Double Roll Crushers are one of the most widely used crushers in the mining industry and have numerous advantages, such as high capacity, low headroom, low horsepower, the ability to handle wet, sticky feeds, and the ability to produce a cubical product with minimum fines generation. Roll diameters and widths are dictated by the feed size, product size, and capacity.

Technical Features

Dual roller design:

Features two parallel cylindrical rollers that crush materials through compression and shear forces. The gap between the rollers can be adjusted to control the output size.

High efficiency:

Ensures high crushing efficiency and uniform product size. Can easily handle a wide range of materials, providing consistent results while generating minimal fines.

Durable construction:

High-strength steel and wear-resistant materials withstand heavy loads and abrasive materials. Durable roller surface and bearings ensure long-lasting performance.

Adjustable output size:

The gap between the rollers can be precisely adjusted to achieve the desired output size. Meets specific requirements for different applications and material types.

Working Principle

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

Vest’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 bases, and other custom solutions.
