Pulp & Paper Conveying Equipment

Paper products are made from wood pulp, cellulose fibers or recycled newsprint and paper. Wood chips and many different chemicals are used in the paper making process. These bulk materials are conveyed, metered, elevated and stored using equipment made by KWS. Our equipment is ideal for the pulp and paper industry. We regularly manufacture using corrosion-resistant alloys such as 317L and Hastalloy. Tree bark is a by-product from the paper making process and is used as a fuel to fire boilers for the pulping process. The bark is extremely abrasive and requires special design considerations. KWS designs and manufactures bark bins and live-bottom feeders using chromium carbide surfaced plate to resist abrasion.
