Main Frame of Cone Crusher


Main Frame of Cone Crusher

The frame is the skeleton structure of the crusher and supports all the working parts. Cone crusher frame mainly uses ZG270-500 high-quality steel to customize the upper and lower frames, top and bottom shells of the cone crusher. And CHAENG continuously summarizes casting experience and improves process technology, to produce the frame with sufficient rigidity, strength and accuracy of geometric dimensions.

Shenyang Tianyi Mining Machinery Co., Ltd. can provide all types of multi-cylinder cone crusher main frame.
Product quality meets international standards, and we provide tailor-made prices and construction periods to meet their needs.

Regular maintenance

In addition to the major, medium and minor repairs according to the regulations, the cone crusher should be regularly overhauled every 35-45. Its contents are as follows:

2 Check the wear of straight bushes and cone bushes;

3 Check and adjust the gear meshing gap;

4 Check the gap of the drive bearing bush;

5 Check and clean the liquid device and lubrication device;

6 Check and clean the sealing device and dust ring;

7 Repair or replace some small parts.
