Description
Compared with the traditional jaw crusher, the SD German version of the jaw crusher has been greatly improved in terms of motion parameters, machine structure and adjustment methods. The integrated structure design of the motor base and the main engine makes the machine occupy less space, run more smoothly, and has more advantages in transportation, installation and maintenance adjustment, especially for fixed production lines and mobile crushing. The crushing chamber adopts symmetrical "V" type design, large tilt Angle, large stroke and reasonable speed of the elbow plate, so that the feed particle size is larger, the output is higher, the particle size is more uniform, the jaw plate wear is reduced, the machine maintenance rate and the failure rate are reduced, the service life is extended, and the comprehensive cost is lower.

Performance Advantages
- Reasonable crushing chamber design and good motion parameters make this HD German jaw crusher have a larger crushing stroke and greater carrying capacity, and the output can be increased by 30%-50% compared with other products of the same specification. The mechanical structure of the tooth shape of the jaw plate is optimized, and the segmented curved jaw plate and manganese steel alloy material are used to increase the thickness of the jaw plate, greatly enhance the crushing force, and effectively improve the production efficiency.
- Symmetric V-Shaped Cavity: Maximizes feed size and throughput while preventing material bridging/plugging.
- Heavy-Duty Cast Steel Moving Jaw: Ensures maximum structural integrity when processing ultra-hard rocks like granite and basalt.
- Wedge Discharge Adjustment: Replaces tedious shim adjustment, reducing downtime from hours to minutes.
- Integrated Motor Base: Compact design that reduces installation space and extends V-belt lifespan.
Working Principle
The main structure of German jaw crusher is composed of frame, eccentric shaft, fixed jaw, moving jaw, elbow plate, spring rod and other components. The working principle is that the motor drives the belt and pulley, and makes the moving jaw move up and down according to the predetermined track through the eccentric shaft. When the moving jaw plate pushes the fixed jaw plate, the material is crushed or split by gravity. When the moving jaw plate retreats, the broken material is excluded from the lower mouth of the crushing chamber, and the crushing motor jaw does periodic crushing movement as the eccentric shaft continuously rotates. The material entering the crushing chamber is continuously broken and discharged to achieve continuous production.

Question&Answer
Q:How to express the specifications of the jaw crusher? How to determine large, medium, and small?
A:The specifications of the jaw crusher are expressed by the width and length of the feed port, for example, the width of the feed port is 600mm, and the length of the crusher is 900mm. When the width of the feed port is greater than 600mm, it is defined as large, 300-600mm is defined as medium, and the feed port is smaller than 300mm, it is defined as a small jaw crusher
