Over a hundred years of experience in the manufacture of jaw crushers
Fields of application and design characteristics
Jaw crushers are mainly designed for medium-hard to very hard materials and are used in quarries for primary crushing of blasted rockpile, which – depending on the blasting method – can achieve edge lengths of more than 2,000 mm. For these duties two different jaw crusher types are available from ThyssenKrupp Fördertechnik: single-toggle- and double-toggle jaw crushers. The distinguishing feature of these two crushers is the kinematics of the swing jaw which the specific advantage of the respective crusher type also results from.

The kinematics of such a toggle system results in a higher throughput capacity than that achieved with double-toggle jaw crushers with the same feed opening. Different feed material characteristics have led to a diversification of the singletoggle jaw crushers by rock hardness. Available in four sizes in light or heavy construction each,

They are based on theoretical calculations and verified by practical measurements. Deviations from the average throughput rate are dependent on: material, grain size, composition of the feed material, hardness, tenacity, degree of purity and feeding. Deviations normally to be expected for common materials and gap settings can be taken from the diagram.

The grain size distributions of the product are approximate values only. Deviations in the proportional composition are dependent on the factors also influencing the throughput rate. The stated grain size distributions refer to dry and brittle granite. For a surface-moist and tough basalt the fines content will be slightly lower and the curve will move to the right.

Double-toggle jaw crushers
Double-toggle jaw crushers: specially designed for hardest and toughest abrasive materials
Double-toggle jaw crushers are equipped with a system of toggle levers, which are moved up and down by a pitman via an eccentric shaft. The alternating stretching and bending movements cause an oscillating motion of the swing jaw. Since the material to be crushed falls down by gravitation, the pressure which is necessary to crush the material is generated, when the swing jaw moves forward in the narrowing crushing chamber. This process is intensified by the toothing on the crushing jaw liners. When the swing jaw retreats, the crushed material exits the crushing chamber through the pre-selected gap at the bottom, while new material slips down from the top.The toggle lever system ensures a very good power transmission from the drive unit to the crushing tools

Throughput rates and grain size distributions
The throughput rates of the double-toggle jaw crushers refer to hard feed material, which is easy to crush. They are based on theoretical calculations and verified by practical measurements. Deviations from the average throughput rate are dependent on: material, grain size, composition of the feed material, hardness, tenacity, degree of purity and feeding. When crushing a dry, brittle granite with a low feed material portion at the upper grain size limit, the expected throughput rate will be higher than that achieved with the crushing of a surface-moist, tough basalt with large feed lumps.
Deviations normally to be expected for common materials and gap settings can be taken from the diagram.
