Stock Preparation Machines are used for preparing the stock for producing paper and paper products. Stock is a slurry produced from raw material like bagasse or recycled paper. This slurry undergoes several operations with different machines to transform into smooth pulp for paper manufacturing.
Machines Used for Stock Preparation in Paper Mills
Pulper: A large container where raw material is mixed with water and continuously stirred until broken into small pieces to extract fibers. Types include High-consistency, D-type pulper, Dilution Pulper, etc.
Disperser: Designed to disperse impurities and unwanted materials from stock. Parason offers Hot Disperser for higher capacity and Mini Disperser for lower capacity.
Deflaker: Obtains single individual fibers, making stock free and improving pulp consistency. Types include Hole, Ring, & Conical.
Refiner: Removes pulp impurities and improves quality. Parason manufactures Twin Disc Refiner, Conical Refiner, & Trapmagni.
Cleaner: Removes smallest impurities like sand particles, glues, stickies, dirt, pins, chips. Classified by consistency: high, low, and medium.
Screener: Various types for different consistencies and quantities.
Thickener: Removes excess water from pulp to achieve desired consistency. Parason offers Disc Filters, Gravity Thickeners, and Decker Thickeners.
Agitator: Keeps pulp in suspension and ensures uniform consistency in chests. Available in vertical and horizontal configurations.
Reject Handling: Manages rejected material from screening and cleaning stages. Includes reject compactors and sand separators.
Deinking System: Removes ink and contaminants from recycled paper to produce clean pulp for high-quality paper production.
