For many recycling plants and factories, one of the most frustrating issues in daily operation is material jamming—when shredded waste gets stuck between the shafts, causing equipment downtime and even motor overload. At Haishihong Machinery, we’ve developed several design features and operating tips to help users avoid this common headache.

Our SSJ series, especially the SSJ-800 dual-shaft shredder, comes equipped with automatic reverse function, which detects resistance and reverses blade rotation to clear the jam. This significantly reduces the need for manual intervention and protects the gearbox and motor from damage.

Another key to preventing jamming is choosing the right blade structure for the material. For example, soft materials like plastic films or cloth are prone to wrapping around the shaft, while bulky items like cardboard may block the feed opening. With our modular blade design, customers can easily customize tooth shape, thickness, and spacing according to their material characteristics.

Additionally, we recommend feeding material evenly and avoiding sudden dumping of oversized waste. Installing a conveyor with speed control can help maintain a steady flow, which is essential for smooth operation.

By understanding the causes of jamming and taking preventative measures in design and operation, users can maximize uptime, extend equipment life, and improve shredding efficiency—turning a common problem into a manageable challenge.
