Double stage Crusher

Product description

The Double-stage Crusher (also known as a stage-linkage crusher) is a revolutionary fine-crushing device designed specifically for materials with high moisture content. By integrating two sets of rotors into one machine body, it achieves the crushing effect of two hammer mills working in series, but with much higher efficiency and a smaller footprint.

Why is the Double-stage Crusher a Game-Changer?

Screenless Design (Zero Clogging): There is no screen grate at the bottom. Even if the moisture content of the coal or shale is high, the material passes through smoothly, completely solving the “rainy season shutdown” problem.

Dual Rotor Fine Crushing: The upper rotor performs coarse crushing, and the lower rotor instantly performs fine crushing. This “hammer-on-material” technology ensures a fine, uniform discharge.

High-Manganese Alloy Hammers: Our hammer heads are made of specialized wear-resistant alloys, offering a service life 2-3 times longer than traditional cast iron hammers.

Easy Maintenance: The hydraulic opening system allows you to open the casing in minutes for quick hammer replacement or internal inspection.

Field Applications

Widely used in brick factories to process shale and coal gangue, and in power plants for coal crushing. Its ability to produce fine particles (<3mm) makes it the perfect pre-grinding equipment for many industrial processes.

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.
