The cement manufacturing process frequently causes spillages of dust and other materials along the transport, transformation and storage lines. Sibilia explains why it is important to keep a cement plant clean and offers its advice on the most efficient ways to do so.
Spillages occur in a cement plant spite of the new adopted technologies and the efforts to maintain and renovate plant machinery. The spilt materials consist of raw materials, additives, fossil fuels, ash and cement itself. In a medium-sized cement plant the estimated average spillage is approximately 15tpd, representing considerable expense for companies in terms of:
- Reduced production
- Inefficient and non-continuous machinery service
- Increased risks of accidents and diseases.
These problems are mainly due to the complexity of the cement manufacturing process, to the wide variety of materials used and last but not least to the dimensions of the plant.
The legal aspect concerning the industrial emissions into the atmosphere must also be taken into account. In this respect the Directive 2008/1/EC states that all manufacturing sites – both new and already existing – must comply with the following:

In addition to the above, the main cement manufacturers also adopt the ISO 14000 certification that manages the control process and the environmental impact. It provides a framework for the development of an environmental management system and the supporting audit programme.
Nowadays keeping the work environment dust-free and clean is an indispensable reality in every step of the manufacturing and distribution process. he main reasons to clean a cement plant are:
In a multiple floor environment and large plants it is generally recommended to use fixed cleaning systems equipped with inlets connected near the collection points of the material.
