Material placed in a silo is often in a static condition. It is placed inside and stored until it is ready to be reclaimed. With blending and homogenizing silos, the structures are expected to hold material as well as be a part of the cement production process. Material is placed inside and manipulated while in the storage space.

From the quarry to the material crushing treatment to the cement plant, the entire cement manufacturing process is more complicated. Moreover, the raw materials are highly abrasive and the processing temperature is very high, so different processes require different cement conveyor belts. ... Storing and homogenizing.

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints.

The Circular Homogenizing Stacker Reclaimer System (CHO) stacks Bulk Material in one ring-shaped pile. The Circular Stacker is located on the centre column, allowing rotation and luffing motion, hence building the material in a chevron or cone shaped shell. Its height above the top of the pile is kept at a minimum distance to reduce dust emission.

Fly ash cement was developed from a mixture of Portland cement and fly ash as a hydraulic binding agent. In laboratory investigations, fly ash cement was produced by homogenizing Portland cement, clinkers, and fly ash as well as by grinding Portland cement, clinkers, gypsum and fly ash together. The experiments indicate that grinding the components together gives higher compressive strength ...
