Example Embodiment

[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.

Abstract

The rolling crusher comprises at least a set of main shaft, each comprising at least two main shafts in parallel position, crushing roll on the main shaft with several convexes and concaves in wave like distribution, with the adjacent convex and concave of two crushing roller matching with each other with gaps between them. The crushed material goes through the gap between the crushing rollers with pressing and tearing. It has low noise, high output, low energy consumption, feasible for the crushing of food and forage.

Description

technical field [0001] The invention relates to a machine for crushing materials. Background technique [0002] At present, there are mainly roller crushers, hammer mills, etc. used for grain, oil and feed crushing on the market. The roller crusher mainly rotates two pairs of rollers to generate extrusion force and crush the materials. The hammer mill mainly crushes the material through the high-speed rotation of the rotor; the hammer mill has a high speed, requires high dynamic balance of the rotor, and is very noisy. [0003] The roller crusher mainly includes two parallel main shafts arranged at the same horizontal position, and crushing rollers are respectively arranged on the main shafts. There are two types of crushing rollers: smooth rollers and toothed rollers with axial teeth. , during the working process, the two crushing rollers rotate in opposite directions, and the material passes through the gap between the two crushing rollers, and is crushed and crushed. Be...
