In the process of paper manufacturing, there are several stages involved including, stock preparation, approach flow, forming, drying, and final paper roll. Every stage uses special machinery engineered for special processes. Stock preparation paper machines are used at the initial stages of paper production.
In this blog, we will know about the stock preparation paper machines, which machines are involved in it, their working, and the top manufacturer for the stock preparation paper machines.
Stock preparation process in paper machine
Stock preparation is a crucial stage in paper production where raw materials like wood, recycled paper, and fibers are processed and refined. It is converted into a slurry in various stages which is called the stock.
This stock is further used for paper production in further process. The stock preparation paper machines can determine the final quality of the paper product as the stock’s quality directly affects the final paper quality. There are several stages in stock preparation and each stage contains a different stock preparation paper machine.

Stock preparation in the paper manufacturing industry involves many stages. These different stages include different stock preparation paper machines. Every stage processes the raw material and the slurry to give it different results as per their specifications.
The different stages of stock preparation involve pulping, cleaning, screening, refining, deinking, thickening, and others. Each stage gives the pulp a different characteristic as per the requirement.
Pulping: The starting of the stock preparation after getting the raw material is pulping. In the pulping process, the raw material is processed through the pulping machines to form a slurry called pulp for paper manufacturing. Depending on the raw material, the final product’s required quality, the consistency of the pulp, and other factors, different types of pulping machines for the paper industry are used.
Cleaning: One of the stages in the stock preparation where the contaminants are removed from the pulp to get the cleaner pulp is cleaning. Cleaning machines are very crucial in the stock preparation of paper machines as they help remove heavy or light contaminants from the pulp. It helps to remove any foreign material from the pulp that can compromise the quality of the final product.
Screening: The pulp screening machines are another important machine in stock preparation paper machines. The pulp is passed through the screen baskets inside which the rotor rotates at a uniform speed, the pulp is passed through different types of screen baskets depending on the quality needed.
Refiner: Another important machine in the stock preparation paper machine is the refiner. The refiners are the most important part of the paper manufacturing process and crucial equipment in the stock preparation paper machines.
Refiners are responsible for getting the required fiber strength in the pulp by refining the pulp with the help of refiner plates. This step determines the final strength and the quality of the final paper product.
Apart from this, there are several stock preparation paper machines like poly disc filter, thickener, and gravity thickeners.
