Un-comparable reliability and productivity

Features :

The reliability of RJC Series jaw crushers is based on a revolutionary Extra Stroke & Heavy Design Jaw Crusher, non-welded pedestal  frame construction. This design provides excellent fatigue strength even in toughest quarrying or mining applications.

Roljack jaw crushers are the most productive and cost-efficient jaw crushers for any primary & secondary crushing application. Jaw crushers were originally developed to crush the hardest ores and rocks so they perform extremely well also in less demanding applications, such as soft rock, recycling and slag.

Roljack's foundry expertise enables continuous steel casting development to ensure the best casting designs and quality in terms of strength and fatigue life. High level of engineering combined with top-of-the-line commercial components, such as spherical roller bearings, ensure the reliability that ROLJACK jaw crushers are known for there best in all.

Benefits :

Excellent material intake capacity, Feed opening depth, which typically defines the top feed size, is well balanced with the width and height of the crusher. A good feed opening depth enables excellent material intake capacity and ensures that the rocks enter the cavity without restrictions.

Excellent bite in the cavity The steep nip angle, the angle between the movable and fixed jaw dies, ensures good bite and good material flow down in the cavity. On top of great performance, a good nip angle also reduces wear on the jaw dies and that has a direct impact on operating costs.

High production and reduction jaw crushers are well known for the aggressive motion of the pitman and long stroke in the bottom of the cavity. This boosts the capacity as well as the reduction ratio, resulting in high production and better end-product gradation.
