Harden Machinery DWS system
In the field of solid waste treatment, it took Europe 30 years to go from primary "waste co-processing" to the application of "RDF alternative fuel", while it only took 10 years in our country.
>> From before 2015, solid waste was co-processed by borrowing various industrial kilns;
>> Between 2015 and 2019, various RDF alternative fuel equipment gradually appeared, as well as the innovative development of solid waste pretreatment technology, which made the preparation of RDF alternative fuel from solid waste begin to sprout;
>> The proposal of the dual-carbon policy in 2020 has accelerated the process of solid waste resource treatment, and more and more companies have begun to invest in the construction of solid waste RDF alternative fuel preparation projects.
Today, the RDF alternative fuel industry chain has gradually matured, including solid waste collection, transportation, RDF preparation, sales and other links to form a complete industrial system.
Among them, integrated RDF alternative fuel preparation technology has become the core of this industrial system.
In the field of RDF alternative fuel preparation, Harden has gained recognition from domestic and foreign users with its more than ten years of experience in the solid waste treatment industry and its "user-oriented" business philosophy. Based on the raw material characteristics of various types of solid waste and closely combined with the demand for alternative fuels entering the kiln.
Harden proposed the solid waste treatment concept of "Just Shred It, Thus Sort It", with the concept of "modularization, integration and automation"
The equipment is combined to launch a DWS alternative fuel preparation system that is more efficient, more energy-saving, environmentally friendly and compatible with a variety of industrial solid waste.
The Harden DWS system is different from other systems. Its overall design focuses more on "reducing the harmful elements contained in the final output and improving the stability of the RDF alternative fuel combustion in the kiln."
Through automated solid waste treatment processes such as "fine crushing + intelligent air separation + powerful magnetic separation", the Harden DWS system not only separates heavy substances, metals and other impurities from various industrial solid waste, but also greatly reduces the RDF of the finished product. The composition of hazardous elements in alternative fuels;
The light combustibles in solid waste are also prepared into more uniform and finer high-quality RDF alternative fuels, which have a lower heat loss coefficient when burned in the kiln and have less impact on the fluctuations of industrial kilns.
Currently, Harden has provided DWS system solutions for more than 200 projects around the world, covering different industries such as cement, electric power, paper industry, and solid waste environmental protection.

The rapid development of the solid waste RDF alternative fuel industry has brought about many standardization issues.
Which raw material is more suitable for preparing RDF alternative fuel? What is the calorific value of RDF alternative fuel to meet the standard? What is the impact of the composition of RDF alternative fuel on kilns?
Harden Machinery Ltd. believes: “High calorific value and few harmful elements are the specific manifestations of high-quality RDF alternative fuel, and it is also more in line with the current mainstream trend of reducing carbon emissions.
The Harden DWS alternative fuel preparation system is the preparation of high-quality RDF alternative fuel. Standard answer sheet for the program.”
