Hammer crusher pulley hub and associated with it spindle head, keyway, a situation occurs often wear. After the problem occurs, the Shanghai hammer crusher, using the traditional method to the hub reaming, after repair welding machining spindle head and keyway sizes. However, high temperature welding thermal stress generated can not be completely eliminated, in operation prone to off-axis, hammer crusher suppliers, causing a major accident. And demolition, welding, machining not only increase labor intensity, but also a large number of enterprises waste valuable production time. Western countries use more polymer composites hammer crusher wear on-site repair, in which the most mature technology is a blessing blue world. The use of polymer material, free removal, free machining field repair, hammer crusher equipment, low maintenance costs, short cycle, greatly reducing maintenance labor intensity; it has excellent mechanical properties, superior adhesion and will not high temperature stress, the device fully meet operational requirements. While good plasticity, can be sure that the shaft and hub mating surface 100% exposure, to avoid possible gaps again, well done Troubleshooting hammer crusher. The main purpose of material to be broken coal, salt, chalk, gypsum, brick, limestone. Also for crushing fiber structure, strong flexibility and toughness of broken wood, paper or broken asbestos cement waste to recover asbestos fibers and so on. In addition, hammer crusher not only can be used for crushing production line imported hammer crusher, sand production line, also can replace cone crusher in beneficiation production line. Ring hammer crusher for crushing all kinds of hard and abrasive weak materials. The compressive strength of the material does not exceed 100MPa, moisture content less than 15%. Material to be broken coal, salt, chalk, gypsum, brick, limestone. The main working parts ring hammer crusher rotor with a hammer (also known as hammer) is.
