This instrument is designed to integrate into either a new or an existing conveyor belt line and analyze the composition of the raw materials used in the cement manufacturing process that are being transported by conveyor. The system analyzes the entire material stream and is not subject to errors and costs associated with material sampling.
Stockpile Management
One of the most popular uses of crossbelt online analysis systems is to monitor and control stockpile chemistry to meet quality targets, thus ensuring smooth kiln operation and providing flexibility in quarry operations. Whether the stockpile is longitudinal or circular, the CB Omni allows the cement producer to achieve consistent stockpiles, with minimal variations within and between piles. For stockpile management, the CB Omni system can be coupled with process control software to monitor and control the chemistry of the pre-blending stockpiles.
The process control software can be used in either “Manual” mode or in “Automatic” mode. In a “Manual” mode, the software is used to suggest proper proportioning of various raw materials available in the quarry to meet the quality control requirements of the blending pile. Control is achieved by assisting with the dispatch and direction of mining and haul operations. “Automatic” mode process control software can be used in applications where the quarried raw materials are measured into the process by means of controllable feeder. The software automatically adjusts the proportioning of the materials based on the cumulative chemistry in the stockpile and the current material analysis.
Raw Mix Proportioning Control
A primary determinant of kiln efficiency is the quality and uniformity of the raw material feed (“kiln feed” or “raw meal”). Maintaining kiln feed at quality specification with minimal deviation is a function of how precise, accurate and quickly the raw mix proportioning circuit can be controlled. Located downstream of the last raw mix component addition, a CB Omni system provides the precise control needed to minimize raw mix variability and keep it at quality specification while at the same time minimizing raw material costs and satisfying multiple quality control targets. Some of the benefits of having a CB Omni for full stream, high frequency raw mix proportioning include:
- Reduced size of homogenization silos
- Elimination of active blending in homogenization silos
- Higher efficiency use of purchased additives to help minimize costs
- Automate a manual process
- Reduced kiln fuel costs associated with material variability
- Energy savings from clinker grinding costs
- Increased life time for kiln refractory
- Reduced plugging conditions
