The ore is too hard During the crushing process, if the ores are too hard, the impact force exerted on the chamber wall will increase, and the long-term impact and collision will aggravate the wear of the chamber and cause its damage. There are too much stone powder and moisture When the cone crusher works, if stones and rocks remain too much powder and moisture, they will easily stick to the concave and the mantle. After a long time, not only will the production efficiency be reduced, but also the mantle and the concave get corrosion and service life gets reduced. Improper feeding method The feeding mode of the cone crusher also has a material influence on the service life of the concave and the mantle. If the feeding equipment of the cone crusher is improperly installing, or if too many stones are feeding into the chamber, the material will be plugged in the chamber.
