Analysis Of Components Of 600 × 900 Jaw Crusher

Last Update:2020-05-07 10:01:59

The main components of 600 × 900 jaw crusher are: frame, fixed jaw plate, movable jaw plate, upper and lower guard plate, adjusting seat, eccentric shaft, adjusting device, flywheel, lubricating device, movable jaw pull rod. Understanding the internal structure of 600 × 90 jaw crusher can help the use of jaw crusher and problems. This article will take you to understand the various parts and functions of the jaw crusher.

The first is the frame: the frame 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 the broken materials. It is required to have sufficient strength and rigidity. Generally, it is cast by cast steel as a whole. 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 frame of self-made small jaw crusher can also be welded with thick steel plate, but its rigidity is poor and it is easy to wear.

Then there is the regulating device: the regulating device has wedge type, base plate type and hydraulic type, etc. Generally, the wedge type is adopted, which is composed of front and rear wedge blocks. The front wedge block can move back and forth to counter the push back plate. The rear wedge block is an adjustable wedge, which can move up and down. The inclined surfaces of the two wedge blocks are facing backward and fit each other. The screw makes the rear wedge move up and down to adjust the size of the discharge port.

The last is the lubrication device: the eccentric shaft bearing is 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 it difficult to lubricate between the spindle and the bearing bush. 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.

The tacit cooperation of various parts is the premise and an important link to ensure the normal operation of the machine. Without the protection of the frame, the broken stones fly all over the world, which is full of potential safety hazards; without jaw plate and side guard plate, the machine cannot break materials; without transmission parts, the machine cannot operate; without lubrication device, the bearing may break. So all parts are indispensable. Among them, the power of jaw crusher can be different according to the size of the assembled motor.
