By adopting the world’s most advanced crushing and manufacturing technology, European type jaw crusher is mainly used for secondary and tertiary crushing of various medium-hard ores and rocks. European type jaw crusher has already become the most popular equipment in the world without controversy. It is the first choice for hard and strong abrasion material. [pic]
1. Adopt world-level manufacturing techniques and raw materials. 2. Movable jaw assembly is made of high-quality cast steel piece. Forging blank is adopted for heavy eccentric shaft for processing, which makes the machine more reliable and endurable. 3. Integral cast steel structure is adopted for bearing saddle to guarantee full cooperation with crushing stander, which greatly enhances radial strength of bearing saddle. 4. Adoption of finite element analysis technology ensures much higher strength of the machine. 5. Crusher chamber adopts “V” structure which could make the actual feed width complies with the nominal one. 6. Adjustment device with discharge hole with wedge installed is simpler, safer and rapider than the old spacing piece. 7. Compared with crusher of other specifications, all machines of the series adopt more endurable and bigger eccentric shaft bearing; its higher bearing capacity and effective labyrinth seal make service life of bearing greatly prolonged. 8. The latest tooth-shaped guard plate is adopted to increase effective length of jaw plate and improve output. [pic]
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves. So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling...
