Application of fly ash drying equipment in concrete production

  Fly ash is the main solid waste from coal-fired power plants. It contains highly active silicon oxide and calcium oxide and can be used in the production of building materials such as cement, mortar, and concrete. Wet fly ash has a high moisture content, and direct use will affect the efficiency of subsequent processing. It cannot be used directly in cement production. Drying it with a fly ash drying equipment can reduce moisture and achieve resource utilization.

  Fly ash drying equipment is specially designed for processing fly ash and other industrial dust and waste residue. It adopts the downstream drying method, and provides high-temperature airflow through the hot air furnace to exchange heat with wet fly ash to achieve water evaporation. Its working principle is to transport fly ash into the drying drum through the belt feeder, and use the evenly distributed scraper to turn the fly ash so that the fly ash is fully in contact with the hot air to achieve the drying process of heat and mass transfer. The dried fly ash is discharged through the discharger to complete the drying process.

  The fly ash drying equipment produced by Zhengzhou Jiutian is characterized by high efficiency, energy saving, high degree of automation and environmental protection. It adopts hot air furnace technology for heating, drying drum for heat exchange, and is equipped with dust collector for ventilation and dust removal.

  After being dried, fly ash can be used as a concrete admixture. The active ingredients can react with calcium ions in cement to form hydrated calcium gel (C-S-H), which can improve the strength of concrete. In addition, using fly ash to replace part of the cement can reduce the consumption of raw materials and reduce production costs.

  By using fly ash drying equipment to efficiently dry fly ash, we can provide high-quality raw materials for the concrete industry and promote the development of green building materials. If you are interested in our equipment, please feel free to contact us.
