Whitehopleman provides a range of engineering services to support cement companies in the operation and maintenance of their cement factories.
These services range from quarry loading optimisation, through mill charge design, kiln shutdown planning and supervision, control system optimisation, spare parts sourcing and implementation to development of maintenance management systems.
Quarry Chemistry Control
Quality control starts with the extraction of the primary raw material and any locally mined secondary raw materials.
Raw mix design shows us what we need to do to control the quality of these raw materials. If we are controlling to a target CaO content (CaCO3) then we need to mix materials together from two loading points. If we also want to control to an MgO target then we must mix loads from 3 loading points. However, before we can do that we have to know the composition of the materials at each loading point.
Whitehopleman provides Microsoft Excel based quarry chemistry control systems to guide cement factory quarry management in achieving the required chemistry of the raw material delivered into the process.
These quarry chemistry control take into consideration that there are other priorities beyond material composition involved in raw material loading. Meeting production targets, cost minimisation and quarry development are also important.
