In industrial and mining production, efficient crushing of minerals is crucial for enhancing resource utilization and reducing production costs. Traditional impact-type crushing equipment often suffers from severe over-crushing, uneven particle size distribution, and frequent blockages—issues that not only impair resource efficiency but also impose additional burdens on downstream processes.

How can we achieve "accurate breaking, stable screening, and long-lasting use"? Tianhe Environmental Protection has introduced Double-tooth roll crusher Based on the core crushing principles of shearing and compression, this approach offers a more targeted solution for these complex materials.

Precise crushing, resulting in a higher block yield.

The Tianhe Environmental Protection Double-Tooth Roll Crusher utilizes two counter-rotating rollers to achieve material separation through shearing, compression, and tensile forces. This "slow-pressure" crushing method effectively controls the crushing intensity, significantly reducing the generation of fine powder while enhancing the rate of lump formation. It is particularly well-suited for applications such as coal processing—where strict requirements are placed on particle shape and size stability—as well as scenarios like quicklime calcination and calcium carbide production.

Structurally reliable, suitable for sticky and moist materials

For materials prone to sticking and clogging—such as clay, oil shale, and water-containing construction waste—the equipment features an optimized tooth arrangement and roller surface gap, complemented by a spiral tooth layout that enhances the material’s self-cleaning capability and reduces the risk of blockages. Additionally, the crushing teeth are available in three optional designs: movable-tooth type, collet-type, or solid-roller type, making them easy to replace and maintain while effectively meeting the demands of various operating conditions.

Wear-resistant and durable, operating more economically.

The broken teeth are made from a bainitic wear-resistant alloy (HRC45-55), offering an impact toughness of up to 38 kg·m/cm², ensuring a longer service life compared to conventional products. The split-box structure, combined with a multi-layered sealing design, effectively prevents dust and moisture from infiltrating the bearing system, thereby enhancing the equipment's long-term operational reliability and reducing maintenance costs.

Smart integration, making the system more efficient.

The double-tooth roll crusher can be flexibly integrated into either a stationary screening and crushing line or a mobile crushing station, working seamlessly with the heavy-duty apron feeder, vibrating screen, and PLC control system to ensure stable operation throughout the entire process—from feeding to finished product output. It offers convenient operation while maintaining continuous production.

In today’s world, where efficient resource utilization and green production are becoming increasingly vital, crushing is no longer just about "breaking things apart"—it’s now about "precise control." Tianhe Environmental’s dual-tooth roller crusher, backed by a deep understanding of material properties and robust engineering design, helps companies achieve more stable and sustainable mineral processing even under challenging operational conditions.
