Manufacturing a Consistent High-Quality SRF December 8, 2018 Separation and Sorting Technology GALBALLY - The 3 key characteristics of manufacturing a consistent high-quality SRF product are particle size, calorific value and moisture content. If any of these characteristics are compromised, burning efficiency may be affected.In terms of SRF supply to cement plants, quality and consistency are important parameters for fuel performance. SRF suppliers are not specialists in the manufacture of cement and are not always fully aware of the impact of SRF quality on kiln welfare or the issues SRF may present to feeding equipment. To ensure consistent and high-quality SRF a sound understanding of the cement manufacturing process is the basis of successful SRF production. Input Waste Managing incoming waste quality is key to SRF manufacture because producing the right quality SRF requires the right raw materials. Understanding and managing the input raw materials (input waste) facilitates the production of a consistent quality SRF fuel. SRF Particle Size To achieve the optimum particle size shredding is probably the simplest step in SRF manufacture. But it is expensive. The smaller the particle size required, the lower the throughput and the higher the cost and wear is on a shredder. Shredder maintenance is key to ensuring that particle size stays within the agreed specification. Removing metals A common issue with SRF quality is the presence of foreign objects which can block feeding systems to the kiln or calciner, namely metals Although it might seem logical to remove such objects, as they are often associated with high recycling prices, removing metals can be an expensive process. Non-ferrous metal recovery requires special (expensive) equipment. In some case, recovered metals are frequently contaminated with paper, plastic or other objects resulting in high disposal costs. Moisture Levels It is very important to ensure the input streams are as dry as possible. High moisture levels not only have a negative impact on the kiln system, it causes blockages in the feeding systems and is the source of bad odours. Moisture often originates in paper and cardboard, which easily absorbs water and is very difficult to extract again, unlike plastics of which doesn’t absorb water. The easiest way to avoid moisture is to choose the right input material. A well- known source for moisture is municipal waste, especially if no sorting is carried out prior to processing. If any of 3 key characteristics, particle size, calorific value and moisture content are compromised, burning efficiency may be affected.
