Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …

Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.
According to Coverdale, if you're crushing steel slag, you want to use a compression style crusher, and when you're crushing blast furnace slag, you can get away with impact style crushers from time to time. In a slag plant, you're after the metal. You want to be able to recycle it and sell it back to the mill.
Gasification or combustion of coal and biomass is the most important form of power generation today. However, the use of coal/biomass at high temperatures has an inherent problem related to the ash generated. The formation of ash leads to a problematic phenomenon called slagging. Slagging is the accumulation of molten ash on the walls of …
