15-02-2007 0183 32 I think you heat limestone to make lime, but it takes an external fuel From past experience working with hopper cars, I know it varies a lot as to how free-flowing it is Larger rock without the fines will flow pretty well Stuff with the fine material, especially when wet, is more of a problem...

• ### Retrofitting bins, hoppers, and feeders to solve flow problems - Know More

hopper typically requires a hopper angle 10 degrees less steep than a cone-shaped hopper to achieve mass flow Also, since a plane-flow hopper, such as the transition hopper shown in Figure4, has an elongated material outlet, the outlet width can be half that of a cone-shaped hopper without causing material bridging When using a plane-flow ....
