Cement is a traditional industry with high energy consumption. Fuel and power cost account for more than 50% of cement production cost. Because coal prices have nearly tripled since 2021, the fuel costs for cement plants have also increased, forcing the industry to raise cement prices to maintain profits.
One cement plant client used the SRF preparation system for industrial solid waste developed by Harden, to maintain its fuel costs even as coal prices rose. Operational in 2022, the system has produced 40,000 tons of SRF for the cement plant, saving nearly $5 million in coal costs.
The system uses dual-stage shredding, magnetic separation, dust removal and other processes to prepare industrial solid waste into SRF with discharge size less than 100mm, a production capacity of 15 tons per hour, shredding qualified rate of more than 95%, and thermal replacement rate is about 70%, which meets the basic needs of coal burning in cement kilns.
In the context of global carbon emission reduction, it is very important to promote green low-carbon circular economy, and how to do this is also a problem that cement enterprises have to consider. The SRF preparation system can not only make resource utilization of industrial solid waste generated in daily life and industrial production, improve resource utilization efficiency and reduce environmental pollution, but also reduces the cost of coal burning for enterprises and greatly improves the revenue and profit, which will be the only way for the future development of the cement industry to reduce coal, energy conservation and carbon emission reduction.
