thyssenkrupp has two types of jaw crushers in its product range: Single-toggle jaw crushers for a high throughput rate, and double-toggle jaw crushers for extremely hard materials and abrasive rock.
Single-toggle jaw crushers
Single-toggle jaw crushers are ideal for maximum throughput rates when crushing medium-hard and hard materials. They are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against the crusher frame by means of a toggle plate. This system results in a higher capacity than that achieved with a double-toggle jaw crusher with the same feed opening. Available in various sizes, they achieve throughputs of 250 t/h to 1,400 t/h.
Double-toggle jaw crushers
Double-toggle jaw crushers are the ideal machines for the hardest and most tenacious materials. They are equipped with a double-toggle system, which is controlled by a pitman that moves up and down under the influence of an eccentric shaft, causing the toggle plates to alternately flex and stretch. As a result, the swing jaw oscillates. This system ensures very good power transmission from the drive unit to the crushing mechanism, making double-toggle jaw crushers ideal for crushing extremely durable materials. Another advantage is the high wear resistance due to the kinematics of the crusher.
