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. Addressing this critical industry challenge, Tianhe Environmental’s integrated screening‑crushing machine offers a new, efficient, compact, and durable solution for on‑site processing at the coal‑mining face.

The Tianhe Environmental Protection Integrated Screening and Crushing Machine ingeniously combines a high‑capacity double‑tooth roll crusher with a rotary drum screen. It can seamlessly interface with transfer scraper conveyors, hydraulically self‑advancing tail units, and belt conveyors, and is installed directly at the discharge point of the face‑side transfer scraper. 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 belts 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 subsurface 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 Barre high‑wear 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, it delivers a service life of 2 to 3 years, significantly reducing downtime and maintenance costs associated with frequent component replacements.

In addition, the equipment is equipped with a large‑diameter crushing roll; this ingenious design ensures that oversized ore pieces can be fed in and fully 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 Protection 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.
