1. Project Background & Client Profile
A mineral processing enterprise in Guizhou Province, China, has invested in a comprehensive gangue utilization project to actively respond to the national strategy of “in-depth development of rich minerals.” The project aims to collect gangue from surrounding coal mines and extract high-quality sulfur concentrate (with a sulfur content of up to 45%) through modern gravity separation and flotation processes, serving as a vital chemical raw material for sulfuric acid and fertilizer production. To ensure the smooth operation of the downstream mineral processing, the project urgently required a primary crushing system capable of precise particle size control and handling high-hardness materials.

2. The Challenge: Severe Over-Crushing & Insufficient Liberation
Before introducing Huashengming equipment, the enterprise faced severe production bottlenecks in the gangue pre-processing stage:
Before introducing Huashengming equipment, the enterprise faced severe production bottlenecks in the gangue pre-processing stage:
High Over-Crushing Rate: Traditional impact crushers generated excessive fine powder when processing gangue, which not only reduced the effective liberation degree of pyrite but also increased reagent consumption and processing costs in the subsequent flotation stage.
High Hardness Leading to Wear & Jamming: Gangue often contains high-hardness rocks and iron impurities. Traditional equipment lacks a yielding protection mechanism, making it highly susceptible to jamming when encountering uncrushable objects. Furthermore, frequent replacement of wearing parts resulted in high maintenance costs.
Uneven Discharge Size: The old equipment produced inconsistent output sizes, with a mix of large gangue blocks and fine powder, failing to meet the strict feed size requirements of the downstream grinding equipment.

3. The Huashengming Solution
Targeting the specific characteristics of Guizhou gangue sulfur extraction—which requires “precise liberation and avoids over-crushing”—Huashengming Heavy Industry customized a Double-Toothed Roll Crusher. Designed specifically for solid waste resource pre-processing, its core advantages directly address the pain points:
Targeting the specific characteristics of Guizhou gangue sulfur extraction—which requires “precise liberation and avoids over-crushing”—Huashengming Heavy Industry customized a Double-Toothed Roll Crusher. Designed specifically for solid waste resource pre-processing, its core advantages directly address the pain points:
Selective Shearing for Precise Liberation: Utilizing the shearing principle of two relatively rotating toothed rollers, it forms a rotating spatial grating. Gangue meeting the particle size requirements falls directly through, while only oversized blocks are instantly sheared and crushed. This “flexible crushing” significantly reduces the over-crushing rate and effectively improves the monomer liberation degree of pyrite.
Flexible Yielding to Handle Impurities: Equipped with a flexible gap adjustment and yielding protection mechanism, the toothed rollers can automatically retract and discharge when encountering uncrushable objects like iron blocks, completely eliminating jamming issues. Additionally, the specially wear-resistant steel rollers greatly extend the service life.
High Efficiency & Uniform Discharge: The double rollers operate smoothly with a uniform discharge size, perfectly matching the feed standards of downstream grinding equipment and laying a solid foundation for extracting high-grade sulfur concentrate.
4. Operational Results & Client Feedback
Since the Huashengming Double-Toothed Roll Crusher was put into operation, the enterprise’s gangue sulfur extraction production line has seen significant improvements:
Since the Huashengming Double-Toothed Roll Crusher was put into operation, the enterprise’s gangue sulfur extraction production line has seen significant improvements:
Upgraded Mineral Processing Indicators: Crushing efficiency has markedly increased, and the uniform discharge size ensures effective liberation of pyrite. The grade and recovery rate of the downstream sulfur concentrate have successfully met the expected targets.
Significantly Reduced Maintenance Costs: The issues of jamming and excessive wear have been completely resolved, greatly reducing downtime and daily operational expenses.
Prominent Economic Benefits: Stable primary crushing ensures the highly efficient operation of the entire production line, enabling the enterprise to comprehensively extract sulfur resources from gangue, turning environmental pressure into innovative momentum.
Coal gangue product
“With the old crusher, there were too many fine powders, resulting in poor pyrite liberation and high flotation costs. Since switching to the Huashengming double-toothed roll crusher, the discharge is uniform and the machine is highly durable. It has made a great contribution to our gangue sulfur extraction project in Guizhou, truly turning coal into gold!”
