Global Success Story

200 TPH Coal Gangue Solid Waste Utilization Project

Upgrading Eco-Friendly Fine Grinding Circuits with HSM Intelligent Systems

Project Overview

A prominent mining group required an industrial-grade infrastructure solution to reprocess highly abrasive coal gangue into specialized fluid-bed boiler fuel and eco-brick aggregates. The primary engineering bottleneck involved preventing severe machine clogging from high-moisture feed, while simultaneously ensuring a strict 0-10mm particle distribution without relying on high-wear hammer modifications.

Project Profile:

Raw Feed: Coal Gangue

Target Flow: 200 t/h

Infeed Limit: ≤ 80 mm

Core Gear: 2PGY1500×1200

Double Roller Crusher

Efficiency Benchmarks

Key Indicators	Conventional Mills	HSM Hydraulic Series
Moisture Tolerance	Frequent Clogging (>10%)	Flawless Flow (Up to 30%)
Wear Lifetime	High Cost (Quick Failure)	3-5x Alloy Extension
Operational Noise	Severe Impact Vibration	Enclosed Low Decibel

Technical Implementation

By utilizing the **HSM 2PGY1500×1200 Fully Hydraulic Double Roller Crusher**, the processing line successfully transitioned to an continuous static-extrusion loop. The custom high-chromium manganese alloy rolls eliminated premature surface wear from hard gangue inclusions, while the automated dual-cylinder pressure regulation maintained an exact discharge setting—maximizing fine combustion sizing while mitigating the blockages inherent to traditional screen-grates.

“
“The performance of the HSM 2PGY fully hydraulic double-roller system has transformed our solid waste recycling plant. Not only has it completely resolved our moisture-clogging issues during seasonal shifts, but the direct wear reduction has drastically enhanced our annual profit margins.”
