The PG Roller Crusher is built for continuous heavy-duty operation. Equipped with wear-resistant alloy rollers and a high-strength frame structure, it delivers stable crushing performance with minimal downtime.
Its adjustable gap control system allows precise output sizing, while the optimized transmission system reduces power consumption and mechanical stress.
Designed for long service life and easy part replacement, it is widely applied in cement plants, mining operations, and bulk material processing industries.
The PG-Series Roller Crusher is engineered for secondary and fine crushing of medium-hard and brittle materials. Its dual-roller compression mechanism ensures controlled particle size reduction while minimizing excessive fines.
The adjustable discharge gap allows precise output size control, making it suitable for applications requiring uniform material grading. The heavy-duty frame structure and wear-resistant alloy rollers ensure stable performance under continuous industrial operation.
Designed for seamless integration into crushing systems, the PG Roller Crusher works efficiently with feeders, conveyors, and screening equipment in mining and cement production lines.
The PG Roller Crusher operates based on a compression crushing mechanism between two counter-rotating rollers. Raw material is drawn into the crushing chamber through friction between the rollers and the material surface.
As the rollers rotate inward, the material is compressed and fractured under high pressure. The adjustable gap between the rollers determines the final output size, ensuring uniform particle distribution and minimal over-crushing.
This low-speed compression process reduces dust generation, vibration, and excessive fines compared to impact-based crushing systems.
1. Material Feeding – Bulk material enters the crushing zone from the top feed opening.
2. Roller Compression – Two counter-rotating rollers pull the material inward and applycompressive force.
3. Controlled Size Reduction – Material fractures progressively under pressure.
4. Gap Adjustment – Adjustable roller spacing defines final discharge size.
5. Stable Continuous Operation – The drive system ensures synchronized rotation foruninterrupted production. final output size.
