The mechanical and fixed knife of plastic crusher

The mechanical knife and the fixed knife are the main components of the plastic crusher, and the interaction between them directly affects the crushing effect. The shape, size and mechanical properties of the cutter and fixed cutter are the key factors affecting the crushing effect. Generally speaking, the fixed knife is subjected to greater wear, the knife blade is thinner, with higher elasticity and hardness, and the blade of the fixed knife is thicker, with better wear resistance and impact resistance. In the crushing process, the shear force and compression force generated between the moving and fixed knives break the plastic material into small pieces.

The gap between the moving knife and the fixed knife is also an important factor affecting the crushing effect. The appropriate gap can ensure that the plastic material can smoothly pass the gap between the moving knife and the fixed knife, and can also reduce the friction and wear between the moving knife and the fixed knife. Too much clearance leads to the plastic material can not be effectively broken, resulting in large particles, while too small clearance may lead to increased friction and wear between the knife and the fixed knife, the knife is easy to damage, increasing the cost of plastic breaking.

In the operation process, the appropriate blade should be selected according to different plastic materials and crushing requirements, and the appropriate gap should be adjusted. For example, for plastic materials with higher hardness, it is necessary to choose a knife with better toughness, and for plastic materials with better toughness, it is necessary to choose a fixed knife with better wear resistance. The same crusher knife and fixed knife material can sometimes be selected from different materials. In addition, it is also necessary to carry out regular inspection and maintenance, and replace the worn blade in time to ensure the common use of the crusher.

SHJ knife can provide a variety of solutions, the crushing knife materials for different plastics, such as tool steel, high speed steel, carbon steel and etc. Waiting for your communication.
