The double-stage crusher, also known as the double-rotor screenless crusher. Is an ideal piece of equipment for processing high-moisture materials in industries such as mining, building materials, and metallurgy. Its core advantage lies in its “double-rotor series connection + screenless design”—after initial crushing by the upper rotor, materials are immediately subjected to high-speed hammering by the lower rotor. Achieving a dual crushing effect of “hammer-crushing material and material-crushing material.” This results in uniform particle size of the output, with over 90% of particles smaller than 2 millimeters.
Double-stage Crusher: A “Powerful Tool” for Efficiently Processing High-moisture Materials
This equipment overcomes the traditional crusher’s limitation of being “sensitive to moisture.” Its screenless grating bottom structure completely resolves the issue of blockage caused by high-moisture materials, enabling stable operation even when processing coal gangue, shale, or construction waste with a moisture content exceeding 10%. And eliminating the risk of motor burnout. Its high-chromium alloy wear-resistant hammers utilize a shift-adjustable gap technology. Allowing them to be reused simply by adjusting their position after wear, thereby extending their service life by three times. Coupled with a hydraulic opening and closing housing design, maintenance can be performed by a single person, significantly reducing downtime costs.
In the field of construction waste recycling. The double-stage crusher achieves “one-step crushing and sand making,” directly converting brick, stone. And concrete waste into recycled aggregates, thereby supporting green infrastructure development. Taking the SCF800x1000 model produced by Henan Huawei Machinery as an example. It can achieve a production capacity of 300 tons per hour. With energy consumption reduced by 20% compared to traditional equipment, making it a key piece of equipment in the circular economy.
