Introduction To The Structure And Performance Of Xi'an E Crusher In Shaanxi Province

Last Update:2020-05-02 09:38:57

The jaw crusher is widely used in our country, such as in ore crushing production line. In different areas of our country, the emphasis of crusher development is different. Taking Shanxi e crusher as an example, 250 * 400 e crusher occupies a large market in this area. In Xi'an e crusher Market, customers can choose a variety of small e crushers.

First let's take a look at the frame of the jaw crusher. The frame of the equipment is a four wall rigid frame with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of broken materials. Generally, the frame should have enough strength and rigidity, and be cast integrally with cast steel. High quality cast iron can be used instead of cast steel. The frame of the mainframe needs to be cast in sections, and then firmly linked with bolts as a whole, so the casting process is complex.

The second is the jaw plate and side guard plate of the equipment. The fixed jaw and the moving jaw are both composed of the jaw bed and the jaw plate. The jaw plate is the working part, which is fixed on the jaw bed with bolts and wedge iron. The jaw bed of the fixed jaw is the front wall of the frame. The movable jaw bed should be hung on the circumference with enough strength and rigidity to bear the crushing reaction, so it is mostly composed of cast steel or cast iron.

The fourth is the adjustment device of the equipment. The regulating device has different forms such as wedge type, base plate type and hydraulic type. The equipment is generally wedge type, consisting of two front and rear wedges. The front wedge can be moved back and forth to counter the rear push plate; the rear wedge is an adjusting wedge, which can be moved up and down. The discharge port adjustment of small jaw crusher is realized by increasing or decreasing the number of gasket between the thrust plate support and the frame.

Finally, let's understand the lubrication device of the equipment. Eccentric shaft bearings are usually lubricated by centralized circulation. The supporting surface of the spindle and thrust plate is generally lubricated with grease through a manual oil gun. The swing angle of the moving jaw is very small, which makes the lubrication between the spindle and the bearing bush difficult. Usually, a number of axial oil grooves are opened at the bottom of the bearing bush, and a circular oil groove is opened in the middle to make it connected. Then, the oil pump is forced to inject dry grease for lubrication.
