Double Tooth Roller Crusher
Q1: Why is the toothed roller better for sticky or high-moisture materials?
Traditional smooth rollers often suffer from “slipping” or material buildup when handling wet clay or coal. The APEX tooth structure combines extrusion, shear, and splitting. The serrated teeth grip the material firmly and break it apart, while the self-cleaning design naturally prevents adhesion and “bridging” issues in the chamber.
Q2: Can the tooth shape be customized for specific material hardness?
Absolutely. One of the core strengths of APEX is flexibility. We can fully customize the shape, length, and density of the teeth based on your specific material type (e.g., coal, bauxite, or limestone) and desired discharge size to maximize crushing efficiency and minimize wear.
Q3: How does the hydraulic system protect the machine from tramp iron?
Our crushers feature an Automatic Hydraulic Overload Protection System. If an unbreakable object like an iron block enters the machine, the movable roller instantly retracts to clear the obstacle and then resets automatically. This prevents damage to the shafts and motors, ensuring maximum uptime.
Q4: What is the expected lifespan of the toothed rolls?
APEX toothed rolls are constructed from a high-chromium manganese steel alloy. This specialized material offers a service life 3-5 times longer than standard rolls. Additionally, our modular tooth design allows for quick replacement of individual segments, drastically reducing maintenance time.
Q5: Is this crusher suitable for urban construction waste recycling?
Yes. It is widely used for crushing limestone, shale, and concrete aggregates. The shear-crushing process produces dense, cubic-shaped particles with low needle-flake content, making it an excellent choice for producing high-quality recycled aggregate for road bases and foundations.
