6 major differences between ordinary jaw crusher and European jaw crusher

Ordinary jaw crushers and European jaw crushers have their own characteristics and are suitable for different scenarios. It is impossible to simply judge which one is better. The following is a main comparison between the two:

1. Structural design

The structural design of ordinary jaw crushers is relatively traditional. The bearing seat and the frame are usually welded, and the overall stability is relatively weak. Under long-term high-intensity operation, problems such as cracking of the welding parts may occur, which will affect the service life of the equipment.
The European version of the jaw crusher adopts a non-welded integrated frame and an integral cast steel structure, which can withstand greater impact and vibration, and has significantly enhanced stability and durability. At the same time, the larger eccentric shaft and higher-specification bearing design increase the load-bearing capacity of the equipment and extend its service life.

2. Feeding and crushing chamber
Generally, the jaw crusher adopts a semi-V-shaped or oblique V-shaped crushing chamber. The width of the feeding port is relatively narrow, and the ability to handle large-sized raw materials is limited. The flow path of the material in the crushing chamber is not optimized, which is prone to blockage and affects the crushing efficiency.
The European version of the jaw crusher adopts a symmetrical deep V-shaped crushing chamber design, which increases the width of the feeding port and can handle larger-sized raw materials. At the same time, the optimized material flow path enables the material to be fully crushed in the crushing chamber, reducing the blockage and return of the material, and improving the crushing efficiency.

3. Discharge port adjustment
Ordinary jaw crushers mostly use gaskets or manual adjustment of the discharge port, which is relatively cumbersome to operate, with low adjustment efficiency, and it is difficult to accurately control the size of the discharge port, which easily leads to uneven discharge particle size.
The European version of the jaw crusher adopts hydraulic adjustment of the discharge port and locking spring safety device, which can achieve precise control through simple operation, reduce the frequency of manual intervention, simplify the maintenance process, ensure the uniformity of the discharge particle size, and help improve production efficiency and product quality.

4. Lubrication system
Ordinary jaw crushers usually use grease for lubrication, which is easy to leak and oxidize, consumes quickly, and needs to be replaced frequently, which not only increases maintenance costs and workload, but also may affect the normal operation and service life of the equipment due to poor lubrication.
The European version of the jaw crusher uses engine oil for lubrication, which has high fluidity and good lubrication effect, and can effectively improve lubrication efficiency and equipment maintenance convenience. At the same time, the lubrication system and cooling system of the equipment adopt advanced technology, which can ensure that key components maintain good lubrication and cooling status during long-term operation, reducing long-term operation and maintenance costs.

5. Crushing efficiency and power
The output power of ordinary jaw crushers is relatively small, and the crushing efficiency of materials in the crushing chamber is low. When processing hard materials or large production requirements, it may seem powerless, resulting in low production efficiency.
The output power of the European version of the jaw crusher is higher than that of ordinary jaw crushers under the same specifications. Its optimized crushing process and efficient power system make the equipment consume less energy under the same conditions. At the same time, the optimized operating parameters make the material begin to be crushed in the upper part of the crushing chamber, so as to obtain a larger stroke in the lower part, further improving the crushing efficiency.

6. Price and cost
The price of ordinary jaw crusher is relatively low, and the initial investment cost is small, which is attractive to users with limited budget or small production enterprises. However, its maintenance cost and energy consumption are relatively high, and long-term use may increase the overall cost.
Although the price of European jaw crusher is higher, it has more advantages in long-term use due to its high efficiency, low maintenance cost and long service life, which can bring higher economic benefits to users. It is a better choice for large manufacturers or users with high requirements for production efficiency and product quality.

If the budget is limited and the performance requirements are not high, ordinary jaw crushers are more economical and suitable for small and medium-sized enterprises and small-scale production. If high-performance and high-stability equipment is required and the budget is sufficient, the European jaw crusher is a better choice, especially suitable for large-scale production in large-scale mining, building materials and other industries.
