Global Project Case

300TPH Raw Coal Crushing Solution: Eliminating Clogging in Wet Environments

A heavy-duty tooth roller application designed for sticky and high-moisture material processing.

1. Project Background

Double Tooth Roller Crusher

A large-scale coal preparation plant in Central Asia struggled with extreme material adhesion during the rainy season. Their existing impact crushers frequently suffered from “blind holes” and material bridging when processing raw coal with a moisture content exceeding 15%. This resulted in frequent production stoppages, high manual cleaning costs, and inconsistent discharge particle sizes, severely impacting the efficiency of the downstream coking process.

2. The HSM Solution

To solve the clogging nightmare and ensure 24/7 stable operation, HSM engineers deployed the 2PGC1200×1500 Hydraulic Double Toothed Roller Crusher:

Self-Cleaning Teeth: Our Double Tooth Roller Crusher features a unique tooth geometry that shears and splits materials, naturally preventing sticky coal and mud from building up on the roller surface.

Intelligent Hydraulic Protection: The system was equipped with real-time pressure monitoring. When tramp iron or uncrushable boulders enter the chamber, the hydraulic cylinders instantly retract the movable roller.

Intelligent Hydraulic Protection

Low-Rotation High-Torque: By optimizing the motor power to 2×132kw, HSM achieved high-throughput crushing while reducing total energy consumption by 20% compared to traditional secondary crushers.
