Clinker is produced in very large quantities from household waste incineration. On average, 1,000 kg of household waste generate 250 kg of dry residue. The clinker coming directly from the plant must be screened, crushed with an impact crusher and the metal removed. The regraded grain fractions must contain no unburned material or large non-ferrous elements.
