Double Roller Crusher: The Ideal Choice for Sand and Aggregate Production

The double roller crusher, also known as a twin-roll crusher or roller sand making machine, marks a breakthrough in sand and aggregate production equipment. It uses two motors to drive twin rollers, applying pressure and grinding to crush materials. It is ideal for fine crushing operations where feed size is less than 80mm and output size ranges from 50 mesh to 20mm.

Why Choose Huashengming Double Roller Crusher?

No Frequent Part Replacements

Unlike hammer crushers, it eliminates the need for regular replacement of wear parts.

Superior Sand Quality

Produces well-shaped sand with reasonable gradation and minimal over-crushing.

Long-Lasting Durability

Roller sleeves last over two years, outperforming hammer and impact crushers.

Patented Technology

Huashengming’s high-chromium manganese steel rollers, precise discharge adjustments, and roller design are patented.

Suitable Materials

The double roller crusher is perfect for crushing and sand-making operations with materials such as:

PebblesCalciteQuartzGlassMarbleBasaltGraniteLimestoneIron oreWeathered sand

How It Works

The crusher uses two independently driven rollers rotating in opposite directions. The material fed between the rollers is crushed by compressive and grinding forces. When encountering unbreakable or excessively hard materials, the hydraulic cylinder or spring system allows the rollers to retract, protecting the machine from damage. The hydraulic system also controls the gap between rollers, ensuring adjustable discharge sizes.

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.    

The crusher uses two independently driven rollers rotating in opposite directions. The material fed between the rollers is crushed by compressive and grinding forces. When encountering unbreakable or excessively hard materials, the hydraulic cylinder or spring system allows the rollers to retract, protecting the machine from damage. The hydraulic system also controls the gap between rollers, ensuring adjustable discharge sizes.
