Abstract (en)
Roll (1,2) for a roller press comprises a cylindrical press roll having an outer cylindrical pressing surface for use with an opposing roll, and a plurality of wear-resistant surface members (studs) (6), whereby the studs are fixed to the roll and the free ends of the studs protrude radially from the surface of the roll, and whereby the spaces between the studs are filled with a matrix material (12) being softer than the hardest material of which the studs are made. According to the invention the matrix material is a composite material comprising a non-metallic, organic binding mass. The roll is therefore easy and cost-effective producible and allows the application of long studs and can furthermore easily be repaired on-site without using sophisticated process equipment. The final roll surface is smooth.
