Paper Machine Forming Part Breast Roll
The breast roll plays a vital role at the start of the forming part in a paper making machine. It supports the forming fabric and helps begin the dewatering process. A well-designed breast roll ensures that the pulp is spread evenly and that the paper web forms smoothly. Without a stable breast roll, the paper production line would face poor sheet quality and frequent breaks. It is a key piece of paper mill equipment that sets the foundation for the rest of the paper making process.
Our breast roll is built with high-quality materials for lasting performance. The roll body is made from a strong steel plate that is rolled and machined to the proper thickness. The end plates are securely welded with stainless steel to provide a tight seal. The journal is made of heat-treated steel and features a precise taper, along with a hydraulic release oil hole for easy maintenance. The surface of the breast roll is covered with wear-resistant diamond rubber to protect the forming fabric. It uses a cast iron bearing housing with grease lubrication. The breast roll also comes with a reliable lifting device. This device features reducer motors on both sides with a high protection level. It uses a copper worm wheel and a stainless steel screw with a protective cover to ensure it never gets stuck.
