Optimisation of stock preparation plants
PTS has longstanding experience gained from numerous process analyses of stock preparation plants covering all grade groups. The evaluation tool SC Stock Preparation developed by PTS makes it possible to reveal any existing potential in the stock preparation plant. If necessary, investigations can also cover the constant section.
Tasks:
- Reduced fibre losses
- Optimum quality of finished stock in terms of stickies, unwanted materials and brightness
- Increased efficiency of existing plant systems
- Development and evaluation of concepts for new plant systems
- High availability and maximum yield of plant systems
Solutions:
- Expected potential – situation regarding stickies: analysing the general situation regarding stickies
- Evaluation of stickies removal: comprehensive evaluation of all important process stages in terms of their removal efficiency of stickies, detection of weak points
- Deinkability: determining and improving the deinkability of print products by tests in the laboratory and pilot plant
- Optical properties: determining large and small dirt specks in stock preparation, forecasting the brightness of finished stock
- Fibre losses: assessing the amount and composition of major rejects, concepts for reject reduction
- Flotates: assessing the possible reuse of flotates in the process
- Screen basket abrasion: measuring the slot width and profile angle of worn screen baskets
- Sand: measuring and assessing sand loads in the stock preparation system
- Concept development for new plant systems: use of innovative solutions taking into account energy, environmental and cost aspects
