At the very source of underground coal mining, the efficiency of raw coal crushing and transportation directly impacts the overall production performance of the mine. However, the confined underground spaces and complex operating conditions often impose stringent demands on the size and performance of crushing equipment. To address this industry‑wide challenge, Tianhe Environmental has meticulously developed an integrated screening‑and‑crushing machine, offering a new, efficient, compact, and durable solution for on‑site processing at the coal‑mining face.

        Tianhe Environmental Integrated Screening and Crushing Machine It ingeniously integrates a high‑capacity double‑tooth roll crusher with a rotary trommel screen, enabling seamless connection to transfer scraper conveyors, hydraulically self‑advancing tail units, and belt conveyors, and can be directly installed at the discharge point of the face‑transfer scraper conveyor. Adhering to the scientifically sound “screen first, crush later” process, this equipment precisely classifies raw coal. This design not only significantly enhances underground raw‑coal transport efficiency and reduces transportation costs, but also effectively prevents tearing and damage to long‑distance entry‑side belt conveyors and downstream main transport belts caused by impacts from oversized material, thereby ensuring safe, continuous mine production.

Addressing the challenge of limited underground space, this integrated unit demonstrates exceptional spatial adaptability. With its compact, space‑saving design, it can be easily deployed in tight underground environments, enabling efficient on‑site processing. In terms of core wear‑resistant components, Tianhe Environmental Protection has incorporated cutting‑edge technology: both the screening drum and the crushing rollers are crafted from the company’s proprietary Bashi high‑wear‑resistant alloy. This material seamlessly combines high strength, superior toughness, and outstanding wear resistance, overcoming the industry‑standard limitations of conventional high‑manganese steel and alloy steels. Under normal operating conditions, its service life can reach 2 to 3 years, significantly reducing downtime and maintenance costs associated with frequent component replacements.

Furthermore, the equipment is equipped with a large‑diameter crusher; this ingenious design ensures that oversized ore pieces can be fed in and crushed in a single pass, effectively preventing multiple engagements and repeated crushing within the crushing chamber, thereby further enhancing operational efficiency and equipment stability.

Tianhe Environmental has consistently leveraged technological innovation to empower coal mining. This integrated screening and crushing machine is a vivid testament to Tianhe’s technical prowess and meticulous craftsmanship, helping coal enterprises reduce costs and boost efficiency at the source while steadily advancing toward a new era of green, intelligent mines.
