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

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.
