oxygen supply system (on-site/off-site) depends on the specific need of the cement plant. Oxygen production itself leads to comparatively high additional power consumption. Surely; there are a number of plants using oxygen enrichment technique but still not commercially due to its high cost. If market demand exists with good prices
Concrete mixers should be protected by side railings to prevent workers from passing under the skip while it is raised. Hoppers into which a person could fall, and revolving blades of trough or batch - type mixers, should be adequately guarded by a grating. In addition to the operating brake, skips of concrete mixers should be provided
Concrete batching consists of producing concrete or concrete products by mixing cement with sand, rock, aggregate or other similar materials. In a concrete batching plant, the raw materials are mixed using a front end loader or overhead bin concrete batching techniques.
