In the vast realm of mineral processing, crushing equipment serves as the “bottleneck” of industrial production, with its performance directly determining the efficiency and profitability of the entire production line. Addressing longstanding industry challenges—such as unstable bearing alignment, shaft misalignment and axial movement, and short service life—Tangshan Tianhe Environmental Protection Technology Co., Ltd., drawing on more than two decades of technological expertise, has introduced an innovative dual‑tooth roller classifying crusher, offering a reliable, cutting‑edge solution for sectors like coal and power generation.

          Tianhe Environmental Protection 2DSKP/2PLF Series Grading Crusher It is a meticulously crafted machine specially designed to meet the demanding and challenging operating conditions prevalent in China. The equipment features an integral box‑type crushing chamber, which fundamentally addresses the issues of unstable bearing positioning and shaft misalignment or axial movement inherent in split‑box designs. Moreover, its highly sealed crushing chamber effectively ensures a clean working environment.

In terms of core components, Tianhe Environmental Protection demonstrates robust technical strength. Its crushing teeth are crafted from a proprietary bainitic wear‑resistant alloy, achieving a hardness of HRC 45–55 and an impact toughness of 38 kg·m/cm². This material combines exceptional hardness, superior wear resistance, high toughness, and excellent impact resistance, delivering a service life two to three times that of standard industry products. The crushing‑tooth designs are highly diversified, encompassing split‑tooth, sleeve‑type, tooth‑ring, tooth‑plate, and full‑roller configurations, enabling tailored solutions and optimized component selection to create cost‑effective equipment.

The arrangement of the crushing teeth on the equipment is equally flexible and versatile, offering various configurations—including single‑helix, double‑helix, multi‑helix, staggered, and straight‑line designs—to ensure a high lump‑breakage rate and excellent crushing efficiency. Product particle size can be precisely adjusted via three methods—eccentric cups, lead screws, and hydraulics—meeting the demands of diverse operating conditions. Couplings, pulleys, and even certain toothed rollers are designed for quick disassembly and reassembly, providing adequate strength while significantly enhancing maintenance convenience.

In terms of intelligence, the equipment is equipped with advanced overload and stall protection devices, as well as intelligent control and lubrication systems, ensuring convenient operation and safe, reliable performance. A variety of undercarriage options are available, facilitating equipment inspection and maintenance, significantly enhancing the crusher’s operational reliability and reducing potential failure points during operation.

Tianhe Environmental’s double‑tooth roller classifier crusher is widely used in the coal industry for crushing raw coal, washed clean coal, lignite, and gangue, as well as in the power sector for crushing boiler‑firing coal. It is suitable for a variety of settings, including underground mines, coal preparation plants, and open‑pit crushing stations. Covering applications from coarse to fine crushing, Tianhe Environmental offers a full range of specifications, driving product upgrades through technological innovation and helping enterprises advance steadily on the path of green, efficient development.
