In fields such as coal washing and beneficiation, limestone powder production, and construction aggregate processing, precisely controlling the particle size of the discharged material while maintaining high throughput and minimizing fine-particle generation has always been a key focus of process optimization.

For Mohs hardness For brittle materials below Grade 5—such as raw coal, coke, limestone, shale, and the like—although traditional hammer crushers or impact crushers are highly efficient, they tend to cause over-crushing, which can negatively affect the efficiency of subsequent calcination, screening, or combustion processes.

At this moment, with The double-tooth roller crusher, which operates on the principle of “low-speed compression plus shear,” demonstrates unique value. The Tianhe Environmental Protection double-tooth roller crusher is precisely the high-efficiency solution tailored for this type of brittle and hard material.

The double-tooth roll crusher applies shear, tensile, and compressive forces to the material by means of a controllable gap, achieving “precise liberation” that effectively inhibits over-crushing and significantly increases the proportion of lump-shaped finished products. The particle size of the discharged material is determined by the gap between the rolls and can be adjusted flexibly, making it particularly suitable for applications such as lump coal for boilers, limestone for calcium carbide production, roadbase aggregates, and other scenarios with specific requirements for particle shape and size.

The Tianhe Environmental Protection double-tooth roller crusher features a high-strength, monolithic box-type structure. The roller shafts have undergone precise dynamic balancing, ensuring smooth operation. The equipment’s tooth profile layout has been optimized. — Optional tooth arrangements include single-spiral and double-spiral designs, and the structure supports movable-tooth, clamp-type, or solid-roller configurations for easy cleaning and replacement.

The broken teeth are made of a high-toughness, wear-resistant alloy. HRC45-55), with an impact toughness of 38 kg·m/cm², balancing service life and impact resistance. The all-in-one box-type structure, combined with a multi-layer sealing design, effectively prevents dust and moisture from entering the bearing system, ensuring long-term stable operation. 。

The double-tooth roll crusher can be used either independently or integrated into fixed or mobile screening and crushing systems. It works in synergy with vibrating feeders, heavy-duty apron feeders, and screening equipment to form an efficient closed-loop process. The PLC control system supports operation monitoring and safety protection, ensuring continuous and stable production.

In today’s pursuit of efficient resource utilization and refined processes, crushing is no longer... “It’s not about breaking it into smaller and smaller pieces—it’s about breaking it just right.” The Tianhe Environmental Protection Double-Tooth Roll Crusher, with its profound understanding of the properties of brittle and hard materials, helps users achieve higher-quality, lower-loss, and more sustainable processing goals.
