 3600 series. With its precise structural design, advanced technological features, and stable operational performance, it has become the preferred solution for industrial-grade material crushing and processing.

Core structure of the device

The equipment features a modular design. Its main components include a frame, a housing, a power system, a hydraulic system, and an electrical system. The key working parts work in synergy to ensure high crushing efficiency.

• Rotating料箱: Driven by a dedicated drive mechanism, it rotates to provide a stable feeding and pre-processing environment for the materials.
• Core rotor: Mounted beneath the rotating hopper, it achieves high-speed rotation via a rotor drive mechanism and serves as the core actuating component for material crushing.
• Optimize the feeding structure: The feed inlet is offset from the center of the hopper, and when paired with integrated feeding teeth on the inner wall, this creates a highly efficient and coordinated feeding mechanism that enhances the smoothness of material loading.

Core Product Advantages

1. Anti-blocking design for continuous, uninterrupted operation

The innovative design incorporates a combined structure featuring an offset feed inlet and internal wall paddles, enabling auxiliary feeding functionality. Paired with advanced variable-frequency control technology: when the rotor load exceeds the set threshold, the feed hopper automatically reverses its rotation, addressing the root cause of material blockages and ensuring the equipment operates continuously and stably around the clock, thereby preventing production interruptions.

2. Wide range of applicability and highly efficient compatibility with multiple materials.

Flexibly meets crushing needs across all scenarios: It can handle large-diameter materials such as tree roots, stumps, and discarded furniture, as well as lightweight materials like baled straw, small-diameter wood, and board-offcuts and edge scraps. With convenient feeding and highly efficient crushing, it provides a one-stop solution to meet the material-processing requirements of various industries.

3. Convenient maintenance and reduced labor costs

Equipped with a hydraulically operated hopper-turning device, this system allows for large-angle tipping during maintenance and servicing, fully exposing the rotor’s core components. This significantly simplifies the inspection and maintenance process, reduces labor requirements, and lowers equipment operation and maintenance costs.

4. Thorough crushing with controllable operating costs.

Adopting a multi-blade rotor knife roll design ensures more uniform and thorough material crushing. The blades are scientifically arranged and made from high-quality, wear-resistant materials, significantly extending their service life, effectively reducing the frequency of replacement of wear parts, and helping to control overall production costs for enterprises.

5. Automated control with a high safety factor

All electrical components of the machine are integrated and controlled automatically, supporting wireless remote control for remote operation, thereby reducing on-site manual intervention. This not only boosts production efficiency but also ensures personnel safety from the very source of operation, meeting modern industrial safety production standards.

Working principle

After the disc-type root crusher is started, the motor drives the rotor to rotate at high speed, while the feeding hopper rotates slowly in synchronization. The material is fed into the hopper via a grabber. As the rotor spins, the internal wall’s feeding teeth evenly distribute the material onto the high-speed rotating rotor, where it undergoes preliminary crushing through cutting and tearing action by the blades. The crushed material then falls onto a screen inside the crushing chamber under the combined effects of its own gravity and the rotor’s impact force. Material meeting the required particle size specifications passes through the screen and is discharged, while material that does not meet the standards continues to be subjected to secondary and tertiary crushing within the chamber until it finally satisfies the output criteria.
