Different machines to meet all needs
Given the low probability of growth in demand for cement over the long term, it is necessary to increase the amount of waste consumption to secure a specified volume of processed waste. Furthermore, the industry must facilitate efforts to prevent global warming. Therefore, the comprehensive material design of cement, in consideration of both environmental impacts and properties, is expected to ...

Thirty years ago, cement companies started to treat waste as a source of raw material and energy. Today, the cement industry provides a significant contribution to the waste management practices of many countries. The responsible use of waste as an alternative fuel to heat cement kilns is lowering the industry's consumption of fossil fuels, which is helping to reduce the environmental ...

The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete. These can also be used as clinker raw materials, or processed into cementing systems. New grinding and mixing ...
