The pin required for the connection of the blades in SHREDDER Crushers is a bolt. It is very important that these parts in crushers are produced using precise and correct material. Since it locks the blades during operation, the slightest production error that may occur in the diameter or countersink will cause the blades not to fit in place or to be loose. However, the blades may break, the pin may loosen and dislodge and cause severe damage to your machine. Thanks to our P&D studies, we can minimise the risk of damage by eliminating bolt loosening with fibre and washer designs as well as standard clamping bolts. Please contact us for details and order.
