Paper Pulping Process
Paper is made from the cellulose fibres that are present in hardwood and softwood trees . Whether using wood or recovered paper, the first step is to dissolve the material into pulp, and this need pulper equipment. Regardless of the type of pulping process used, the wood or recovered paper is broken down into its component elements so that the fibres can be separated. The pulping results in a mass of individual fibres being produced. The fibres are then washed and screened to remove any remaining fibre bundles. The water is then pressed out and the residue is dried.
The pulp is then ready to be used directly or it can be bleached and made into white paper. In an 'integrated paper mill' the pulp will be fed directly to a paper machine. Alternatively, it will be dried and pressed into bales ready for use as a raw material in paper mills worldwide.
