[0023] Example 1
[0024] As shown in Figure 1-4, it is a roller crushing device, which includes a set of main shafts. The set of main shafts is composed of two main shafts 2 arranged parallel to each other. The main shafts 2 are respectively provided with crushing rollers 1, and the crushing rollers 1 are provided with several Zigzag-shaped protrusions 1b and recesses 1a, the protrusions 1b and recesses 1a are distributed in a wave shape along the axial direction of the crushing roller, and the protrusions 1b and recesses 1a on two adjacent crushing rollers coincide with each other and leave a gap; The protrusions and depressions are provided with a number of ridges 4; the crushing roller is composed of a number of disc cutters 3 sleeved on the main shaft 2, and the protrusions 1b and depressions 1a are tooth-shaped on the disc cutter 3. The outer edge is continuously arranged in the direction of the main axis. The disc cutter 3 can be a scattered part, as shown in Figure 2-4, to...

[0025] Example 2
[0026] Figure 5-9 shows another roller crushing device, which includes two main shafts 2 arranged parallel to each other. The main shafts 2 are respectively provided with a crushing roller 1, and the crushing roller 1 is provided with a number of protrusions 1b and recesses 1a. The protrusions 1b and the recesses 1a are distributed in a trapezoidal wave in the axial direction of the crushing roller, and the protrusions 1b and the recesses 1a on two adjacent crushing rollers are mutually matched with a gap. As shown in Figures 6-8, the trapezoidal wave can be formed by successively arranging a number of disc cutters 3 whose outer edges are in a regular trapezoid shape. The outer surface of the disc cutter 3 can be provided with ridges; as shown in Fig. 9, the trapezoidal wave It can also be composed of several disc knives with an inverted trapezoid outer edge arranged in sequence; the difference is that each disc knife 3 in an inverted trapezoid shape must be an ...

[0027] Example 3
[0028] As shown in Figure 10, it is the third type of roller crushing device, which includes a set of spindles. The set of spindles is composed of multiple spindles 2 arranged parallel to each other. The spindles 2 are respectively provided with crushing rollers 1, and the crushing rollers 1 are provided with a number of protrusions. The protrusions 1b and the recesses 1a are distributed in a wave shape along the axial direction of the crushing roller, and the protrusions 1b and the recesses 1a on two adjacent crushing rollers coincide with each other and leave a gap.
