German version jaw crusher

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.



• Through the optimization of the overall structure and the counterweight part, the structure of the flywheel, the groove wheel and the weight of the counterweight are calculated and analyzed accurately, which effectively reduces the vibration level of the equipment and makes the equipment run more stable and reliable. The flywheel adopts a reasonable structure layout to better balance the unbalanced force generated by eccentric operation, avoid the machine damage caused by unbalanced vibration, and save the installation space. Two oversized bearings support the entire moving jaw for operation, making the equipment carry more load capacity and run more smoothly.
• The new frame design concept ensures the rigidity of the frame while reducing the installation space of the whole machine. The high quality cast steel moving jaw, forged eccentric shaft and large roller bearings make the HD series jaw crusher extremely reliable. The low suspension point design improves the bearing seat's stress condition and prolonging the service life of the bearing. The optimized motion parameters, combined with two large flywheels and the right speed, provide the HD Series jaw crusher with strong power and better crushing performance, allowing for finer crushing products. The upper and lower symmetrical curve tooth plate design, optimized tooth plate shape and thickness, effectively extend the service life of the tooth plate.
• The advanced bolting system of the side guard plate and the humanized lifting hole design make the replacement of the side guard plate and elbow plate more convenient and fast. In the lubrication process, the labyrinth seal structure is automatically filled with grease from inside to outside, which can effectively prevent dust or other fine particles from entering the bearing chamber to contaminate the grease, thereby extending the service life of the grease and equipment. Through the screw or hydraulic cylinder can easily and quickly realize the adjustment of the discharge port, greatly facilitate the operation and management of the site. The centralized lubrication system lubricates equipment without downtime, reducing worker labor and shortening maintenance time.

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
