single shaft shredder knife blade seat is used to bear the weight of the shredding machine knife rest, and the shredding machine knife rest contains the blade, the knife shaft, the sleeve and the cap, so the key part of the shredding machine is borne by the knife seat. We choose the thickened steel plate to be welded, and the side is welded with reinforcing bars to ensure the strength of the cutter block of the shredding machine.

Selection of size of Rotating knife blade:
35 * 35 * 25mm: When it is suitable for the size of the assembly, the amount of the amount is 20mm to 25mm;
40 * 40 * 25mm: The size of the normal knife is standard size, cutting general material;
80 * 80 * 30mm: Compare materials such as wood and tires.

Fixed knife blade for single shaft shredder: Shredding material with moving knife. According to the different models, the length of the fixed knife is different, and the fixed knife teeth correspond to the layout of the moving knife shaft.

Three types of shredder machine blade installation:

First: the knife base and the knife shaft are welded together, which is relatively firm. Usually, choose this type of knife and tool shaft.
The disadvantage is that the clearance between the fixed knife and the moving knife is relatively large, and the minimum size of the discharge can only be 30mm.

Second: the knife and the tool carrier are embedded in the rotating shaft, suitable for film woven bag type knife and the gap between the fixed knife is less than 1mm, can be used as a crusher.
Disadvantages: easy deformation, high processing cost.

Third: the tool rest is made into a body with the rotating shaft, which is suitable for the film woven bag type, and the knife is installed separately.
Disadvantages: easy deformation, high processing cost.

The single shaft shredder blade disk comprises a blade and a fixed disk, and the cutter disk is driven by the shaft to the blade for secondary transmission so that the later replacement of the blade is more convenient.

The single-shaft shredder blades are divided into moving and fixed knives and are mounted on a single-shaft shredder for smashing the material.
The moving knife, commonly known as the square knife, is a cube that is recessed from the side. The four corners of the protrusion are the cutting edge (the four corners can be replaced at 90°), and the center of the recess is provided with a tapping hole for fixing the blade to the shredder roller. Since the blade is working in rotation, the blade is Material technology has to pay attention to, generally, use cr12mov above materials as raw materials, hardness should not be lower than 56HRC. Take the 800 type shredder as an example. The number of square knives on one device is 48.

The fixed knife is much simpler than the moving knife. The fixed knife is a rectangular parallelepiped with a single-sided or bilateral 90-degree tooth edge. The size and quantity of the blade are determined according to the fixed knife.
