Maintenance method for main components of cone crusher

The cone crusher can guarantee the high efficiency and the daily maintenance. The maintenance here is mainly the maintenance and maintenance of important parts. Let's take a look at the maintenance methods of the main components of the cone crusher given by Jiaozuo Zhongxin technical engineer.

1. Maintenance of the feeding device, the ore distribution in the crusher is uneven. This will cause the fixed umbrella plate and the adjusting ring to be partially worn, resulting in defective products and reduced productivity. In severe cases, the side of the crusher is reversed, thereby increasing the bearing pressure of the spring and accelerating the wear of the mating slope of the support sleeve and the flange portion of the body.
Therefore, before the ore enters the crusher, the finely divided powdery material and the oversized bulk material are left to be disposed outside the machine by means of a screening device. In order to ensure that the granularity of the incoming machine is relatively uniform, the above accidents are avoided.

2. Maintenance of the eccentric component, which consists of an eccentric shaft, a tapered vertical shaft bushing and a cylindrical eccentric sleeve. The eccentric shaft should be more flexibly fitted into the bronze or babbitt eccentric bushing of the body, and the tapered vertical shaft should also be flexibly fitted into the tapered vertical shaft bushing on the eccentric shaft. The working part of the crusher cannot exceed the normal gap by 1.5 times due to the increase of the wear gap.
During the inspection, the fit of the cylindrical eccentric shaft bushing to the eccentric shaft bushing hole on the body must be checked. When the bushing is too loose, repair, adjust or replace it in time.

3. Maintenance of the support sleeve, premature wear of the serration thread of the support sleeve and the adjustment ring, which affects the operation of the equipment is a common matter. For this purpose, the pin on the casing must be firmly wedged with a wedge iron. And can't boot when there is no locking condition.

4, the maintenance of the fixed cone, the component is composed of an adjustment ring, a fixed umbrella plate, a "v"-shaped screw platen and the like. The fixed umbrella plate on the adjusting ring is subjected to a large impact load under working conditions, and the zinc filling layer is easily deformed. Therefore, in order to fix the umbrella plate without loosening, it is necessary to maintain it frequently and tighten the nut, otherwise the zinc filling layer will fall off, so that the zinc filling layer or the replacement part should be poured again.
