MCC StoneSizer roller bearing crushers utilize an up-thrust toggle action and are strongly built for primary rock crushing. They are engineered to produce high outputs of material down to a closed-side setting of 20mm, even in some of the most demanding operating conditions.
Every machine is designed to achieve maximum reduction of material while maintaining stability and reliability in continuous operation. Each unit is fabricated by hand and incorporates a proven all-welded steel body, ensuring durability and long-term performance in heavy-duty industrial environments.
