Double Teeth Roller Crusher

Product Introduction

Meet the Double Teeth Roller Crusher, the definitive force for precision and resilience in primary and secondary size reduction. Engineered for the relentless demands of mineral processing, quarrying, and aggregate production, this crusher transforms challenging, bulky feed material into a controlled, consistent product. Its foundation is a massively constructed frame housing two synchronized, high-integrity rotors fitted with proprietary intermeshing teeth. This intelligent design delivers a powerful shearing and crushing action, prioritizing clean fragmentation over random impact to protect material integrity and maximize yield of the desired product fraction. Beyond raw power, it is built for seamless integration into continuous operation circuits, offering unmatched reliability that keeps critical processes flowing.

Key Advantages

1. Selective Crushing Action: Proprietary interlocking tooth geometry applies a combined shearing and splitting force, ensuring efficient size reduction while actively minimizing the generation of excessive, undesirable fines.
2. Uncompromising Structural Integrity: Fabricated from heavy-duty plate and featuring high-strength, alloy-steel shafts and rotors, the crusher is built to absorb shock loads and withstand the most abrasive materials, guaranteeing extended service life.
3. Operational Flexibility: Adjustable mounting and drive configurations allow for optimization of product sizing and throughput, making it a versatile solution for both coarse and medium crushing stages within a single, robust unit.
4. Rapid Maintenance & Serviceability: A forward-thinking design incorporates fully replaceable tooth segments and easy-access covers. This enables swift wear part replacement, dramatically reducing downtime and maintenance costs.
5. Drivetrain Confidence: Powered by a high-torque motor through a safeguarded coupling and industrial-grade gear reducer, the system delivers dependable power transmission. Protected, grease-lubricated bearing assemblies ensure smooth, sustained operation.
6. Streamlined Material Flow: The optimized chamber and tooth profile promote steady material intake and discharge, preventing choke points and promoting overall system throughput efficiency without compromising fragmentation control.

Frequently Asked Questions (FAQ)

Q: What types of material is this crusher best suited for?

A: It excels in processing raw coal, limestone, shale, gypsum, friable minerals, and overburden in open-cast mining. It is ideal for materials where controlled fragmentation with reduced fines is critical.

Q: How does the design help reduce maintenance downtime?

A: Key wear components like the crushing teeth are modular and fully replaceable without major disassembly. Combined with easy-access inspection points, this allows for rapid servicing to maximize operational uptime.

Q: What makes it different from a standard impact crusher?

A: Unlike impact crushing which uses high-speed collision, the double-tooth roller design employs a controlled shearing and compression action. This provides more predictable product sizing and significantly lower generation of fine particles.

Q: Is the product size adjustable?

A: Yes, through adjustable settings and optional configurations, the gap between the rotating rollers can be managed to influence the final product top-size, offering valuable processing flexibility.

Q: How is long-term bearing protection ensured?

A: The crusher utilizes sealed, grease-lubricated bearing housings, often compatible with automated lubrication systems. This design provides a reliable barrier against contamination and ensures consistent protection with minimal manual intervention.
