Problems solved by technology

[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. Because the contact area between the crushing roller and the material is small, the output has been low and the efficiency is relatively high. Low

Embodiment 1

[0024] As shown in Figure 1-4, it is a roller crushing device, which includes a set of main shafts. Zigzag-shaped protrusions 1b and depressions 1a, the protrusions 1b and depressions 1a are distributed in waves along the axial direction of the crushing roller, and the protrusions 1b and depressions 1a on two adjacent crushing rollers coincide with each other and leave a gap; Several convex ridges 4 are provided on the convex and concave surfaces; the above-mentioned crushing roller is composed of several disc knives 3 set on the main shaft 2, and the protrusion 1b and the concave 1a are formed by toothed The outer edges are arranged continuously in the direction of the main axis, and the disc cutter 3 can be scattered parts, as shown in Figure 2-4, so as to facilitate partial replacement; it can also be multiple or even all connected to form a disc cutter assembly , in order to adjust the axial position.

Embodiment 2

[0026] As shown in Figure 5-9, there is another roller crushing device, which includes two main shafts 2 arranged parallel to each other, and crushing rollers 1 are respectively arranged on the main shafts 2, and several protrusions 1b and depressions 1a are arranged on the crushing rollers 1. The protrusions 1b and depressions 1a are distributed in trapezoidal waves along the axial direction of the crushing rollers, and the protrusions 1b and depressions 1a on two adjacent crushing rollers coincide with each other and leave gaps. As shown in Figure 6-8, the trapezoidal wave can be formed by several disc cutters 3 whose outer edges are positively trapezoidal, and the outer surface of the disc cutter 3 can be provided with raised ridges; as shown in Figure 9, the trapezoidal wave It can also be formed by arranging several disc cutters whose outer edges are inverted trapezoids; the difference is that each disc cutter 3 of an inverted trapezoid must be an independent single piece,...

Embodiment 3

[0028] As shown in Figure 10, it is the third type of roller crushing device, which includes a group of main shafts, which are composed of a plurality of main shafts 2 arranged parallel to each other, and crushing rollers 1 are respectively arranged on the main shafts 2, and several convex rollers are arranged on the crushing rollers 1. Protrusions 1b and depressions 1a, the protrusions 1b and depressions 1a are distributed in waves along the axial direction of the crushing roller, and the protrusions 1b and depressions 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...
