Four roller crusher

Product description

High-Efficiency Two-Stage Crushing: Four Roller Crusher Performance

The Four Roller Crusher is the ultimate solution for tasks requiring a high crushing ratio in a single pass. By combining medium and fine crushing into one compact machine, it eliminates the need for multiple conveyors and additional screening equipment.

Project Specifications

• Material: Limestone / Coke / Sintering Return
• Feeding Size: ≤ 90mm
• Output Requirement: 2-8mm (Adjustable)
• Moisture Content: Up to 30% (Non-clogging)

Technical Advantages of the Four-Roller System

1. Integrated Two-Stage Crushing

The upper pair of rollers performs the initial medium crushing, reducing large lumps to a manageable size. The material then falls by gravity to the lower pair for precision fine crushing. This “stepped” approach reduces the load on individual motors and extends component life.

2. Superior Particle Uniformity

Unlike standard crushers, the dual-cavity design ensures that oversized particles are virtually eliminated. This produces a highly consistent 3-5mm product, which is critical for sintering plants and chemical production lines.

3. All-Weather Reliability

With its screenless discharge design, this machine handles wet or sticky materials (up to 30% moisture) without the risk of clogging, ensuring stable production even during the rainy season.

Client Success Story

After replacing our traditional hammer mill with the HSM Four Roller Crusher, our maintenance downtime dropped by 50%. The output size is perfect for our downstream ball mill feed, and the energy savings have been substantial.”

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.
