The Pengfuda disc-type root shredder is a heavy-duty piece of equipment specially developed for the biomass power generation sector and large-scale material crushing applications. It can efficiently process a variety of materials, including large tree roots, large-diameter logs, used 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, this equipment has become the preferred solution for industrial-grade material crushing and processing.

Core structure of the device

The main body of the equipment consists of a frame, a housing, a power system, a hydraulic system, and an electrical system. The key working components work in synergy to ensure efficient operation of the crushing process.

• Rotating料箱: Smoothly rotates driven by a dedicated drive mechanism, providing stable support for material feeding.
• Core rotor: Driven by the rotor drive unit to rotate at high speed, it is located beneath the rotating hopper and serves as the core actuating component for material crushing.
• Optimize the feeding structure: The feed inlet and the center of the hopper adopt an offset design, paired with internal wall paddles, to create an efficient feeding mechanism that ensures uniform material loading.

Core Product Advantages

1. Anti-blocking design ensures 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, thereby addressing the root cause of material blockages and ensuring the equipment operates continuously and stably around the clock.

2. Wide range of applications, efficient crushing of multiple types of materials.

It can flexibly accommodate materials of various types and specifications: it can effortlessly crush large-diameter, heavy-duty materials such as tree roots, stumps, and old furniture, while also efficiently handling lightweight materials like baled straw, small-diameter wood, and board-offcuts and edge scraps. Feeding is convenient, and its crushing efficiency far exceeds that of conventional equipment, meeting diverse production needs.

3. Easy maintenance and significantly 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 and providing ample space for inspection and repair operations. This significantly reduces maintenance difficulty and labor input, enhances equipment operation and maintenance efficiency, and minimizes downtime.

4. Thorough crushing, with more competitive operating costs.

Adopting a multi-blade rotor cutter 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 and effectively reducing the frequency of replacement of wear parts as well as production costs, thereby creating greater economic benefits for enterprises.

5. Smart control, with comprehensively upgraded safety features.

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 enhances production efficiency but also mitigates safety risks at the operational level, fully complying with 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 under the drive of a dedicated motor. Materials are fed into the hopper via a grabber. As the hopper rotates, the internal wall’s material-feeding teeth evenly distribute the materials onto the high-speed rotating rotor. The materials are then initially crushed by the cutting and tearing action of the blades. Once crushed, the materials fall onto a screen under the influence of their own gravity and the impact force generated by the rotor. Materials that meet the required particle size specifications pass through the screen and are discharged, while those that do not meet the standards undergo secondary and tertiary crushing cycles within the crushing chamber until they finally satisfy the output criteria.
