The double-stage crusher is a new type of crushing equipment upgraded and improved on the basis of the traditional hammer crusher, also known as the screenless double-stage grinder. With its unique design, it has become an ideal choice for processing high-moisture materials. Its core structure consists of two sets of series-connected rotors, which is equivalent to combining two hammer crushers into one. Coupled with high-alloy wear-resistant hammer heads, it realizes efficient crushing operations.

During operation, two motors drive the two sets of rotors to rotate at high speed. When materials enter the cavity, they are first coarsely crushed by the upper rotor and then finely crushed again by the lower rotor. The mutual collision between materials creates a crushing effect of “hammer crushing material and material crushing material”. The discharge particle size can be stably controlled below 3 mm. With particles smaller than 2 mm accounting for more than 80%.

The key advantage of this equipment lies in its screenless grate bottom design, which solves the problem of clogging caused by high-moisture materials. Even if the materials have high water content or are even water-bearing, it can operate normally on rainy days. Meanwhile, it features convenient maintenance, wear resistance, and stable output. Widely used in the crushing of medium and low-hardness materials such as gangue, shale. And construction waste, it serves as a core piece of equipment in brick factories. Building material plants, mines, and other industries, effectively reducing production energy consumption and maintenance costs.
