The Double Stage Crusher, also known as the two-stage non-screen-bottom crusher, integrates two hammer crushers into one with an up-and-down series connection. It is widely used in mining, building materials, coal, brick making and other industries. Mainly for fine crushing of medium and low-hardness materials such as coal gangue, slag, shale and construction waste.
Double Stage Crusher: Industrial Crushing Equipment for Fine Crushing, Wet & Dry Universal
Equipped with an upper and lower double-rotor structure. Materials are roughly crushed by the upper rotor and then immediately fed into the lower rotor for re-fine crushing. Inside the crushing chamber, materials collide and strike with each other, realizing the “material-on-material, hammer-on-material” crushing principle. It achieves one-step forming without secondary processing, with uniform discharge particle size that can be stably controlled below 3 mm in most working conditions.
Its core advantage lies in the non-screen-bottom design, which solves the problem of easy blockage in traditional crushers when handling high-moisture materials. There is no restriction on moisture content; wet and sticky materials can be crushed smoothly. Greatly reducing downtime for cleaning. Paired with high-alloy wear-resistant hammers and displacement clearance adjustment technology. The hammers can be reused after adjustment once worn, significantly extending service life and reducing operation and maintenance costs.
The whole machine features compact structure, stable operation, convenient maintenance, low energy consumption and high output. It not only realizes the resource utilization of solid waste, but also meets the refined material requirements for brick making, aggregate production, batching and other applications. It is an ideal choice for crushing in small and medium-sized production lines, with outstanding cost performance and practicability.
