The machine features a simple and compact structural design, which not only improves operational stability but also makes installation, operation, and maintenance more convenient. Fewer wearing parts mean lower maintenance frequency and reduced downtime, further minimizing maintenance costs. The robust frame and high-strength rollers ensure stable performance even during continuous operation under heavy loads.
Another important feature of the PG Roller Crusher is its flexible adjustment capability. The discharge size can be easily adjusted by changing the gap between the two rollers, allowing operators to precisely control the final particle size according to production requirements. This flexibility makes the crusher adaptable to different processing stages and varying material characteristics.
The roller surfaces can be customized in different forms — smooth rollers, grooved rollers, or toothed rollers — depending on the material type and working conditions. This enhances crushing efficiency and improves the machine's ability to handle materials with varying hardness, moisture content, and particle size.
With its simple structure, flexible operation, low operating costs, and stable performance, the PG Roller Crusher is widely used in continuous and large-scale production lines. It provides a practical, economical, and efficient crushing solution for precise particle size control.

The PG Roller Crusher is a compression-type crushing machine that uses two counter-rotating rollers to crush materials. It is mainly used in continuous and large-scale production lines for processing materials such as coal, limestone, clay, and other medium-hardness materials. It is valued for its precise particle size control, low operating costs, and stable performance.
The output particle size is adjusted by changing the gap between the two rollers. Operators can precisely control the final particle size according to their production requirements, making the crusher highly adaptable to different processing stages and varying material characteristics.
The roller surfaces can be customized in different forms to suit different applications: smooth rollers for fine crushing of brittle materials, grooved rollers for improved grip on harder materials, and toothed rollers for processing materials with higher moisture content or larger initial particle sizes.
The capacity varies significantly depending on the model. Smaller models offer a capacity of 2–10 t/h, while larger models such as the 2PG2000×1200 can reach up to 490 t/h. The four-roller (4PG) series also provides varied capacities, making the PG Roller Crusher suitable for both small-scale and heavy industrial applications.
The 2PG series is a double-roller crusher featuring two rollers, suitable for primary or secondary crushing. The 4PG series is a four-roller crusher that performs two stages of crushing in a single pass, capable of achieving finer output sizes, making it ideal for applications requiring higher fineness and greater production capacity.
The PG Roller Crusher is designed with a simple and compact structure that minimizes the number of wearing parts. Fewer wearing parts mean lower maintenance frequency and reduced downtime. The robust frame and high-strength rollers are engineered to withstand continuous operation under heavy loads, ensuring long service life.
