Cone crusher for primary crushing
Cone crusher for primary crushing has less unbalanced rotating mass and less swing time than jaw crusher. Therefore, starting cone crusher is easy when you turn the drive motor. These mills can sometimes be put in the presence of divisibility of material in the workplace.
Therefore, purification of the working space of cone crushers for primary crushing (for example, the need for disassembly for inspection crusher or a change in the armor of the cones) can be made simple crushed species after cessation of the supply of fresh material. Manual dismantling the dam breeds may require only applies when the crusher very large piece of rock, which overrides the boot screen, or the formation of the arch over the hopper grinder. This work was performed using the same devices as in the jaw crushers.
Primary cone crusher
All manufactured so far cone crusher for primary crushing have a side discharge crushed product on the inclined tray. When crushing wet clay soils often occur on the surface of the little things sticking tray that holds discharge and cause accumulation of crushed material in the cavity above the chute, down to the bottom of the armor blunt cone. This can lead to mounting material in the annular gap between the end of the main frame and the bottom of a glass crusher head. As a result, the O-ring is raised and opens up access to the friction surfaces of dust.
Such an accumulation of material can occur not only during the fragmentation of wet clay ores or delayed by the tilt tray, but also when there is insufficient capacity of the conveyor outlet or with a large content of fines in the feed, falls in large chunks through the discharge gap.
Therefore, the engineer should make sure that all the material was unloaded without delay on the inclined tray on the conveyor. Otherwise, no, even the most reliable seal does not provide protection from the rubbing parts of the crusher penetration to him of dust, dirt and bits of crushed material. And this leads to damage or wear and rubbing parts to an emergency exit from the crusher building.
Wearing parts of the crushing cones
Wearing parts of the crushing cones less impact on the size of crushed product than that of a jaw crusher. Therefore, cone crushers, as a rule, do not have devices to control the width of the discharge opening. In a very small range, such adjustment may be made on the upper end of the shaft crushing cone (suspension node in the cone).
It should be noted that with a large wear of pouring eccentric, performance of cone crusher is greatly reduced. This is so that when worn filling is reduced eccentricity, and hence the scope of crushing cone swings. Therefore, the worn came to timely renew.
