Product description

The roller crusher (also known as double roller crusher) crushes materials via strong extrusion force after raw materials enter the crushing chamber, and the crushed finished products are discharged naturally from the bottom. When encountering excessively hard or uncrushable foreign objects, the movable roll can automatically retreat to protect the machine. It is mainly composed of roller wheels, supporting bearings, compression adjustment devices, and driving devices. Widely used in industries such as cement, chemical engineering, electric power, mining, metallurgy, building materials, refractory materials, and coal mining, it is particularly suitable for the intermediate crushing and fine-tuning of solid materials with a compressive strength of less than 250 MPa and a moisture content of less than 35%, as well as fine crushing operations where the discharge particle size can be freely adjusted between 0.5-20 mm.

Double-roll crushers can be used for sand production from:

Sand Production From Over 200 Materials Including River Pebbles, Cobblestones, Bluestone Slabs, Quartzite, Volcanic Rock, Iron Ore, Weathered Rock, Limestone, Granite, Sandstone, Marble, And Gypsum.

Double-roll crushers are suitable for fine crushing operations in mineral processing:

Fine Crushing Of Various Ores Including Gold Ore, Silver Ore, Tungsten Ore, Tin Ore, Magnetite, Copper Ore, Manganese Ore, Lead-Zinc Ore, Iron Ore, Graphite Ore, Chromite, Phosphate Ore, Metallurgical Silicon, Etc.

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.

Recommended Double Roll Crusher Models

1. Superior to hammer crusher with no wearing parts, pretty sand shape, and high capacity.
2. Suitable for sand plant, metal mine crushing, waste stone crushing, etc.with excellent quality.
3. Applicable for 200 kinds of stone materials, wet and dry stuffs with one button operation.
4. National patented roller skin material with service life ≥ 2 years.

Working Principle

The machine’ s gap between two rollers can be adjusted freely between 1mm-20mm. After the roller’ s gap is predetermined, the crushing grain size can be controlled reliably, and all of it is discharged from the lower part of the crushing chamber with ideal grain size.
