The Qing Shi Hydraulic Double-Roll Crusher is specifically engineered for optimizing bluestone crushing. Equipped with an advanced hydraulic system, i
t achieves highly efficient material compression and fragmentation. The model designation 1510 indicates rollers with a diameter of 1500mm and a length
of 1000mm. Suitable for medium to large-scale stone processing plants, it produces high-quality bluestone sand and aggregate widely used in construction,
landscaping, and decorative applications.
1. Working Principle
Double Roll Crusher
The Qing Shi hydraulic double-roll crusher utilizes two independently driven roller shafts that rotate in opposite directions to generate crushing and grinding forces
that break down materials. Material enters through the feed opening and falls between the rollers. After being crushed by the opposing rollers, the finished product
naturally discharges. When encountering excessively hard or uncrushable material, the rollers automatically retract via hydraulic cylinders or springs, increasing the
gap between them. allowing the hard or uncrushable material to pass through unharmed. This mechanism safeguards the machine from damage. The feed size of the
final product can be controlled by adjusting the pressure of the hydraulic cylinders or springs governing the opposing rollers.
