Jaw Crusher Machine
Jaw crusher working principle
Upper jaw hanging in the eccentric shaft directly, jaw crusher for sale. as the crank connecting rod, eccentric directly by the eccentric drive shaft, the bottom hinge of the jaw thrust plate support attached to the rear wall of the rack. When the eccentric shaft rotates, the moving jaw at various points along the trajectory is a line from the suspension point of the circle (radius equal to the eccentricity), and gradually down into an oval, the more down to the Ministry, the more oval-shaped side, until the lower thrust plate with connection point for the arc line trajectory. Because of this machinery moving jaw at various points along the trajectory is more complex, it is called complex swing jaw crusher. Reciprocate jaw crusher compared with the simple pendulum, and its advantages are: quality of light, fewer components, more compact, better degree of crushing cavity filled, the material blocks are evenly broken equipment, to move the lower jaw mandatory introduction of product discharge, and therefore higher productivity, compared with the specifications of the simple pendulum jaw crusher productivity 20-30%; material block in the lower jaw moving up and down rolling movement with large, easy to cubic shape unloading, reducing the swing as simple as a sheet product ingredients, product quality is better.
Jaw crusher and maintenance of the latest technologies crucial
Historically, our early days, the entire mining industry, no company or business can produce any crusher, or a broken device. Later, pioneers from the older generation of mining in the 1960s began to imitate the old-fashioned, foreign crusher, a gradual transition to self-designed, self-manufacturing stage. This is also used for China's mining crusher laid the foundation for the development and growth.stone crusher for sale. And we can learn from the older generation of pioneers who has been the biggest revelation is to always strive to maintain this tradition and innovation, in order to survive in the world peak of mineral processing equipment manufacturing industry instead of down.
Jaw crusher wear phenomena in daily operations is inevitable, we only do regular maintenance can extend the useful life to the maximum, so we Jaw crusher spindle, eccentric shaft and bearing long-term aspects of maintenance!
First, the axis of the wear and tear if rarely, just to fix its geometry, turning in a lathe, so that journal to the correct geometry, then the corresponding reduced bearing diameter. But after several such treatment, if the journal size reduction of 5% over the original, it does not allow re-turning, while the shaft should be replaced with new.
Again, the jaw crusher is working under the impact load, bearing on the babbitt lining, length of about two years or so, the deadline, you will need to re-cast. If the eccentric shaft and bearing, spindle and bearing are worn, the tip clearance gap of greater than 1.5 times the original assembly, the need to add pads to adjust or replace; oil groove wear 1.5 mm, should be re-opened the oil groove and adjustment. Connecting rod head cover and the gap between the eccentric shaft, wear and tear to 1.5 times greater than the assembly gap, the need to add pads to adjust or replace. When the bearing babbitt on a deeper peel or large scratches, should be re-cast. For the bearing quality after processing the following requirements: babbitt surface color to be uniform, light, silver white;Crushing Palnt For Sale. babbitt surface layer should not have ash, cracks, blisters, shrinkage, etc., and peel phenomenon.
