What is co-processing in cement kilns?


Co-processing is the use of waste material as raw materials or as a source of energy, or

both, to replace natural mineral resources and fossil fuels such as coal, petroleum and gas in industrial processes.


Benefits of co-processing in cement kilns:


The technology of co-processing solid waste in cement plant kiln is currently one of the most direct, most environmental friendly and most efficient disposal methods. Co-processing of waste in cement kilns provides benefits for both society and industry: CO2 emissions are lower than with fossil fuels, wastes are co-processed in an efficient and sustainable manner and the demand for virgin materials is reduced.


What solid wastes can be co-processed in cement plant kilns and what are can not?


The wastes that can be processed by cement plant kilns include hazardous wastes, industrial wastes (leather scraps, waste textiles, etc.), domestic wastes, sludge, waste tires and other solid wastes. However, radioactive waste, explosives and reactive waste, undisassembled waste batteries, waste household appliances and electronic products, mercury-containing thermometers, blood pressure monitors, fluorescent lamps and switches, chrome slag, unknown properties and unidentified waste is forbidden to enter the kiln for co-processing.


Zhongan offers versatile technology solutions based on cement kiln co-processing for different waste process.



1. Co-processing technology of cement kiln via Zhongan's vertical tower type hazardous waste pretreatment system


In the process of cement production, the cement plant kiln will generate a large amount of high temperature, waste heat and negative pressure. These unique resources create good conditions for the harmless treatment of hazardous waste. Compared with other treatment methods, cement kiln treat hazardous waste has the advantages of less investment, good effect and no secondary pollution, this is a new way to solve the dilemma of hazardous waste disposal in the world.


Zhongan unique design Vertical Tower type Hazardous Waste Pretreatment System is used for the first or twice grade shredding of hazardous waste and its packaging before harmless treatment of hazardous waste, so as to achieve the size required for incineration in cement kilns or recycling. The complete shredding system integrated the equipment and functions of lifting feeding, pre-crushing, fine crushing, finished product conveying, safety fire fighting, maintenance, etc. The system takes into account many advantages of safety, reliability, small footprint and good stability, it can not only process various hazardous waste materials, but also designed and integrated a high-quality fire protection system to realize the dual safety management of manual defense plus technical defense for the co-processing of hazardous waste in cement kilns, ensuring the safety, stability and environmental protection of the entire incineration system in the kiln. Low consumption and efficient disposal of hazardous waste.


Outlet size: 50-200mm, capacity: 3-25t/h.



2. Co-processing technology of cement kiln - domestic and industrial waste shredding, sorting and RDF/SRF technology

The domestic and industrial waste shredding, sorting and RDF/SRF system consists of conveying equipment, waste shredder, magnetic separator, wind sifter and dust collecting equipment. The system integrated conveying, shredding, sorting, and transfer modules. The mixed industrial waste and domestic waste are disposed of from large to small, from mixed to classified. The material is transported to the domestic waste and industrial waste shredder through the conveyor for pre-shredding and reducing the volume of the material; the shredded material enters the magnetic separator and the iron material will be separated and recycled; the material which remoed iron continues to enter the fine shredder to be shredded into the ideal size; the finely crushed material enters the RDF/SRF pelletizer and will be extruded into RDF/SRF high-density bio-pellets. The whole system is intelligent sorting and stable operation.


Outlet size: 50mm, processing capacity: 5-30t/h



3. Co-processing technology of cement kiln - waste tire shredding, wire separation and grinding technology

Waste tires are first drawn off the sidewall steel wires by hydraulic wire drawing machine, then sent to the tire shredder by conveyor for crushing& screening to produce reasonable size rubber blocks. The next step is wire separator to separate thin wires in the crushed rubber block, subsequently, the vibrating conveyor equipment performs vibratory screening, then the fiber separator and magnetic separator separate the fiber and steel wire from the shredded rubber powder, and finally the product under the sieve is the finished fine rubber particle& rubber powder. The entire waste tire disposal system is enclosed working in conveying, negative pressure dust reduction, energy saving and environmental protection.


Pre-shredding size: 50mm, processing capacity: 3-30t/h


Rubber powder fineness: 20-120 mesh, processing capacity: 1-10t/h
