Helps you maximize cone crusher productivity.
1. Ensure the materials are mixed evenly The feed entering the crushing chamber should not be separated, but should be fully mixed and uniform. When larger stones point to one side of the crushing chamber and smaller stones point to the other side of the crushing chamber, the feed may become separated. In this case, smaller stones will have a higher packing density, which can lead to a condition known as "packing" or "clumping." The pac
Limit the height and speed of feed descent
The maximum distance the feed material should fall into the top of a small to medium cone crusher is three feet or one meter. When the feed material falls much farther than it should, the gravel will hit the "V"-shaped crushing chamber at a certain speed, causing the crusher to withstand impact loads and extremely high stress levels. This situation is called "high-speed wedging". High-speed wedging can cause power overload or forced overload, o
Factors affecting the service life of the crushing wall and rolling mortar wall
The crushing wall and the rolling mortar wall are the main components that work together in the cone crusher and crush the materials. When the cone crusher is in operation, the crushing wall will make a trajectory movement, sometimes approaching and sometimes far away from the rolling mortar wall. The material is crushed by multiple extrusions and impacts from the crushing wall (moving cone) and the rolling mortar wall (fixed cone). , at this time part of the material wil
Determine the percentage of fines in the feed
"Fines in crusher feed" is defined as material entering the top of the crusher that is already equal to or smaller than the crusher's closed side discharge setting. As a rule of thumb, the maximum number of fine particles in the crusher feed should not exceed 25% for secondary crushers and 10% for tertiary crushers. When there are too many fines in the feed, it is usually the result of a vibrating screen problem. The problem may be due to insufficient screen size or appropr
