The double roller stone crusher is another breakthrough in the field of sand and gravel aggregate production equipment manufacturing.

The applicable materials for double roller crusher are very wide, such as calcite, limestone, phyllite, basalt, river stone, barite, etc., hundreds of materials.

Highway, railway, high-rise buildings, municipal, hydropower dam construction, concrete mixing station, sand and stone field, etc.

Operating Double Roll Crushers is quite simple. Whether it is a single or dual drive arrangement, the rolls are powered by electric motors and V-belt drive configurations, resulting in reliable and quiet operation. If it is a single-drive arrangement, power is transferred from the driven roll to the non-driven opposing roll by an interstage V-belt drive. If it is a dual-drive configuration, each roll is powered independently through a motor and V-belt drive.

During normal operation, the material is fed between the crushing rolls. A combination of compression and shear forces created between the opposing rolls reduce the feed material to the desired product size while producing a cubical product with minimum fines.

Cronus’s mechanical tramp relief systems employ a spring-and-toggle mechanism that activates whenever an uncrushable object enters the crushing chamber. Once an excessive force is applied to the movable roll, the toggles break open to allow the uncrushable item to pass. The high torsion springs then close the toggles, returning the movable roll to the previous setting. The crusher continues to operate uninterrupted.

Optional features include hydraulic product adjustment, roll scrapers, automatic lubrication, wheeled support base and other custom solutions.

The Double roller stone crusher is a two-roll sand-making machine that uses two motors to drive two roller shafts to squeeze and grind materials. The double roller crusher is mainly used for fine crushing operations with particle size requirements of less than 80mm and finished products of 50-20mm.

1. High crushing ratio and high production capacity The double-roller crusher is a double-roller sand-making machine that uses two motors to drive two roller shafts to squeeze and grind materials.

2. More crushing and less grinding, full grain size The production efficiency of the mill can be improved by crushing more and grinding less—delicate and high-quality finished products.

3 . Long service life and low operating costs The roller skin is made of wear-resistant materials with strong impact resistance and high wear resistance. It has a small loss and low failure rate when crushing materials. In the later stage, it can reduce maintenance costs, have low operating cost,s and long service life.
