In production, crushing is one of the essential processes to achieve "zero discharge" of steel slag. Commonly used for primary crushing of steel slag Crusher It is a hydraulic jaw crusher, but it is prone to "steel jamming", low resource utilization and high energy consumption. In order to face the above problems and improve the crushing efficiency of steel slag, inertia cone crusher can be selected as the crusher of steel slag crushing process. This machine is different from traditional ones in iron passing and selective crushing Crushing equipment It has obvious advantages, especially suitable for fine crushing of steel slag.
When crushing the steel slag, the small rigid blocks in the steel slag are flattened and discharged from the crushing chamber. The general steel blocks are as follows Bolt It will also be flattened and discharged from the crushing chamber. If unbreakable objects such as shovel teeth are mixed in the material, since there is no rigid connection between the moving cone and the transmission mechanism, the moving cone is stuck, and the vibration exciter will continue to rotate around the moving cone shaft, without damaging the transmission mechanism and the host machine. At this time, as long as the machine is shut down, find the object from the observation hole around the crusher, cut it with gas cutting, and then continue to start the machine. There is no need to empty the crushing chamber, because the inertia cone crusher can be started with full feed and load.
The compressive strength of steel slag is 169~306MPa, and the Mohs hardness is 5~7. Compared with the inertia cone crusher, the steel slag is only a medium hardness material, which is easy to break. Due to the different particle strength of "steel" and "slag" in steel slag, "slag" in steel slag is broken during selective crushing, while "steel" is flattened under the action of crushing force due to its calendering property, and discharged together with the crushed "slag". Due to the large crushing ratio of inertia cone crusher, it can crush the steel slag to a finer particle size and fully separate the "steel" and "slag" in the steel slag.
In addition, since the inertial cone crusher is full of feed, no feeder is needed, and the product size is fine Vibration sieve The closed circuit can simplify the steel slag grinding process, reduce the number of auxiliary equipment, and greatly save the investment in equipment and infrastructure.
To sum up, the inertia cone crusher is used as the crusher in the steel slag crushing process, which can improve the iron recovery rate in the steel slag. The energy consumption is low, and the tail slag is easy to handle. It has become the preferred equipment for steel slag crushing.
