Guizhou case: Right crusher, stable output, efficient sulfur concentrate from coal gangue.

Coal gangue has complex composition, fluctuating hardness, and varied impurities, placing high demands on crusher discharge accuracy and operational stability. A coal gangue processing project in Guizhou selected the Hua Sheng Ming 2PGY1010 hydraulic roll crusher for coal gangue fine crushing after extensive evaluation. Since commissioning, the equipment has operated stably with excellent crushing results, earning high recognition from the customer.

Project Overview

A customer in Guizhou is engaged in coal gangue processing, with complex material composition and high moisture content, requiring precise discharge size and production stability. After comparing multiple equipment options, the customer selected the Hua Sheng Ming 2PGY1010 hydraulic roll crusher for coal gangue fine crushing.

Equipment Configuration

The project uses the Hua Sheng Ming 2PGY1010 hydraulic roll crusher with the following key configuration:

Two heavy-duty motors

Full hydraulic adjustment system, feed size ≤40mm, uniform discharge, smooth operation

The high-quality power system ensures continuous and stable operation, maintaining efficient crushing even when processing coal gangue with high hardness and complex impurities. The equipment features a compact structure with good sealing, meeting environmental requirements.

Operating Parameters and Performance

Material: Coal gangue
Feed Size: ≤30mm
Discharge Size: ≤3mm

The Hua Sheng Ming 2PGY1010 hydraulic roll crusher uses a low-speed compression process with a screenless bottom design, specifically optimized for sticky and wet materials like coal gangue. After commissioning, the equipment delivers uniform discharge size meeting customer production requirements.

During operation, the equipment demonstrates the following characteristics:

Stable Production – Efficiently Meeting Production Needs
The equipment capacity matches the customer’s production scale, ensuring continuous and stable operation.

Uniform Discharge – Reliable Product Quality
Precise roll gap control ensures concentrated particle size distribution, meeting downstream process requirements.

Smooth Operation – Easy Maintenance
The equipment features a simple structure with low failure rate and minimal daily maintenance.

Key Process Advantages

For coal gangue processing, the roll crusher offers several process advantages:

Strong Adaptability to Moist Materials
Coal gangue often contains moisture and clay during mining and stockpiling. Conventional crushers with screens are prone to clogging and frequent shutdowns. The roll crusher features a screenless bottom design, controlling discharge size through roll gap adjustment, fundamentally eliminating this issue.

Precise and Adjustable Discharge Size
The hydraulic gap adjustment system supports flexible roll gap adjustment, allowing discharge size to be adjusted according to downstream process requirements to meet different production conditions.

Gentle Liberation – Reduced Over-grinding
The roll crusher uses a “low-speed, high-torque compression” inter-particle crushing principle, allowing pyrite crystals to separate along natural bonding surfaces. This ensures mineral liberation while effectively reducing fines generation.

Customer Feedback

After actual production verification, the Guizhou customer gave high praise to the Hua Sheng Ming equipment:

“This roll crusher delivers high output, reliable quality, stable operation, and is very reassuring to use.”

The customer’s recognition is the truest testament to Hua Sheng Ming’s manufacturing capabilities.
