Wear cone crusher performance is closely related to the quality of its consumables. Crusher wear wearing parts of the main spindle and taper bushing wear, eccentric sleeve and straight bushing wear, wear plate and push the gear rack and the spherical bearing wear, wear only the crushing chamber. This paper will analyze these types of wear and tear on the crusher, as well as the design and manufacture of the crusher, use and maintenance to provide a theoretical reference.

1) Wear the crushing chamber

Crushing chamber parallel region worst wear and maximum wear in the cone parallel to the entrance area, the maximum dynamic cone liner wear at the discharge port on the side. Wear and tear than the entire area of ​​the upper chamber parallel wear large. After the crushing chamber and wear, crusher cavity shape change is large and completely lost prototype, seriously affecting the crushing effect crusher.

2) taper spindle and bushing wear

In normal operation of the crusher, cone spindle and bushing are catchy cone liner down about about 400mm in height significant wear prints. If the spindle and taper bushing in the lower and the upper wear heavier but lighter, then moving cone instability phenomenon will produce mild, the crusher can not operate normally. If there is a lower end of the spindle and the taper bushing local contact in the case, it will taper bush crack damage.

3) Wear thrust plate and gear

The thrust plate along the outer wear more serious, because the linear velocity of the outer ring, it is also more wear and tear in the ring soon. And because the eccentric sleeve skew has increased its outer wear. When the crusher operation, the large bevel gear in a straight bushing gap is generally a radius around the center line crusher circular motion, which would generate an additional shock and vibration gear and additional wear during operation, shorten gear life.

4) frame and the spherical bearing wear

Spherical bush wear is a process of progressive development from the outer circle to the inside. Use late, moving cone may cause instability, stuck in the mouth under the spindle taper bushes, leading to lower tapered bushing mouth cracks and damage, and even "speed" phenomenon, spherical tile damage, except normal wear and tear is to produce crack.

5) eccentric bushing wear sleeve and straight

Wear performance of the eccentric sleeve in the direction along the height of the eccentric sleeve, the upper portion and the lower end heavy wear slight wear. The degree of wear of the upper portion is gradually reduced downward. Cone crusher operation, the upward movement of the liner often appear straight, straight liner cracks and other phenomena. Straight after the liner channeling more likely to cause cracks, but straight after the liner crack, debris generated by cutting a hole surface of the chassis center will make it out of round; crack debris on the eccentric sleeve is particularly serious damage, the machine will the deterioration of working conditions, and even cause serious accidents.
