Unloading cement and fine powders

Cement locks itself in during discharge. Chalk, lime and apatite concentrate behave the same way. The answer is external vibration: the VH-500 on rail, the Rockhammer RH-200 in storage.

Why fine material stops flowing

Cement is a fine-grained material: as it discharges through the hatches of a cement railcar it compacts and locks itself in — external impact is required. The same happens with chalk, lime and apatite concentrate.

Why bolt-on eccentric vibrators are not enough

Bolt-on eccentric vibrators are the usual choice for railcars, but they do not help clean the railcar of residue. The VH-500 handles that on rail, and the Rockhammer RH-200 in storage.
