Mechanical systems such as cyclones trap the larger particulates in kiln gases and act as preconditioners for downstream collection devices. Electrostatic precipitators (ESPs) and fabric filter systems (baghouses) are the principal options for collection and control (achieving over 99% removal efficiency) of fine particulates.

Logical Dynamic (MLD) systems but at Jura Cement, this was applied for the first time to a cement mill. MLD systems had been applied elsewhere in the cement industry, to control kilns and raw mix for example, but this was the first known application of this technology on a cement mill. MLD systems were recently developed
