Double Roll Crusher (High Pressure Roller Crusher)
Capacity: 20-250 t/h | Feed Size: ≤600mm | Output Size: 0.5-40mm
The double roll crusher, also known as roller crusher or twin roll crusher, is a high-efficiency crushing machine designed for medium-soft materials sand making and size reduction.
The machine uses two counter-rotating rollers to generate high pressure compression force (50–200 MPa), crushing materials into uniform particles with low dust and low energy consumption.

What is a Double Roll Crusher?
A double roll crusher is a compression-type crushing equipment that reduces material size by squeezing it between two rotating rollers. Unlike impact crushers, it produces:
- More uniform particle shape
- Lower over-crushing rate
- Stable gradation control
It is widely used for sand making, material pre-crushing, and fine crushing applications.
Applications
The double roll crusher is suitable for a wide range of industries:
- Mining & Aggregate Industry: River stone crushing, Limestone sand making, Gravel and aggregate processing
- Construction Industry: Sand production lines, Road base material preparation, Building aggregate crushing
- Cement Industry: Raw material pre-crushing, Limestone size reduction
- Power & Energy Industry: Coal crushing, Fuel preparation
- Recycling Industry: Construction waste crushing, Slag and industrial waste processing
Applicable Materials
This roller crusher is designed for medium-hard and soft materials, including:
- River stone
- Limestone
- Coal gangue
- Shale
- Gypsum
- Slag
- Construction waste
Material hardness: ≤150 MPa compressive strength
Working Principle
Material Feeding: Material enters the crushing chamber from the top.
High Pressure Compression: Two high-strength rollers rotating in opposite directions apply strong compression force (50–200 MPa).
Crushing & Discharging: Material is crushed between roller surfaces and the finished product is discharged through the adjustable gap.
Key Features & Advantages
- ✔ High Pressure Compression Crushing: Dual rollers generate strong squeezing force, ensuring uniform particle size, better sand shape, and stable grading.
- ✔ Adjustable Output Size (0.5–40mm): Hydraulic or wedge adjustment system allows precise particle control, flexible production requirements, and easy operation.
- ✔ Dry & Wet Material Compatible: No need for drying or pre-treatment. Suitable for humid and rainy environments with stable performance.
- ✔ Energy Efficient Design: Up to 20% lower energy consumption than traditional crushers, low operating cost, and high throughput efficiency.
- ✔ Simple Structure & Easy Maintenance: Compact design, low failure rate, easy roller surface replacement, and minimal maintenance requirements.
